rosetta

Documents the authentication layer of a project — sessions, tokens, middleware, guards, decorators, the permission model. Use when the user says "document auth", "write docs for authentication", "document the login flow", "document how sessions work", or similar. Runs the write-docs engine with an auth-specific playbook, and asks the user at the start whether to run inline (pause for clarifications) or in background (best-judgment, report when done).

Documents the database layer of a project — schema, tables, entities, relationships, ORM models. Migrations are covered separately by /rosetta:doc-migrations. Use when the user says "document the database schema", "document the tables", "document the data model", "write docs for the entities", or similar. Runs the write-docs engine with a db-specific playbook, and asks the user at the start whether to run inline or in background.

Documents the migration workflow of a project — how to add, apply, and roll back migrations; the tool in use; the team's process around destructive changes. Schema itself is covered by /rosetta:doc-db. Use when the user says "document migrations", "document how to add a migration", "write the migration runbook", or similar. Runs the write-docs engine with a migrations-specific playbook, and asks the user at the start whether to run inline or in background.

Documents the cross-cutting patterns in a codebase — decorators, middleware, filters on controllers, factory / repository / service conventions, the transversal techniques a contributor needs to recognize. Use when the user says "document the patterns", "document the conventions", "document how decorators are used here", "document the middleware stack", or similar. Runs the write-docs engine with a patterns-specific playbook, and asks the user at the start whether to run inline or in background.

Scaffolds a Rosetta.md documentation site into the current project at rosetta-docs/. Use when the user wants to set up docs, initialize documentation, bootstrap rosetta-docs, add a docs folder, or says things like "init rosetta", "scaffold starlight docs", "start a docs site for this repo". Clones the latest tagged release of rosetta-template (resolved from the remote at runtime — no manual version pin), installs deps with the user's preferred package manager (pnpm or npm), starts the dev or docker server, and verifies via /health.
