why — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited why (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.

Call the sipcode:audit_latest_session MCP tool to produce a forensic report of the user's most recent Claude Code session.
If the user provides a session ID prefix (e.g., "audit session 3bca35e2"), pass it as the session_id argument. Otherwise, omit and the tool will pick the most recent session across all projects.
