Template for generating lessons-learned.md

## Purpose
Aggregate lessons learned from workflow sessions, categorized by functional domain and severity.

## File Location
`.claude/skills/workflow-progress/lessons-learned.md`

## Update Strategy
- **Incremental mode**: Merge new session lessons into existing categories, update frequencies
- **Full mode**: Regenerate entire lessons document from all sessions

## Structure

```markdown
# Workflow Lessons Learned

## Best Practices (Successes)

### {Domain_Category}
- {success_pattern_1} (sessions: {session_id_1}, {session_id_2})
- {success_pattern_2} (sessions: {session_id_3})

### {Domain_Category_2}
...

---

## Known Challenges

### High Priority
- **{challenge_title}**: {description}
  - Affected sessions: {session_id_1}, {session_id_2}
  - Resolution: {resolution_strategy}

### Medium Priority
- **{challenge_title}**: {description}
  - Affected sessions: {session_id_3}
  - Resolution: {resolution_strategy}

### Low Priority
...

---

## Watch Patterns

### Critical (3+ sessions)
1. **{pattern_name}**: {description}
   - Frequency: {count} sessions
   - Affected: {session_list}
   - Mitigation: {mitigation_strategy}

### High Priority (2 sessions)
...

### Normal (1 session)
...
```

## Data Sources
- Lessons: `manifest.json` -> `archives[].lessons.{successes|challenges|watch_patterns}`
- Session metadata: `.workflow/.archives/{session_id}/workflow-session.json`

## Aggregation Rules (Use maestro delegate)

**Command Pattern**:
```bash
maestro delegate "
PURPOSE: Aggregate workflow lessons from session data
TASK: • Group successes by functional domain • Categorize challenges by severity (HIGH/MEDIUM/LOW) • Identify watch patterns with frequency >= 2 • Mark CRITICAL patterns (3+ sessions)
MODE: analysis
CONTEXT: @.workflow/.archives/manifest.json
EXPECTED: Aggregated lessons with frequency counts
CONSTRAINTS: analysis=READ-ONLY
" --role analyze --mode analysis --rule workflow-skill-aggregation --cd .workflow/.archives
```

**Severity Classification**:
- **HIGH**: Blocked development >4 hours OR repeated in 3+ sessions
- **MEDIUM**: Required significant rework OR repeated in 2 sessions
- **LOW**: Minor issues resolved quickly

**Pattern Identification**:
- Successes in 3+ sessions → "Best Practices"
- Challenges repeated 2+ times → "Known Issues"
- Watch patterns frequency >= 2 → "High Priority Warnings"
- Watch patterns frequency >= 3 → "CRITICAL"

## Formatting Rules
- Sort by frequency (most common first)
- Include session references for traceability
- Use bold for challenge titles
- Keep descriptions concise but actionable
