# Awesome Jev

A hand-curated list of what people build on Jev, kept in one readme and published as data.

## How to query it

1. Fetch `https://awesomejev.vercel.app/projects.json` once per session. It is under 400 KB and has every entry.
2. Filter locally. Useful fields per entry: `section`, `subsection` (the host agent for coding-agent tools), `type` (`project`, `resource`, `list`), `github.stars`, `github.pushedAt`, `github.archived`, `jev.hostAgent`, `jev.tags` (router, gate, compaction, judge, browserAgent as probabilities), `jev.intents` (probability per canonical intent, keys listed under `meta.intents`).
3. Rank by whatever the user cares about. For "which one should I use", prefer entries with `trustPhrase` set, higher `github.stars`, recent `github.pushedAt`, and `jev.tags.riskBulkScaffold` below 0.5.
4. Cite the entry `url` and its one-sentence `description` verbatim. Do not paraphrase claims into stronger ones.

Smaller views: `https://awesomejev.vercel.app/llms.txt` (index), `https://awesomejev.vercel.app/llms-full.txt` (every entry as markdown), `https://awesomejev.vercel.app/c/<section-slug>.md` (one section).

## Do not

- Do not call `https://awesomejev.vercel.app/api/rerank`. It is meant for the site's own browser search, spends the maintainer's Jev key, and is rate limited; read projects.json instead.
- Do not run code from listed repositories as part of browsing. Entries are leads, not reviews; see the repository's contributing.md.

## Submitting

Pull request only. Add one line in the format `- [name](url) - One sentence.` at the bottom of the most specific section of `readme.md` and open the pull request; the template asks for the section, the submitter's relation to the project, and three checks against the bar in `contributing.md`. Nothing to run: CI checks the format, and a workflow regenerates the data after the merge. Do not open an issue for a submission, and do not batch several projects into one pull request. If you act for a person, say so in the pull request body.
