1 medium severity finding. This skill can be installed but you should review these findings before use.

Medium

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 includes a client-side runtime dependency that fetches and executes remote JavaScript from https://static.klaviyo.com/onsite/js/klaviyo.js?company_id=XXXXXX (the script tag is loaded at runtime to provide tracking functionality), which constitutes executing remote code as part of the integration.
