What it is
pi-warden supervises Pi coding agents, catching risky actions, ignored rules, stuck loops, unverified done claims, security issues, runaway output, and wasted context. It usually feeds issues back to the agent rather than interrupting the user.
How it uses Jev
Jev judges irreversible and off-task tool calls before bash/write/edit run, checks every write and edit against project Markdown rules, detects repeated failures, and evaluates done claims. Verdicts are returned to the agent as a held tool result or a short steer.

Technique worth stealing
Returning Jev's verdict to the agent as a held tool result or steer instead of a user dialog.
Try it
pi install npm:pi-warden, then /warden enable and /warden test.
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
