Affaan Mustafa 733295b44e docs: enhance 5 thin commands and add Rust API example
Commands enhanced with multi-language support, error recovery strategies,
and structured step-by-step workflows:
- build-fix: build system detection table, fix loop, recovery strategies
- test-coverage: framework detection, test generation rules, before/after report
- refactor-clean: safety tiers (SAFE/CAUTION/DANGER), multi-language tools
- update-codemaps: codemap format spec, diff detection, metadata headers
- update-docs: source-of-truth mapping, staleness checks, generated markers

New example:
- rust-api-CLAUDE.md: Axum + SQLx + PostgreSQL with layered architecture,
  thiserror patterns, compile-time SQL verification, integration test examples

# 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
