Automated README summary
Automatically summarized from the README on 2 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
jev-guard is a security hook for coding agents such as Claude Code, Codex, Copilot, Gemini, Cursor, pi, OpenCode and ACP clients. It risk-scores tool calls, flags prompt injection in tool results, and checks skills and plugins.
How it uses Jev
Jev answers typed questions over session context: a risk Score (0–3), an approval Noul, and a user_requested Noul. Code in src/guard.js turns these into deny, ask, or allow before a tool runs, and flags untrusted content after it returns.
Primitives:scorenoul
Technique worth stealing
Keep the policy in readable code and ask Jev narrow typed questions instead of using a proprietary classifier.

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.
