fix（修复）

Fix: Behavior Correction Skill

Activated when user gives feedback with "fix:" prefix. Finds the root cause of the mistake, improves rules/skills/hooks, and fixes the current issue.

Trigger

• Messages with fix: prefix
• Behavior correction feedback: "fix this", "correct", "why not", "why missing"

Procedure

Step 0. TodoWrite (MANDATORY — first action, no exceptions)

Before any analysis or text output, register TODO items:

TodoWrite([
  { id: "fix-0", content: "fix: {user feedback summary} — root cause analysis", status: "in_progress" },
  { id: "fix-1", content: "Root cause fix", status: "pending" },
  { id: "fix-2", content: "Fix current issue", status: "pending" },
  { id: "fix-3", content: "Completion report + cleanup", status: "pending" },
])

Step 0 is the first tool call after /fix activation. Text output before TodoWrite = violation.

1. Root Cause Analysis (5-Why depth)

Don't stop at the direct cause. Dig at least 3 levels deep:

Why 1: What went wrong? (symptom — the immediate mistake)
Why 2: Why did I make that decision? (judgment — missing knowledge/rule)
Why 3: Why was that knowledge/rule missing? (structural — skill/rule gap)

• Fixing only Why 1 = patching a symptom. It recurs in a different form.
• Why 2-3 reveal structural causes (platform ignorance, DRY violation, etc.) — these go into rules/skills.
• Search for the responsible skill/rule/hook files (Grep/Glob)

2. Root Cause Fix (Prevent Recurrence)

Priority (check in order — stop at the first match):

When fixing:

• Skill is 1st priority — if the problem is a skill's incomplete procedure, fix the skill. Don't skip to failed-attempts.md
• Skill improvements must follow skill-kit upgrade procedure (direct script/topic file edits allowed)
• Rule location must be confirmed via AskUserQuestion
• failed-attempts.md recording is only for cases not covered by skill/rule/hook — no duplicate recording if root cause is already reflected in a skill or rule

3. Fix Current Issue + Resume Original Work

• After root cause fix, immediately resolve the current problem
• If unsure what to execute, AskUserQuestion — don't skip execution because you don't know the command
• Verify fix results (build/test/run)
• Continue the originally intended work with the corrected approach — don't just clean up wrong artifacts, complete the original task
• Resume the originally intended work with the corrected approach

4. Completion Report + Cleanup

Fix complete:
- Root cause: {what was missing}
- Improvement: {which file was modified and how}
- Current fix: {result of fixing the current issue}

After reporting, delete all TODO items created in Step 0 — fix TODOs are temporary session-level tracking only; must not persist after completion.

Anti-patterns

• Repeating "already fixed" without actually fixing the root cause
• Patching only the current issue without improving skills/rules/hooks
• Text response without TodoWrite after /fix activation
• Recording in failed-attempts.md when the root cause is a skill defect (skill fix is 1st priority)
• Stopping at Why 1 — fixing the symptom without asking Why 2-3 (structural cause)
• Not cleaning up TODO/Task after completion — must delete all fix TODOs when done
