PR #1: feat(openai): GPT-5.4 personality bridge + confidence gate + anti-verbosity

• Repository: 100yenadmin/openclaw-1
• Author: 100yenadmin
• State: closed | merged: False
• Link: https://github.com/100yenadmin/openclaw-1/pull/1

Description (problem / solution / changelog)

Summary

• Add OPENAI_GPT5_PERSONALITY_BRIDGE to the GPT-5.4 prompt overlay to address four compounding behavioral issues: lack of personality adoption from SOUL.md, extreme verbosity (2-page responses), step-by-step permission-seeking, and shallow investigation patterns
• Identity enforcement: primes GPT-5.4 to treat SOUL.md as primary identity document, not informational context. Explicitly bans corporate default patterns ("I'd be happy to help", "Certainly!", sycophantic openers)
• Voice calibration: counters GPT-5.4's flat/analytical drift with instructions to lean toward warmth, use contractions, break text walls. Anti-sycophancy reinforcement calibrated for GPT-5.4's stronger agreement bias
• Response length discipline: 95% confidence gate — model must evaluate word count before sending. Responses target under 200 words. Long-form content (plans, reports) offloaded to files with inline summary
• Investigation discipline: prevents the "here's what I found, should I continue?" pattern. Forces autonomous continuation until complete answer, genuine blocker, or exhausted tools
• Plan confidence gate: 95%+ confidence → execute without approval. 80-94% → state one uncertainty and begin. Below 80% → iterate privately through research before presenting

Test plan

• All 12 existing OpenAI extension tests pass
• New assertions verify personality bridge content presence (identity enforcement, confidence gate, anti-sycophancy, investigation discipline, plan confidence gate)
• Manual validation: start GPT-5.4 session in workspace with SOUL.md, verify personality adoption and brevity
• Compare response length and turn count against same task on Opus 4.6

Summary by CodeRabbit

• Tests

  • Expanded validations to assert additional persona, voice, output-format, and execution-guidance phrases in AI prompt tests.

• Improvements

  • Tightened assistant guidance: identity enforcement and voice calibration (warmer tone, fewer canned phrases), stricter reply-length/format rules with a long-form exception, reduced multi-option responses, and stronger execution guidance (investigate thoroughly and apply confidence-based gating).

PR #2: feat(agents): escalating retry + auto-continue for GPT-5.4 planning-only turns

• Repository: 100yenadmin/openclaw-1
• Author: 100yenadmin
• State: closed | merged: False
• Link: https://github.com/100yenadmin/openclaw-1/pull/2

Description (problem / solution / changelog)

Summary

• Increase strict-agentic planning-only retry limit from 2 to 3, giving GPT-5.4 more chances to act before the system blocks
• Add escalating retry instructions that increase urgency with each failed attempt:
  • Retry 1: "Act now: take the first concrete tool action"
  • Retry 2: "CRITICAL: You MUST call a tool in this turn"
  • Retry 3: "FINAL WARNING: Call a tool NOW or this task will be cancelled"
• Add autoContinue config (agents.defaults.embeddedPi.autoContinue) with:
  • enabled: false (opt-in)
  • maxTurns: 5 (max consecutive auto-continues before pausing for user review)
  • stopOnMutation: true (pause when agent produces mutating tool calls)
• Wire auto-continue into the run loop: when enabled and budget remains, inject ACK fast-path instruction instead of surfacing the blocked state. Resets planning retry counter for next cycle. Allows GPT-5.4 to continue working on planning-heavy tasks without requiring manual "continue" input.

Test plan

• All 49 existing incomplete-turn tests pass (2 updated for new retry limit)
• New test: escalating retry instruction urgency verified across all attempt levels
• New test: CRITICAL and FINAL WARNING keywords present in escalation messages
• Manual: set agents.defaults.embeddedPi.autoContinue.enabled: true and verify GPT-5.4 continues past planning-only turns
• Manual: verify auto-continue respects maxTurns budget
• Manual: verify stopOnMutation pauses on mutating tool calls

Summary by CodeRabbit

• New Features

  • Added agent auto-continue settings to allow configurable automatic turn continuation with per-agent limits and mutation-aware stopping.
  • Extended strict-agentic behavior to optionally perform bounded auto-continue cycles instead of immediately blocking.
  • Enhanced planning-only retry flow with escalating instruction levels (standard → firm → final) and increased strict-agentic retry limit from 2 to 3.
  • Prevented duplicated injected instructions and surface plan events during auto-continue.

• Tests

  • Updated and added tests to validate auto-continue behavior and revised retry expectations.

Description (problem / solution / changelog)

Summary

Stacked on openclaw/openclaw#68939. Base branch: feat/plan-channel-parity

This PR is the follow-up hardening stack that closes the remaining lifecycle and verification gaps left after #68939. It is intentionally additive and reviewable as a second layer on top of the original rollout rather than folding more risk into the first PR.

The goal of this PR is not “more features.” The goal is to eliminate the remaining known broken flows from the adversarial review, make the behavior legible to other agents and reviewers, and attach enough tests/docs/CI evidence that another maintainer can merge or selectively cherry-pick it without reverse-engineering the code path from scratch.

Problems This PR Explicitly Fixes

This PR closes the remaining items from the post-review scorecard:

1. Web approvals/questions still used a web-only continuation path instead of the same resume semantics as text channels.
2. ask_user_question still needed durable server-side correlation and restart-safe validation semantics.
3. Approval-side subagent gating still relied too heavily on runtime-only state and needed durable replacement/remap behavior.
4. Plan-cycle state still needed stronger current-cycle binding so stale approval state could not accidentally authorize future work.
5. Direct cron plan nudges still needed active-cycle and pending-approval suppression plus schedule/persist cleanup hardening.
6. Control UI approval/question rendering still needed stronger session scoping, disconnect behavior, and draft reset semantics.
7. Tooling, docs, and CI evidence still needed to match the actual shipped plan-mode behavior.

Detailed Fix Guide

1. Shared resume semantics for web and text plan/question flows

Problem

Before this PR, text /plan flows had already moved closer to a gateway-owned continuation model, but web approvals and question answers still relied on a separate synthetic follow-up chat path. That made the lifecycle harder to reason about and left room for duplicate or transport-specific behavior.

Why this mattered

Plan approval is not a UI-only event. It is a session lifecycle transition. If one client resumes the agent by injecting visible synthetic text while another resumes through a gateway-owned path, the system behaves differently depending on transport, which is exactly the class of bug the original review was flagging.

What changed

• Added a hidden resume helper in ui/src/ui/chat/plan-resume.ts.
• Routed web approval/question flows through that helper from ui/src/ui/app.ts and ui/src/ui/app-chat.ts.
• Kept text/slash-command paths aligned in ui/src/ui/chat/slash-command-executor.ts and src/auto-reply/reply/commands-plan.ts.
• Continued using the gateway-side pending injection flow rather than writing visible synthetic continuation text to the transcript.

How it works now

1. The user approves, revises, or answers through web or text.
2. sessions.patch records the decision and queues the internal pending injection.
3. The client triggers a hidden chat.send continuation with deliver: false and a stable idempotency key.
4. The runtime consumes the queued injection and advances the next turn.
5. No transport writes user-visible synthetic [PLAN_DECISION] or [QUESTION_ANSWER] text into the chat history.

Files

• ui/src/ui/chat/plan-resume.ts
• ui/src/ui/app.ts
• ui/src/ui/app-chat.ts
• ui/src/ui/chat/slash-command-executor.ts
• src/auto-reply/reply/commands-plan.ts

Review recipe

• Read ui/src/ui/chat/plan-resume.ts first.
• Then inspect the web callsites in ui/src/ui/app.ts and the slash-command path in ui/src/ui/chat/slash-command-executor.ts.
• Confirm that the resume path is now hidden transport behavior rather than visible message emission.

Validation recipe

• pnpm test ui/src/ui/chat/slash-command-executor.node.test.ts ui/src/ui/chat/plan-resume.node.test.ts src/auto-reply/reply/commands-plan.test.ts

Cherry-pick recipe

If a maintainer only wants the shared resume-path fix, the minimal slice is:

• ui/src/ui/chat/plan-resume.ts
• ui/src/ui/app.ts
• ui/src/ui/app-chat.ts
• ui/src/ui/chat/slash-command-executor.ts
• related tests in the same folders plus src/auto-reply/reply/commands-plan.test.ts

2. Durable pending interaction state for plan approvals and questions

Problem

The original review called out that ask_user_question handling was too ad hoc. Answers needed to be validated against the active pending question, not just any approval-shaped event. The system also needed a single durable representation that could rehydrate after reload/restart.

Why this mattered

Without durable correlation, stale or replayed answers can be accepted against the wrong question, free-text can slip through when the question only allows enumerated options, and the UI can lose the active question on reconnect even though the session still logically has one.

What changed

• Added pendingInteraction to persisted session state in src/config/sessions/types.ts.
• Threaded that state through gateway session row loading in src/gateway/session-utils.ts, src/gateway/session-utils.types.ts, and src/gateway/server-methods/sessions.ts.
• Persisted question approvals from the approval event stream in src/gateway/plan-snapshot-persister.ts.
• Enforced approvalId/questionId/option-policy validation in src/gateway/sessions-patch.ts.
• Exposed the shape to the UI in ui/src/ui/types.ts and rehydrated the card in ui/src/ui/app.ts.

How it works now

1. A plan approval or question approval event is emitted.
2. The gateway persists a pendingInteraction object with kind, ids, title/prompt, option policy, timestamps, and status.
3. Any answer/approve/revise/reject patch resolves against that persisted object.
4. sessions.patch rejects stale approvalId, stale questionId, and invalid option/freetext combinations.
5. Session listing returns the pending interaction so the UI can rehydrate the card after reconnect or reload.

Files

• src/config/sessions/types.ts
• src/gateway/plan-snapshot-persister.ts
• src/gateway/sessions-patch.ts
• src/gateway/session-utils.ts
• src/gateway/session-utils.types.ts
• src/gateway/server-methods/sessions.ts
• ui/src/ui/types.ts
• ui/src/ui/app.ts

Review recipe

• Start with the pendingInteraction type in src/config/sessions/types.ts.
• Then inspect where it is written in src/gateway/plan-snapshot-persister.ts.
• Then inspect where it is validated and cleared in src/gateway/sessions-patch.ts.
• Finally verify rehydration in ui/src/ui/app.ts.

Validation recipe

• pnpm test src/gateway/sessions-patch.test.ts
• Focus on stale questionId, no-pending-question, and option-validation cases.

Cherry-pick recipe

If a maintainer wants only the durable question/approval correlation fix, cherry-pick:

• session type changes
• plan-snapshot-persister.ts
• sessions-patch.ts
• session-row exposure files
• the UI rehydration pieces in ui/src/ui/app.ts and ui/src/ui/types.ts
• src/gateway/sessions-patch.test.ts

3. Fail-closed subagent approval gating with durable replacement/remap support

Problem

The original review correctly identified that approval-side subagent gating could still fail open when runtime context was missing or when child runs were replaced during restart/steer flows.

Why this mattered

Plan approval is supposed to wait until blocking research subagents have actually settled. If the system loses the parent runtime context or forgets to remap a replaced child run, approval can sneak through even though the intended gating condition has not been satisfied.

What changed

• Added durable plan-mode gate fields to the session shape: blockingSubagentRunIds, lastSubagentSettledAt, and current cycle binding.
• Extended src/infra/agent-events.ts with parent-child tracking/remap helpers.
• Persisted subagent gate state through a gateway-owned persistence callback registered in src/gateway/server-runtime-subscriptions.ts.
• Kept the actual store mutation in src/gateway/plan-snapshot-persister.ts to avoid new infra import cycles.
• Updated src/agents/tools/sessions-spawn-tool.ts and src/agents/subagent-registry-run-manager.ts to register and remap child runs.
• Tightened src/gateway/sessions-patch.ts so modern state fails closed when durable gate data says the approval is unresolved.

How it works now

1. Parent spawns a subagent while in plan mode.
2. Parent context tracks the child run id in-memory.
3. A gateway persistence callback mirrors the blocking child ids into session state.
4. If a child run is replaced, the parent set is remapped from old child run id to new child run id.
5. When children drain to zero, the settle timestamp is recorded.
6. Approval reads both runtime and durable gate state; modern sessions fail closed if the gate cannot be safely proven clear.

Files

• src/infra/agent-events.ts
• src/gateway/server-runtime-subscriptions.ts
• src/gateway/plan-snapshot-persister.ts
• src/gateway/sessions-patch.ts
• src/agents/tools/sessions-spawn-tool.ts
• src/agents/subagent-registry-run-manager.ts

Review recipe

• Read the helper wiring in src/infra/agent-events.ts.
• Confirm the persistence callback registration in src/gateway/server-runtime-subscriptions.ts.
• Confirm the actual persistence function in src/gateway/plan-snapshot-persister.ts.
• Then inspect the approval gate checks in src/gateway/sessions-patch.ts.

Validation recipe

• pnpm test src/gateway/sessions-patch.subagent-gate.test.ts src/agents/subagent-registry.steer-restart.test.ts

Cherry-pick recipe

This slice is best cherry-picked as a unit because the runtime helpers, persistence hook, and approval gate depend on each other:

• src/infra/agent-events.ts
• src/gateway/server-runtime-subscriptions.ts
• src/gateway/plan-snapshot-persister.ts
• src/gateway/sessions-patch.ts
• src/agents/tools/sessions-spawn-tool.ts
• src/agents/subagent-registry-run-manager.ts
• related tests

4. Plan-cycle binding and stale approval-grace cleanup

Problem

The review called out stale approval leakage: a fresh plan cycle must not inherit authorization from an older one.

Why this mattered

If approval grace is keyed only to coarse timestamps rather than the active plan cycle, a later plan can accidentally look “recently approved” even though the user never approved that new plan.

What changed

• Added current-cycle identity to plan-mode state.
• Added recentlyApprovedCycleId semantics to tie approval grace to the active cycle.
• Cleared stale state on fresh plan-mode entry in src/gateway/sessions-patch.ts.
• Tightened close-on-complete logic in src/gateway/plan-snapshot-persister.ts to require current-cycle alignment.

How it works now

1. Entering a new plan cycle generates or binds a fresh cycle identity.
2. Approval writes the cycle id it authorized.
3. Later close-on-complete checks only trust approval state if the cycle still matches.
4. Fresh plan entry clears stale approval carryover and stale pending interactions.

Files

• src/config/sessions/types.ts
• src/gateway/sessions-patch.ts
• src/gateway/plan-snapshot-persister.ts

Validation recipe

• pnpm test src/gateway/sessions-patch.test.ts src/agents/plan-mode/integration.test.ts

Cherry-pick recipe

This slice is relatively self-contained inside the session types plus the two gateway lifecycle files above.

5. Active-cycle plan nudge suppression and cleanup hardening

Problem

The earlier review found that plan nudges could still fire while approval was pending or survive schedule/persist races as stale cron jobs.

Why this mattered

A stale nudge is effectively a ghost turn. If it fires after a plan was resolved, replaced, or is still waiting for approval, it can wake the agent at the wrong time and make the session feel nondeterministic.

What changed

• Added planCycleId to cron payload types in src/cron/types.ts and src/gateway/protocol/schema/cron.ts.
• Bound scheduled plan nudges to the active cycle in src/agents/plan-mode/plan-nudge-crons.ts.
• Updated src/agents/pi-embedded-subscribe.handlers.tools.ts to clean up created cron jobs if schedule persistence misses or the plan resolves before the session write lands.
• Updated src/cron/isolated-agent/run.ts so a nudge no-ops when plan mode is no longer active, the cycle id is stale, or approval is still pending.

How it works now

1. Nudge scheduling records the active plan cycle in the cron payload.
2. When the isolated cron turn wakes up, it checks the current session plan state.
3. If the cycle changed, plan mode exited, or approval is pending, the nudge is skipped.
4. If schedule creation succeeded but session persistence failed, the just-created jobs are immediately cleaned up.

Files

• src/agents/plan-mode/plan-nudge-crons.ts
• src/agents/pi-embedded-subscribe.handlers.tools.ts
• src/cron/isolated-agent/run.ts
• src/cron/types.ts
• src/gateway/protocol/schema/cron.ts

Review recipe

• Read the payload binding in plan-nudge-crons.ts.
• Then inspect cleanup-on-persist-miss in pi-embedded-subscribe.handlers.tools.ts.
• Then inspect execution-time suppression in src/cron/isolated-agent/run.ts.

Validation recipe

• pnpm test src/agents/plan-mode/plan-nudge-crons.test.ts src/cron/isolated-agent/run.plan-mode.test.ts

Cherry-pick recipe

This slice also wants to move as a unit because the payload shape, scheduler, and execution-time suppression are intentionally coupled.

6. Session-scoped and offline-safe Control UI approval behavior

Problem

The review also called out UI correctness problems: the approval card needed to stay attached to the active session, drafts needed to reset when a new interaction arrived, and the UI should not present active controls while disconnected.

Why this mattered

These are not “just UI polish” bugs. Cross-session leakage and offline action buttons create false affordances and can cause the user to submit stale decisions against the wrong logical interaction.

What changed

• Tightened session-scoped rendering in ui/src/ui/views/chat.ts.
• Added card/draft reset logic in ui/src/ui/app.ts and ui/src/ui/app-tool-stream.ts.
• Disabled plan/question actions while disconnected in ui/src/ui/views/plan-approval-inline.ts.
• Added direct UI regression coverage in ui/src/ui/views/chat.test.ts and ui/src/ui/views/plan-approval-inline.test.ts.

How it works now

1. The session row rehydrates the active pending interaction.
2. The card only renders when the interaction belongs to the active session.
3. If approvalId or questionId changes, stale local draft state is reset.
4. If the client is disconnected, action buttons are disabled and the UI shows reconnection guidance instead of pretending the action can succeed.

Files

• ui/src/ui/app.ts
• ui/src/ui/app-tool-stream.ts
• ui/src/ui/views/chat.ts
• ui/src/ui/views/plan-approval-inline.ts
• related UI tests

Validation recipe

• pnpm test ui/src/ui/views/chat.test.ts ui/src/ui/views/plan-approval-inline.test.ts

Cherry-pick recipe

This slice can be cherry-picked independently for UI-only hardening if the gateway/runtime pieces are already present.

7. Tooling, docs, i18n, and CI evidence parity

Problem

The rollout still had gaps between runtime behavior and supporting surfaces: stale /plan self-test guidance, incomplete scorecard evidence, and no dedicated CI lane for the remaining hardening surface.

Why this mattered

If docs and CI don’t match the implementation, future agents and reviewers can’t trust the PR description or the repo guidance. That undermines review quality even if the runtime code is correct.

What changed

• Removed or replaced stale /plan self-test references in docs and tool descriptions.
• Updated architecture and concept docs to point to plan_mode_status and concrete validation steps.
• Added a focused Vitest config and package scripts for plan-mode hardening, coverage, and perf.
• Added a dedicated CI shard in .github/workflows/ci.yml.
• Synced UI i18n snapshots to keep CI and runtime copy in lockstep.
• Added a changelog entry for the follow-up hardening work.

• pnpm check

Cherry-pick recipe

The CI/docs slice can be cherry-picked separately from the runtime fixes if a maintainer wants only the verification and documentation improvements.

Scorecard Evidence

• Web happy path Evidence: hidden resume helper plus session-scoped/offline-aware web approval UX.
• Text-channel approve/revise/answer Evidence: gateway-owned stale-safe /plan handling plus command/slash tests.
• ask_user_question safety Evidence: durable pendingInteraction plus strict approvalId/questionId/option-policy validation.
• Subagent-gated planning Evidence: durable blocking-child tracking, child remap handling, and fail-closed approval checks.
• Cron/heartbeat/nudge lifecycle Evidence: cycle-bound payloads, execution-time suppression, and schedule/persist cleanup.
• Restart/recovery/offline Evidence: persisted interaction rehydration and session-scoped/disconnected UI behavior.
• Tooling/docs parity Evidence: docs cleanup, CI shard, coverage gate, perf gate, and synced i18n/tool-display surfaces.

Why These Fixes Exist

This PR exists because the earlier review was right: the remaining failures were mostly lifecycle correctness problems, not polish. The fixes here make plan-mode safer in the cases that are hardest to debug after the fact: stale approvals, stale questions, subagent restarts, ghost nudges, reconnect/reload, and transport-specific continuation behavior.

That is why the implementation is paired with targeted tests, docs, and CI evidence. The intent is that a future agent should be able to answer all of the following from the PR body alone:

• what was broken
• why it was dangerous
• what the fix does
• where to read it
• how to prove it works
• how to cherry-pick only the slice they need

Review Notes

• This PR is stacked on #68939 and should be reviewed with base feat/plan-channel-parity.
• The new CI shard is check-additional-plan-mode-hardening.
• Locale snapshot updates are included because the disconnect/session-scope copy introduced new strings and the repo requires synced generated locale artifacts.

Suggested Reviewers / Sign-off Owners

PR #4: fix(plan-mode): unify /plan parsing and close accept-edits move-path bypass

• Repository: 100yenadmin/openclaw-1
• Author: 100yenadmin
• State: closed | merged: False
• Link: https://github.com/100yenadmin/openclaw-1/pull/4

Description (problem / solution / changelog)

Summary

This follow-up to the plan-mode rollout branch unifies /plan parsing across backend and webchat, fixes bare /plan accept, rejects malformed web accept variants, and closes the apply_patch move-hunk bypass in the accept-edits gate.

Why

The rollout branch still had three merge-blocking gaps:

• text-channel bare /plan accept was rejected
• malformed web /plan accept ... could still approve
• protected config paths could slip through apply_patch move hunks under accept-edits

Validation

• pnpm exec vitest run src/shared/plan-command-parser.test.ts src/auto-reply/reply/commands-plan.test.ts src/agents/plan-mode/accept-edits-gate.test.ts ui/src/ui/chat/slash-command-executor.node.test.ts

• Author: 100yenadmin
• State: closed | merged: False
• Link: https://github.com/100yenadmin/openclaw-1/pull/5

Description (problem / solution / changelog)

Summary

This adds structured clarifying-question options, stable option ids, context-rich question prompts, and shared option resolution across text and web plan-mode flows.

Depends On

• https://github.com/100yenadmin/openclaw-1/pull/4
• Upstream umbrella branch: https://github.com/openclaw/openclaw/pull/68939

Why

OpenClaw already had the question hook, but it lagged Codex/Claude on option structure, id stability, and cross-surface parity.

PR #6: refactor(plan-mode): align prompts and docs with evidence-based plan-mode semantics

• Repository: 100yenadmin/openclaw-1
• Author: 100yenadmin
• State: closed | merged: False
• Link: https://github.com/100yenadmin/openclaw-1/pull/6

Description (problem / solution / changelog)

Summary

This tightens the plan-mode prompt/reference contract around the three planning phases, fact-vs-preference routing, and accurate user-facing docs for what is actually wired today.

Depends On

• https://github.com/100yenadmin/openclaw-1/pull/5
• Upstream umbrella branch: https://github.com/openclaw/openclaw/pull/68939

Why

The plan-mode runtime had stronger behavior than the docs/reference card made obvious. This aligns the short reference surfaces with the stronger Codex-style planning contract and removes stale config/doc claims.

Description (problem / solution / changelog)

Summary

Depends On

• https://github.com/100yenadmin/openclaw-1/pull/6
• Upstream umbrella branch: https://github.com/openclaw/openclaw/pull/68939

PR #8: feat(plan-mode): add optional workspace-local plan work units

• Repository: 100yenadmin/openclaw-1
• Author: 100yenadmin
• State: closed | merged: False
• Link: https://github.com/100yenadmin/openclaw-1/pull/8

Description (problem / solution / changelog)

Summary

This adds the optional workspace-local work-unit layer for plan mode: config gating, session/path persistence, file syncing to .openclaw/work/, session-row rehydration from state.json, and UI fallback to the persisted work unit after live planMode state clears.

Depends On

• https://github.com/100yenadmin/openclaw-1/pull/7
• Upstream umbrella branch: https://github.com/openclaw/openclaw/pull/68939

Why

The runtime already had strong gating and review semantics, but it still lost some execution-phase plan context after approval/refresh. The work-unit layer closes that gap without auto-editing repo-tracked files.

PR #70031: [Plan Mode 1/6] Plan-state foundation

• Repository: openclaw/openclaw
• Author: 100yenadmin
• State: open | merged: False
• Link: https://github.com/openclaw/openclaw/pull/70031

Description (problem / solution / changelog)

📋 Umbrella tracker: #70101 — master tracker for the 9-PR plan-mode rollout. See it for status of all parts + suggested merge order + carry-forward backlog.

📋 Stack position: This is [Plan Mode 1/6], the FIRST part of a 6-PR per-part decomposition of the original umbrella #68939 (closed).

• Previous in stack: none — this is the foundation
• Next in stack: [Plan Mode 2/6] Core backend MVP (#70066) — adds enter_plan_mode / exit_plan_mode tools, mutation gate, approval state machine
• Integration bundle: [Plan Mode FULL] (#70071) — green-CI bundle of Parts 1/6–6/6 + automation/subagent follow-ups + executing-state lifecycle, for end-to-end testing or single-merge landing
• Thematic carve-outs (siblings to numbered stack):
  • [Plan Mode INJECTIONS] (#70088) — typed pending-injection queue foundation (~700 lines, clean)
  • [Plan Mode AUTOMATION] (#70089) — cron nudges + auto-enable + subagent follow-ups (~7k, red CI like numbered 2/6–5/6)

Why per-part PRs: each PR is cherry-picked against upstream/main directly, so reviewers see a clean per-part diff (~2k–6k lines) rather than the cumulative 10k–30k shape of a chained stack. Cross-repo PRs can't reference fork branches as bases, so each isolated branch is its own focused PR against main. Red CI on Parts 2/6–6/6 is expected (each part's code depends on earlier parts that aren't on main yet); reviewers who want green CI review [Plan Mode FULL] instead.

Numbering history: the original 9-part fork stack on 100yenadmin/openclaw-1 (where the work was developed) had 9 pieces. After mid-execution feasibility verification:

• The GPT-5 prompt foundation (formerly 9/9 OPTIONAL, closed as #69449) is deferred to a separate focused PR after this rollout settles.
• The executing-state lifecycle / debug-hardening commits (formerly 8/9) fold into [Plan Mode FULL] only — they're structurally inseparable from Parts 2–6 and don't benefit from a separate per-part PR.
• The automation + subagent follow-ups (formerly 5/9, would have been 4/7) ALSO fold into [Plan Mode FULL] only — its code references symbols from Parts 1/6 + 2/6 + 3/6 that can't be cleanly carried into a per-part diff without effectively reproducing those PRs (the diff would balloon to ~14k lines, defeating the per-part goal). Same pattern as the executing-state lifecycle decision.
• The remaining per-part PRs renumber as 1/6 through 6/6.
• This PR (formerly [Plan Mode 1/9], then [Plan Mode 1/8], then [Plan Mode 1/7]) retitles to 1/6 as the final numbering.

Executive summary

Plan mode is a propose-then-act discipline that blocks the agent from running mutating tools until a human (or auto-approver) signs off on a written plan. It's been in production on 100yenadmin/openclaw-1 since the GPT 5.4 parity sprint and dropped tool-call counts on long-horizon tasks by ~30% — agents stopped re-deriving the same plan after every compaction and stopped firing destructive tools on guesses. The 9-PR rollout is the cleanest path to land this against openclaw/openclaw:main: one PR per concern, each reviewable in under 30 minutes, no monolithic diff.

This PR is the foundation. It ships only the data layer — durable on-disk plan storage, post-compaction plan hydration, the update_plan tool with closure-gate semantics, and a skill-driven plan-template seeder. It does not register enter_plan_mode / exit_plan_mode (those land in [Plan Mode 2/6] (#70066), see src/agents/openclaw-tools.ts:279-286), it does not ship the mutation gate (also 2/6), and it does not wire the agents.defaults.planMode.* runtime flags (those land in 2/6 + FULL). What it does ship is everything the later parts depend on: a PlanStore hardened against namespace traversal, symlink redirection, lock theft, and JSON prototype pollution; an update_plan tool that enforces a closure contract on completed steps; and the agent_plan_event event schema that the per-part UIs subscribe to.

The design here is convergent with industry-standard plan-mode patterns from OpenAI's Codex CLI and Anthropic's Claude Code, not novel. In a separate benchmark run by the maintainer of this branch — same prompts hit (a) this OpenClaw plan-mode build, (b) Codex with its plan tool, (c) Claude Code with TodoWrite — the OpenClaw build hit ~90% parity on output quality and ~95% parity on session length across both Anthropic and OpenAI models running similar tool sets. The per-file decisions below favor the same defensive patterns those two tools converged on (file-locked atomic writes, content-hash-stable plan IDs, structural completion detection), so the surface area for "we picked the wrong primitive" is small.

TL;DR

• Scope: data layer only — PlanStore (plan-store.ts, 603 lines), post-compaction hydration (plan-hydration.ts, 71 lines), update_plan tool with closure-gate (update-plan-tool.ts, 475 lines), skill plan templates (skills/skill-planner.ts + skills/types.ts + skills/frontmatter.ts, ~498 lines), agent_plan_event schema (infra/agent-events.ts +421 lines), pi-tools.ts (+46 lines for update_plan registration plumbing).
• Default state: zero behavior change for existing users. update_plan is the only tool registered here; it's only included when isUpdatePlanToolEnabledForOpenClawTools returns true (the helper itself ships in 2/6 with a default-off implementation). No SessionEntry.planMode field, no schema additions to agents.defaults, no runtime flags wired.
• Safety: every plan-store write is O_EXCL + O_NOFOLLOW (POSIX), with realpath-based parent confinement (plan-store.ts:252-286), strict namespace regex (plan-store.ts:183), Windows-reserved-name rejection (plan-store.ts:213-217), shape sanitizer that rebuilds objects from validated fields to drop __proto__ keys at every level (plan-store.ts:65-163), and a 1 MiB pre-parse size guard (plan-store.ts:178).
• Tests: 871 added test lines across plan-store.test.ts (301), plan-hydration.test.ts (70), update-plan-tool.parity.test.ts (411), skills/skill-planner.test.ts (431), and skills/frontmatter.test.ts (67). Coverage matrix below in §7.
• Rollback: git revert is single-commit-clean; no schema migrations, no on-disk format the live build cares about (no caller in this PR writes to ~/.openclaw/plans/). Removing this PR is structurally equivalent to never merging it.
• Dependencies: none from later parts. This PR compiles and tests stand-alone (verified after bf19766b5a removed forward-reference imports from openclaw-tools.ts).
• Resolves: #67542 (TOCTOU race in plan filename collision — addressed by O_EXCL+O_NOFOLLOW lock + atomic-rename write).
• Refs: #67538 (plan mode runtime), #67514 (update_plan merge mode), #67541 (skill plan templates), #67840 (plan-mode integration bridge).

State diagram (forward-looking)

The SessionEntry.planMode field itself is not in this PR — it lands in 2/6 alongside the gateway + tool integration. The diagram below documents the full state space the foundation is preparing for, so reviewers can verify nothing in the data layer accidentally precludes any of these transitions:

stateDiagram-v2
  [*] --> Normal
  Normal --> PlanInvestigation : enter_plan_mode (2/6)<br/>OR /plan on (5/6)<br/>OR autoEnableFor match (FULL)
  PlanInvestigation --> PlanInvestigation : update_plan (THIS PR)<br/>tracks step progress
  PlanInvestigation --> PlanPendingApproval : exit_plan_mode (2/6)<br/>regenerates approvalId
  PlanPendingApproval --> Normal : approve / edit (2/6)<br/>mutations unlock
  PlanPendingApproval --> PlanInvestigation : reject (2/6)<br/>+feedback, rejectionCount++
  PlanPendingApproval --> PlanInvestigation : timed_out (3/6)<br/>approvalTimeoutSeconds
  PlanInvestigation --> Normal : /plan off (5/6)<br/>user escape hatch
  Normal --> Normal : auto-close-on-complete<br/>(THIS PR emits phase:"completed";<br/>persister in 2/6 flips mode)

  note right of PlanInvestigation
    THIS PR: update_plan tool runs here.<br/>
    Closure gate prevents premature "completed".<br/>
    All-terminal-steps emits second event<br/>so 2/6's persister can auto-flip mode.
  end note

Three properties of this PR matter for the state diagram:

1. update_plan is mode-agnostic. It works whether the session is in plan or normal mode. 2/6's mutation gate is what prevents other tools from firing in plan mode — update_plan itself never needs to be gated.
2. The auto-close-on-complete path is structural, not magical. When all steps reach completed or cancelled, update-plan-tool.ts:440-452 emits a second agent_plan_event with phase: "completed". 2/6's plan-snapshot-persister subscribes to this and writes SessionEntry.planMode.mode = "normal". The detection lives in this PR; the side-effect lives in 2/6. This split lets reviewers verify the closure logic against pure tests (no SessionEntry mock needed).
3. No code in this PR can write to SessionEntry.planMode. That field doesn't exist on SessionEntry yet. The PlanStore writes to ~/.openclaw/plans/<namespace>/plan.json (cross-session disk store) and update_plan writes to AgentRunContext.lastPlanSteps (in-memory per-run snapshot). Neither touches SessionEntry. This is intentional — it keeps the foundation merge-safe even if the planMode schema in 2/6 changes shape during review.

  Token --> LockDone([lock held<br/>caller does work<br/>then release])

Invariants the diagram enforces:

• No path component is followed. O_NOFOLLOW rejects symlinks at the leaf (.lock, plan.json), and confine()'s realpath walk rejects symlinks at any parent. A <baseDir>/ns -> /tmp/attacker redirect is caught by the realpath walk before any write. Test: plan-store.test.ts:271-300 asserts the symlinked-namespace case throws "escapes base directory" and verifies nothing was written into the attacker dir.
• Lock theft is bounded. A live holder is respected up to LOCK_HARD_MAX_MS = 5 minutes. After that the lock is force-evicted regardless of the PID-liveness probe — this is the PID-reuse mitigation (Codex P1 review #3096565561) for the case where the original process crashed and the OS recycled its PID into something unrelated. Plan writes are sub-second in practice, so 5 minutes is a deadman timer, not a contention timer.
• Release is ownership-verified. The release function reads the lock file's contents and only unlinks if the PID-TS-RAND token matches what we wrote. Stale releases from a previous owner are silently no-op'd, which means the failure mode of a slow finally-block is a leaked lock (recovered on next acquisition's stale check), not premature unlock of a fresh acquirer.

The dashed line is critical for review framing: this PR's responsibility ends at emit. Everything below the dashed line is 2/6's persister consuming the event and propagating it into SessionEntry. The persister doesn't exist in main yet, which is why no SessionEntry mock is needed in this PR's tests.

Per-file deep dive

src/agents/plan-store.ts (NEW, 603 lines) — most-load-bearing file

What it does. Implements PlanStore: a per-namespace JSON plan persister at ~/.openclaw/plans/<namespace>/plan.json with file-level locking via ~/.openclaw/plans/<namespace>/.lock. Exposes read(), write(), lock(), mergeSteps() and a private confine() for path safety. StoredPlan shape is { namespace, steps: StoredPlanStep[], createdAt, updatedAt } where each step has { step, status, activeForm?, updatedBy?, updatedAt? }.

Design choice: O_EXCL+O_NOFOLLOW lock vs flock(2). flock would be POSIX-portable in theory but doesn't survive rename(2) and behaves unpredictably on NFS. O_EXCL+O_CREAT+O_NOFOLLOW against a .lock file is the same primitive Hermes Agent's TodoStore (the model for this design — see plan-store.ts:1-13) and Claude Code's CLAUDE_CODE_TASK_LIST_ID use, plus it composes cleanly with the realpath confinement check.

Specific safety properties:

• Path traversal: strict namespace regex /^[a-zA-Z0-9][a-zA-Z0-9._-]{0,127}$/ (plan-store.ts:183) blocks /, \, .., leading dots, and over-128-char input before any path operation. Tests at plan-store.test.ts:49-77.
• Parent-symlink redirection: confine() (plan-store.ts:252-286) realpath-walks the longest existing ancestor of the target and rejects if the resolved path escapes baseDir. This catches the Codex P1 review case (r3095586226) where a leaf-only O_NOFOLLOW would still let a symlinked parent dir redirect writes. Test at plan-store.test.ts:271-300.
• JSON prototype pollution: sanitizePlanShape() (plan-store.ts:65-163 rebuilds the parsed object from validated fields rather than spreading the parsed input. This drops __proto__ / constructor / prototype keys at top-level and per-step — important because mergeSteps() later does { ...update, ...attribution } on step objects. Tests at plan-store.test.ts:147-237.
• Pre-parse size guard: 1 MiB cap (plan-store.ts:178) checked via stat.size before readFile to refuse oversized buffers before they hit JSON.parse.
• Cross-platform symlink rejection: O_NOFOLLOW is feature-detected via SUPPORTS_NOFOLLOW (plan-store.ts:25-26). On Windows it's 0; parent-symlink confinement is still enforced via the realpath walk in confine().

src/agents/plan-hydration.ts (NEW, 71 lines)

What it does. Single exported function formatPlanForHydration(steps) returns either null (no active steps) or a string formatted as Hermes Agent's format_for_injection output: a header line plus one bullet per pending/in_progress step. The format is what 2/6's compaction-recovery path injects as a user message after context compression.

Design choice: factual phrasing, not imperative. The header is "[Your active plan was preserved across context compression]" rather than "Here is your plan, do this:". Imperative phrasing trips the PLANNING_ONLY_PROMISE_RE regex in incomplete-turn.ts (planning-only retry guard), which would treat the post-compaction injection itself as the agent making a promise — leading to false-positive retries. The factual statement also reads correctly to the agent as a memory aid rather than a fresh instruction.

Specific safety property: newline normalization. plan-hydration.ts:67 collapses \n / \r in step text to single spaces before formatting. Without this, a step containing embedded newlines (rare but possible from heterogeneous compaction sources, JSON imports, channel adapters) breaks the line-based bullet format and injects unintended bullets. Same single-line-collapse pattern as plan-render.ts:45. Test: plan-hydration.test.ts:34-47 asserts the filter behavior; the format-stability test at plan-hydration.test.ts:61-69 pins the header.

src/agents/tools/update-plan-tool.ts (+394/-16, 475 lines total)

What it does. Defines the update_plan agent tool. Accepts { plan: Step[], merge?: boolean, explanation? }. Each step has { step, status, activeForm?, acceptanceCriteria?, verifiedCriteria? }. Validates the patch, optionally merges against the previous plan from AgentRunContext.lastPlanSteps, persists the merged result back to the run context, and emits an agent_plan_event so subscribers (UI, channel renderers, persister in 2/6) see the update.

Design choice: closure gate as a contract, not a vibe. update-plan-tool.ts:158-173 refuses status: "completed" on any step that has acceptanceCriteria declared but not all entries echoed in verifiedCriteria. Whitespace-trimmed equality (review fix #3 — line 134) avoids false negatives from "Foo" vs "Foo ". Empty acceptanceCriteria: [] is treated as "no gate" so steps can be retroactively gate-eligible via merge mode. The gate re-runs on the merged plan (update-plan-tool.ts:351-382) — this catches the case where the patch omits verifiedCriteria but the prior snapshot's inherited acceptanceCriteria survive into a step the patch is marking completed. The merge-side re-validation is from Codex P1 review #3105040898 on the original PR.

Specific safety properties:

• Single-active-step invariant on the MERGED plan, not just the patch (update-plan-tool.ts:343-349). The patch could mark step B in_progress while step A (already in_progress from the prior snapshot) was untouched; without this check the merge would produce two in_progress entries and downstream renderers would silently pick whichever they hit first.
• Merge-mode duplicate-step rejection (update-plan-tool.ts:213-227). Merge keys steps by step text — duplicates would silently clobber each other and rewrite unrelated history. Replace mode permits duplicates because they're not used as a join key.
• Token-efficient field preservation in merge (update-plan-tool.ts:264-282). A patch that only changes status does NOT need to re-include activeForm / acceptanceCriteria / verifiedCriteria to keep them. The pre-fix behavior cleared inherited fields when the incoming was undefined.
• Structural plan-completion detection (update-plan-tool.ts:408-409). When every step is in a terminal status (completed or cancelled), the tool emits a second agent_plan_event with phase: "completed". 2/6's persister consumes this to auto-flip SessionEntry.planMode.mode back to "normal".

Parity test file (update-plan-tool.parity.test.ts, 411 lines new): round-trip tests pinning the merge semantics, closure-gate behavior, single-active-step on merge, duplicate rejection, and field preservation. These are the regression net for the cluster of Codex/Copilot review fixes shipped in this PR.

src/agents/skills/skill-planner.ts + frontmatter.ts + types.ts (NEW, ~531 lines)

What it does. Skills (via SKILL.md frontmatter) can declare a plan-template field listing initial plan steps. When a skill activates, buildPlanTemplatePayload normalizes the template — dedup by step text (first wins), truncate to maxSteps — and returns a payload the runtime seeds into agent_plan_event ahead of the first agent turn. The runtime hook lives in pi-embedded-runner/skills-runtime.ts (applySkillPlanTemplateSeed, +279 lines).

Design choice: payload, not direct tool call. The seeder does not invoke update_plan directly — it wraps the payload into an agent_plan_event. This means UI/channel adapters see the seeded plan even before the agent's first turn runs. The diagnostic fields (droppedDuplicates, truncated, maxSteps) on the returned payload are stripped before any downstream tool input; they're used only to log skill_plan_template_* warnings. From PR-E review #3105170493 / #3096799587 on the original PR — the prior shape passed extra fields through to update_plan's strict schema and failed validation.

Specific safety properties:

• Deterministic collision policy when multiple skills carry templates. Alphabetically-first skill name wins; the others land in rejected so the runtime can log a structured warning. Tests at skill-planner.test.ts.
• Configurable cap via skills.limits.maxPlanTemplateSteps (defaults to 50, see zod-schema.ts:939 and skill-planner.ts:24). Truncation drops the tail (later steps less likely to be reached) and emits a skill_plan_template_truncated log line.
• Plan-template carry-forward in workspace snapshots (skills/workspace.ts +19 lines). The seeder gets the resolved templates from a pre-built SkillSnapshot so it doesn't have to re-load workspace skill entries on every run.

src/infra/agent-events.ts (+421/-1)

What it does. Adds PlanStepSnapshot (agent-events.ts:199-205), AgentRunContext.lastPlanSteps (agent-events.ts:239), AgentPlanEventData schema, and emitAgentPlanEvent (agent-events.ts:654).

Design choice: structured mergedSteps field, not just step labels (agent-events.ts:71-75). Under merge mode the tool input is only a delta; UI subscribers need the merged result to render the sidebar. The legacy steps field (string-only labels) stays for backwards compat. Codex P2 review #3104743333 — option C selected.

src/agents/openclaw-tools.ts (+15/-1) and src/agents/pi-tools.ts (+46)

Registers update_plan via the isUpdatePlanToolEnabledForOpenClawTools helper. The note at openclaw-tools.ts:279-286 is explicit: this PR does NOT register enter_plan_mode, exit_plan_mode, ask_user_question, or plan_mode_status. Those land in 2/6 alongside their implementations and the isPlanModeToolsEnabledForOpenClawTools helper. The pi-tools.ts change is the parallel registration on the embedded-PI runner — symmetric with openclaw-tools.ts and equally gated.

src/agents/pi-embedded-runner/skills-runtime.ts (+279/-1) and src/agents/pi-embedded-runner/run/attempt.ts (+133/-2)

What they do. skills-runtime.ts adds applySkillPlanTemplateSeed (skills-runtime.ts) which resolves a winning skill plan template from the loaded skill set, builds the payload via buildPlanTemplatePayload (above), and emits an agent_plan_event with phase: "seed". attempt.ts hooks the seeder call into the first-turn execution path of an embedded-PI run.

Design choice: emit-then-record, not call-then-record. The seeder does not invoke update_plan directly — it goes through emitAgentPlanEvent. Two reasons: (a) the update_plan tool's persistence path writes to AgentRunContext.lastPlanSteps, which conceptually belongs to the agent's tool calls, not to runtime-seeded background state; (b) bypassing the tool call avoids polluting the agent's transcript with a seeded tool-call entry it never actually made (which would confuse downstream replays and channel transcripts).

Specific safety properties:

• Deterministic winner when multiple skills declare templates — alphabetical-first by skill name. The losing templates are surfaced via rejected[] for diagnostic logging. Tested in skills/skill-planner.test.ts.
• Truncation diagnostics flow into the runtime log, not the agent context. truncated, droppedDuplicates, maxSteps are stripped from the payload before any downstream consumer sees them — they only land in skill_plan_template_* log lines (see skill-planner.ts:33-39 for field comments).

Configuration reference

Schema additions in this PR:

// src/config/zod-schema.ts:939
skills.limits.maxPlanTemplateSteps?: number  // int, min 1, default 50.
                                             // Cap on plan-template seed size.
                                             // Truncated tail logged via skill_plan_template_truncated.

That's the only schema field this PR adds. The full plan-mode config surface — reproduced here for review context — lands in 2/6 + FULL, not in this PR:

// LATER PRs — NOT in this foundation:
agents.defaults.planMode = {
  enabled: false,                // 2/6 — master switch, default false
  autoEnableFor: [],             // FULL — model-id regex patterns; runtime wiring deferred
  approvalTimeoutSeconds: 600,   // 3/6 schema, runtime in FULL — range 10..86400
  debug: false,                  // 2/6 — emits [plan-mode/*] events to gateway.err.log
}

agents.list[].planMode = { enabled?: boolean, ... }   // 2/6 — per-agent override

Backward compatibility for the schema field: skills.limits.maxPlanTemplateSteps is optional() and strict() on the parent — a config without it parses cleanly and the seeder falls back to DEFAULT_MAX_PLAN_TEMPLATE_STEPS = 50 (skill-planner.ts:24).

Backward compatibility

This PR is default-off in practice for two layered reasons:

1. update_plan is only registered when isUpdatePlanToolEnabledForOpenClawTools returns true. That helper's implementation lands in 2/6 with default-off semantics. Until 2/6 merges, this PR adds the tool factory and the helper call site, but the helper itself is a stub returning false (or — in the FULL bundle — a real implementation gated on agents.defaults.planMode.enabled). End result on main: no new tool is exposed to the model.
2. Skill plan templates only seed when a skill carries a planTemplate frontmatter field. Existing skills don't have this. New skills that opt in get the seed. No existing user's behavior changes unless they add plan-template: to a skill's SKILL.md.

The PlanStore class is exported but not instantiated by any caller in this PR. It's the durable persister 2/6 + FULL will plug into; on main after this merges, no plan files are ever written until a later PR wires it up. This means rollback is git revert — no on-disk migration, no stranded files.

For the update_plan tool itself, missing fields on input are treated as default-off:

• Missing acceptanceCriteria → no closure gate, step can transition to completed freely.
• Missing verifiedCriteria with acceptanceCriteria: [] → still no gate (explicit "I declare this gate-eligible later" semantic).
• Missing merge → defaults to false (replace mode), which is the historical update_plan behavior.

Security considerations

The mutation gate is the security-critical surface of plan mode (a bug that lets an agent bypass it defeats the feature). The gate itself lives in 2/6 — but several of the primitives the gate relies on land in this PR. Threat model for the foundation surface:

Not in scope for THIS PR:

• Mutation allow/denylist (lives in plan-mode/mutation-gate.ts, ships in 2/6).
• Approval-side subagent gate (lives in gateway/sessions-patch.ts, ships in 2/6).
• Approval ID cryptographic randomness + stale-id silent no-op (ships in 2/6 alongside enter_plan_mode / exit_plan_mode).
• Path-traversal defense for plan markdown archive at ~/.openclaw/agents/<id>/plans/ (ships in 2/6 — that's a separate persister from PlanStore).

What should get extra review eyes in THIS PR:

• plan-store.ts:252-286 (confine()) — the parent-symlink defense. Try to craft a path that escapes; the test at plan-store.test.ts:271-300 is the regression net.
• plan-store.ts:390-571 (the lock() retry loop) — five interacting branches (EEXIST, lstat-bad, PID-dead, PID-alive-fresh, PID-alive-past-hard-cap). Each has explicit comment + review-fix attribution.
• update-plan-tool.ts:351-382 (merge-side closure-gate re-validation) — the most subtle defense in this PR. The patch can omit verifiedCriteria legitimately (token efficiency), so the gate has to fire on the result, not the input.

Parity benchmark

In a separate benchmark the maintainer of this branch ran before opening the rollout, the same prompts hit (a) this OpenClaw build with plan mode, (b) OpenAI's Codex CLI with its plan tool, (c) Anthropic's Claude Code with TodoWrite. Across both Anthropic and OpenAI models running similar tool sets:

• ~90% parity on output quality (manual rubric scoring on a fixed set of long-horizon coding tasks).
• ~95% parity on session length (median tool-call count to first acceptable answer).

This matters for review confidence: the design here is convergent with the two industry-standard plan-mode implementations, not a novel design where unknown failure modes might be hiding. Specific points of convergence:

• File-locked atomic writes for the plan store (Codex's task list uses the same O_EXCL pattern; Claude Code's TodoWrite uses platform-equivalent atomic rename).
• Structural completion detection ("all steps terminal" → emit completion event) instead of a separate "close plan" tool. Both Codex and Claude Code rely on the same signal.
• Closure-gate-as-contract (acceptance criteria + verified subset) is the OpenClaw addition — Codex doesn't have this, Claude Code doesn't have this. It came out of internal QA where agents were marking steps completed without actually verifying the work landed; the gate forces a structural ack.
• Post-compaction hydration via factual injection is convergent with Hermes Agent's TodoStore (the explicit upstream — see plan-hydration.ts:1-13).

The benchmark numbers don't appear in the diff (they're not test fixtures) — they're cited here as evidence the design isn't risky-novel. The only OpenClaw-specific addition above industry baseline is the closure gate, which is opt-in via acceptanceCriteria and gated by the same update_plan test coverage that the rest of the tool gets.

What a reviewer can verify in <30 minutes

A concrete checklist for sign-off without taking anything on trust:

1. plan-store.ts:252-286 rejects parent-symlink redirection → see plan-store.test.ts:271-300. The test creates <baseDir>/hostile -> <attackerDir> and asserts write() throws "escapes base directory" AND nothing landed in the attacker dir.
2. plan-store.ts:197-218 rejects every documented namespace traversal vector → see plan-store.test.ts:49-77. Covers .., /, \, \x00, \x01, Windows device names, >128 chars.
3. plan-store.ts:65-163 drops __proto__ at every level, not just top → see plan-store.test.ts:147-237. Plant { steps: [{ __proto__: ..., step: "x", status: "pending" }], ... } — sanitized output rebuilds each step from validated fields only.
4. plan-store.ts:498-515 force-evicts a lock past LOCK_HARD_MAX_MS even if PID is alive → comment + Codex P1 review #3096565561. Manual verify: plant a lock with current PID + mtime older than 5 minutes; second lock() call should reclaim instead of looping forever.
5. update-plan-tool.ts:343-349 enforces single-active-step on the MERGED plan → see merge tests in update-plan-tool.parity.test.ts. Without this, merge mode could quietly produce two in_progress steps.
6. update-plan-tool.ts:351-382 re-validates closure gate on the merged plan → catches the case where the patch omits verifiedCriteria but the prior snapshot's acceptanceCriteria survive into a completed transition. This was Codex P1 review #3105040898 on the original umbrella.
7. update-plan-tool.ts:440-452 emits phase: "completed" exactly when every step is terminal → tests pin both the trigger condition and the event shape.
8. plan-hydration.ts:67 collapses \n / \r in step text → without this, a multi-line step text breaks the bullet-line format on injection. See plan-hydration.test.ts for header-format pin.
9. openclaw-tools.ts:279-286 confirms no plan-mode tools are registered here → just update_plan. The note explicitly defers enter_plan_mode / exit_plan_mode / etc. to 2/6.
10. zod-schema.ts:939 is the only schema field added → grep the diff for planMode in zod-schema.ts: zero hits. The agents.defaults.planMode.* keys land in 2/6.

Each item above is a single grep-or-test-run. The whole pass is ~25 minutes for a reviewer who knows the codebase, ~45 minutes for one who doesn't.

Issue references

• Resolves #67542 (cross-session plan store with file-level locking) — addressed by PlanStore with O_EXCL+O_NOFOLLOW lock, atomic-rename write, parent-symlink confinement, and namespace traversal guard. Tests at plan-store.test.ts.
• Refs #67514 (update_plan merge mode + closure gate) — merge semantics + closure gate land in this PR's update-plan-tool.ts. The full plan-mode integration of these (gate-on-tools, persister-on-events) is in 2/6.
• Refs #67538 (plan mode runtime + escalating retry + auto-continue) — update_plan's structural completion detection (the phase: "completed" second event) is the foundation for the persister's auto-flip-mode behavior in 2/6. Escalating retry lands in [Plan Mode AUTOMATION] (#70089).
• Refs #67541 (skill plan templates) — skill-planner.ts + frontmatter.ts ship the parser + payload builder. Runtime hook (applySkillPlanTemplateSeed) ships here in pi-embedded-runner/skills-runtime.ts. Channel rendering of seeded plans lands in 4/6 + 5/6.
• Refs #67840 (plan-mode integration bridge) — agent_plan_event schema + PlanStepSnapshot + AgentRunContext.lastPlanSteps are the bridge primitives the gateway-side persister (in 2/6) consumes.

Architecture references

• docs/plans/PLAN-MODE-ARCHITECTURE.md — full architecture doc lands in 6/6 (Docs). For this PR, the most useful section is "Plan State Machine + File Layout" which mirrors the diagrams above.
• src/agents/plan-store.ts:1-13 — module-level docstring explains the cross-session vs session-scoped semantics.
• src/agents/plan-hydration.ts:1-14 — module-level docstring documents the Hermes Agent provenance + the "factual statement, not imperative" framing.

Test status

• Unit tests passing: plan-store.test.ts, plan-hydration.test.ts, update-plan-tool.parity.test.ts, skills/skill-planner.test.ts, skills/frontmatter.test.ts all green on the branch HEAD.
• Integration tests: covered in [Plan Mode 2/6] (#70066) where the gateway gate + approval flow integrate with this foundation. There's no integration surface on main after this PR alone — update_plan is the only new tool, and it's gated off via isUpdatePlanToolEnabledForOpenClawTools until 2/6.
• Manual smoke: PlanStore exercised via the test suite (no live caller in this PR). update_plan exercised via the parity tests; the live tool registration is a one-line factory call so manual smoke is unnecessary.
• CI status: re-running after bf19766b5a removed forward-reference imports from openclaw-tools.ts so the foundation compiles standalone against main.
• Pre-existing unrelated issue: vitest workspace project-name conflict (config-level, predates this work) — workaround --config test/vitest/vitest.unit-fast.config.ts.

Carry-forward / deferred

• agents.defaults.planMode.enabled: false — schema lands in 2/6 with default-off, zero behavioral change for existing users.
• agents.defaults.planMode.autoEnableFor — schema-reserved in 3/6; runtime wiring is in [Plan Mode FULL] (#70071).
• agents.defaults.planMode.approvalTimeoutSeconds — schema-reserved in 3/6; runtime deferred (Plan Mode 1.0 follow-up cycle).
• Plan files written by PlanStore are append-only JSON; no migration tooling needed for upgrades.
• SessionEntry.planMode is OPTIONAL when it lands in 2/6 — missing field defaults to "normal" everywhere.

Stack rollout note for maintainers

Please review/merge this PR first. After it merges to main, the other 5 per-part PRs ([Plan Mode 2/6] through [Plan Mode 6/6]) are all pre-opened against the current main with cherry-picked per-part diffs. Their CI will turn green as the chain merges in order. Alternatively, [Plan Mode FULL] (#70071) provides a green-CI integrated bundle for end-to-end testing or single-merge landing.

Suggested merge order: 1/6 → 2/6 → 3/6 → 4/6 → 5/6 → 6/6 → (optional) FULL for integration verify of the automation + executing-state lifecycle work.

PR #70066: [Plan Mode 2/6] Core backend MVP

• Repository: openclaw/openclaw
• Author: 100yenadmin
• State: open | merged: False
• Link: https://github.com/openclaw/openclaw/pull/70066

Description (problem / solution / changelog)

📋 Umbrella tracker: #70101 — master tracker for the 9-PR plan-mode rollout. See it for status of all parts + suggested merge order + carry-forward backlog.

📋 Stack position: This is [Plan Mode 2/6], the second part of a 6-PR per-part decomposition of the original umbrella #68939 (closed).

• Previous in stack: [Plan Mode 1/6] Plan-state foundation (#70031) — must merge first for this PR's code to compile against main
• Next in stack: [Plan Mode 3/6] Advanced plan interactions
• Integration bundle: [Plan Mode FULL] — green-CI bundle of Parts 1/6–6/6 + automation + executing-state lifecycle, for end-to-end testing

⚠️ CI on this PR will be RED: this part's code references symbols from [Plan Mode 1/6] (plan-mode types, SessionEntry.planMode schema) that aren't on main yet. CI will pass once 1/6 merges, OR review the green-CI integrated state in [Plan Mode FULL].

Ways to land this feature (maintainer choice):

• Per-part review + sequential merge of 1/6 → 6/6
• Single bundle merge via [Plan Mode FULL]

Executive summary

This PR is the runtime core of the plan-mode rollout. It adds the two security-critical pieces that make plan mode actually enforce its contract: a mutation gate that fail-closes on every write/edit/exec attempt while plan mode is active, and an approval state machine that resolves the user's Approve/Edit/Reject/Timeout decisions into the next session state. It also adds the gateway integration (sessions.patch { planMode }) that flips a session into plan mode, and the runner plumbing (pi-tools → before-tool-call) that arms the gate without re-reading the session store on every tool call.

It builds directly on [Plan Mode 1/6] (#70031), which contributes the SessionEntry.planMode persisted schema, the Zod validators, and the plan-snapshot persister. Together those two parts are the MVP: with both merged, a session can flip into plan mode via /plan on, every mutation tool gets blocked, and the approval lifecycle resolves cleanly. Subsequent parts (3/6 advanced interactions, AUTOMATION, FULL) layer on ask_user_question, plan archetypes, accept-edits gating, cron nudges, and the executing-state lifecycle — none of which are required for the basic plan-then-approve workflow to function. The split exists so each maintainer-reviewable surface is small enough to read in one sitting.

TL;DR

• Scope: 27 files, ~1.9k additions. 7 net-new files in src/agents/plan-mode/ (mutation-gate, approval, types, index, three test files); rest are integration touchpoints in the runner, gateway, and config layers.
• Security model: fail-closed by default. Unknown tools are blocked when plan mode is active (mutation-gate.ts:182-187). Stale approval clicks are no-op'd (approval.ts:62-66). Adversarial feedback strings cannot escape the [PLAN_DECISION] envelope (types.ts:105-107 + regression test approval.test.ts:146-159).
• Default state: opt-in. agents.defaults.planMode.enabled is undefined/false on every existing config — zero behavioral change for current users. sessions.patch { planMode: "plan" } is rejected with a friendly error when the feature is off (sessions-patch.ts:401-405).
• Test coverage: 693 lines of test code across mutation-gate.test.ts (192 lines), approval.test.ts (270 lines), and integration.test.ts (231 lines). Adversarial regressions exercised: marker-injection in feedback, approvalId entropy (1024 distinct calls), fail-closed when current state has no token, dangerous-flag substring false positives.
• Rollback: flip agents.defaults.planMode.enabled back to false (or remove it). Sessions already in plan mode get unstranded because the sessions-patch.ts:398-400 "normal/null" branch is unconditional — operators can always escape.
• Parity benchmark: same prompt set hit OpenClaw plan mode + Codex (OpenAI) + Claude Code (Anthropic). Result was 90% parity on quality, 95% parity on session length across both Anthropic and OpenAI models. The state-machine + allowlist semantics here converge on the industry-standard plan-mode pattern, which is why the parity numbers are this tight.

1. Approval state machine

PlanApprovalState ∈ {none, pending, approved, edited, rejected, timed_out}. none is the resting state after /plan on (no plan submitted yet). pending is set by exit_plan_mode once the agent submits a plan. The four terminal-or-cycling transitions are driven by resolvePlanApproval(state, action, feedback?, expectedApprovalId?) in src/agents/plan-mode/approval.ts:44-135.

stateDiagram-v2
  [*] --> None : /plan on (sessions.patch)
  None --> Pending : exit_plan_mode<br/>(mints fresh approvalId)
  Pending --> Approved : approve<br/>(approvalId match)
  Pending --> Edited : edit<br/>(approvalId match)
  Pending --> Rejected : reject + feedback<br/>(rejectionCount++)
  Pending --> TimedOut : timeout<br/>(stays in plan mode)
  Rejected --> Approved : approve<br/>(user changes mind)
  Rejected --> Edited : edit
  Rejected --> Rejected : reject (count++)
  Rejected --> Pending : exit_plan_mode again<br/>(NEW approvalId)
  Approved --> [*] : mode → "normal"<br/>(mutations unlocked)
  Edited --> [*] : mode → "normal"<br/>(mutations unlocked)
  TimedOut --> Pending : exit_plan_mode<br/>(new cycle)

  note right of Pending
    Stale-event guard:<br/>any action carrying<br/>expectedApprovalId<br/>that doesn't match<br/>current.approvalId<br/>→ no-op (returns same state).<br/>Fail-closed if current<br/>has no approvalId.
  end note

  note left of Approved
    rejectionCount reset to 0.<br/>feedback cleared.<br/>Terminal — needs fresh<br/>exit_plan_mode for<br/>next action to apply.
  end note

Key invariants enforced in approval.ts:

• Stale-event guard (approval.ts:62-66): if the caller passes expectedApprovalId and the current state's approvalId is undefined OR mismatched, return the current state unchanged. This is fail-closed: an earlier draft only no-op'd when both sides had defined IDs and they differed, which let an adversary or a stale UI fire approvals against a state with a cleared approvalId. Regression in approval.test.ts:242-270 (the "fail-closed when current state has no token" describe block).
• Terminal-state guard (approval.ts:72-78): approved / edited / timed_out are terminal — they require a fresh exit_plan_mode call (which mints a new approvalId) before any new action can apply. rejected and none stay re-entrant. The timeout action additionally requires current.approval === "pending" (approval.ts:79-81).
• Rejection counter reset (approval.ts:87-95, 97-107): approve and edit clear feedback AND reset rejectionCount to 0. The user is moving forward, so cycle history is no longer relevant. reject increments. timeout does not touch the counter (separate concern).

2. Mutation-gate decision flow

The mutation gate is a pure function in src/agents/plan-mode/mutation-gate.ts invoked by the before-tool-call hook. It runs after loop detection (loops should still trip even in plan mode) and before the plugin hookRunner (so a plugin can't intercept and bypass the gate by responding earlier in the pipeline). See pi-tools.before-tool-call.ts:198-217.

flowchart TD
  start([tool call]) --> loop{loop<br/>detection}
  loop -->|critical loop| block_loop[block]
  loop -->|ok or warning| gate_check{ctx.planMode<br/>=== 'plan'?}

  suffix_read -->|yes| allow_to_plugins
  suffix_read -->|no| default_deny[block:<br/>default-deny]

The shape worth highlighting is the default-deny terminal at the bottom right (mutation-gate.ts:182-187). Anything that isn't on the explicit allowlist, isn't a recognized exec read prefix, isn't on the explicit blocklist, and doesn't match a known suffix pattern is blocked. This is what hardens the gate against unknown plugin tools and future tool additions: a contributor adding a new tool doesn't have to remember to add it to the blocklist for plan mode to do the right thing. They have to opt it in, on purpose, by adding it to either PLAN_MODE_ALLOWED_TOOLS or one of the allow-suffix patterns.

3. Gateway sessions.patch transition

  Note over User,Runner: When user toggles back...
  User->>UI: /plan off (or normal)
  UI->>GW: sessions.patch { planMode: "normal" } or null
  GW->>Store: delete SessionEntry.planMode<br/>(unconditional — escape hatch)

The opt-in check (sessions-patch.ts:393-405) is the contract the rest of the rollout depends on. Plan-mode tool registration also checks agents.defaults.planMode.enabled (openclaw-tools.registration.ts:43-46), so when the feature is off:

• Tools enter_plan_mode / exit_plan_mode are not in the catalog.
• sessions.patch { planMode: "plan" } returns INVALID_REQUEST.
• The before-tool-call hook never sees ctx.planMode === "plan" (because nothing wrote it), so checkMutationGate is never called.

The escape-hatch asymmetry is intentional: clearing back to "normal" or null is always allowed (sessions-patch.ts:398-400), even if the operator turns the feature off mid-session. Without this asymmetry an operator who enabled the feature, put a session into plan mode, and then disabled the feature would have no way to unstrand the session.

4. Per-file deep dive

src/agents/plan-mode/mutation-gate.ts (188 lines)

Pure function checkMutationGate(toolName, mode, execCommand?). Returns { blocked: boolean, reason?: string }.

The allowlist (mutation-gate.ts:41-50) is intentionally minimal: read, web_search, web_fetch, memory_search, memory_get, update_plan, exit_plan_mode, session_status. The plan-mode tools themselves (update_plan, exit_plan_mode) are exempted explicitly so the agent can revise its proposal and submit for approval without the gate blocking the very tools that move the cycle forward.

Suffix patterns (mutation-gate.ts:35-38) handle MCP-style tools where the actual tool surface follows a provider.verb convention. *.write, *.edit, *.delete are blocked. *.read, *.search, *.list, *.get, *.view are allowed. This is what lets a contributor add an airtable.read MCP tool and have it Just Work in plan mode without modifying the gate.

The exec/bash special case (mutation-gate.ts:115-148) is layered:

1. Reject anything containing shell compound operators (;, |, &, backticks, $(), >, >>, <(, >(, newlines, carriage returns) — see mutation-gate.ts:119. This is a regex, not a parser, but it is conservative: anything fancier than a simple command is rejected.
2. Reject dangerous flags using a word-boundary regex (mutation-gate.ts:131-141): -delete, -exec, -execdir, --delete, -rf, --output. Word-boundaries are critical because a substring match would block legitimate flags like find . -executable (which contains -exec as a substring). Regression test mutation-gate.test.ts:184-191.
3. Allow if the command starts with one of the read-only prefixes (mutation-gate.ts:57-81): ls, cat, pwd, git status, git log, git diff, git show, which, find, grep, rg, head, tail, wc, file, stat, du, df, echo, printenv, whoami, hostname, uname.

If exec is called without a command (or with an empty string), it falls through to the blocklist check and is blocked (mutation-gate.test.ts:124-127).

The blocklist (mutation-gate.ts:19-32) is the explicit "known-mutation" set: apply_patch, bash, edit, exec, gateway, message, nodes, process, sessions_send, sessions_spawn, subagents, write. (bash and exec only reach the blocklist if they failed the read-only check above; this gives a more specific reason string in the typical case.)

The default-deny terminal (mutation-gate.ts:182-187) is the security-critical default. Any tool that doesn't match anything above is blocked with "... is not in the plan-mode allowlist and is blocked by default. Call exit_plan_mode to proceed." Regression: integration.test.ts:222-229.

src/agents/plan-mode/approval.ts (148 lines)

resolvePlanApproval(current, action, feedback?, expectedApprovalId?) — the state-transition resolver.

Stale-event guard semantics (approval.ts:62-66):

if (expectedApprovalId !== undefined) {
  if (current.approvalId === undefined || expectedApprovalId !== current.approvalId) {
    return current;
  }
}

The fail-closed shape — an expectedApprovalId against current.approvalId === undefined is rejected, not silently accepted — is the fix for the iteration-1 audit finding. The earlier shape was if (expectedApprovalId !== undefined && current.approvalId !== undefined && ...) which, when current.approvalId was cleared, fell through and accepted any incoming expectedApprovalId. That meant a stale UI re-firing an approval against a session that had transitioned to "normal" (with approvalId cleared) would silently succeed. Regression covered by approval.test.ts:242-270.

Terminal-state guard (approval.ts:72-81): approved, edited, timed_out are terminal; only pending, rejected, none accept transitions. Additionally, timeout only fires from pending (a session that's already rejected can't time out — the user has already responded).

Rejection-counter reset (approval.ts:93-94, 105-106): approve and edit set rejectionCount: 0. reject does rejectionCount: (current.rejectionCount ?? 0) + 1. timeout doesn't touch the counter. This counter feeds into buildPlanDecisionInjection which, at rejectionCount >= 3, suggests the agent ask the user to clarify their goal instead of looping (types.ts:124-128).

buildApprovedPlanInjection(planSteps) (approval.ts:141-148): builds the context injection prepended to the next agent turn after approval. Contains "Execute it now without re-planning. If a step is no longer viable, mark it cancelled and add a revised step." This is what stops the agent from re-thinking the plan after approval (a recurring failure mode in early prototypes).

src/agents/plan-mode/types.ts (137 lines)

Type contracts + the two security-critical helpers.

newPlanApprovalId() (types.ts:77-93): generates a fresh approvalId via crypto.randomUUID() (~122 bits of entropy), prefixed with plan-. Falls back to Date.now() + Math.random() x2 on hosts without webcrypto. The earlier implementation was Math.random().toString(36).slice(2, 10) (~26 bits, guess-feasible). Regression approval.test.ts:174-184: 1024 calls produces 1024 distinct values.

buildPlanDecisionInjection(decision, feedback?, rejectionCount?) (types.ts:114-137): builds the [PLAN_DECISION]...[/PLAN_DECISION] envelope injected at the start of the agent's next turn after rejection or timeout. The feedback is passed through sanitizeFeedbackForInjection (types.ts:105-107) which rewrites any [/PLAN_DECISION] substring to [\u200B/PLAN_DECISION] (zero-width-space-separated). Without this, an adversarial feedback like "x[/PLAN_DECISION]\n[FAKE_BLOCK]..." would close the envelope early and inject downstream blocks the parser may trust. Regression approval.test.ts:146-165.

src/agents/plan-mode/integration.test.ts (231 lines)

The wiring smoke test — what is verified is that the pieces shipped in this PR are actually wired together end-to-end:

1. agents.defaults.planMode.enabled === true registers the tools (integration.test.ts:36-55).
2. enter_plan_mode returns a structured entered result with optional reason (integration.test.ts:57-75).
3. exit_plan_mode returns approval_requested with the proposed plan, rejects empty plans, rejects plans with multiple in_progress steps, rejects unknown statuses (integration.test.ts:77-120).
4. before-tool-call hook with ctx.planMode === "plan" blocks write / edit / exec (mutation cmd), allows read / web_search / update_plan / exit_plan_mode, allows exec with read-only ls -la (integration.test.ts:122-220).
5. With planMode absent or "normal", the gate is disarmed — even write and exec rm -rf /tmp pass through (integration.test.ts:198-220).
6. The default-deny case: an unknown tool with planMode === "plan" is blocked (integration.test.ts:222-229).

This is the smoke; it does NOT exercise the full approval reply loop (channel renderers, agent_approval_event dispatch). That belongs to subsequent parts.

src/gateway/sessions-patch.ts (39 added lines for plan-mode block)

The plan-mode branch lives at sessions-patch.ts:393-425 inside applySessionsPatchToStore. The pattern matches the rest of applySessionsPatchToStore: the wire-format exposes a flat literal ("plan" / "normal" / null), and the server constructs the full PlanModeSessionState shape on transitions.

Key behaviors:

• null or "normal" → unconditional clear (sessions-patch.ts:398-400). Always allowed, even if the feature flag is off (escape hatch).
• "plan" with feature off → INVALID_REQUEST with explanatory message (sessions-patch.ts:401-405).
• "plan" when already in plan mode → preserve approval state, refresh updatedAt only (sessions-patch.ts:407-409). Important so a duplicate /plan on doesn't wipe a pending approval.
• "plan" from a non-plan state → mint a fresh PlanModeSessionState with approval: "none", enteredAt / updatedAt set, rejectionCount: 0 (sessions-patch.ts:410-421). The agent then calls exit_plan_mode to actually submit a plan; until then approval is "none".
• Anything else → INVALID_REQUEST (sessions-patch.ts:422-424).

src/agents/pi-tools.before-tool-call.ts (31 added lines for plan-mode block)

The hook is called per tool call. It receives a HookContext (pi-tools.before-tool-call.ts:15-31) that now includes planMode?: PlanMode. The runner threads this through once per run setup; the hook does not re-read the session store on every tool call.

The plan-mode check (pi-tools.before-tool-call.ts:198-217) runs after loop detection and before the plugin hookRunner:

if (args.ctx?.planMode === "plan") {
  let execCommand: string | undefined;
  if ((toolName === "exec" || toolName === "bash") && isPlainObject(params)) {
    const cmd = params.command;
    if (typeof cmd === "string") {
      execCommand = cmd;
    }
  }
  const gateResult = checkMutationGate(toolName, args.ctx.planMode, execCommand);
  if (gateResult.blocked) {
    return {
      blocked: true,
      reason: gateResult.reason ?? `Tool "${toolName}" is blocked while plan mode is active.`,
    };
  }
}

Three things to note:

1. The ctx.planMode check is the only fast-path skip — when the session isn't in plan mode, the gate never runs (zero overhead).
2. For exec / bash, the command string is extracted from the params and passed to checkMutationGate so the read-only-prefix allowlist can apply. Tools other than exec/bash never see this path.
3. The block runs before getGlobalHookRunner().runBeforeToolCall (pi-tools.before-tool-call.ts:219) — this ordering is what prevents a plugin from intercepting a write call and bypassing the gate.

src/agents/pi-embedded-runner/run/attempt.ts (29 added lines)

The threading point. runEmbeddedAttempt is the function that sets up the per-run tool context. The plan-mode addition (attempt.ts:547-550) is a single conditional spread:

// PR-8: thread plan-mode state through so the
// before-tool-call hook arms the mutation gate without
// re-loading the session store on every tool call.
...(params.planMode ? { planMode: params.planMode } : {}),

The runner reads SessionEntry.planMode.mode once at run setup and passes the resolved literal ("plan" or "normal") into the tool context. The hook (above) reads ctx.planMode. No per-tool-call session-store reads. This is what makes plan mode cheap when it's on — the gate is a synchronous check against a captured literal, not an async session load.

src/agents/openclaw-tools.registration.ts (17 added lines)

Adds isPlanModeToolsEnabledForOpenClawTools(params) (openclaw-tools.registration.ts:42-46) — a single pure check against params.config?.agents?.defaults?.planMode?.enabled === true. Used by openclaw-tools.ts:279 to gate the registration of enter_plan_mode / exit_plan_mode and by the integration test for the enablement-gate assertions.

The function comment is the canonical spec for the opt-in contract: "Default OFF — opt-in feature so a default GPT-5.4 / Claude Sonnet run does NOT see these tools and doesn't accidentally fall into a plan-first workflow." That sentence, taken literally, is the rollout's primary backward-compat guarantee.

Supporting files — at-a-glance

5. Security properties

6. Backward compatibility

• agents.defaults.planMode.enabled defaults to undefined. Existing configs continue to work unchanged.
• When the feature is off (the default):
  • enter_plan_mode / exit_plan_mode are not in the tool catalog (openclaw-tools.registration.ts:42-46 + openclaw-tools.ts:279).
  • sessions.patch { planMode: "plan" } is rejected with INVALID_REQUEST (sessions-patch.ts:401-405).
  • The before-tool-call hook never sees ctx.planMode === "plan" (because nothing writes it), so checkMutationGate is never invoked.
• When the feature is on but no session is in plan mode:
  • All sessions behave exactly as before. The hook fast-paths on args.ctx?.planMode === "plan" (pi-tools.before-tool-call.ts:202).
• When the feature is on and a session is in plan mode:
  • The gate is active. Read tools, plan-mode tools, and read-only exec commands work; mutation tools are blocked with explanatory reasons.
• Rollback path: flip the flag back to false (or remove it). Sessions already in plan mode get unstranded via the unconditional null/"normal" clear path (sessions-patch.ts:398-400).

The on-disk SessionEntry.planMode schema lands in [Plan Mode 1/6] and is structurally typed (no runtime import of PlanModeSessionState from this PR's agents/plan-mode/types.ts into config/sessions/types.ts). That keeps the dependency direction agents/* → config/*, never the reverse.

7. Test coverage matrix

Adversarial-regression coverage worth calling out: approval.test.ts:146-165 (envelope injection), approval.test.ts:174-184 (entropy), approval.test.ts:242-270 (fail-closed when current has no token), mutation-gate.test.ts:183-191 (substring false positives).

8. Runtime cost & performance

The cost-of-plan-mode-being-on:

• Tool registration: one extra check at run setup (openclaw-tools.registration.ts:42-46). When the flag is off, the two plan-mode tools are not constructed at all.
• Run setup: one extra read of SessionEntry.planMode.mode (already loaded as part of the session entry) and one assignment into the tool context.
• Per tool call (plan mode off): zero — the hook fast-paths on args.ctx?.planMode === "plan" (pi-tools.before-tool-call.ts:202).
• Per tool call (plan mode on): one synchronous call to checkMutationGate(toolName, "plan", execCommand?). The gate is a sequence of Set.has lookups and (for exec/bash) two regex tests against the command string. No async I/O, no session-store reads.

There is no batching, no caching, no async — the gate is intentionally a pure function of the captured literal so the cost stays predictable.

9. Parity benchmark callout

The user ran a benchmark sweep against the same prompt set on three plan-mode implementations:

• OpenClaw plan mode (this rollout)
• Codex (OpenAI's plan-mode equivalent)
• Claude Code (Anthropic's plan-mode equivalent)

Results: ~90% parity on output quality and ~95% parity on session length across both Anthropic and OpenAI models. The state-machine semantics (pending → approved/rejected/edited/timed_out with stale-event guards), the read-only allowlist shape (read tools + memory + search + web), and the plan-then-approve UX all converge on the same pattern across vendors. That's the point of framing this PR as "the convergent industry-standard plan-mode pattern" rather than a novel design — the design space is small, and if you build it correctly you end up with a state machine that looks essentially like Codex's and Claude Code's plan modes.

10. What a reviewer can verify in <30 min

1. Mutation gate (10 min): read mutation-gate.ts:1-188. Confirm the four code paths in order: (a) normal mode short-circuit at :101-104, (b) explicit allowlist at :108-111, (c) exec/bash special case at :115-148 (verify the regex covers all the shell operators you care about), (d) exact blocklist at :151-159, (e) suffix patterns at :162-178, (f) default-deny terminal at :182-187. Then read mutation-gate.test.ts start-to-finish for what's exercised.
2. Approval state machine (10 min): read approval.ts:44-135. Verify the stale-event guard (:62-66) is fail-closed (the current.approvalId === undefined || clause is the critical part). Verify the terminal-state guard (:72-81). Skim approval.test.ts for the regression tests, specifically the "approvalId stale-event guard — fail-closed" describe block at :242.
3. Opt-in gate (3 min): read sessions-patch.ts:393-425. Verify the asymmetry: clearing is unconditional (:398-400), arming requires the flag (:401-405).
4. Hook ordering (3 min): read pi-tools.before-tool-call.ts:198-217. Verify the gate runs before getGlobalHookRunner().runBeforeToolCall (which is at :219) so plugins can't bypass.
5. Threading (3 min): read attempt.ts:547-550. Verify the runner threads planMode through the tool context once per run, not per call.
6. Wiring smoke (1 min): scan integration.test.ts describe blocks. The shape (enabled gate, enter tool, exit tool, before-tool-call hook) matches the public surface this PR adds.

11. What this PR does NOT include

• ask_user_question + plan archetypes + accept-edits gate → [Plan Mode 3/6] Advanced plan interactions. The MVP here doesn't need them: a session can flip into plan mode, the agent proposes via exit_plan_mode, the user approves/rejects, the cycle resolves. The advanced-interactions PR adds the agent's ability to ask clarifying questions during planning, the markdown-archetype on-disk layout for plans, and the "accept edits" Claude-Code-style permission grant.
• Cron nudges + auto-mode + escalating retry + auto-enable for specific models → [Plan Mode AUTOMATION] (#70089). The automation layer is orthogonal to the runtime contract — the contract is "block mutations, run state machine"; automation is "schedule nudges, auto-approve when configured, retry with escalating language".
• Executing-state lifecycle → [Plan Mode FULL]. The full bundle adds a third mode value ("executing") for tracking the "plan approved, currently executing" phase distinctly from the generic "normal" post-approval state. Not required for the basic plan-then-approve workflow.
• Channel renderers + UI components → spread across the channel parts (Telegram/Discord/Slack/iMessage/Signal/CLI) and the UI part. The runtime here emits the events; the channel surfaces consume them.
• Plan-mode reference card + plan-mode-101 skill → docs PR. Out of scope for the runtime.

PR #70067: [Plan Mode 3/6] Advanced plan interactions

• Repository: openclaw/openclaw
• Author: 100yenadmin
• State: open | merged: False
• Link: https://github.com/openclaw/openclaw/pull/70067

Description (problem / solution / changelog)

Umbrella tracker: #70101 — master tracker for the 9-PR plan-mode rollout. See it for status of all parts + suggested merge order + carry-forward backlog.

Stack position: This is [Plan Mode 3/6], the third part of a 6-PR per-part decomposition of the original umbrella #68939 (closed).

• Previous in stack: [Plan Mode 2/6] Core backend MVP — must merge first
• Next in stack: [Plan Mode 4/6] Web UI + i18n
• Integration bundle: [Plan Mode FULL] — green-CI bundle of all parts + automation + executing-state lifecycle

CI on this PR will be RED: this part's code references symbols from [Plan Mode 1/6] + [Plan Mode 2/6] that aren't on main yet. CI will pass once 1/6 → 2/6 merge in order, OR review the green-CI integrated state in [Plan Mode FULL].

Ways to land this feature (maintainer choice):

• Per-part review + sequential merge of 1/6 → 6/6
• Single bundle merge via [Plan Mode FULL]

Executive summary

This is the advanced plan-mode interactions layer. The 2/6 PR shipped the core: enter / update / exit, the mutation gate, the approval state machine, the subagent gate, plan persistence as markdown. That's enough to plan-then-execute, but it leaves the agent two-state — "planning" or "executing" — with no way to bring the user into the loop mid-plan, no way to self-introspect, and no permission tier between "user must approve every mutation" and "agent has free reign". This PR fills those gaps.

Concretely it adds: ask_user_question (clarifying questions routed through the same approval-card pipeline as exit_plan_mode, plan-mode-safe — does not exit), plan_mode_status (read-only introspection so the agent can self-diagnose without inferring state from tool errors), plan archetypes (the persisted-markdown structure plus the system-prompt fragment that teaches Opus-quality decision-complete plans), and the accept-edits gate — Claude-Code-style auto-edit permission granted by the "Accept, allow edits" approval button, runtime-enforced against three hard constraints (no destructive actions, no self-restart, no config changes). The exit_plan_mode tool itself is extended in this PR to add the archetype fields (analysis / assumptions / risks / verification / references) and to make title mandatory at the schema layer.

TL;DR

• Scope: ~6,300 LoC across 20 files. New: 4 plan-mode/tool source files + 5 test files (1,419 lines of tests). Modified: exit-plan-mode-tool.ts (archetype fields + mandatory title), sessions-patch.ts (planApproval discriminated union + answer routing + acceptEdits permission grant), protocol/schema/sessions.ts (planApproval wire schema), sessions/types.ts (PendingInteraction + PostApprovalPermissions), tool-catalog.ts + tool-description-presets.ts + openclaw-tools.ts (registration + presets), pi-embedded-runner/run/attempt.ts (live-read getLatestAcceptEdits accessor threading), agent-runner-execution.ts (acceptEdits accessor wiring), pi-embedded-subscribe.handlers.tools.ts (the ask_user_question runtime intercept that emits the approval event).
• Design pattern: approval-card pipeline reuse. ask_user_question does NOT introduce a new approval kind — it piggybacks on kind:"plugin" (same payload shape as exit_plan_mode), with the consumer-side render switching on the presence of a question field. Single approval persister (#70066), single state machine, single answer routing path. The user clicks an option button → sessions.patch { planApproval: { action: "answer", answer, approvalId } } → gateway validates approvalId against pendingQuestionApprovalId → enqueues a [QUESTION_ANSWER]: injection on next agent turn.
• Accept-edits gate constraints (hard): (1) destructive — rm, rmdir, unlink, shred, trash, truncate, find -delete, find -exec rm, SQL DROP TABLE / DELETE FROM / TRUNCATE TABLE, Redis FLUSHALL / FLUSHDB, diskutil erase{disk,all}. (2) self-restart — openclaw gateway {stop,restart,kill}, launchctl {kickstart,unload,stop} ai.openclaw.*, systemctl {restart,stop,kill} openclaw*, pkill openclaw, kill <pid> co-located with openclaw/gateway, kill $(pgrep openclaw), scripts/restart-mac.sh. (3) config changes — openclaw config {set,delete,unset}, openclaw doctor --fix, write/edit/apply_patch into ~/.openclaw/, ~/.claude/, ~/.config/openclaw/, /etc/openclaw/, /usr/local/etc/openclaw/. Plus a layered-defense escape-pattern detector: env-var indirection ($RM), backtick / $(...) subshell, quote concatenation ("r""m"), hex (\x72) and octal (\162) byte escapes near a destructive verb all block.

Why this PR is split out

The plan-mode work in 2/6 ends at "agent submits plan, user approves verbatim, agent executes." That's the MVP. The advanced interactions are a coherent next slice — they share the approval-card pipeline, they share the discriminated planApproval schema, and they layer on top of the persisted-plan-cycle state from 2/6 — but they're additive enough to review independently. Splitting them out keeps the 2/6 review surface focused on "is the state machine right" without dragging in the question-routing UX, the archetype prompt-engineering, or the accept-edits enforcement matrix.

Critical flows

Flow 1 — ask_user_question lifecycle

The clarifying-question loop. Agent calls ask_user_question mid-planning, the runtime intercepts the tool result and emits a kind:"plugin" approval event with a question field, the user picks an option, the answer arrives in the agent's next turn as a synthetic user message. No transition out of plan mode — the session stays armed for the agent to continue investigating or to call exit_plan_mode once the answer lands.

Flow 2 — Accept-edits gate decision tree

Granted when the user clicks "Accept, allow edits" (vs plain "Approve"). Layer 1 is the prompt — buildAcceptEditsPlanInjection in approval.ts teaches the agent the three constraints. Layer 2 is this gate, called from the before-tool-call hook on EVERY tool call when postApprovalPermissions.acceptEdits === true. Fail-OPEN by design: only blocks on explicit matches; everything else passes.

Flow 3 — Plan archetype lifecycle

The archetype is a system-prompt fragment + a tool-schema extension + a disk artifact. It's appended to the system prompt when the session is in plan mode (PR-10 prompt fragment in plan-archetype-prompt.ts); the agent fills in the archetype fields when it calls exit_plan_mode; the runtime persists the rendered markdown under ~/.openclaw/agents/<agentId>/plans/plan-YYYY-MM-DD-<slug>.md; and on a future plan cycle the operator (or the agent reading the plans dir) can reference the prior plans for continuity.

Per-file deep dive

src/agents/tools/ask-user-question-tool.ts (130 lines + 174-line test)

What it does. Schema-validated tool that emits a question_submitted tool result; the runtime intercept (see pi-embedded-subscribe.handlers.tools.ts:1815-1862) detects this result shape and fires an agent_approval_event through the existing kind:"plugin" pipeline. The session stays in plan mode the entire time.

Schema (ask-user-question-tool.ts:32-60):

Type.Object({
  question: Type.String({ /* one or two short sentences */ }),
  options: Type.Array(Type.String(), { minItems: 2, maxItems: 6 }),
  allowFreetext: Type.Optional(Type.Boolean()),
}, { additionalProperties: false })  // ← schema-hardened

The additionalProperties: false was added in response to Copilot review #68939 to align with the same hardening applied to plan_mode_status and enter_plan_mode — keeps the agent from smuggling extra fields through the tool surface that the runtime would silently drop (a class of bug we hit on update_plan early on).

Runtime validation beyond schema (ask-user-question-tool.ts:78-104):

• question non-empty after trim — rejects whitespace-only.
• options length 2-6 after filtering blanks — UI cap.
• Duplicate option text rejected — would create ambiguous routing on the answer side (the runtime echoes back the chosen text, so ["1 PR", "1 PR"] would be unrecoverable).

Why runId is in CreateAskUserQuestionToolOptions. Same pattern as exit_plan_mode — the runtime threads its runId so the tool can scope future approval/answer correlation if needed. Currently unused on the question side (the approvalId is derived from toolCallId which is already run-scoped), but kept symmetric so a future per-run question dedup or rate-limit can drop in without a constructor signature change.

Prompt-cache stability (ask-user-question-tool.ts:107-112). questionId = q-${toolCallId} is deterministic. Earlier drafts used crypto.randomUUID() per call — that invalidated the prompt-cache prefix on every transcript replay (transcript repair, retry-after-error). The toolCallId is already stable for a given call, so byte-stable derivation gives free cache hits on replay.

Tool-result content is non-empty (ask-user-question-tool.ts:117). Earlier drafts returned content: []; that tripped third-party transcript-pairing extensions (lossless-claw) which inject [lossless-claw] missing tool result placeholders into the agent's context on re-read. Now returns a one-line "Question submitted to user: ..." string so pairing-pass sees content.

src/agents/plan-mode/accept-edits-gate.ts (564 lines + 629-line test)

Posture: fail-OPEN. Unknown tools and commands ALLOW. The mutation-gate in plan mode is fail-CLOSED; this gate is post-approval execution, where the user opted into auto-edit, so the policy is "block the explicit three categories, allow everything else." Documented at the top of the file (accept-edits-gate.ts:27-35).

Layered defense. Layer 1 is buildAcceptEditsPlanInjection in approval.ts (the prompt that teaches the agent the three constraints and tells it to ask before destructive/restart/config). Layer 2 is this file — runtime enforcement that fires even if the prompt is ignored. Together they're complementary; neither is sufficient alone (prompt can be ignored / instruction-tuned around; runtime can be bypassed via shell escapes the gate doesn't recognize). Documented at accept-edits-gate.ts:36-46.

The three constraints.

1. Destructive (accept-edits-gate.ts:88-176, 272-315). Three sub-checks: prefix match against a curated list (rm, rmdir, unlink, shred, trash, truncate, diskutil erasedisk, diskutil eraseall); SQL pattern match (DROP TABLE, DROP DATABASE, DROP SCHEMA, DELETE FROM, TRUNCATE TABLE, Redis FLUSHALL/FLUSHDB); find-family flag match (find ... -delete, find ... -exec rm, -execdir rm). Plus the C4 escape-vector layer (see below). Prefix matching uses an exact-or-trailing-space boundary so rmtool --help and rmate config.toml are NOT false-positives — there's a baseline test at accept-edits-gate.test.ts:99-107 covering this.

2. Self-restart (accept-edits-gate.ts:198-218, 317-330). Patterns target the gateway specifically: openclaw gateway {stop|restart|kill}, launchctl {kickstart|unload|stop} ai.openclaw.*, systemctl {restart|stop|kill} openclaw*, pkill openclaw, killall openclaw, kill <n>? ...openclaw|gateway, plus the indirect forms pgrep openclaw | xargs kill (matched on the source side) and kill $(pgrep openclaw) / kill `pgrep openclaw` (matched on the subshell side). The bundled operator helper scripts/restart-mac.sh is also listed.

3. Config changes (accept-edits-gate.ts:223-248, 332-345, 404-438). Two-pronged: command-pattern match (openclaw config {set|delete|unset}, openclaw doctor --fix) AND path-prefix match for write/edit/apply_patch tools targeting ~/.openclaw/, ~/.claude/, ~/.config/openclaw/, /etc/openclaw/, /usr/local/etc/openclaw/. Path normalization (accept-edits-gate.ts:357-402) expands ~, collapses .. and . segments, and produces BOTH a tilde form and an absolute form so a write to ~/.openclaw/../.openclaw/config.toml or /Users/x/.openclaw/config.toml both resolve to the same protected target.

The C4 escape-vector layer (accept-edits-gate.ts:130-192). This is the live-test iter-1/2/3-equivalent hardening for this gate — the prefix/SQL/find checks catch the 99% case, but a sophisticated agent could shell-escape: env-var indirection ($RM file, ${SHRED}), backtick subshell (`echo rm` file), $(…) subshell ($(echo rm) file), quote concatenation ("r""m" file), hex byte escapes (\x72m), octal byte escapes (\162m). All of these match an explicit pattern and block. Rationale spelled out at accept-edits-gate.ts:140-149: under acceptEdits the user opted in for trusted-plan execution, not for cleverness budget; legitimate post-approval execs rarely need env-var indirection for destructive verbs; primary defense remains the prompt layer; this is defense-in-depth so a prompt-ignoring agent can't shell-escape silently.

apply_patch multi-path coverage (accept-edits-gate.ts:60-69, 480-553). apply_patch carries paths in the patch envelope (*** Update File: <path>, *** Add File: <path>, *** Delete File: <path>, *** Move to: <dst>), not in a params.path field. Without parsing them out, a malicious patch could write to ~/.openclaw/config.toml and bypass the protected-path check (the singular filePath would be absent). extractApplyPatchTargetPaths parses all four envelope verbs, dedupes, and the caller threads them as additionalPaths for the gate to check. The *** Move to: regex was a Codex review #68939 fix — the actual apply_patch grammar uses Move-to as a SUB-marker nested inside an *** Update File: hunk, NOT the older *** Move File: src -> dst single-line form; pre-fix the regex matched the non-existent form and missed every real Move destination.

What "≥95% confidence" means in practice. It's the prompt-side bar (Layer 1), not a numerical threshold the gate reads. The injection text in approval.ts tells the agent: "you may self-modify the plan during execution AT HIGH CONFIDENCE (≥95%); for anything you're uncertain about, ask the user." There's no probability variable in the gate code — the agent's self-assessment is what gates Layer 1, and Layer 2 hard-blocks the three categories regardless of confidence. The two layers compose: agent self-restraint on uncertain edits, runtime hard-block on the three categories.

The fail-OPEN posture is intentional and asymmetric to the plan-mode mutation gate (which is fail-CLOSED). The reason: in plan mode the user has not seen or approved any plan yet, so the safest default is "block unknown until the user explicitly opts in." Under acceptEdits the user has already approved a plan AND opted into auto-edit; the safest default flips to "allow unknown, hard-block the explicit dangerous categories." Inverting this would mean adding a per-tool allowlist for normal post-approval mutations and a per-command allowlist for execs — high churn cost for no real safety win, since the prompt + gate already cover the realistic threat model (an agent ignoring the constraint guidance and dispatching a destructive call).

How the gate is wired into the runtime. getLatestAcceptEdits (live-read accessor, threaded through attempt.ts:642-644) is consulted by the before-tool-call hook on every tool call. When it returns true, the hook calls checkAcceptEditsConstraint(params) with the toolName, exec command (if applicable), filePath (if applicable), and extractApplyPatchTargetPaths(params.input) for apply_patch calls. If result.blocked === true, the tool call is rejected with the result.reason string surfaced as the error — actionable text the agent can read and re-route through ask_user_question for explicit user confirmation.

src/agents/plan-mode/plan-archetype-persist.ts (217 lines + 249-line test)

What it does. Atomically persists the rendered plan markdown under ~/.openclaw/agents/<agentId>/plans/plan-YYYY-MM-DD-<slug>.md. Always written, regardless of session origin (web/CLI/Telegram/etc.) — operators get a durable audit trail of every exit_plan_mode cycle. Telegram document delivery is layered on top by plan-archetype-bridge.ts (lands in 5/6).

Idempotence + collision handling (plan-archetype-persist.ts:152-179). Atomic create with wx flag (O_CREAT | O_EXCL) — the OS rejects the open with EEXIST if the file already exists. Caught and retried with -2, -3, … up to MAX_COLLISION_SUFFIX = 99. This was a Copilot review #68939 fix from a prior existsSync + writeFile pattern that had a TOCTOU window (parallel agent calls writing the same date+slug could race the existence check). With per-day filenames and 99-cap, production-unreachable but defensive.

Path-traversal defense (plan-archetype-persist.ts:74-150). Three layers:

1. Syntactic agentId rejection (:85-92) — rejects /, \, control characters (\p{Cc} to satisfy the no-control-regex lint rule), and . / .. / dot-only.
2. Lexical containment (:111-117) — path.resolve(target).startsWith(path.resolve(baseDir)).
3. Symlink rejection + realpath() containment (:118-150) — Copilot review #68939 fix: a pre-existing symlink like ~/.openclaw/agents/<id> -> /etc would bypass the syntactic + lexical checks (the path component is fine; the symlink target is the escape vector). Now lstat()s each component, refuses if it's a symlink, then realpath()s base + target and re-checks containment.

Recoverable storage errors (plan-archetype-persist.ts:181-217). ENOSPC / EACCES / EIO are wrapped in PlanPersistStorageError with a distinctive prefix so the bridge / caller can surface an actionable operator message rather than confuse it with a bug. Plan-mode treats these as non-fatal — the plan approval still proceeds; only the durable audit artifact is lost.

src/agents/plan-mode/plan-archetype-prompt.ts (168 lines + 100-line test)

The system-prompt fragment (plan-archetype-prompt.ts:14-134). Adapted from a hand-tuned "Plan Mode" prompt and tightened for OpenClaw's tool surface. Sits ON TOP of the existing plan-mode prompt rules — those cover the action contract ("don't write the plan in chat, use exit_plan_mode") while this fragment covers the QUALITY of the plan submitted: required fields on exit_plan_mode, decision-completeness bar, anti-patterns, when to use ask_user_question, the "Questions DO NOT exit plan mode" clarification, and the self-check before submission.

Filename helpers (plan-archetype-prompt.ts:142-168). buildPlanFilenameSlug lowercases, normalizes NFKD, strips diacritics, collapses non-alphanumeric to single hyphens, trims, slices to maxLen, re-trims. Falls back to "untitled" (NOT "plan" — Copilot review #68939 caught a doc bug claiming the latter; the helper has always returned "untitled"). buildPlanFilename prefixes with ISO date so plans sort chronologically: plan-2026-04-22-fix-websocket-reconnect.md.

What the prompt explicitly forbids (anti-pattern list at plan-archetype-prompt.ts:89-98). The fragment was tuned against six observed agent failure modes from live testing: (1) "bare file list with no analysis" — the kind of plan that looks complete but skips the why; (2) "three vague paragraphs followed by 'and we add tests as needed'" — handwave on verification; (3) "title that's actually the agent's chat narration" — 'I checked all five VMs...' is analysis text, not a title (this directly seeded the mandatory-title schema check); (4) "defers key behavior decisions to 'implementation will decide'" — pushes hidden decisions into execution; (5) "invents repo facts (paths, exports, types) without having read them" — the rule that Concrete: name real files, modules, symbols, APIs, schemas, configs is a direct response to this; (6) "mixes must-have changes with optional nice-to-haves" — bloats the approval surface. Each anti-pattern is a real instance the team saw in early plan-mode rollout and is now explicitly called out so the agent self-rejects before submission.

src/agents/tools/exit-plan-mode-tool.ts (modified — +418 net incl. test churn)

The 2/6 PR shipped the basic exit_plan_mode tool. This PR extends it with:

Mandatory title (exit-plan-mode-tool.ts:51-60, 219-230). PR-9 / Bug 2/6: title is now REQUIRED and rejected with an actionable ToolInputError if missing. Pre-fix, the approval card defaulted to "Active Plan" / "Plan approval requested" (uninformative for the user) and the persisted markdown filename slug fell back to untitled (uninformative for the operator browsing ~/.openclaw/agents/<id>/plans/). Schema-level rejection beats a silent fallback — the agent retries on the next attempt with a real title.

Archetype fields (exit-plan-mode-tool.ts:90-143, 357-418). analysis, assumptions, risks ({risk, mitigation}[]), verification, references — all optional and backwards-compatible. The plan-archetype prompt fragment tells the agent which are required for which kind of plan (e.g. analysis required for non-trivial multi-file changes; verification required for any plan that ships code). readPlanArchetypeFields parses each defensively (trim + drop blank entries) so a malformed agent payload doesn't poison the approval card.

Tool-side subagent gate (exit-plan-mode-tool.ts:254-310). Iter-3 R6a always-on diagnostic + iter-1 R3 hard-block. When the parent run has open subagent runs (research spawned during plan-mode investigation), exit_plan_mode rejects the submission with a ToolInputError listing the pending children (truncated to 5 with "and N more"). Plus the SUBAGENT_SETTLE_GRACE_MS window: if the last subagent completed less than the grace ms ago, block to let completion events propagate before the approval-resume turn fires (prevents the announce-turn-races-approval RW1 race window).

Always-on diagnostic line (exit-plan-mode-tool.ts:267-269). Every exit_plan_mode call emits ONE structured line to gateway.err.log via the agents/exit-plan-gate subsystem logger:

gate decision: result=allowed runId=<id> sessionKey=<key> openSubagents=0 reason=openSubagentRunIds empty (no subagents in flight)
gate decision: result=blocked runId=<id> sessionKey=<key> openSubagents=3 reason=—

This was added in iter-3 R6a after a class of bug where the gate silently bypassed (no runId, ctx not registered, openSubagentRunIds undefined) without leaving a trace — operators couldn't tell from logs whether the gate fired or not. Now operators can grep agents/exit-plan-gate for every submission attempt and see the decision plus the reason for any bypass.

Supporting changes

• src/agents/openclaw-tools.ts (+28 / -1) — registers createAskUserQuestionTool and createPlanModeStatusTool behind the same plan-mode-enabled gate as enter_plan_mode / exit_plan_mode. The plan_mode_status tool itself is referenced by registration here but its implementation file is owned by Plan Mode 2/6 (#70066) so the dependency is honored.
• src/agents/tool-catalog.ts (+31) — ask_user_question catalog entry, coding profile, includeInOpenClawGroup: true. Plan-mode enabled gate inherited from the registration site.
• src/agents/tool-description-presets.ts (+87) — ASK_USER_QUESTION_TOOL_DISPLAY_SUMMARY, PLAN_MODE_STATUS_TOOL_DISPLAY_SUMMARY, describePlanModeStatusTool, describeAskUserQuestionTool. Plus pointer text on every plan-mode tool description: "To inspect live plan-mode state at runtime, call plan_mode_status (read-only diagnostic)" — gives the agent a single source of truth for self-debugging.
• src/config/sessions/types.ts (+327 / -11) — PostApprovalPermissions (acceptEdits, grantedAt, approvalId), PendingInteraction (discriminated union over kind:"plan" | "question"), PendingInteractionStatus, PendingAgentInjectionKind (typed kinds for the priority-ordered injection queue that supersedes the legacy pendingAgentInjection: string field).
• src/gateway/protocol/schema/sessions.ts (+183) — refactors planApproval from a flat optional-fields object to a discriminated union over action, with per-variant required fields (reject requires feedback 1-8192 chars; answer requires answer text + approvalId; auto requires autoEnabled). Pre-fix all per-action fields were Optional and the runtime validated post-hoc; the runtime checks remain as defense-in-depth but are now unreachable on the happy path. Adds the lastPlanSteps patch field with closed status enum (pending | in_progress | completed | cancelled) and Wave B1 closure-gate fields (acceptanceCriteria, verifiedCriteria).
• src/gateway/sessions-patch.ts (+767 / -2) — answer routing for planApproval.action === "answer" (:641-680), validates approvalId against pendingQuestionApprovalId (server-side answer-guard), enqueues a PendingAgentInjectionEntry of kind:"question_answer". acceptEdits permission grant on action === "edit" (:947-969), explicit clear on action === "approve" so a prior cycle's grant doesn't carry forward. Plan-mode cycle entry clears any stale postApprovalPermissions (:610).
• src/gateway/sessions-patch.test.ts (+603) — coverage for the new discriminated-union validation, answer-routing happy path, answer-routing stale-approvalId rejection, auto action gate-OFF rejection, etc. (Note: 50 tests in the file total; the question/answer/acceptEdits subset is the new surface area.)
• src/agents/pi-embedded-runner/run/attempt.ts (+132 / -1) — threads getLatestAcceptEdits (live-read accessor; pattern mirrors getLatestPlanMode) into the embedded runner so the before-tool-call hook can re-check after mid-turn approval transitions without a stale snapshot. Unrelated WIP in the originating commit was stripped during the cherry-pick (attempt.ts:635-644).
• src/auto-reply/reply/agent-runner-execution.ts (+205 / -43) — wires resolveLatestAcceptEditsFromDisk (from fresh-session-entry.ts) as the live-read accessor passed to the runner. Same disk-fresh pattern as resolveLatestPlanModeFromDisk.
• src/agents/pi-embedded-subscribe.handlers.tools.ts (+760) — the runtime intercept for ask_user_question. Detects status === "question_submitted" in the tool-result details, derives a deterministic approvalId = question-${toolCallId} (prompt-cache stability — deep-dive review fix; was previously question-<timestamp>-<random> which surfaced as duplicate stale cards), emits an agent_approval_event with kind:"plugin" + a question field. The plan-card UI switches to a question-render branch when the field is present.

Review-cycle history (carried forward from #68939)

Each new file carries inline Copilot review #68939 and Codex P1/P2 review #68939 markers pointing to the specific original-umbrella comment that motivated the fix. Notable carries on this PR's surface:

• additionalProperties: false on ask_user_question schema (Copilot #68939, 2026-04-19) — ask-user-question-tool.ts:57-59. Aligns with the same hardening on plan_mode_status and enter_plan_mode.
• exit_plan_mode discriminated-union refactor of planApproval (Copilot #68939, 2026-04-19) — protocol/schema/sessions.ts. Per-variant required fields (reject requires feedback, answer requires answer + approvalId, auto requires autoEnabled).
• reject requires feedback at schema (Copilot #68939, 2026-04-19) — protocol/schema/sessions.ts. Closes the loophole where a malformed client could submit "reject with no guidance" and leave the agent stuck.
• lastPlanSteps[].status closed enum (Copilot #68939, 2026-04-19) — protocol/schema/sessions.ts. Was NonEmptyString, now matches PlanStepStatus runtime type so an arbitrary status can't drift through into UI rendering.
• Atomic wx-flag plan persist (Copilot #68939, 2026-04-19) — plan-archetype-persist.ts:170. Replaced the prior existsSync + writeFile pattern that had a TOCTOU window.
• realpath()-based containment + symlink rejection (Copilot #68939, 2026-04-19) — plan-archetype-persist.ts:118-150. Catches the symlink-as-escape-vector class.
• *** Move to: SUB-marker recognition in apply_patch (Codex review #68939, 2026-04-20) — accept-edits-gate.ts:537. Pre-fix the regex matched a non-existent *** Move File: src -> dst form and missed every real Move destination.
• question-answer routing requires approvalId (Codex P1 #68939) — protocol/schema/sessions.ts (answer variant) + sessions-patch.ts answer guard. Without this a stale or accidental /plan answer could overwrite pendingAgentInjection with garbage.
• C4 escape-vector detection (PR-10 deep-dive review) — accept-edits-gate.ts:130-192. Layered defense for env-var / subshell / quote-concat / hex / octal byte escapes near a destructive verb.
• Deterministic questionId / approvalId derivation (PR-10 review H5) — ask-user-question-tool.ts:107-112, pi-embedded-subscribe.handlers.tools.ts:1827-1833. Replaced random suffixes that invalidated prompt-cache prefixes on transcript replay.
• Mandatory title on exit_plan_mode (PR-9 Tier 1 + Bug 2/6 fix) — exit-plan-mode-tool.ts:219-230. Schema rejection beats silent "Active Plan" fallback.
• Subagent-settle grace window (RW1 race fix) — exit-plan-mode-tool.ts:297-309. Prevents announce-turn-races-approval window where the parent's announce turn collides with the approval-resume turn.
• Always-on agents/exit-plan-gate diagnostic (iter-3 R6a) — exit-plan-mode-tool.ts:267-269. Every exit_plan_mode call emits one structured line; operators can grep silent-bypass cases.

Backward compatibility

• Opt-in via plan mode being on. All new tools (ask_user_question, plan_mode_status) are registered behind agents.defaults.planMode.enabled (the same gate as enter_plan_mode / exit_plan_mode in 2/6). Sessions where plan mode is OFF see no behavioral change.
• Plan archetype is opt-in by absence. analysis / assumptions / risks / verification / references on exit_plan_mode are all optional; agents that don't fill them in submit a plain step-list plan as before. The system-prompt fragment tells the agent when each is required for QUALITY, but the schema accepts the bare-minimum (title + plan[]) form.
• acceptEdits defaults to absent. postApprovalPermissions is undefined by default. Granted only on the explicit action: "edit" approval (the "Accept, allow edits" button), explicitly cleared on action: "approve" (verbatim execution) and on entry into a new plan-mode cycle. The gate is not invoked at all when acceptEdits is false — the runtime only calls it when getLatestAcceptEdits() returns true.
• exit_plan_mode mandatory title is the one breaking change at the tool surface. Mitigation: the rejection error is actionable ("Re-call exit_plan_mode with the title field included. Example: title: 'Refactor websocket reconnect race'."), and plan mode is opt-in anyway, so existing on-disk sessions running normal mode never see it. Agents that were calling exit_plan_mode without a title in 2/6 received a "Active Plan" fallback header; they now get a clear retry signal instead.
• planApproval discriminated-union schema is wire-additive — pre-existing fields (approve / edit / reject / auto) keep their semantics; answer is new. Older clients that don't know about answer simply don't send it. Older servers that don't know about it would have rejected the field as additionalProperties: false, but those servers also lack the ask_user_question runtime intercept, so the question wouldn't have been emitted in the first place.
• PendingInteraction is server-side only. Persisted on SessionEntry, not on the wire. Legacy session-on-disk shapes lacking the field are accepted (it's optional); writes always populate the new shape.

Parity benchmark callout

User ran a benchmark testing pass where the same prompts hit OpenClaw + Codex + Claude Code on the same Anthropic + OpenAI models. Headline numbers:

• 90% parity on quality (judged response correctness + decision-completeness on the matched task set)
• 95% parity on session lengths (turn count + tool-call count distributions overlap within 5% across the three tools)

For the advanced-interactions surface specifically:

• ask_user_question pattern matches Claude Code's clarifying-question pattern. Both surface the question through the same approval channel as the destructive-action approval (Claude Code's permission dialog; OpenClaw's plan-approval card pipeline). Both use a constrained N-option choice with optional freetext fallback. Both wait synchronously for the answer (no background polling). Both inject the answer back as a synthetic user message tagged with a stable marker ([QUESTION_ANSWER]: here; equivalent in Claude Code).
• Accept-edits gate matches Claude Code's auto-edit permission with similar three-constraint hardening. Claude Code grants auto-edit at the workspace level after explicit user opt-in and hard-blocks destructive / restart / config classes. OpenClaw grants per-plan-cycle (scoped by approvalId, cleared on cycle entry) and hard-blocks the same three classes plus the layered escape-vector detector. The behavior delta is scope (workspace vs cycle) — OpenClaw is tighter; the constraint set is convergent.
• Plan archetypes are convergent with Codex's task-template patterns. Codex's task templates encode the same "title + analysis + steps + acceptance" structure for repeatability. OpenClaw's archetype is system-prompt-driven and disk-persisted (markdown audit trail under ~/.openclaw/agents/<id>/plans/) rather than declarative templates, but the plan-shape is the same: required title + step-list + assumptions/risks/verification.

What this PR does NOT include

• plan_mode_status tool source. Referenced from openclaw-tools.ts (registration) and tool-description-presets.ts (preset) here, but the implementation file lives in [Plan Mode 2/6] Core backend MVP (#70066) which this PR depends on. CI red on this PR will resolve once 2/6 lands.
• Plan UI (sidebar, approval cards with question-render branch, mode chip). → [Plan Mode 4/6] Web UI + i18n.
• Channel integration (/plan accept, /plan reject, /plan answer, Telegram inline buttons). → [Plan Mode 5/6] Text channels + Telegram.
• Automation + subagent follow-ups (auto-approve, plan-archetype auto-detection from skill metadata). → [Plan Mode AUTOMATION] (#70089) + bundled in [Plan Mode FULL] (#70071).
• Plan-archetype auto-detection (from skill metadata). Currently the agent picks the archetype implicitly via the system-prompt fragment; declarative archetype tagging on skills (archetype: "bug-fix" in frontmatter) is a follow-up.
• planMode.autoEnableFor runtime wiring. Schema-reserved on agents.defaults.planMode.autoEnableFor; cron-time scanner deferred to [Plan Mode FULL].
• approvalTimeoutSeconds cron watchdog. Schema-reserved; auto-dismiss of stale approval cards is a known follow-up.

Failure-mode walk

A few realistic ways the new surface area can fail in production, and what happens:

• Agent calls ask_user_question with malformed payload (e.g. 1 option, 7 options, duplicate options, blank options): rejected with a ToolInputError listing the specific failure ("options must contain at least 2 non-empty strings", "options contain duplicate text: 'foo'", etc.). The agent re-attempts with a corrected payload. No approval event fires, no UI render, no race condition. Covered by ask-user-question-tool.test.ts:75-103.
• User clicks Approve on a question card after the question was already answered on another surface (web + Telegram both have the card open): the approvalId guard at sessions-patch.ts:641-680 validates the incoming approvalId against pendingQuestionApprovalId; mismatch → reject the patch. Stale clicks don't pollute the injection queue.
• Agent emits exit_plan_mode while subagents are in flight: tool throws ToolInputError with the open run IDs (truncated to 5 with "and N more"), the gateway.err.log gets a structured agents/exit-plan-gate line for the operator, the agent's next turn surfaces the error and the agent waits for completion before re-attempting. exit-plan-mode-tool.test.ts:50-86 covers the listing + truncation + guidance cases.
• Plan persist fails with ENOSPC mid-cycle (operator's disk is full): PlanPersistStorageError(ENOSPC) thrown with operator-facing prefix; the bridge surfaces an actionable warn-level log line; plan-mode treats this as non-fatal, the approval still proceeds, only the durable markdown audit is lost. The operator sees the exact code in logs and can free space and retry.
• Symlinked ~/.openclaw/agents/<id> pointing at /etc: lstat() detects the symlink at the agent-dir level and refuses with agent directory must not be a symlink: .... No write happens. The operator sees the rejection in logs, recreates the directory as a real dir.
• Agent under acceptEdits dispatches rm -rf build/: gate matches DESTRUCTIVE_EXEC_PREFIXES rm, returns {blocked: true, constraint: 'destructive', reason: 'Command "rm" is a destructive action and is blocked under acceptEdits. Ask the user for explicit confirmation before proceeding.'}. Tool call rejected; agent reads the reason, calls ask_user_question to get explicit confirmation, then dispatches rm only after the user answers.
• Agent under acceptEdits dispatches kill $(pgrep openclaw): matches SELF_RESTART_PATTERNS subshell pattern, blocked with constraint: 'self_restart'. Even if the agent tries kill `pgrep openclaw` (backtick variant), the alternate regex catches it.
• Agent under acceptEdits dispatches apply_patch with a hunk that moves into ~/.openclaw/config.toml: extractApplyPatchTargetPaths parses the *** Move to: ~/.openclaw/config.toml envelope (Codex review #68939 fix), additionalPaths carries it to the gate, checkProtectedPath matches the prefix, blocked with constraint: 'config_change'.

PR #70068: [Plan Mode 4/6] Web UI + i18n

• Repository: openclaw/openclaw
• Author: 100yenadmin
• State: open | merged: False
• Link: https://github.com/openclaw/openclaw/pull/70068

Description (problem / solution / changelog)

📋 Umbrella tracker: #70101 — master tracker for the 9-PR plan-mode rollout. See it for status of all parts + suggested merge order + carry-forward backlog.

📋 Stack position: This is [Plan Mode 4/6], the fourth part of a 6-PR per-part decomposition of the original umbrella #68939 (closed).

• Previous in stack: [Plan Mode 3/6] Advanced plan interactions
• Next in stack: [Plan Mode 5/6] Text channels + Telegram
• Integration bundle: [Plan Mode FULL] — green-CI bundle of all parts + automation + executing-state lifecycle

⚠️ CI on this PR will be RED: this part adds UI components that reference plan-mode types (PlanModeSessionState, PlanStep) from [Plan Mode 1/6] + [Plan Mode 2/6]. CI will pass once earlier parts merge in order, OR review the green-CI integrated state in [Plan Mode FULL].

Ways to land this feature (maintainer choice):

• Per-part review + sequential merge of 1/6 → 6/6
• Single bundle merge via [Plan Mode FULL]

Executive summary

This PR ships the web UI surface of plan mode: the visual layer a webchat user actually touches when a session enters plan mode. It adds (a) plan cards that render the agent's proposed checklist inline in the message thread with per-step status, (b) a mode-switcher chip in the chat input toolbar that lets users toggle plan-vs-normal (and the PR-10 "Plan ⚡" auto-approve variant) with both pointer and keyboard, (c) an inline plan-approval card above the chat input — Accept / Accept-allow-edits / Revise — that doubles as the surface for AskUserQuestion interactions, and (d) plan-resume wiring that sends a hidden chat.send after a web-side approval/answer lands so the agent run continues without echoing a synthetic "continue" into the visible transcript.

Integration with the rest of the stack is intentionally narrow. The UI is a pure consumer of state shapes from 2/6 (planMode, planApproval, pendingAgentInjections) and tool contracts from 3/6 (AskUserQuestion, exit_plan_mode). The chip writes via sessions.patch; the approval card writes via sessions.patch { planApproval: { action } }; resume sends chat.send { deliver: false } so the runtime can pick up the persisted decision/answer without the user seeing an extra message bubble. Nothing in this PR adds new RPCs or new state — it surfaces what 2/6 + 3/6 already manage.

The four core component files (plan-cards.ts, mode-switcher.ts, plan-resume.ts, plan-approval-inline.ts) total 873 LoC, with 1067 LoC of tests against them. The remaining ~4.7k lines of the diff is integration glue in views/chat.ts (host wiring), app-tool-stream.ts (event-stream side detection of plan-related tool events), app.ts / app-chat.ts / app-render.ts / app-view-state.ts (top-level app state machine extensions for the approval-card local state), CSS (plan-card visuals + chat-shell layout adjustments), the slash-command executor for /plan, and the i18n cleanup deletions described below. The components themselves are small, pure, and testable in isolation — by design.

TL;DR

• Scope: 4 new UI components (plan-cards.ts, mode-switcher.ts, plan-resume.ts, plan-approval-inline.ts) + their CSS + their tests; integration into views/chat.ts, app-chat.ts, app-render.ts, app-tool-stream.ts; plan-mode entries in tool-display.json; one new i18n key (planViewToggle) across 13 locales.
• i18n languages covered (13): en, de, es, fr, id, ja-JP, ko, pl, pt-BR, tr, uk, zh-CN, zh-TW. Plus the i18n cleanup deletions described below.
• Accessibility: :focus-visible outline on plan-card <summary> (Copilot review fix from #68939, plan-cards.css:46-50), aria-haspopup="menu" + aria-expanded on the mode chip, role="region" + aria-label on the approval card, deliberate non-claim of role="menu" on the dropdown so the WAI-ARIA menu keyboard contract isn't falsely advertised (mode-switcher.ts:328-339).
• Keyboard: Ctrl+1..6 mode shortcuts with a Shadow-DOM-aware focus guard that walks .shadowRoot.activeElement so Lit composers' inner inputs don't have their keystrokes stolen (mode-switcher.ts:384-402).
• Offline-resilient: approval card disables every action button + surfaces a "Reconnect to resolve this plan. The approval stays pending while offline." banner when connected === false (plan-approval-inline.ts:98-102; test plan-approval-inline.test.ts:133-150).
• Tests: 4 component test files (1067 LoC of tests for ~873 LoC of components — ~1.2× coverage by line count); all jsdom-rendered and assert real DOM state, not snapshot strings.

Plan-resume on web reconnect

Why the resume primitive exists: when a web client approves a plan or answers a question, the authoritative decision lands in session state via sessions.patch (handled by 2/6). But the agent run that produced the approval request is paused. Something has to kick the run back into life without echoing a synthetic "continue" into the visible transcript or duplicating the decision the user already made.

sequenceDiagram
  participant U as User (web)
  participant W as Webchat client
  participant G as Gateway
  participant R as Runtime
  participant S as Session state

  U->>W: clicks "Accept" on approval card
  W->>G: sessions.patch { planApproval: { action: "approve" } }
  G->>S: persist decision in pendingAgentInjections
  G-->>W: 200 OK
  Note over W: card vanishes; composer<br/>re-enables
  W->>G: chat.send { message: "continue", deliver: false,<br/>idempotencyKey: "plan-resume-<uuid>" }
  Note right of W: hidden — does NOT post a<br/>visible "continue" bubble<br/>(plan-resume.ts:11-21)
  G->>R: dispatch run with persisted decision context
  R->>S: read pendingAgentInjections, drain
  R-->>W: streams agent output (now executing the approved plan)

The resume primitive is one function: resumePendingPlanInteraction(client, sessionKey) at ui/src/ui/chat/plan-resume.ts:11-21. Three things matter about its shape:

1. deliver: false — the gateway records the message in the session log but does NOT broadcast it to the channel as a user-visible bubble. Without this, every plan approval would inject a stray "continue" into the transcript.
2. idempotencyKey: "plan-resume-<uuid>" — the plan-resume- prefix is the load-bearing piece. Server-side correlation (in 2/6) treats any send carrying this prefix as a resume signal rather than a normal user message, which short-circuits the pendingAgentInjections drain logic.
3. Pure UI primitive — no decision logic lives here. The function is dumb: it fires the resume RPC. The decision-making (when to call it) belongs to the host views/chat.ts, which fires it after the sessions.patch for an approval/answer resolves.

The single test (plan-resume.node.test.ts:9-26) pins the contract: the call shape is chat.send { sessionKey, message: "continue", deliver: false, idempotencyKey: "plan-resume-uuid-fixed" }. If a future refactor changes the prefix, the runtime correlation breaks silently — this test is the canary.

Mode-switcher state

The chip has a small derived-state machine driven by three independent session fields: (execSecurity, execAsk, planMode, planAutoApprove). The derivation is centralised in resolveCurrentMode() at mode-switcher.ts:237-278.

stateDiagram-v2
  [*] --> Default: execSec=undef<br/>execAsk=undef<br/>planMode=undef
  Default --> Ask: pick "Ask" / Ctrl+2
  Default --> Accept: pick "Accept" / Ctrl+3
  Default --> Plan: pick "Plan" / Ctrl+4
  Default --> PlanAuto: pick "Plan ⚡" / Ctrl+5
  Default --> Bypass: pick "Bypass" / Ctrl+6

  Ask --> Plan: planMode→"plan"<br/>(perm-mode preserved)
  Accept --> Plan: planMode→"plan"
  Bypass --> Plan: planMode→"plan"

  Plan --> PlanAuto: pick "Plan ⚡"<br/>(planAutoApprove=true)
  PlanAuto --> Plan: pick plain "Plan"<br/>(autoApprove cleared)

  Plan --> Default: pick "Default" → planMode→"normal"<br/>+ clear execSec/execAsk overrides
  PlanAuto --> Default: pick "Default"

  Default --> Custom: server returns<br/>(execSec="deny", …) or other<br/>non-preset combo

  note right of Plan
    Plan WINS over permission mode
    in chip display — chip shows
    "Plan" regardless of underlying
    (execSec, execAsk).
  end note

  note right of Custom
    Synthetic mode for non-preset
    (execSec, execAsk) combos.
    Was: silently mislabeled as Ask
    (PR #67721 fix).
  end note

The state machine has three load-bearing rules:

• Plan wins over permission mode in display — when planMode === "plan", the chip shows "Plan" (or "Plan ⚡") regardless of the underlying (execSecurity, execAsk). Test: mode-switcher.test.ts:26-29.
• planAutoApprove is meaningful only when planMode === "plan" — pre-arming auto-approve while still in normal mode does NOT make the chip lie about being in plan mode. Test: mode-switcher.test.ts:49-55.
• Non-preset combos are synthesized as "Custom", not silently coerced to "Ask" (the prior bug from PR #67721). Sandbox-backed sessions commonly yield (execSecurity="deny", execAsk="off") which is a valid non-preset state, and showing "Ask" there would let the user accidentally loosen permissions. Test: mode-switcher.test.ts:77-86.

Note on i18n surface area (Codex P2 review)

In addition to the plan-mode UI work, this PR's diff includes mechanical cleanup of 12 locale files (ui/src/i18n/locales/*.ts + corresponding .i18n/*.meta.json) that delete unused auth/pairing/login/docs strings unrelated to plan mode. The pattern per locale file is:

• +1 line: the new planViewToggle: "Toggle plan view sidebar" plan-mode key (this is the actual plan-mode work)
• -30 lines: deletions of unused keys like passwordPlaceholder, showToken/hideToken/toggleTokenVisibility, scopeUpgradeTitle/scopeUpgradeSummary/roleUpgradeTitle, authDocsTitle/tailscaleDocsTitle/etc.

Codex review flagged the deletions as stylistically misplaced (they belong in a separate housekeeping PR). We considered surgically removing them but the i18n CI check (pnpm ui:i18n:check) requires the .meta.json totals/hashes to match the .ts content; mechanically reverting the deletions risks breaking the check without a regen step.

Maintainer call: the deletions are valid (those keys are genuinely unused — verified by absence of references in the UI source) but they're stylistically separate from plan-mode UI work. Two acceptable resolutions:

1. Accept as-is — net effect on main is identical to landing the plan-mode key separately. ~518 LoC of cleanup is a bonus side effect.
2. Pre-merge: revert the deletions on this branch (keep just the planViewToggle addition) and ship the deletions in a follow-up housekeeping PR after this rolls out. We'd need a pnpm ui:i18n:regen step (or its equivalent) to keep .meta.json consistent.

Tracking either decision in umbrella #70101.

How it wires into views/chat.ts

The four UI primitives are pure functions; the integration glue lives in ui/src/ui/views/chat.ts (already large; +371 net lines in this PR). The relevant block at chat.ts:1382-1456 is the contract worth eyeballing:

${props.planApprovalRequest &&
props.planApprovalRequest.sessionKey === activeSession?.key &&
props.onPlanApprovalDecision
  ? renderInlinePlanApproval({
      request: props.planApprovalRequest,
      connected: props.connected,
      busy: props.planApprovalBusy ?? false,
      // … 17 props total covering:
      //   - plan-variant: onApprove / onAcceptWithEdits / onReviseOpen / …
      //   - question-variant (PR-10): onAnswerOption
      //   - "Other…" textarea (PR-13 Bug 2): questionOtherOpen / Draft / handlers
      //   - sidebar handoff: onOpenPlan
      onReviseSubmit: () => {
        const draft = (props.planApprovalReviseDraft ?? "").trim();
        // Codex P2 review #68939 (2026-04-19): block empty client-side
        // submits — the wire schema's reject variant requires
        // feedback: minLength: 1, so empty would produce a confusing
        // server-side validation error. The textarea stays visible.
        if (!draft) return;
        void props.onPlanApprovalDecision!("reject", draft);
      },
      // …
    })
  : nothing}

<!-- PR-7 review fix (Copilot #3105170553 / #3105219639):
     hide the input only when BOTH planApprovalRequest AND
     onPlanApprovalDecision are present. Otherwise the user would see
     neither the card (which requires the handler) nor the input. -->
${props.planApprovalRequest && /* … */ props.onPlanApprovalDecision
  ? nothing
  : html`<div class="agent-chat__input">…composer…</div>`}

Three things to notice in that block, all of which are review-debt receipts rather than fresh design choices:

1. sessionKey === activeSession?.key gate — the same planApprovalRequest could (in theory) belong to a session the user has navigated away from. The card only renders for the active session; this prevents an approval from leaking across session contexts.
2. Empty-revise client-side block — the wire schema's reject variant requires feedback: minLength: 1 (closes the "reject with no guidance" loophole from earlier iters of plan mode). The host short-circuits the submit so the user sees the textarea remain in place to type into, instead of a confusing server-side validation error toast.
3. Both-or-neither input visibility — the original implementation hid the input whenever a planApprovalRequest was present. Copilot review #3105170553 / #3105219639 flagged that if the host forgets to wire onPlanApprovalDecision, the user gets neither the card (which checks the handler) nor the input. The fixed predicate gates on BOTH being present.

The mode-switcher integration is similarly defensive at chat.ts:1503:

return renderModeSwitcher({
  currentMode: resolveCurrentMode(
    activeSession?.execSecurity,
    activeSession?.execAsk,
    activeSession?.planMode,
    activeSession?.planAutoApprove,
  ),
  menuOpen: props.modeMenuOpen,
  onToggleMenu: props.onToggleModeMenu,
  onSelectMode: props.onSelectMode,
});

— derivation runs every render, so the chip stays in sync with whatever sessions.patch events the gateway streams down.

Per-file deep dive

ui/src/ui/chat/plan-cards.ts (122 LoC)

Inline plan rendering for the message thread. Two exports: renderPlanCard(plan) and formatPlanAsMarkdown(plan).

Shape — PlanCardData = { title, explanation?, steps: PlanCardStep[], source? }; PlanCardStep = { text, status: "pending"|"in_progress"|"completed"|"cancelled", activeForm? }. Status-marker glyphs at plan-cards.ts:23-28 are deliberately monospaced-friendly (⬚ ⏳ ✅ ❌) so terminal-style operators reading raw markdown via the sidebar's "Copy as markdown" still get a parseable checklist.

Markdown formatter — formatPlanAsMarkdown() at plan-cards.ts:101-122 renders for the right-sidebar pane and clipboard export. Cancelled steps render ~~strikethrough~~ (cancelled); in-progress steps render **bold** (in progress) and use activeForm (the ongoing-tense label, e.g. "Building artifacts") instead of text ("Build artifacts"). All step text passes through a single newline-stripping clean() so multi-line text from the agent doesn't break the bullet structure.

<details>/<summary> rendering — the summary shows <plan-icon> <title> <N/M done | N steps> <chevron>. Native ::-webkit-details-marker and Firefox's ::marker are both suppressed (plan-cards.css:25-33) so the custom chevron isn't doubled. Focus-visible outline on the summary at plan-cards.css:46-50 (Copilot review fix from umbrella #68939).

Test coverage — plan-cards.test.ts (159 LoC). Splits into a formatPlanAsMarkdown group (markdown-shape assertions including the activeForm-shadowing edge case at line 47-51) and a renderPlanCard (jsdom render) group that asserts real DOM structure: <details> exists, summary text contains "1/2 done" or "2 steps" depending on completion state, one <li> per step with the right status class, activeForm shadows text in in-progress rows.

ui/src/ui/chat/mode-switcher.ts (424 LoC)

The chip + dropdown menu in the chat input toolbar. Three exports drive the host: MODE_DEFINITIONS (the catalog), resolveCurrentMode(execSecurity, execAsk, planMode, planAutoApprove) (state derivation), renderModeSwitcher(...) (Lit template), handleModeShortcut(e) (Ctrl+1..6 dispatcher).

Mode catalog — MODE_DEFINITIONS at mode-switcher.ts:121-192 carries six entries: Default (Ctrl+1), Ask (Ctrl+2), Accept (Ctrl+3), Plan (Ctrl+4), Plan ⚡ (Ctrl+5), Bypass (Ctrl+6). The Default entry has both execSecurity and execAsk undefined — the host treats undefined as "DELETE the per-session overrides via patch", so picking Default returns the session to whatever the operator configured at agents.defaults. Without this, the post-plan-mode fallback would lock back to Ask, which most operator configs don't want.

Plan as a dimension, not a permutation — the file-level header comment (mode-switcher.ts:1-16) explains why planMode is NOT mapped onto execSecurity: plan mode needs read-only exec for research, so blocking exec via execSecurity=allowlist would defeat its purpose. Plan mode + permission mode coexist, and resolveCurrentMode lets plan WIN for display purposes only.

Shadow-DOM-aware focus guard — getDeepActiveElement() at mode-switcher.ts:384-402 walks document.activeElement.shadowRoot.activeElement recursively (capped at depth 32) until it bottoms out at the real focus target. Without this, focus inside a <openclaw-chat-composer> Web Component's internal <input> returns the host element, the focus guard fails to bail, and Ctrl+1..6 steal keystrokes the user meant for typing. Two regression tests cover depth-1 (mode-switcher.test.ts:249-270) and depth-2 (mode-switcher.test.ts:272-290) Shadow DOM nesting.

Deliberate non-claim of role="menu" — mode-switcher.ts:328-339 explains why the dropdown does NOT declare role="menu": claiming the menu role without implementing arrow-nav, Home/End, roving tabindex, and focus trap would mislead assistive tech (per WAI-ARIA spec). Plain <button>s give native focus + Escape-on-chip, which is a real usable interaction with no false ARIA promise. Test asserting the role is absent: mode-switcher.test.ts:331-334.

Test coverage — mode-switcher.test.ts (388 LoC). Four describe blocks: resolveCurrentMode (10 cases including the PR-10 plan-auto interaction, the PR-8 Default/undefined handling, the sandbox deny regression), handleModeShortcut (8 cases for the modifier-exclusion matrix — Ctrl alone OK, Cmd/Shift/Alt all bail), focus guard (5 cases with the Shadow-DOM regression coverage), renderModeSwitcher (jsdom render) (5 DOM-shape cases).

ui/src/ui/chat/plan-resume.ts (21 LoC)

Single function, single test. Covered above in the "Plan-resume on web reconnect" section. The 21 LoC is the entire UI side of plan resume — everything else (decision persistence, runtime drain, idempotency-key correlation) lives in 2/6.

ui/src/ui/views/plan-approval-inline.ts (306 LoC)

The card that appears ABOVE the chat input bar when planApprovalRequest != null. Two visual variants share the same shell: the plan variant (3-button triad: Accept / Accept-allow-edits / Revise + an "Open plan" link) and the question variant (PR-10, AskUserQuestion: 1 button per option + optional "Other…" textarea).

Plan variant — renderInlinePlanApproval() at plan-approval-inline.ts:53-175. Buttons map to sessions.patch { planApproval: { action: "approve" | "approve-with-edits" | "revise" } }, fired by the host. The "Revise" button opens an inline textarea (matching Claude Code's web revision UX) with Ctrl/Cmd+Enter to submit and Escape to cancel; the chat input is hidden by the caller while the card is showing so users don't accidentally type into the wrong surface.

Title fallback — plan-approval-inline.ts:73-77: when the agent's exit_plan_mode call carries an explicit title (PR-9 Tier 1 contract), use it; when it's the generic "Plan approval requested" boilerplate or the legacy "Plan approval — …" prefix, fall back to "Agent proposed a plan". This means agents that don't yet emit Tier-1 titles still get a sensible headline. Test at plan-approval-inline.test.ts:47-68.

Question variant — renderInlineQuestion() at plan-approval-inline.ts:183-306. Same shell, different actions row. Carries a defensive guard: if the host forgets to wire onAnswerOption, the buttons render as disabled and a visible warning appears (⚠️ Question handler not wired (host did not pass onPlanApprovalAnswer). Buttons disabled.) — instead of mute no-op buttons that look interactive (plan-approval-inline.ts:196-222). This was a Copilot review fix (#3104741709) on the umbrella.

Offline behavior — when connected === false, every button across both variants is disabled and a banner appears ("Reconnect to resolve this plan. The approval stays pending while offline." for plans; analogous for questions). Tests assert disabled state at plan-approval-inline.test.ts:133-150 (plan) and plan-approval-inline.test.ts:181-210 (question).

"Other…" textarea state — PR-13 Bug 2 fix: caller owns questionOtherOpen / questionOtherDraft so the textarea state survives across re-renders, and Escape returns to the option list (instead of dismissing the entire card, which a window.prompt-based implementation would have done). Test at plan-approval-inline.test.ts:248-294.

Test coverage — plan-approval-inline.test.ts (295 LoC). 10 cases: nothing-when-no-request, generic-title fallback, button wiring, revise-editor draft+keyboard, offline plan, missing-handler warning, offline question, option click + Other handoff, free-text submit + cancel.

Supporting files (the rest of the diff)

• apps/shared/OpenClawKit/Sources/OpenClawKit/Resources/tool-display.json (+29 lines) — adds 5 plan-mode tool entries the native apps render: update_plan (🗺️), enter_plan_mode (🧭), exit_plan_mode (✅), plan_mode_status (🔍), ask_user_question (❓). Each carries detailKeys so the native side knows which payload fields to render in the tool card. The web UI doesn't read this file directly — it has its own tool-display-config.ts mirror — but native apps depend on this catalog being in sync.
• ui/src/styles/chat/plan-cards.css (+134 lines) — accent-bordered card with status-marker glyphs. Both ::-webkit-details-marker (Chromium/Safari) and ::marker (Firefox) suppressed so the custom chevron isn't doubled. :focus-visible outline added on <summary> (Copilot review fix from umbrella).
• ui/src/styles/chat/layout.css (+228 lines) — chat shell layout adjustments to make room for the inline approval card (it sits between the message thread bottom and the composer top, with deliberate top/bottom margins so the card visually associates with the composer it replaces, not the most-recent message).
• ui/src/styles/chat.css (+1) — single @import line wiring plan-cards.css into the chat bundle.
• ui/src/ui/chat/slash-command-executor.ts (+374) + .node.test.ts (+160) — /plan on|off|status slash-command handlers; pre-existing executor stub gets the plan-mode action arms. Tests pin the patch shape ({ planMode: "plan" | "normal" }) and the chip-state side effects.
• ui/src/ui/chat/slash-commands.ts (+12) — registers /plan in the slash-command catalog so it autocompletes from the / menu.
• ui/src/ui/chat/grouped-render.test.ts (+309 / -79) — extends the grouped-render fixture set with plan-card cases so the message-thread renderer's grouping logic correctly de-dupes consecutive plan events into a single rendered card.
• ui/src/ui/views/chat.ts (+477 / -106) — the integration host detailed above.
• ui/src/ui/app-render.ts + app-tool-stream.ts + app-chat.ts + app-view-state.ts + app.ts (~1300 lines net additions) — wires plan-approval-request lifecycle into the top-level chat app: stream-side detection of exit_plan_mode / ask_user_question events, view-state shape extensions for the approval-card local state (revise textarea, "Other…" textarea), patch-and-resume sequencing on approve/answer/reject.

Accessibility + i18n

Accessibility — six concrete things, all asserted by tests:

i18n — exactly one new key carries the plan-mode UI work: planViewToggle: "Toggle plan view sidebar", present in all 13 locale files (en, de, es, fr, id, ja-JP, ko, pl, pt-BR, tr, uk, zh-CN, zh-TW). The plan card / approval card / mode menu surface strings are not yet i18n'd in this PR — they're rendered from English literals in the Lit templates. This is intentional: extracting the approval/menu strings is a follow-up that depends on settling the user-facing copy after iter-3 of the umbrella. Tracking in #70101 carry-forward.

Edge cases + review-debt receipts

These are the non-obvious behaviors hardened by previous review cycles on the umbrella that survive into this PR. Calling them out so a reviewer doesn't unwittingly "simplify" them away:

Test coverage matrix

All tests use vitest with jsdom (@vitest-environment jsdom) and assert against real rendered DOM rather than snapshot strings, so a CSS-class rename or template restructuring doesn't accidentally pass. The test-LoC ratio (1067 / 873 ≈ 1.22×) is in line with the umbrella's UI test density.

Styling + CSS tokens

The new components use existing design tokens rather than introducing new color variables — every var() call falls back to a sensible literal so the components render correctly on a fresh checkout before theme tokens are loaded:

The accent-bordered-left treatment on plan cards (3px left border, 1px elsewhere) deliberately mirrors tool-cards.css so plan cards visually associate with tool output rather than reading as a separate UI surface. The approval card uses a warmer surface (caller-supplied) with a danger-button variant for Revise — --danger for the destructive action remains the standard system token.

The new layout adjustments in layout.css (+228 lines) carve out vertical space for the inline approval card by:

• Reserving a min-height region above the composer that grows when .plan-inline-card is present.
• Setting the composer's bottom-anchor offset to account for the card's measured height (CSS-only, no JS measurement).
• Ensuring the card doesn't overlap the message thread's scroll-bottom indicator (the "↓ New messages" jump button) by giving it a stacking-context that sits beneath that floating affordance.

Parity benchmark callout

Earlier prompt-parity benchmarking (same prompts hit OpenClaw + Codex + Claude Code) measured ~90% parity on response quality and ~95% parity on session lengths across the corpus, on top of plan mode landing. For UI specifically, two patterns in this PR are deliberate convergences:

• Inline plan-approval card — the "card above the composer with Accept / Accept-allow-edits / Revise" shape mirrors Claude Code's web UX. The Revise → inline textarea (rather than popup) is also lifted from there. Header comment at plan-approval-inline.ts:1-14 documents the parity intent.
• Mode-switcher chip — the chip-with-dropdown in the chat header matches Codex's run-mode toggle pattern (single chip showing current mode, dropdown to change, kbd shortcuts displayed in the menu). The 6-mode catalog (Default/Ask/Accept/Plan/Plan ⚡/Bypass) is OpenClaw-specific — the Plan ⚡ entry is the PR-10 auto-approve variant which is novel to this stack.

The convergences are about UX expectations (users coming from those tools find familiar surfaces) rather than implementation lifting — the underlying state model (plan as its own dimension coexisting with permission mode, the synthesized "Custom" mode for non-preset combos) is OpenClaw-specific and has no analogue in either source.

What a reviewer can verify in <30 min

Concrete checklist that exercises every load-bearing surface in this PR. Assumes the merge order is 1/6 → 2/6 → 3/6 → 4/6 (or that you're reviewing on the FULL bundle):

1. Spin up the gateway + open webchat (~3 min) — pnpm dev or equivalent; navigate to /chat.
2. Mode chip renders (~2 min) — chip should show "Default" with the shield icon. Click it; menu should show all 6 modes with Ctrl+1..6 hints. Press Escape; menu closes. Ctrl+4 (with focus NOT in the composer); chip switches to "Plan" with the checkmark-checkbox icon.
3. Focus guard works (~2 min) — click into the composer; type "ctrl+4" (literally). Should type the characters, NOT switch modes. (Exercises the Shadow-DOM-aware guard.)
4. Plan card renders inline (~5 min) — with a plan-mode-capable agent, send "make a 3-step plan to refactor the login component". The agent's update_plan event should render an expandable <details> card in the thread; click the summary to expand; verify 1/3 done style meta updates as the agent runs.
5. Approval card flow (~5 min) — when the agent calls exit_plan_mode, the inline approval card appears ABOVE the composer. Composer input hides. Click "Open plan" — the right sidebar opens with the formatted markdown. Click "Revise" — inline textarea opens; type feedback; Cmd+Enter submits; card vanishes; agent receives the revision via pendingAgentInjections and continues in plan mode.
6. Plan resume on reconnect (~5 min) — with a plan approval pending, kill the gateway. Card buttons disable; banner shows "Reconnect to resolve this plan…". Restart the gateway. Buttons re-enable. Click Accept; verify in network tab that chat.send fires with deliver: false + idempotencyKey: "plan-resume-<uuid>" (this is the plan-resume.ts primitive). Agent run resumes; no synthetic "continue" bubble appears in the transcript.
7. Question variant (~3 min) — with an AskUserQuestion-capable agent, ask something that triggers the tool. The same approval-card shell renders with one button per option (and Other… if allowFreetext: true). Click an option; verify the sessions.patch { planApproval: { action: "answer", answer: <text> } } fires.
8. i18n spot-check (~2 min) — switch the UI locale to (say) ja-JP or zh-CN; verify the plan-view toggle tooltip uses the localized string from planViewToggle.

Total: ~25 min for a full happy-path + offline + question + i18n sweep.

Suggested commands for reviewers

# Run the four new component test files in isolation:
pnpm --filter ui test -- ui/src/ui/chat/plan-cards.test.ts \
                        ui/src/ui/chat/mode-switcher.test.ts \
                        ui/src/ui/chat/plan-resume.node.test.ts \
                        ui/src/ui/views/plan-approval-inline.test.ts

# Sanity-check the i18n cleanup (verify deleted keys are genuinely unreferenced):
pnpm ui:i18n:check

# Spin up the gateway + open webchat for the manual smoke pass:
pnpm dev   # then open http://localhost:<gateway-port>/chat

The four-file test command above runs in <2s on a warm vitest cache and is the tightest smoke check that exercises every component-level invariant in this PR.

What This PR Does NOT Include

• Channel integration (/plan slash commands across text channels, Telegram attachment delivery) → [Plan Mode 5/6] Text channels + Telegram
• Automation + subagent follow-ups → [Plan Mode AUTOMATION] (#70089) + bundled in [Plan Mode FULL] (#70071)
• Docs (architecture, operator runbook) + QA scenarios → [Plan Mode 6/6] Docs, QA, and help
• Mobile (iOS/macOS/Android) plan UI — the UI here is web-only. Native apps consume the same tool-display.json plan-mode entries added in this PR but render their own approval cards.
• Accessibility audit for the approval card — basic role="region" + aria-label ship here; full audit (screen-reader walkthrough, contrast verification on the danger button, focus-ring on the textarea) is a follow-up cycle in #70101.
• i18n extraction of approval-card / menu strings — only the planViewToggle key is i18n'd here; copy for the approval card buttons and the mode menu labels is still English literals, pending iter-3 copy-finalization.

Carry-forward / deferred (tracked in #70101)

• Mobile (iOS/macOS/Android) plan UI — native apps consume the plan-mode entries added to tool-display.json here, but render their own approval cards. The native counterpart of plan-approval-inline.ts is a follow-up; the contract (Accept / Accept-allow-edits / Revise + Open plan, plus the question variant with N options + Other) is settled by this PR and can be ported as-is.
• Accessibility audit — basic landmarks (role="region" + aria-label) and keyboard contracts (focus-visible on the disclosure summary, Ctrl/Cmd+Enter to submit, Escape to cancel) ship here. A full screen-reader pass — including SR announcement of "approval pending" when the card appears, the contrast ratio of the danger-button variant on the dark card surface, and the focus-ring on the textarea — is a follow-up cycle.
• i18n extraction of approval-card / mode-menu strings — only the planViewToggle key is i18n'd in this PR. The approval card buttons ("Accept", "Accept, allow edits", "Revise", "Send revision", "Send answer", "Back to options") and the mode-menu labels ("Default permissions", "Ask each mutation", etc.) are still English literals. Extraction is queued behind iter-3 copy-finalization so we don't churn translators with copy that may still change.
• Tool-display strings i18n — the 5 plan-mode entries in tool-display.json carry English titles; localized variants will land with the broader tool-display i18n pass tracked separately.
