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: 0.90). SKILL.md explicitly instructs the agent to call the 2markdown service via Membrane (e.g., "membrane request CONNECTION_ID /path/to/endpoint" and the connection `clientAction.agentInstructions` field), meaning the agent will fetch and programmatically act on content from a third-party web API (including user-uploaded documents and agentInstructions) that could materially influence subsequent 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 calls Membrane at runtime (e.g., `membrane connection ensure "https://2markdown.com/"` and `membrane connection get`) and the returned connection object may include clientAction.agentInstructions—remote instructions that the agent can programmatically follow—so https://2markdown.com/ is a runtime external URL that can directly control agent prompts.
