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`.**
