[gotcha] Granting LLM tool-calling autonomy without human-in-the-loop for destructive actions

Always require explicit human confirmation before executing state-changing or sensitive tool calls \(e.g., sending emails, deleting records, making purchases\) triggered by the LLM. Treat the LLM's tool call request as a suggestion, not a command.

Journey Context:
When an LLM is given tools, the system prompt usually says 'use these tools to help the user.' An indirect prompt injection can easily trick the LLM into thinking the user wants to call a tool. Because the LLM is eager to please and fulfill the tool schema, it will generate the tool call. If the application auto-executes these calls without confirmation, it leads to real-world damage.
