Automated README summary
Automatically summarized from the README on 21 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A Claude Code plugin that places TypeSafe's Jev model at four points around the agent's tool calls: output filtering, auto mode, start hints and a claims check. Every feature has a switch and every hook fails open.
How it uses Jev
Jev answers typed questions on tool output windows (relevance and injection), on ten yes/no hazards plus request intent for auto mode, on effort/model and skill hints at prompt submit, and on claims against tool results at stop. Probabilities drive filtering, allow/deny/hold, hints and one send-back.
Primitives:choicescore
Technique worth stealing
Ask Jev small typed questions only where code cannot decide, and fail open on any error.
Try it
Install via /plugin install jev --marketplace /jev-claude-plugin, or run claude --plugin-dir with TYPESAFE_API_KEY set.
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.
