If you let an AI agent touch production, your first agent-caused incident isn't a question of
if — only of which quarter. The agent won't be malicious. It will be confidently, plausibly wrong:
a misunderstood instruction, a stale assumption, an API that changed last week. And it will fail
the way all incidents fail: quietly, then all at once.
Enterprise teams answer this with guardrails frameworks, policy engines, and eval suites. A team
of five has none of that — and doesn't need it. What it needs is five written answers, decided
in daylight, that any responder can execute when the agent does something expensive, weird, or
loud at 2am.
The five-line agent card
1. The kill switch — one command, tested. Not "pause the workflow." The exact CLI, the exact
dashboard toggle, the exact kill command, with the credential that runs it. If the answer is "ask
the person who built it," you don't have a card, you have a dependency on one person's sleep.
2. The blast radius — what it can touch, written down. Which systems can the agent read?
Write? Spend? List them with real names. Every unwritten permission is a permission someone will
discover during the incident instead of before it.
3. The tripwire — what "wrong" looks like in numbers. Agent incidents rarely alert. Pick two:
cost per day, error rate, output volume. When one crosses, the agent's privileges pause and a
human reviews. Without thresholds, you find out from the invoice.
4. The comms sentence — pre-written. "We identified unusual activity from an automated system
at [time], paused it at [time], and are reviewing impact." One sentence, owned by one role, sent
within 30 minutes. The first agent incident is also a trust incident; silence costs more than the bug.
5. The rollback question — decided in daylight. "If the agent misbehaves, do we revert its
last actions, disable it, or fix forward?" Three choices; pick one now. You cannot make that
decision well mid-incident, and the agent's logs won't always help you undo cleanly.
Why this beats guardrails (for now)
Guardrail frameworks assume you have an ML platform team. The five-line card assumes you have a
group chat and one brave person. It's the same argument as every small-team incident process:
the decisions were easy to make calmly, in daylight, with the docs open. Write them down where
the 2am version of your team can find them — because tired humans plus an unpredictable agent
is exactly the combination your enterprise-style review board assumed would never happen.
Then drill it once: give the agent a harmless wrong instruction and watch who notices, who runs
the kill command, and who sends the message. The gaps you find in twenty minutes are the ones
that would have cost you a week.
If you want the pre-written version, the operator's playbook — with the card, the comms templates,
and the drills — is here: Agent Ops 24/7 ($19).
The underlying IR card is free: The First 30 Minutes.
