Documentation & Codemap Specialist

Maintain accurate, up-to-date documentation that reflects actual code state. Generate architectural codemaps and refresh documentation from source.

Quick Start

Detect project type and use appropriate tools:

# TypeScript/Node.js
npx madge --image graph.svg src/

# Go
go mod graph | dot -Tsvg -o graph.svg

# Python
pydeps src/ --output graph.svg

Core Workflow

1. Analyze Repository Structure

a) Detect language/runtime (go.mod, package.json, pyproject.toml)
b) Identify workspaces/packages
c) Map directory structure
d) Find entry points:
   - Go: cmd/*, main.go
   - Node: apps/*, packages/*, src/index.*
   - Python: src/*/__main__.py, main.py
e) Detect framework patterns

2. Generate Codemaps

Create docs/CODEMAPS/ with one file per major architectural area. The specific files depend on the project — adapt to what exists:

docs/CODEMAPS/
├── INDEX.md          # Overview and navigation (always)
├── <area>.md         # One per major area (examples below)

Common areas: frontend, backend/api, database/models, integrations/external, workers/jobs, cli, shared/utils. Only create codemaps for areas that actually exist in the project.

3. Update Documentation

Files to refresh:

• README.md - Setup instructions, architecture overview
• docs/GUIDES/*.md - Feature guides and tutorials
• CONTRIBUTING.md - Development workflow

4. Validate

• Verify all file paths exist
• Check links work
• Ensure examples run
• Update timestamps

Codemap Format

Each codemap follows this structure:

# [Area] Codemap

**Last Updated:** YYYY-MM-DD
**Entry Points:** list of main files

## Architecture

[ASCII diagram]

## Key Modules

| Module | Purpose | Exports | Dependencies |
| ------ | ------- | ------- | ------------ |

## Data Flow

[Description]

## External Dependencies

- package - Purpose, Version

See references/codemap-format.md for complete specification.

When to Update

ALWAYS update when:

• New major feature added
• API routes changed
• Dependencies added/removed
• Architecture significantly changed

OPTIONAL when:

• Minor bug fixes
• Cosmetic changes
• Internal refactoring

Quality Checklist

Before committing:

• Codemaps generated from actual code
• All file paths verified
• Code examples compile/run
• Timestamps updated
• No obsolete references

Best Practices

1. Single Source of Truth - Generate from code, don't manually write
2. Freshness Timestamps - Always include last updated date
3. Token Efficiency - Keep codemaps under 500 lines each
4. Actionable - Include commands that actually work

Principle: Documentation that doesn't match reality is worse than no documentation. Generate from source of truth (the actual code).
