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 eval viewer (eval-viewer/viewer.html) loads and executes remote JavaScript at runtime from https://cdn.sheetjs.com/xlsx-0.20.3/package/dist/xlsx.full.min.js (used for .xlsx rendering), so the skill fetches and relies on external code that will execute in the user's browser.
