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: 1.00). The SKILL.md explicitly instructs the agent to use the web_search_exa tool to fetch code snippets and documentation from public third-party sources such as GitHub and StackOverflow, and to read/interpret those results as part of its workflow (extracting and acting on snippets), which exposes the agent to untrusted, user-generated content that could carry indirect prompt-injection 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's MCP configuration calls the external endpoint https://mcp.exa.ai/mcp?tools=web_search_exa at runtime to fetch search results/snippets that are injected into the agent's context (used to form responses and code examples), so the fetched content can directly control prompts and deliver executable code.
