ln-820-dependency-optimization-coordinator — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited ln-820-dependency-optimization-coordinator (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.

Type: L2 Domain Coordinator Category: 8XX Optimization
Runtime-backed coordinator for cross-stack dependency upgrades. Detects package managers, delegates to one worker per manager, records machine-readable worker summaries, and emits a final coordinator summary.
| Aspect | Details |
|---|---|
| Input | Project path plus optional upgrade policy |
| Output | Aggregated dependency upgrade report with per-worker results |
| Workers | ln-821 (npm), ln-822 (nuget), ln-823 (pip) |
| Runtime | .hex-skills/dependency/runtime/runs/{run_id}/ |
