TypeSafe Jev decision layer for Pi coding agent.

Automated README summary

Automatically summarized from the README on 1 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.

What it is

A Pi coding agent extension that uses Jev to gate risky tool calls and judge outputs, returning calibrated probabilities for safety decisions.

How it uses Jev

Jev judges bash, write, and edit calls before execution via a gate, and judges bash/codemode outputs for secrets and failure classes. Results are used to flag, confirm, or append advice.

Primitives:noulscorechoice

Technique worth stealing

Batch multiple typed questions into one Jev request to reduce round trips.

Try it

pi install npm:@y0usaf/pi-jev

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.
