A Claude Code skill: an authoritative reference for TypeSafe AI's Jev, the "System One" model. You send it a state plus typed questions (Choice / Score / Noul) and it returns typed answers with calibrated probabilities. It doesn't generate text. The skill covers the API contract, primitives, confidence calibration and its quirks, where Jev is weak
How builders describe it
Claude Code skill documenting Jev typed decisions, calibration quirks, and classify-route-rerank-gate patterns, with a dependency-free Java client and replayable fixtures.
The decision Jev makes
Label a change, score its risk, pick the relevant file, or decide whether a coding agent should continue.
Where it fits
Code review and coding agents are full of small questions: is this change risky, what kind of fix is this, which file matters. These projects answer them with Jev and route the rest to people or bigger models. All 450 coding & code review projects →
