Codebase

Designs REST, GraphQL, or gRPC APIs from requirements — picks the right protocol for the use case, models resources and operations, defines schemas (Zod for internal, OpenAPI/GraphQL SDL/proto for specs), and writes the spec to .context/architecture/api/. Use when the user asks to design an API, sketch out endpoints, model a schema, plan a service's interface, or says things like "what should the API look like for X", "design endpoints for Y", or "how should clients talk to this service".

Structures codebases and repositories by project type, runtime boundary, domain ownership, and maintenance workflow. Use when the user asks how to organize a codebase, scaffold a repo, split a monolith, design a monorepo, move files, choose folders, clean up LLM-generated project layout, or decide where app, package, service, test, config, docs, and deployment code should live. Covers Apple apps, web apps, websites, Expo/React Native, Cloudflare/full-stack services, CLIs, agent skills/plugins, Home Assistant integrations, and GitOps/homelab projects.
