MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 1.00). The webhook example uses the runtime URL "https://api.acme.com/crm/lookup", which Patter POSTs to during calls and injects the returned JSON as the tool result into the agent's context (directly controlling agent outputs), so this is a runtime external dependency that can control prompts.
