claude-code - 💡(How to fix) Fix [Bug] Ultraplan ready notification fires before cloud agent completes execution

Bug Description Bug: ◆ ultraplan ready notification fires prematurely, before the cloud agent has finished

Severity: Medium — causes wasted user trust and incorrect downstream actions in local Claude Code.

Reproduction:

1. From local Claude Code, trigger an Ultraplan session (either via /ultraplan slash command or by creating a RemoteTrigger routine).
2. Wait until the local CLI shows ◆ ultraplan ready · https://claude.ai/code/session_<id>?from=cli.
3. Open the session URL in the browser.

Expected: The notification arrives only after the cloud agent has finished its work — at minimum, the agent's final message is written and (if applicable) the commit/branch the agent was asked to produce is pushed.

Actual: The ◆ ready notification arrives while the agent is still running. The system-reminder text accompanying it (The remote ultraplan session produced a plan and is waiting for approval. Tell the user to open <URL> to review it.) is also factually incorrect at that point — no plan has been produced yet.

Consequences in local Claude Code:

• The local instance reads the system-reminder literally and tells the user the plan is ready.
• It then exits plan mode and proposes to start implementation — based on a plan that doesn't exist yet.
• In one observed case (2026-05-27), the cloud agent eventually timed out (Ultraplan terminated: no approval after 90 minutes) without ever producing output, meaning the local instance had already moved past a plan that never materialized.

Suggested fix (any of these would help):

1. Only emit ◆ ready after the cloud agent's terminal turn completes. If the agent is asked to commit work, only after the push succeeds.
2. Change the system-reminder text so it doesn't assert "produced a plan" when that hasn't been verified — e.g. The remote ultraplan session is open for review at <URL>. Status: <running|finished|timed-out>.
3. Include a machine-readable status (running / completed / timed-out) in the notification payload so local Claude can branch on it rather than trusting prose.

Environment:

• Local Claude Code CLI on Linux
• Triggered both via /ultraplan slash command and via RemoteTrigger API (run_once_at schedule mode) — both surfaces show the bug.
