Bug Debugging

Diagnose bugs, plan fixes, and execute - end-to-end.

Argument Routing

| Argument | Mode | |----------|------| | <prompt> | Self-execute on current host (default) | | --delegate | Delegate to the other host (Codex when current is Claude, Claude when current is Codex; current host comes from SessionStart Current host:) | | --delegate <prompt> | Same with prompt |

Strip the --delegate flag before passing the prompt to the execution path.

Execution

1. Diagnose:

   • Self-execute (default): Spawn Agent({ subagent_type: "coral:debugger", prompt: "--deep " + prompt }). Wait for the agent to return its diagnosis in <Output_Format> structure.
   • Delegate (--delegate): Run coral-cli <other-host> debugger -i "<--deep prompt>" --work-dir "<work_dir>" -d (<other-host> = Codex if current is Claude; Claude if current is Codex). Capture job from Job <job> <launchState> (session <session>), then run coral-cli wait --jobs "<job>" --embed → the terminal output always includes Result path: <path>; read that path for the full artifact and treat inline preview text as optional convenience for findings. On error, stop with the error message. Verify cited file:line references. Drop findings with incorrect references.

2. Record diagnosis: Write the diagnosis to CORAL_PROJECT/plans/debug-{short-bug-description}.md using the debugger's output format (Symptom, Reproduction Path, Hypothesis Log, Root Cause, Fix Specification). Gate on hypothesis verdicts:

   • One confirmed root cause → proceed to step 3.
   • Multiple hypotheses survived → present to user, ask which to pursue before proceeding.
   • All refuted or inconclusive → stop and report findings to user.

3. Plan fix: Invoke Skill({ skill: "coral:plan", args: (if --delegate: "--delegate ") + "round=3 --no-handoff fix-{short-bug-description}" }). The plan references CORAL_PROJECT/plans/debug-{short-bug-description}.md for diagnosis context. Plan should include: what to change, why, and how to verify the fix.

4. Execute fix: Invoke Skill({ skill: "coral:ralph", args: (if --delegate: "--delegate ") + "implement the plan from step 3" }).

5. Project validation: If project instructions define workflow rules (e.g., review gates, post-implementation steps), follow them.
