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

/phx:compound # Auto-detects from recent session contextEach unit of engineering work should make subsequent units easier — not harder.
$ARGUMENTS provided, use as descriptiongit diff, .claude/plans/{slug}/progress.md for recent completions
Only document non-trivial problems that required investigation.
Create .claude/solutions/ directory if it doesn't exist (run mkdir -p .claude/solutions). Then search .claude/solutions/ for relevant keywords using Grep.
If found: Create new (different root cause), Update existing (same root cause, new symptom), or Skip.
Extract from session context: module, symptoms, investigation steps, root cause, solution code, and prevention advice.
Validate frontmatter against compound-docs/references/schema.md, then create file using compound-docs/references/resolution-template.md.
Write-blocked fallback: if writing to .claude/solutions/ is denied by permissions, do NOT silently drop the solution. Output the full solution doc inline (fenced markdown the user can paste), then suggest /phx:permissions to allow .claude/solutions/ writes for next time.
When user says "that worked", "it's fixed", "problem solved", "the fix was" — suggest /phx:compound.
When /phx:deps-audit produces a BLOCK-severity finding that the user investigates and confirms is a real malicious pattern (not a false positive), suggest:
Caught a high-severity finding in<pkg>@<version>. Run/phx:compoundto capture this for future audits?
If accepted, the resulting solution doc goes to .claude/solutions/supply-chain/<pkg>-<cve_or_pattern>.md and includes the exact rule-id + snippet + diff window that triggered the finding. This compounds the audit corpus: future runs of /phx:deps-audit grep solutions/supply-chain/ for snippet matches and pre-elevate severity on known-bad patterns.
Always prompt; never auto-write. Solution docs are durable and shape future trust calls — the user reviews before committing.
