What it does
Awesome Jev is an agent skill from valentynkit/awesome-jev-typesafe. Find open-source projects, SDKs, and articles built on TypeSafe's Jev (System One typed decisions). Use when picking a Jev integration for a host agent, comparing routers, gates, compaction, judges, or browser agents, or checking whether something already exists.
Its SKILL.md is about 620 tokens, which your agent loads only when the skill is triggered. The skill folder holds 194 other files, including scripts (for example `.github/ISSUE_TEMPLATE/config.yml`, `.github/PULL_REQUEST_TEMPLATE.md` and `.github/dependabot.yml`).
It sits in Productivity & Automation, covering Browser automation. It works with GitHub. The repository describes itself as: Typed decisions with TypeSafe's Jev, the first System One model. The licence is CC0-1.0.
When your agent uses it
- Picking a Jev integration for a host agent
- Comparing routers
- Checking whether something already exists
Example prompts
- “/awesome-jev”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Fetch https://awesomejev.vercel.app/projects.json once per session. It is under 400 KB and has every entry.
- Filter locally. Useful fields per entry: section, subsection (the host agent for coding-agent tools), type (project, resource, list)…
- Rank by whatever the user cares about. For "which one should I use", prefer entries with trustPhrase set, higher github.stars, recent…
- Cite the entry url and its one-sentence description verbatim. Do not paraphrase claims into stronger ones.
What it can do on your machine
Read from SKILL.md and the folder at commit 8a635aa. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/, which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
awesomejev.vercel.app
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Awesome Jev loads about 619 tokens when it runs. Until then it costs about 69 tokens; SKILL.md has 276 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Awesome Jev
A hand-curated list of what people build on Jev, kept in one readme and published as data.
How to query it
- Fetch
https://awesomejev.vercel.app/projects.jsononce per session. It is under 400 KB and has every entry. - 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 undermeta.intents). - Rank by whatever the user cares about. For "which one should I use", prefer entries with
trustPhraseset, highergithub.stars, recentgithub.pushedAt, andjev.tags.riskBulkScaffoldbelow 0.5. - Cite the entry
urland its one-sentencedescriptionverbatim. 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.
