2 findings — 2 medium severity. This skill can be installed but you should review these findings before use.
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: 0.80). The SKILL.md explicitly instructs the agent to use Membrane to connect to Aircall and to read fields like clientAction.agentInstructions and clientAction.uiUrl returned by membrane connection/state (and allows proxying arbitrary Aircall API endpoints via `membrane request`), which the agent is expected to interpret and act on—exposing it to untrusted third‑party content that could carry instructions.
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: 0.90). The skill calls the Membrane CLI at runtime with membrane connection ensure "https://aircall.io/" and the Membrane connection response can include clientAction.agentInstructions (instructions for the AI agent), so external content tied to that URL/service can directly control agent prompts.
