workers-best-practices

MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 0.90). The skill explicitly requires fetching the live best-practices doc at runtime (e.g., https://developers.cloudflare.com/workers/best-practices/workers-best-practices/) and instructs the agent to prefer that retrieved content to drive code-review/writing decisions, so remote content directly controls agent instructions and is a required dependency.
