MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).

• Third-party content exposure detected (high risk: 0.90). The skill's workflow explicitly requires fetching test-case data from Tuist (e.g., "tuist test case show --json" and the example URL https://tuist.dev/{account}/{project}/tests/test-cases/{id}) and instructs the agent to read failures[].message and source file contents to determine fixes, which ingests untrusted/user-generated third-party test run content that can materially influence follow-up actions.
