# Atomic Documentation

Create or update context documentation following the atomic documentation system.

## Execution Instructions

When this skill is invoked:

**MANDATORY FIRST STEP:** Use the Read tool to read `context/workflows/manage-atomic-doc.md` (relative to project root). DO NOT proceed without reading this file first - it contains the complete workflow including Phase 0 (index check) that you MUST follow.

After reading the workflow file:

1. Parse `$ARGUMENTS`:
   - `create <layer>/<domain>/<name>` → new doc
   - `update <path>` → modify existing
   - No args → ask user what they want to create/update

2. Follow ALL phases in the workflow file, starting with Phase 0.

## Quick Reference

| `foundations` | Capabilities (combines blocks) | exec-tsx.md, test-unit-vitest.md |
| `stacks` | Complete project setups | cli-bun.md, api-pnpm-fastify.md |
