pi-jev-auto-mode is a permission gate extension for the Pi coding agent that uses a decision-only model (Jev) to judge shell commands, file writes, and edits. It layers a deterministic policy engine with a semantic judgment layer that fails closed, offering granular threshold tuning and per-rule calibration. The project is notable for its thoughtful design around safety, trust boundaries, and auditable decisions in agent tooling.

Target audience: AI agent developers, security engineers, DevOps
