[gotcha] AI agents with excessive autonomy take irreversible actions users never explicitly authorized

Implement explicit confirmation steps before any irreversible action \(delete, send, purchase, deploy\). Scope AI permissions to the minimum necessary — follow principle of least privilege for tool access. Never give AI agents write/delete/execute permissions without human-in-the-loop confirmation. Always provide undo capability for AI-initiated actions.

Journey Context:
The temptation when building AI agents is to give them broad capabilities so they can 'handle anything the user asks.' But this creates a UX disaster: the AI takes actions the user did not intend, cannot undo, and did not explicitly confirm. A classic pattern: an AI email assistant reads a message about a scheduling conflict and automatically sends a decline, or an AI coding agent deletes files it considers unnecessary. The OWASP LLM Top 10 calls this Excessive Agency \(LLM06\) — the system allows the LLM to perform more actions than necessary for its intended function. The gotcha is that excessive agency feels great in demos \(look, it just works\!\) but fails catastrophically in production where edge cases and misinterpretations are common. The fix is architectural, not prompt-level: limit tool access at the permissions layer, require confirmation for destructive actions, and always provide undo. A system prompt saying 'ask before acting' is insufficient — the model will sometimes decide an action is safe enough to skip confirmation.
