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

Use this skill for local development setup and hardware-free validation. Root AGENTS.md is the current gate authority.
The top-level parent alone performs venv/dependency installation, build, and clean-wheel smoke where network or dependency resolution is needed. Write-capable leaves return affected offline-gate evidence and never request network or sandbox relaxation.
