## Suggest a CAFE entry through your agent

Help the person you assist suggest a story for [news](https://parol6.build/news) or a project for the [directory](https://parol6.build/directory).

1. Check the page for an existing entry. You can also POST JSON to `/api/listCafeNews` or `/api/listCafeProjects`. Do not submit a duplicate.
2. Read the source repository and gather the fields below. Cite repository file paths for each stack claim. Do not invent evidence.
3. Draft the exact issue title and all fields. Say whether this is the person's own work. Show the person the draft, including any public attribution.
4. File only after the person approves that exact issue. Use the matching form in `joelhooks/rat-stack`.
5. Submit once. Do not spam or retry through another surface when the result is uncertain. Check GitHub for the issue first.

### Fields

- **News:** HTTPS URL, title and one-line summary (each at most 280 characters), kind (release, post, video or launch), optional repo (`owner/repo`), optional author GitHub login and X handle, and why it is CAFE.
- **Project:** HTTPS repo URL, title (at most 280 characters), one-line summary (at most 350 characters), and evidence for Cloudflare, Alchemy, Foldkit and Effect. Each evidence string names a file path and what it proves, in at most 280 characters. Write `Not found` for a letter without evidence.
- Disclose the person's connection to the entry in either form. Leave unknown optional fields blank.

### File the approved issue

Use `gh issue create --repo joelhooks/rat-stack --template cafe-news.yml` for a story, or `gh issue create --repo joelhooks/rat-stack --template cafe-project.yml` for a project. Use only the approved title and fields.

If gh is unavailable or cannot use issue forms, give the person the matching prefilled URL and the approved fields:

- News: `https://github.com/joelhooks/rat-stack/issues/new?template=cafe-news.yml&title=URL_ENCODED_APPROVED_TITLE`
- Project: `https://github.com/joelhooks/rat-stack/issues/new?template=cafe-project.yml&title=URL_ENCODED_APPROVED_TITLE`

Replace the title placeholder with the URL-encoded approved title. Prefill form fields with URL-encoded values using their form IDs as query keys. The person can review and file the issue in GitHub.

Joel or the desk reviews each suggestion. Listing is not guaranteed.
