Low-risk findings.
2 low severity findings. Worth noting, but not necessarily harmful.
W011: Third-party content exposure detected (indirect prompt injection risk).
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
Runtime workflow: plugin HTTP API route handlers defined via `definePlugin({ routes })` ingest request bodies/query parameters through `ctx.input` (e.g., `routes: { ... handler: async (ctx) => { const { ... } = ctx.input; } }`), meaning outsider-authored free text can be posted to the endpoints.
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 hooks example returns an external-script contribution that will be fetched and executed at runtime in users' browsers (src: https://www.googletagmanager.com/gtm.js?id=GTM-XXXXX) and includes a noscript iframe (https://www.googletagmanager.com/ns.html?id=GTM-XXXXX), which are runtime external resources that execute remote code.
