| bugfixing | Fix bugs in existing code through structured investigation and verification |
[F] Bugfixing — Fix Bugs in Existing Code
Goal: Systematically investigate, fix, and verify bugs with minimal side effects.
When to use: A bug has been reported or discovered in existing code.
CORE PRINCIPLES
- Reproduce first — Never fix what you cannot reproduce. A fix without reproduction is a guess.
- Minimal fix — Target the root cause with the smallest change possible. Do not refactor surrounding code during a bugfix.
- Regression check — Every fix must be verified against the original bug AND tested for side effects on related functionality.
INITIALIZATION
Design Log
Read {output_folder}/_progress/00-design-log.md. Check Current and Backlog for context.
Essential Guides
- Execution Principles — Document-first, plan-then-execute
- Session Protocol — Read dialog, verify plan, present status
- Inline Testing Guide — Verify fixes with Puppeteer before presenting
STEPS
Execute steps in ./steps-f/:
| Step | File | Purpose |
|---|---|---|
| 01 | step-01-reproduce.md | Reproduce and document the bug |
| 02 | step-02-investigate.md | Investigate root cause |
| 03 | step-03-fix.md | Implement the fix |
| 04 | step-04-verify.md | Verify fix, check regressions |
| 05 | step-05-document.md | Document fix, update tests |
Flow: 01 → 02 → 03 → 04 → 05
Critical Rules
- ALWAYS reproduce the bug before investigating
- ALWAYS identify root cause before writing a fix
- ALWAYS create a test that catches the bug before fixing
- ALWAYS run regression checks after fixing
- NEVER refactor surrounding code in the same fix
- NEVER fix symptoms — fix the root cause
AFTER COMPLETION
- Append a progress entry to
{output_folder}/_progress/00-design-log.mdunder## Progress:### [date] — Bugfix: [what was fixed] - Suggest re-running acceptance testing (Phase 5 [T]) to verify the fix
