Description (problem / solution / changelog)

GPT 5.4 Enhancement v3 — PR 1/6

Tracking: #66345 | Issue: #66346 Priority: P0 — CRITICAL | Gap closure: ~35%

Problem

GPT 5.4 on OpenClaw answers factual, computational, and system-state questions from training data instead of calling tools. This is the #1 root cause of the behavioral gap vs Hermes Agent.

Changes

extensions/openai/prompt-overlay.ts:

• Added OPENAI_GPT5_TOOL_ENFORCEMENT constant with 8 mandatory tool-use categories:
  • Arithmetic/math, hashes/encodings, timestamps, system state, file contents, git, current facts, network checks
• Appended to stablePrefix in resolveOpenAISystemPromptContribution

Hermes Reference

agent/prompt_builder.py lines 207-218 — <mandatory_tool_use> block within OPENAI_MODEL_EXECUTION_GUIDANCE.

Verification

Test GPT 5.4 — all should call tools, not answer from memory:

• "What time is it?" → date
• "What's the sha256 of 'hello'?" → echo -n hello | sha256sum
• "How much free disk space?" → df -h
• "What branch am I on?" → git branch --show-current
• "What's 2^64?" → terminal/code execution

Note

Currently placed in stablePrefix. PR 3 (#66348) will promote tool_enforcement to a first-class sectionOverrides key, at which point this moves from stablePrefix to sectionOverrides.tool_enforcement.

1. Act, Don't Ask: Concrete examples showing when to act on obvious defaults vs when to ask
2. Tool Persistence: Retry-on-failure directive — diagnose and adjust instead of surrendering

Description (problem / solution / changelog)

GPT 5.4 Enhancement v3 — PR 3/6

Tracking: #66345 | Issue: #66348 Priority: P1 — MEDIUM | Type: Architecture

Problem

PR 1 (#66371) adds mandatory tool-use categories for GPT-5 via stablePrefix. This works but conflates two concerns:

• execution_bias: how the agent executes (act first, don't plan)
• tool_enforcement: when it must use tools (mandatory categories)

Providers should be able to override these independently.

4 files changed:

1. src/agents/system-prompt-contribution.ts — Add "tool_enforcement" to ProviderSystemPromptSectionId union
2. src/agents/system-prompt.ts — Add buildOverridablePromptSection call for tool_enforcement (after execution_bias, before stablePrefix)
3. extensions/openai/prompt-overlay.ts — Add OPENAI_GPT5_TOOL_ENFORCEMENT constant, wire into sectionOverrides.tool_enforcement
4. extensions/openai/index.test.ts — Update all 7 contribution assertions to include tool_enforcement in sectionOverrides, factor the shared stablePrefix expectation into an EXPECTED_GPT5_STABLE_PREFIX helper constant

Benefits

• Separation of concerns: execution bias and tool enforcement are distinct prompt sections
• Provider extensibility: Google Gemini (PR 6, #66379) uses tool_enforcement for its own operational directives
• Testability: each section can be tested independently
• Default empty: providers that don't need tool enforcement get an empty section (zero noise)

GPT 5.4 Enhancement v3 — PR 4/6

Tracking: #66345 | Issue: #66350 Priority: P2 — SECURITY

Problem

OpenClaw loads workspace context files (SOUL.md, AGENTS.md, identity.md, etc.) into the system prompt without scanning for injection patterns. A malicious or compromised context file could override agent behavior.

Design Decision: Conservative Pattern Matching

To avoid false-positives on legitimate SOUL.md persona files, patterns are deliberately narrow:

• Role impersonation requires explicit override phrasing (ignore/disregard/forget/bypass + previous/prior/above + instructions/rules/prompts). Patterns like "you are now" and "act as" are NOT flagged because they are legitimate in persona files.
• DAN is case-sensitive (uppercase-only) so the common name "Dan" does not trigger.
• Exfiltration requires send ... to https:// pattern — bare URLs, curl, and wget are NOT flagged on their own.
• HTML comment injection requires specific phrases inside the comment, not just keywords.

This is defense-in-depth, not an all-or-nothing filter. The scanner wraps flagged content in a data fence; the model can still read it, just with appropriate skepticism.

Changes

New: src/agents/context-file-injection-scan.ts

• 7 injection pattern detectors:
  1. instruction-override: explicit override phrasing only
  2. system-override: override/disregard/bypass + safety-related target
  3. privilege-escalation: admin override, developer mode, jailbreak, etc.
  4. privilege-escalation-dan: case-sensitive \bDAN\b
  5. html-comment-injection: HTML comments containing override phrases
  6. invisible-unicode: 3+ consecutive zero-width/format chars
  7. exfiltration: send [data] to https:// pattern
• scanForInjection(content) → { detected: boolean, labels: string[] }
• sanitizeContextFileForInjection(content) → wraps flagged content in <untrusted-context-file> data fence
• escapeFenceClosingTag() prevents fence-breaking attacks where payload includes </untrusted-context-file>

New: src/agents/context-file-injection-scan.test.ts — 15 unit tests covering clean content, persona file false-positive avoidance, DAN vs Dan, all 7 patterns, and the fence-breaking attack vector.

Modified: src/agents/system-prompt.ts

• buildProjectContextSection now wraps each file's content through sanitizeContextFileForInjection after existing sanitizeContextFileContentForPrompt
• Clean files pass through unchanged (zero overhead for normal use)

Hermes Reference

agent/prompt_builder.py lines 55-73 — equivalent _INJECTION_PATTERNS scanner run before context file inclusion.

Verification

All 15 unit tests cover the implemented patterns and the deliberate false-positive avoidance.

GPT 5.4 Enhancement v3 — PR 5/6

Tracking: #66345 | Issue: #66351 Priority: P2 — LOW | Type: Quality Polish

Problem

OpenClaw's GPT-5 execution bias says "Act first, then verify if needed" but doesn't specify what to verify. Hermes provides a structured checklist. The critical missing dimension is grounding — checking that claims are backed by tool output, not training data.

Changes

extensions/openai/prompt-overlay.ts — Append verification subsection to OPENAI_GPT5_EXECUTION_BIAS:

### Verification
Before finalizing your response, check:
- Correctness: does the output satisfy every stated requirement?
- Grounding: are factual claims backed by tool outputs, not training data?
- Coverage: did you address every part of the request?
- Formatting: does the output match the requested format or schema?
- Safety: if the next step has side effects, confirm scope before executing.

Impact

Modest quality improvement on multi-step tasks. The Grounding check specifically reinforces mandatory tool use (PR 1) — even if GPT-5 skips a tool call, the verification step prompts it to notice the gap.
