Individual skill

lesson-learned

Analyze recent code changes via git history and extract software engineering lessons. Use when the user asks 'what is the lesson here?', 'what can I learn from this?', 'engineering takeaway', 'what did I just learn?', 'reflect on this code', or wants to extract principles from recent work.

# Lesson Learned

Extract specific, grounded software engineering lessons from actual code changes. Not a lecture -- a mirror. Show the user what their code already demonstrates.

## Before You Begin

**Load the principles reference first.**

1. Read `references/se-principles.md` to have the principle catalog available
2. Optionally read `references/anti-patterns.md` if you suspect the changes include areas for improvement
3. Determine the scope of analysis (see Phase 1)

**Do not proceed until you've loaded at least `se-principles.md`.**
