Reflection Skill

Purpose

Improve future Claude Code sessions by learning from mistakes and user corrections. Updates skill files in the target project's .claude/skills/ directory.

This is a meta-skill - it modifies other skills based on session learnings.

When to Run (Explicit Triggers Only)

Only activate when the user explicitly requests reflection:

• "reflect"
• "don't do this again"
• "remember this for next time"
• "update your skills"
• "learn from this"

Never run automatically - always wait for explicit user trigger.

Where Rules Go

Rules are written to the target project's skill files (NOT the plugin repository):

If the target project doesn't have .claude/skills/, create it with a starter structure.

Process

1. Analyse the completed session

   • Review conversation for corrections
   • Identify repeated mistakes
   • Note stated preferences

2. Extract atomic, durable rules

   • One rule per concept
   • "Do X" or "Never Y" format
   • Date-stamped for tracking

3. Check for contradictions

   • Read existing skill files
   • Flag conflicting rules
   • Ask user to resolve

4. Update appropriate skill file(s)

   • Append to ## Learned Rules section
   • Preserve existing formatting
   • Keep changes minimal

5. Commit changes separately from code

   • Use semantic commit message
   • Include rule summary in body

Rule Quality Bar

A rule must be:

• Durable: Will apply to future work in this project
• Actionable: Clear imperative ("Always X", "Never Y")
• Specific: Not too broad or vague
• Non-contradicting: Doesn't conflict with existing rules

Rule Format

- [YYYY-MM-DD] RULE_TEXT (source: BRIEF_CORRECTION_CONTEXT)

Examples:

- [2025-01-09] Always eager load relationships in service methods that return collections (source: booking service review)
- [2025-01-09] Never use axios - use Inertia router instead (source: corrected 3x in dashboard component)
- [2025-01-10] Use FloatingLabelInput for all form fields (source: user preference stated)

Starter Skill Structure

When creating .claude/skills/ in a new project:

# Lessons Learned

## Purpose
Project-specific rules learned from Claude Code sessions.

## Learned Rules
<!-- Reflection appends here -->

Git Commit Format

chore(skills): reflect session learnings

- Added: [rule summary]
- Source: [correction context]
- File: .claude/skills/[filename].md

What NOT to Learn

Do not create rules for:

• One-time exceptions
• User's momentary preferences
• Context-specific decisions
• Temporary workarounds

Only learn patterns that should always apply.
