Remix and React Router: 29 are direct, 2 are workarounds. Remix and React Router recipes cite the page they were derived from, or the specification when the step is generic. Version read for Remix and React Router: React Router framework mode. ## Version and documentation read Version React Router framework mode (npm latest react-router 8.5.1; Remix v2 @remix-run/node 2.17.5, read 2026-11-04); docs at reactrouter.com Read on 2026-11-04 Recipes 29 direct, 2 workaround, 0 not possible on the platform robots.txt [reactrouter.com/how-to/resource-routes](https://reactrouter.com/how-to/resource-routes). No robots helper; a resource route (loader without default export) at app/routes/robots\[.\]txt.ts returns text. Sitemap [reactrouter.com/how-to/resource-routes](https://reactrouter.com/how-to/resource-routes). Sitemap via a resource route returning XML; no built-in generator. Structured data [reactrouter.com/start/framework/route-module](https://reactrouter.com/start/framework/route-module). No JSON-LD helper in the route-module docs; render the script element in the route component, which is server rendered. Status codes [reactrouter.com/how-to/status](https://reactrouter.com/how-to/status). throw data("Not Found", { status: 404 }) from a loader sets the status and renders the ErrorBoundary. Headers and redirects [reactrouter.com/how-to/headers](https://reactrouter.com/how-to/headers). headers export on route modules; loader headers are not sent unless returned from headers. Content negotiation [reactrouter.com/how-to/middleware](https://reactrouter.com/how-to/middleware). Server middleware can inspect the Accept header before loaders run. llms.txt [reactrouter.com/how-to/resource-routes](https://reactrouter.com/how-to/resource-routes). Resource route app/routes/llms\[.\]txt.ts. OpenAPI No first-party doc: No OpenAPI page in the framework docs. Serve public/openapi.json or return it from a resource route. [The checklist table for Remix and React Router (framework mode)](https://agentreadychecklist.com/platform/remix-react-router/checklist/) shows every row with its first step. ## Verify with Ora Remix and React Router (framework mode) has a direct recipe for 29 rows, and Ora's catalogue (read 2026-11-05) names a matching check for 25 of them, among them AR-FIND-01, AR-FIND-03, AR-FIND-04. After the steps are live, one audit shows which of those fixes the score picks up. ```bash npx ax@0.10 audit https://example.com --min-score 70 ``` One row that Ora checks is a workaround or not possible on Remix and React Router: [AR-READ-05](https://agentreadychecklist.com/checklist/ar-read-05/) (code-fence-validity, workaround). Ora scores the site as it stands, so a row the platform cannot satisfy stays open until the workaround is in place. Run it again with `--force` after a deploy, so the audit skips Ora's cache.

Check the host WAF separately. Read 2026-11-04. [reactrouter.com/how-to/resource-routes](https://reactrouter.com/how-to/resource-routes) ### [AR-FIND-02](https://agentreadychecklist.com/checklist/ar-find-02/): Answers on one first-party pagerecipe Publish each answer once, as a page on your own domain. Put the fact (price, limit, version) in the page text, give the page one stable address, and link it from the home page and from llms.txt. Keep the page current: a second, older copy elsewhere on the site is the usual way an agent cites the wrong figure. Generic step from the AgentReady specification; not platform-specific.

Read 2026-11-04.

For static pages add prerender: true or a list of paths. Read 2026-11-04. [reactrouter.com/start/framework/rendering](https://reactrouter.com/start/framework/rendering) ### [AR-READ-02](https://agentreadychecklist.com/checklist/ar-read-02/): Real HTTP status codesrecipe In a loader throw data("Not Found", { status: 404 }) when the record is missing; add a catch-all route that throws the same so unknown paths return 404. Return 429 with a Retry-After header from middleware when throttling. Read 2026-11-04. [reactrouter.com/how-to/status](https://reactrouter.com/how-to/status) ### [AR-READ-03](https://agentreadychecklist.com/checklist/ar-read-03/): Home page with real linksrecipe Use Link from react-router on the home page; it renders a href anchors in the server HTML. Read 2026-11-04. [reactrouter.com/start/framework/routing](https://reactrouter.com/start/framework/routing) ### [AR-READ-04](https://agentreadychecklist.com/checklist/ar-read-04/): Docs that answer agent tasksrecipe For each of your top five agent tasks, write a page that holds the steps as text, in order, with the exact names of the buttons, fields and settings. Steps that exist only in an image, a video or a script-built widget are not in the response a plain fetch receives. Fetch the page with curl and grep for the step. Generic step from the AgentReady specification; not platform-specific.

Use an MDX plugin for Vite and write fenced blocks with a language, or render
