Why does it ask only one question per invocation?

Each run maps to one primitive subcommand so the shell stays explicit: pipe incident text or a diff in, ask a noul, choice, or score question, then enforce thresholds in jq or later steps.

How do I turn a noul probability into a pass/fail gate?

Check the exit code for success, then filter JSON in jq — the README gates regressions with jq -e on .answers.result.noul — so policy lives downstream, not in the CLI.

How do provider setup and output differ?

Set TYPESAFE_API_KEY, CLOUDFLARE_API_TOKEN with account ID, or AI_GATEWAY_API_KEY, pick with --provider, and get JSON by default or text with --output text; stdout keeps only results.

Will secrets or logs break my parsing?

No: stdout holds only a successful result and diagnostics go to stderr, so piped JSON stays parseable; use --output text only when you want human reading.

How do I install the client and use it in CI?

Install with go install github.com/stefafafan/jev@latest, or build from source with go build -o jev . For GitHub Actions use stefafafan/setup-jev. The repository's own pr-risk.yml workflow sends a pull request diff to Jev through Cloudflare and applies a corresponding merge-risk label.

Where does the state come from, and can I pass a file?

State always comes from stdin. Use ordinary shell redirection for a file, for example jev noul "Is this urgent?" < incident.txt, or pipe another command such as git diff or kubectl diff into it. Each invocation asks exactly one question through a primitive subcommand.

What does the exit code tell me?

The CLI reports whether evaluation succeeded through its exit code; it does not turn a judgment into policy. Put thresholds downstream. stdout contains only a successful result and diagnostics are written to stderr, so piping the JSON into jq works cleanly.

Q: What does the exit code tell me?

The CLI reports whether evaluation succeeded through its exit code; it does not turn a judgment into policy. Put thresholds downstream. stdout contains only a successful result and diagnostics are written to stderr, so piping the JSON into jq works cleanly.

Go Unix CLI that pipes state on stdin into one Jev question — noul, choice, or score — across TypeSafe, Cloudflare, and Vercel providers, printing machine-readable JSON and signaling success by exit code.

About this project

An unofficial, provider-neutral Unix client for Jev from TypeSafe AI. Written in Go. Use stefafafan/setup-jev to install a released jev binary on a GitHub Actions runner. For a working CI example, see this repository's pr-risk.yml workflow. It sends a pull request diff to Jev through Cloudflare and applies a corresponding merge-risk label.

Highlights

State always comes from stdin with one question per run: noul for yes/no, choice with repeated --option flags, score with ordered --level flags.
Works with TypeSafe, Cloudflare Workers AI, and Vercel AI Gateway via env keys, keeping Jev primitive fields and token usage in JSON output.
Built for pipes and CI: stdout holds only the result, diagnostics go to stderr, and jq can gate on thresholds like noul probability.
Ships a setup-jev GitHub Action plus a PR-risk workflow that sends a diff through Cloudflare and applies a merge-risk label.

Watch out

Unofficial client; it reports a judgment and leaves thresholds and policy to downstream code. Copy reviewed against the repository README on 2026-10-04, not from running it.
