Update CLAUDE.md

Maintains project documentation by analyzing git history and syncing CLAUDE.md with code changes.

Quick Start

1. git log -1 --format="%H" -- CLAUDE.md → find baseline
2. git diff <hash>..HEAD --name-only → list changed files
3. Read CLAUDE.md → identify sections → map changes → propose → apply → check master

Workflow

Phase 1: Discover Changes

# Find last CLAUDE.md commit
git log -1 --format="%H" -- CLAUDE.md

# Get all changes since then
git diff <last-claude-commit>..HEAD --name-only
git log <last-claude-commit>..HEAD --oneline

If CLAUDE.md not in git (new file or untracked):

Ask user: "CLAUDE.md isn't tracked in git. How long since it was last updated?"

Options:

• "1 week" → git log --since="1 week ago" --oneline --name-only
• "1 month" → git log --since="1 month ago" --oneline --name-only
• "Specific date" → git log --since="YYYY-MM-DD" --oneline --name-only

Phase 2: Analyze CLAUDE.md Structure

Read the actual CLAUDE.md first. Extract:

• All ## and ### section headings
• What each section documents (modules, commands, config, etc.)
• File/directory patterns mentioned in each section

Build a dynamic mapping: changed file → relevant section(s)

Example discovery:

Sections found:
- "## Configuration" mentions: config.py, .env, environment variables
- "## Middleware System" mentions: middlewares.py, filters.py
- "## Project Structure" lists: all module files
→ If middlewares.py changed, update "Middleware System" + "Project Structure"

Phase 3: Propose Updates

For each affected area:

1. Existing sections needing updates - list specific changes
2. New sections to add - describe what they'd cover

Present to engineer:

Changes detected since last CLAUDE.md update (<commit>):

**Files changed:**
• path/to/file.py - <brief description of change>
• path/to/new_module.py - NEW FILE

**Sections to UPDATE:**
• [Section Name] - reason
  └─ files: x.py, y.py

**Potential NEW sections:**
• [Proposed Title] - would document X
  └─ files: new_module.py

Which changes should I document?

Wait for engineer confirmation before proceeding.

Phase 4: Apply Updates

After engineer approval:

1. Read affected sections from current CLAUDE.md
2. Apply changes matching existing style
3. Add new sections in appropriate locations

Phase 5: Resolve Master Conflicts (AFTER applying updates)

git diff master -- CLAUDE.md

IMPORTANT: Run AFTER applying updates to catch:

• Sections modified in master that we also modified
• New sections added in master we might overwrite

If master differs:

1. git show master:CLAUDE.md → fetch master version
2. Identify conflicting sections
3. Merge: keep additions from both, prefer more complete version
4. Show engineer the diff before finalizing

Conflict strategy:

• Only in master → keep it
• Only in current → keep it
• Both modified → merge carefully, ask if unclear

Quality Checks

Before finalizing:

• All identified changes documented
• No merge conflicts with master
• Matches existing formatting style
• Cross-references still valid
