Agents & AI

Agents draft, route, and propose well. They absorb blame poorly. I design for that asymmetry before the first irreversible action — not after the incident bridge.

Autonomy is a feature. Unattended autonomy is a liability. A careful colleague must still be able to interrupt, explain, and reverse.

Failure modes I design for
  • Money move. An agent queues a transfer. Who confirms? Is the confirm logged with a name, not a shared bot token?
  • Health tip. A suggestion sounds confident and is wrong. Can a clinician override in one honest click?
  • Public statement. Draft goes out under a brand. Who owned the nod before publish?
  • Silent loop. Tool calls keep retrying at 2 a.m. Does anyone get paged before harm compounds?
  • Eval theatre. A launch checklist passes once. Continuous eval would have caught the drift.
The override click

Good agent stacks are not the ones that talk longest. They are the ones where:

  • mandate is explicit — what the agent may do without asking;
  • high-stakes steps have a named human checkpoint;
  • override is one honest click, and the override is logged;
  • traces answer “what did it try, and who approved next?” without a scavenger hunt.

“A demo that cannot say who owns the next decision is unfinished work.”

That is the bar I use when choosing tools, vendors, and architecture.
