+# Update Codemaps
+
+Analyze the codebase structure and generate token-lean architecture documentation.
+
+## Step 1: Scan Project Structure
+
+1. Identify the project type (monorepo, single app, library, microservice)
+2. Find all source directories (src/, lib/, app/, packages/)
+3. Map entry points (main.ts, index.ts, app.py, main.go, etc.)
+
+## Step 2: Generate Codemaps
+
+Create or update codemaps in `docs/CODEMAPS/` (or `.reports/codemaps/`):
+
+| File | Contents |
+|------|----------|
+| `architecture.md` | High-level system diagram, service boundaries, data flow |
+| `backend.md` | API routes, middleware chain, service → repository mapping |
+| `frontend.md` | Page tree, component hierarchy, state management flow |
+| `data.md` | Database tables, relationships, migration history |
+| `dependencies.md` | External services, third-party integrations, shared libraries |
+
+### Codemap Format
+
+Each codemap should be token-lean — optimized for AI context consumption:
+
+```markdown
+# Backend Architecture
+
+## Routes
+POST /api/users → UserController.create → UserService.create → UserRepo.insert
+GET  /api/users/:id → UserController.get → UserService.findById → UserRepo.findById
+
+## Key Files
+src/services/user.ts (business logic, 120 lines)
+src/repos/user.ts (database access, 80 lines)
+
+## Dependencies
+- PostgreSQL (primary data store)
+- Redis (session cache, rate limiting)
+- Stripe (payment processing)
+```
+
+## Step 3: Diff Detection
+
+1. If previous codemaps exist, calculate the diff percentage
+2. If changes > 30%, show the diff and request user approval before overwriting
+3. If changes <= 30%, update in place
+
+## Step 4: Add Metadata
+
+Add a freshness header to each codemap:
+
+```markdown
+<!-- Generated: 2026-02-11 | Files scanned: 142 | Token estimate: ~800 -->
+```
+
+## Step 5: Save Analysis Report
+
+Write a summary to `.reports/codemap-diff.txt`:
+- Files added/removed/modified since last scan
+- New dependencies detected
+- Architecture changes (new routes, new services, etc.)
+- Staleness warnings for docs not updated in 90+ days
+
+## Tips
+
+- Focus on **high-level structure**, not implementation details
+- Prefer **file paths and function signatures** over full code blocks
+- Keep each codemap under **1000 tokens** for efficient context loading
+- Use ASCII diagrams for data flow instead of verbose descriptions
+- Run after major feature additions or refactoring sessions
