1 medium severity finding. This skill can be installed but you should review these findings before use.
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.
Potentially malicious external URL detected (high risk: 0.80). 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.
