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
The skill's SKILL.md shows the agent using the Membrane CLI to connect to external app URLs and proxy arbitrary API requests (e.g., "membrane request CONNECTION_ID /path/to/endpoint") and to read connection-side fields like clientAction.agentInstructions and clientAction.uiUrl, which means it fetches and interprets external/untrusted third‑party content that can drive subsequent agent 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
The skill uses the Membrane CLI at runtime (e.g., `membrane connection ensure "https://www.actionbuilder.org/"` and `membrane connection get <id>`) and the returned `clientAction.agentInstructions` field from the remote service can directly provide instructions for the AI agent, so external content fetched during runtime may control agent prompts.
