Debug

Debug and remediate bugs with severity-gated workflows. Progressive disclosure from quick triage through comprehensive remediation planning. Integrates with planning skill for complex fixes and artifact-tracking for progress. Also provides a post-incident retrospective mode: classifies post-merge gaps against a failure taxonomy and emits a patch-plan addendum. Use when running /fix:debug or /fix:bugfix-commit commands. /fix:debug auto-invokes the retrospective workflow when the prompt contains: 'Codex had to patch', 'gaps after merge', 'we missed', or 'regression after phase'.
