# adapto:schema-apply The **gated writer** of the schema pair. It reads `.adapto/schema-plan.json` (produced by `adapto:schema-design`) and creates the **Article categories** and **custom collections** it describes via the `adapto` CLI. It is **idempotent and re-runnable** — existing collections/categories are reused or updated, never duplicated. ## When to use - After `adapto:schema-design` produced (and you've eyeballed or hand-edited) `.adapto/schema-plan.json`, and you're ready to create those collections + categories in Adapto. - Triggers: "apply the schema", "create the collections", "build my schema in Adapto". ## When not to use - No plan file yet → run `adapto:schema-design` first. - Seeding content rows into the collections → `adapto:content-seed`. ## Inputs - **`.adapto/schema-plan.json`** — the approved plan (collections, categories, language). Missing/invalid → stop and route to `adapto:schema-design`. - **The working tenant** — confirm it explicitly; never assume the saved/active one.
