I run AI agent teams on my own laptop, under written rules. The decisions that matter stay with me

How it is governed

27 years in investment technology

  1. 1998Wrote the code
  2. 2005Supported the users
  3. 2014Owned the product
  4. 2018Ran it as a service
  5. 2023 · NowLeads front-office transformation

Every decision goes through five questions, in order

  1. 1Is there a standing approval on file?Do it and log it
  2. 2Is it inside the team's mandate and reversible?The team decides and says so
  3. 3Is it inside the Chief's delegation?The Chief decides and tells me in its brief
  4. 4Can only I do it (pay, sign, send, supply a fact)?It becomes an errand for me, not a question
  5. 5Anything elseAn exception report with options, a recommendation and a default.

What it does for me

I speak to one coordinating session, the Chief of Staff. It passes my words to the team that owns the work. The team then does the research, drafting or building. I get a record I can read and a short list of decisions that are mine.

The test: does it take work off my desk without taking decisions off my desk?

What stays with me

The AI does the work; I make the decisions. Anything involving money, legal matters or a message going out waits for me.

  • Creating a team or changing its charter
  • Giving a team access to my mail
  • Anything for an outside audience
  • Sending, paying, signing and publishing

Agents draft. I read and send.

What went wrong, and what it cost

The full account
  • 16 October 2026 Stopped

    My first mail assistant was too fast: a single sender list would have moved dozens of priority mails. I stopped that team until a review.

  • The same evening Stopped

    I stopped the software engineering team, for over-engineering and for running too long. Builds now come only from a specification an analyst team has written and challenged first.

  • The cost No saving shown yet

    Reading one mail properly cost about 3,100 tokens. I cannot yet show a saving, and will not claim one.
