phx:brief — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited phx:brief (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.

The primary manifest — the file an agent reads to learn what this artifact does.
Interactive walkthrough of a plan's reasoning, decisions, and solution shape. Designed for developers who need to understand a plan in 1-2 minutes instead of reading the full document.
Plans answer "what to do" but bury "why." This skill bridges that gap with an interactive walkthrough.
