onboard

# Onboard to Current Project Generate a comprehensive onboarding package for a developer joining this project. ## Instructions 1. Read the primary skill: - `${CLAUDE_PLUGIN_ROOT}/skills/codemap-explain/SKILL.md` — explanation methodology 2. Ensure output directories exist: `docs/codemap/diagrams/` — create if missing. 3. Launch the **architect-explainer** agent with a prompt to perform the full onboarding: **Phase 1 — Project Analysis:** - Read root files (README.md, CLAUDE.md, package.json/requirements.txt, docker-compose, .env.example) - Scan directory structure, identify tech stack, find entry points - Read model definitions and key configuration **Phase 2 — Generate Documentation:** - Create `docs/codemap/ONBOARDING.md` (overview, stack, directory structure, entry points, how to run, key concepts) - Create `docs/codemap/ARCHITECTURE.md` (components, data flow, layers, external dependencies) **Phase 3 — Generate 3 Diagrams** (via codemap-diagram skill): - `docs/codemap/diagrams/architecture.drawio` — C4 container diagram - `docs/codemap/diagrams/main-flow.drawio` — primary user flow - `docs/codemap/diagrams/erd.drawio` — database ERD **Phase 4 — Verification (MANDATORY):** - Verify all 3 diagrams were created: architecture.drawio, main-flow.drawio, erd.drawio - If any diagram is missing, generate it before proceeding - Verify all files are `.drawio` (not `.mmd` or any other format) **Phase 5 — Summary:** - List all generated files with descriptions - Show diagram file paths (and the inline preview, if the client rendered one) - Suggest next steps
