Overview & result
Evaluates incoming pull requests in ~0.5s for ~$0.00007 each, testing 6 real PRs in the demo video to flag security risks and syntax blunders without expensive LLM round-trips.
From the original post
got Jev to review my PRs. ~200x cheaper than Claude and it answers in half a second
6 real PRs in the video. $0.00007 each. 1,000 PRs = 7 cents vs ~$14.50 on Opus 5
paste a diff → ONE call to @typesafeai → 14 typed checks come back as probabilities:
hardcoded secret, sql injection, touches auth, deletes tests, breaks api, migration, debug leftovers, does the description actually match the diff, blast radius, reviewer effort…
code turns that into a verdict: BLOCK / security review / nits / merge. anything a critical check isn't sure about (0.35–0.65) gets escalated to a human or a big model instead of guessed
How Jev fits in the loop
- Intercept git diff patch on PR open or synchronize webhook.
- Evaluate diff chunks using Jev Score across policy, style, and risk dimensions.
- Approve safe clean diffs instantly; route questionable changes to senior engineers.
- Report status checks directly to GitHub PR timeline.
How to reproduce
- Review author video showing 6 distinct GitHub PR diffs evaluated in sequence.
- Extract git diff patches and pass risk criteria to Jev Score.
- Block PRs scoring below quality thresholds while fast-passing trivial updates.
Why this build matters
Turns slow, multi-dollar CI/CD LLM review steps into sub-cent, near-instant pre-merge hygiene checks.
Limitations
- Author reported benchmark figures; not independently validated by JevForAgents.
- Cannot generate creative refactoring suggestions or complex logic rewrites.
- High-risk changes still need comprehensive human peer review.
