pi-warden: Guardrails for Pi that steer instead of interrupt: enforces your project rules on every write, holds only hard

by DevMortimer · Agent Tool · ★ 178

Last updated: · Indexed by AgentSkillsHub · Auto-synced every 8h

Security audit verdict: SAFE · quality 68/100

None of the 42 rules matched — no credential harvesting, no data exfiltration, no curl-pipe-shell installer. Scanned against 42 published rules built on the SlowMist agent-security taxonomy, refreshed every 8 hours.

The quality score combines nine heuristic checks of the repo and its README: completeness, clarity, specificity, examples, structure, agent readiness, step-by-step content, instruction quality and security notes. It rates how well the project explains itself to an agent, not the code.

About pi-warden

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.

How this security grade is produced

Grades come from a rule-based scan built on the SlowMist agent-security taxonomy: 42 published rules, covering credential harvesting, data exfiltration, curl | sh installers and more. 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.
