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's SKILL.md and scripts/context7_cli.py explicitly call Context7's query_docs/resolve_library_id to retrieve documentation and code examples (including source URLs like GitHub) and even instructs using a web fetch to retrieve full content, which means the agent will ingest and act on untrusted public third‑party content.

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 the external MCP endpoint https://mcp.context7.com/mcp at runtime (via StreamableHttpTransport) to fetch documentation snippets that are returned and injected into agent responses (thereby directly influencing prompts/instructions), and the skill requires that external service (and an API key) to function.
