Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
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
The skill conditionally runs "npx -y @mermaid-js/mermaid-cli@latest" at runtime (which fetches and executes code from the npm registry, e.g. https://registry.npmjs.org/@mermaid-js/mermaid-cli), and this fetched package is required for the mandatory syntax verification step, so it is a runtime external dependency that executes remote code.
