pi-warden Your is a request. pi-warden is the check behind it. On every write and edit, Jev judges the change against the rules in your and quotes the broken rule back into the agent's own context. The same channel names slop, breaks retry loops, calls out "done" when no test ran, keeps large tool output small, triages async subagent reports, and holds the rare destructive command. You keep working. The agent gets a nudge instead of you getting a dialog. Measured: 150 paired headless runs broke a project rule 6 times with pi-warden off and 0 times with it on. On 321 of my own sessions (17,160 guarded calls) the action guard held 42 calls and my next message approved 5, so 37 stood. A judgment costs about 1,000 input tokens (roughly $0.00004) and lands in about 0.3 s, which is why it can fire on every guarded call. The verdicts above are real output from .

Grades come from a rule-based scan built on the SlowMist agent-security taxonomy, covering 11 red-flag categories including credential harvesting, data exfiltration, and curl | sh installers. It is a first-layer scan, not a manual audit — we say so rather than overstate it.
The scale of the problem is documented independently: Liu et al. (2026), in a study of 31,132 agent skills, report that 26.1% contain security vulnerabilities. Our own full-catalog census is published as a citable open dataset.
