Automated README summary
Automatically summarized from the README on 27 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A Claude Code PreToolUse hook that stops the agent from writing, committing, or sending secrets. Known key formats are blocked locally; unknown high-entropy strings are judged by Jev (TypeSafe) after masking, so checking for a leak never causes one.
How it uses Jev
For unknown high-entropy strings, Jev receives the first 3 characters, length, charset, and up to 300 characters of the surrounding line with the value masked. If Jev scores secret ≥ 0.80, the action is blocked; 0.30–0.80 or Jev unavailable asks the user.
Primitives:score
Technique worth stealing
Mask secrets before sending to the model, so leak detection never leaks.
Try it
Set TYPESAFE_API_KEY, clone repo, add hook to ~/.claude/settings.json.
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.
