[gotcha] Excessive agency: the LLM can invoke tools with real-world side effects

Give the LLM the smallest set of tools possible, require explicit human approval for destructive or irreversible actions, and validate tool arguments against an allow-list schema before execution.

Journey Context:
Connecting an LLM to email, shell, databases, or payment APIs turns prompt injection into account takeover or data loss. The mistake is designing 'helpful' agents with broad permissions. Least-privilege tool design and human confirmation for high-impact actions contain the blast radius.
