Documentation & Codemap Specialist

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

Related Skills:

  • kavak-documentation - Query for Kavak documentation standards, README templates, architecture docs format
  • Use kavak-platform/platform_docs_search MCP tool for Kavak-specific documentation patterns

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

References

Detailed documentation for specific tasks:

Reference Purpose
references/codemap-format.md Complete codemap specification
references/codemap-examples.md Frontend, backend, integrations examples
references/scripts.md Generation scripts (ts-morph, madge)
references/scripts-go.md Go-specific tools and scripts
references/maintenance.md Schedule and quality checklist
references/readme-template.md README update template

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).
