ln-830-code-modernization-coordinator — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited ln-830-code-modernization-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 code modernization. Delegates OSS replacement and bundle-size work to isolated child runs, records machine-readable worker summaries, and emits a final coordinator summary.
| Aspect | Details |
|---|---|
| Input | Audit report, target module, or modernization scope |
| Output | Aggregated modernization report with durable worker artifacts |
| Workers | ln-831 (OSS replacer), ln-832 (bundle optimizer) |
| Runtime | .hex-skills/modernization/runtime/runs/{run_id}/ |
