What it does

Audit an agent's harness against the four rings: containment, guides, sensors, permissions. Use when the user asks whether their agent setup is safe, wants a review of sandboxing / permissions / hooks / AGENTS.md guardrails, or asks what a bad session could break. Read-only: reports the blast radius and a hardening list, changes nothing. Do NOT use for context layout (context-audit) or cost routing (gate-check).

Audit the four rings

Theory: The four rings and Harness practice. Build from the outside in: containment, guides, sensors, permissions. The order matters because each ring must hold when every ring inside it fails, a guide can be ignored, a sensor can miss, an approval can be misclicked; a wall does not care.

Core rule

Report and rank; never harden anything yourself. The audit's one organising question is the blast radius: describe the worst session possible under the current setup and what it costs. If the user asks you to apply fixes afterwards, that is a normal edit session, not this skill.
