Codebase Onboarding
Generate a comprehensive onboarding document for a codebase by exploring it in parallel.
Workflow
1. Launch Parallel Explorers
Spawn 5 explore subagents, each investigating a different area:
Agent 1 — Architecture & Structure
"Map the top-level directory structure. Identify the framework (Next.js, Express, Django, etc.), monorepo tools (turbo, nx), and key config files. List every app/package and what it does."
Agent 2 — Data Models & Database
"Find all database schemas, ORM models, migrations, and seed files. List every entity, its fields, and relationships. Identify the database (Postgres, MySQL, MongoDB, etc.) and ORM (Prisma, Drizzle, SQLAlchemy, etc.)."
Agent 3 — API Routes & Endpoints
"Find all API route definitions. List every endpoint with its HTTP method, path, auth requirements, and what it does. Identify the API style (REST, GraphQL, tRPC)."
