validation-patterns — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited validation-patterns (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

A pipeline like km.train(df) → km.register(result, name=...) can have 100% unit coverage on km.train AND 100% integration coverage on km.register while the chain fails because result is missing a field the next step needs (the "fake-integration" failure mode).
Defense: A release-blocking regression tier above Tier 3 — a test that executes the full pipeline against real infrastructure AND asserts a deterministic fingerprint over the output. Any change that alters observable behavior flips the fingerprint and blocks release.
