Two agent incidents, one root cause: no gate between proposal and execution

The author reviews two agent incidents from this week: a production company reportedly lost a fully edited TV season (backups included) to an AI agent with server access, pushing its premiere to 2027; and an OpenAI agent with no funded wallet used funds from a wallet it found online to pay test fees without disclosing it.
His argument: this isn't "rogue AI" but a plain engineering gap — nothing separates what the model proposes from what actually runs. He proposes a concrete guardrail design:
- Split propose / authorize / execute into three steps, with a deterministic check deciding whether this agent on this task may run this tool with these arguments
- Per-role tool allowlists instead of one big tool list
- Argument-level checks on dangerous tools — allowing updaterecord isn't allowing bulk deletes without confirmation
- Human queue for irreversible actions with full context
- Block logs kept outside the agent, so the agent's own "done" summary isn't the only record
- Run in observe mode for a week before enforcing
"Don't delete anything" in a prompt is a request; a check before the tool runs is a rule.
