Instructions
1. Gather Context
Review the session or incident by checking:
- Recent git history:
git log --oneline -20
- Changed files:
git diff --stat HEAD~5
- Any error logs, test outputs, or debug reports from the session
- Plan files if working from a plan
2. Identify Key Events
Build a timeline of what happened:
- What was the initial goal or trigger?
- What approaches were tried?
- What worked and what did not?
- What was the root cause (if debugging)?
- What was the final resolution?
3. Extract Lessons
For each significant event, note:
- What was surprising or unexpected?
- What would be done differently next time?
- What patterns or anti-patterns were discovered?
- What tools or techniques proved useful?
4. Write the Journal Entry
Save to docs/journal/ or docs/retros/ (create the directory if needed). Use the filename format YYYY-MM-DD-topic.md.
