pi-jev-sentinel

Pi coding-agent extension: TypeSafe Jev checks for tool calls, tool outputs and replies (prompt injection, approvals, secret scrubbing, task pinning)

How it uses Jev

A guard for coding agents, built on TypeSafe's Jev model: it checks what the agent does, reads, and says. One set of checks, three hosts: a Pi extension, and a plugin for Claude Code and Codex CLI .
