Automated README summary
Automatically summarized from the README on 20 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A Claude Code Stop hook for coding agents: it reads the turn's transcript locally and blocks a turn that claims done when files changed and no check passed since.
How it uses Jev
When files changed and no check passed, jev-belay sends one Jev call with four questions over a state of task, final message, and run counts. The claims_done answer above the threshold blocks the turn; claims_verified, verification_applies and outcome shape the reason.
Primitives:choicescore
Technique worth stealing
Establish run facts from the transcript first, then judge the closing message next to that evidence, instead of judging wording alone.

Model judgments from README excerpts
Project signals use repository metadata, an existing summary and the first 700 README characters, not the full project. “Not found” means not detected in that material; it does not establish absence. These are the original judgments with recorded models and dates, not source audits or run results.

Evidence
These signals use repository metadata, an existing summary and at most 700 cleaned README characters. ≥ 0.60 means reported in that excerpt; ≤ 0.40 means not found there. The middle band is inconclusive. None is a source-code audit or a test result. The runnable-tool question excludes research experiments; the recommendation question asks for a learning shortlist, not a quality verdict.
