+# Agent Workflow Scripts
+
+Standard entry points that portable agent-workflow skills call, so a skill can
+run `.agents/bin/<name>` in any repo without knowing this repo's specific
+commands. Each script is a thin, repo-owned wrapper. The scripts listed below
+are required for this repo's portable contract; capabilities without a listed
+script are n/a here.
+
+| Script      | Purpose                                      | This repo runs                                                                                                     |
+| ----------- | -------------------------------------------- | ------------------------------------------------------------------------------------------------------------------ |
+| `setup`     | Install dependencies                         | `bin/setup`                                                                                                        |
+| `validate`  | Pre-push gate (`--changed`/`--all`/`--fast`) | `bin/ci-local`                                                                                                     |
+| `test`      | Run tests                                    | `(cd react_on_rails && bundle exec rake run_rspec:all_but_examples)` (includes JS tests via rake dependency)       |
+| `lint`      | Lint / format (`rake autofix` to fix)        | `(cd react_on_rails && bundle exec rake lint)` + Pro RuboCop + `pnpm run lint` + `pnpm start format.listDifferent` |
+| `build`     | Build / type-check                           | `pnpm run build` + `pnpm run type-check` + OSS and Pro RBS validation when present                                 |
+| `docs`      | Docs checks                                  | `script/check-docs-sidebar` + `bin/check-links`                                                                    |
+| `ci-detect` | CI change detector                           | `script/ci-changes-detector [base-ref]` (default `origin/main`)                                                    |
+
+`validate` intentionally delegates base discovery to `bin/ci-local`; do not pass
+a normal `<base-ref>` argument. See
+[`internal/contributor-info/local-ci-contract.md`](../../internal/contributor-info/local-ci-contract.md)
+for the local CI contract.
+
+Non-command policy lives in [`../agent-workflow.yml`](../agent-workflow.yml).
+Workflow-specific checks such as `actionlint` and `yamllint .github/` stay in the
+PR-processing workflow for `.github/**` changes rather than the general build entrypoint.
