Detect and triage OWASP AST09 No Governance — no skill inventory, no approval workflow, orphaned skills after offboarding, regulated-data exposure with no audit trail, unreachable skills inside managed SaaS platforms, and bilateral-receipt audit logging (admission + outcome records). Use when designing or auditing a compliance-grade skill audit trail, when a skill lives inside a SaaS copilot the security team cannot scan, when distinguishing a signed-tamper-evident log from an operator-editable one, or when mapping an AST09 finding to EU AI Act Article 12 logging obligations.

From the source SKILL.md

Pattern: Knowledge. The decision rule this category turns on: a log an operator controls can be edited after the fact; a receipt an independent verifier can cryptographically check cannot — "we have logging" and "we have compliance-grade audit evidence" are different claims, and most AST09 mitigation lists conflate them.

What this skill does

ast09-no-governance is a community-contributed Claude Code skill in the web-security sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/ast09/ and loads when your prompt matches the skill's trigger.
