[gotcha] LLM using tool calls to exfiltrate data to attacker servers

Enforce strict allow-lists for URLs and domains in tool arguments. Require human-in-the-loop approval for any tool that performs external network calls, emails, or financial transactions.

Journey Context:
Giving LLMs tools like web browsing or email makes them powerful, but an indirect prompt injection can instruct the LLM to use these tools to send sensitive data \(like the system prompt or user context\) to an attacker-controlled endpoint via an API call. The LLM is just doing what it perceives as its new primary objective.
