Automated README summary
Automatically summarized from the README on 3 Nov 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
jevwire wires TypeSafe AI's Jev classifier into agent harnesses. It ships 7 MCP tools, an embeddable JevDecisionModel library with pure run* functions, and a Claude Code plugin whose hooks add advisory notes, tripwires, stop blocks and injection flags.
How it uses Jev
Jev scores typed questions over a state: tool-call text, fetched results, final messages. The library's run* functions return decisions (block/confirm) compared against thresholds in code; hooks turn scores into notes, tripwires or stop blocks addressed to Claude, never granting native permissions.
Primitives:choicescore
Technique worth stealing
Deterministic prefilter decides whether the model is consulted, so most tool calls never reach Jev.
Try it
npx -y @brainwires/jevwire as an MCP server with TYPESAFE_API_KEY, or npm i @brainwires/jevwire.
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.
