Low-risk findings.

2 low severity findings. Worth noting, but not necessarily harmful.

Low

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

The skill ingests outsider-authored free text from the user’s conversation (“Pasted text”) and may also ingest fetched API documentation text during auto-discovery via `WebSearch` + `WebFetch` when upgrading Minimal→Full based on a user-provided host (free-form host trigger).

Low

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 explicitly instructs the agent to run WebSearch/WebFetch at runtime to fetch API documentation (e.g., api.openai.com) and then parse those fetched docs to build endpoint inventories that directly drive generated policy content, so external documentation pages are runtime dependencies that control the agent's behavior.
