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 allows the agent to fetch and run Membrane/Ably actions and raw proxy requests (e.g., "membrane action run", "membrane request", and actions like "get-message-history" and "get-channel-presence") and also surface remote clientAction.agentInstructions and clientAction.uiUrl, which means the agent will read and act on untrusted, user-generated content from third-party Ably channels/APIs.

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 relies on the Membrane CLI at runtime (e.g., `membrane connection ensure "https://ably.com"`) and the Membrane service responses can include a `clientAction.agentInstructions` field that supplies remote, runtime-provided instructions for the AI agent, which means external content can directly control agent prompts.
