W012: Unverifiable external dependency detected (runtime URL that controls agent)
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
Potentially malicious external URL detected (high risk: 0.90). The skill instructs the agent at runtime to "Read only the relevant reference files" which are fetched from raw GitHub URLs (e.g. https://raw.githubusercontent.com/planetscale/database-skills/main/skills/mysql/references/primary-keys.md), so those external files would directly control agent guidance and are required dependencies.
