skill-best-practices

SUSPICIOUS. The skill's main purpose is benign documentation and workflow guidance, and its local file access is proportionate. The main concern is trust expansion: it instructs the agent to load another skill and to run an unpinned third-party npm CLI (`skills`) for remote validation, which is inconsistent with Anthropic's surfaced official plugin install path. No credential harvesting, covert exfiltration, or clearly malicious behavior is present, so this is not malware, but the transitive trust and package-execution pattern make the skill higher risk than a simple best-practices guide.
