Update Claude.md with learnings

What TO Add

• Philosophy/conventions - e.g., "No backwards compatibility unless explicitly requested"
• Gotchas - Non-obvious things that cause bugs repeatedly
• Commands or scripts - New ways to run/test things
• Structure changes - When directories or files move
• Recent significant changes - New features, refactors, or capabilities added

What NOT to Add

• Specific technical details about a single bug fix
• Implementation details that are obvious from code
• Temporary workarounds
• One-off decisions that won't recur
• Verbose explanations of how something works

Rule of thumb: If it's something you'd tell a new developer joining the project, add it. If it's just details about today's work, skip it.

Instructions

1. Read current CLAUDE.md - Understand what's already documented
2. Review recent work - Check git log/diff for significant changes; extract meta learnings
3. Update conservatively - Keep CLAUDE.md <300 lines. Remove outdated info if needed.

Output

After updating, summarize:

• What was added
• What was removed (if anything)
• Current line count
