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

Third-party content exposure detected (high risk: 0.90). The skill explicitly instructs the agent to fetch and ingest a GitHub PR diff (it expects a GitHub PR URL and directs using "gh pr diff <pr>"), so it will read untrusted, user-generated third-party content from public repositories and use that content to drive review decisions and actions.

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

Potentially malicious external URL detected (high risk: 0.80). The skill explicitly requires a GitHub PR URL (https://github.com/<owner>/<repo>/pull/<n>) and calls `gh pr diff <pr>` at runtime to fetch the PR diff hunks, which are then injected into the agent's context to drive its review output, so remote content directly controls prompts.
