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
[resources/known_consumers.md + downstream consumer checkouts under this skill’s required runtime workflow describe locating and modifying external downstream repositories (and running their dependency resolution/tests), which implies the LLM can ingest outsider-authored free text from those repositories’ files (e.g., code, tests, and possibly failure output) rather than only first-party documentation.]
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 instructs updating a consumer's pubspec to point at the git URL https://github.com/flutter/agent-plugins and to run dependency resolution/tests, which causes runtime fetching and execution of remote code from that repository.
