AI DevKit · Guide structured debugging before code changes by clarifying expected behavior, reproducing issues, identifying likely root causes, and agreeing on a fix plan with validation steps. Use when users ask to debug bugs, investigate regressions, triage incidents, diagnose failing behavior, handle failing tests, analyze production incidents, investigate error spikes, or run root cause analysis (RCA).

1# Local Debugging Assistant23Debug with an evidence-first workflow before changing code.45## Hard Rule6- Do not modify code until the user approves a selected fix plan.78## Workflow9101. Clarify11- Restate observed vs expected behavior in one concise diff.12- Confirm scope and measurable success criteria.13- Before investigating, search for similar past incidents: `npx ai-devkit@latest memory search --query "<observed behavior>" --tags "debug,root-cause"`14152. Reproduce16- Capture minimal reproduction steps. For user-flow bugs, make the repro a `dev-smoke` check that fails before the fix and passes after.17- Capture environment fingerprint: runtime, versions, config flags, data sample, and platform.18193. Hypothesize and Test20For each hypothesis, include:21- Predicted evidence if true.22- Disconfirming evidence if false.23- Exact test command or check.24- Prefer one-variable-at-a-time tests.25264. Plan27- Present fix options with risks and verification steps.28- Recommend one option and request approval.2930## Validation31- Confirm a pre-fix failing signal exists.32- Confirm post-fix success using the `verify` skill — including regression verification for bug fixes.33- Summarize remaining risks and follow-ups.34- Offer `dev-retro` to prevent recurrence; run only if the user agrees.35- Store root cause and fix for future sessions: `npx ai-devkit@latest memory store --title "<root cause>" --content "<diagnosis and fix>" --tags "debug,root-cause"`3637## Task Tracing38…
