Retrospective: Evolve Self-Testing Rules from Real Cases

Workflow

Step 1: Read Cases

Read .claude/skills/1k-retrospective/references/case-studies.md. Count cases since the last <!-- Retrospective completed --> marker. If fewer than 3 new cases, report "Not enough new cases" and stop.

Step 2: Analyze Patterns

For each case, extract root cause category and which self-testing section (1-8) could have caught it, or "NEW" if not covered. Aggregate counts per pattern.

Step 3: Identify Gaps and Weak Spots

• Gaps: patterns appearing 2+ times marked "NEW" → candidates for new check items
• Weak spots: patterns appearing 3+ times already covered → check item needs stronger wording or more specificity

Step 4: Propose Changes
