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

• Third-party content exposure detected (high risk: 0.80). The SKILL.md explicitly instructs using the "Claude Anthropic Chrome extension" so Claude can "see and interact with the HubSpot workflow builder UI" (a third‑party web UI containing user-generated contact data), which the agent would read and act on as part of its workflow, creating a clear avenue for untrusted content to influence actions.
