The Cabinet
Know what is in the room
An AI agent is software that does work on its own: it reads what arrives, consults, decides, and acts, within rules you set. Most are sold as magic. The Cabinet is a room, not a piece of furniture: ArkOne's reference design for an executive agent, with one voice at the head, a table of specialists, and a signature only a person may give. Eleven ordinary parts make up the anatomy, five more fixtures run the working day, and every one of them is on this floor plan.

01
One voice. Eleven parts. No mystery
A chief executive can learn the whole design in an afternoon. Each part is one job, one setting, and one question to ask anyone selling you an agent.
1The Chair
the orchestrator
Runs the room. One voice for the whole company.
A loop that runs a bounded number of times, then the meeting ends.
Ask the vendor: How many times can it go around before it must answer me?
Read the paper
2The Table
parallel consultation
Who is in the room and how they are called, in parallel.
Specialists consulted side by side, never one long queue.
Ask the vendor: How many specialists can it consult at once, and what stops it consulting all of them every time?
Read the paper
3The Seats
the specialist agents
Ten specialists: Strategy, Finance, Counsel, People, Operations, Marketing, Product, Board, Talent, Triage.
Each one is a name, a model and a set of instructions.
Ask the vendor: Can I change a specialist’s instructions without a redeploy?
Read the paper
4The Brief
the standing instructions
What the Chair reads before every turn.
The order matters: the parts that never change are cached, and a cached read is billed at a fraction of a fresh one.
Ask the vendor: What is in the part of the prompt that never changes, and what is in the part that does?
Read the paper
5The Library
the knowledge base
Four shelves, kept apart on purpose.
House knowledge, the client’s documents, recorded failures, recent research.
Ask the vendor: What decides whether a document it found is relevant enough to use?
Read the paper
6The Minutes
the memory
What was decided, written after the meeting, read back next time.
The room remembers nothing; it reads the Minutes.
Ask the vendor: Where does what it remembers live, and can I read it?
Read the paper
7The Clock
the scheduler
Acts when nobody asked.
A job is claimed in one indivisible step, so it fires once and only once.
Ask the vendor: What can it do at three in the morning with nobody watching?
Read the paper
8The Door
the outbound guardrails
What may leave the room, to whom, and when.
Rules in code the model cannot argue with, and a reason returned when it refuses.
Ask the vendor: What sits between the model deciding to message someone and the message leaving?
Read the paper
9The Signature
the human approval step
A step that waits for a person.
The run records the decision and stops; a person restarts it.
Ask the vendor: Which actions wait for a human, and what happens when the human is slow?
Read the paper
10The Record
the audit log
Every action, with its stated reason.
An audit trail that can never block the meeting.
Ask the vendor: Show me the record of the last thing it did, and why.
Read the paper
11The Switchboard
model routing
Which model answers which call.
Chosen per call, so one meeting can draw on several providers and owes none of them loyalty.
Ask the vendor: Which model answers which kind of question, and who decided?
Read the paperWhen the room goes to work
The eleven parts are the anatomy. A working day needs five fixtures besides, and one standing examination.
The Mandate
the autonomy levels
What each Seat may do without asking: act, propose, or escalate.
Read the paperThe Directory
the approved-contact list
The people the Cabinet knows: who it may address, who may approve what.
Read the paperThe Order Paper
multi-step deliverables
Set-piece deliverables, run to a plan the reader sees before the work.
Read the paperThe Morning Box
the daily digest
What the room hands the chief executive at eight and at close of day.
Read the paperThe Rehearsal
the evaluation suite
How the design is examined before it meets your company, and after every change.

What lands on your desk
The room's output is a short morning brief of decisions already worked, each one waiting for a word from you. Suppose it is a Tuesday. Answer the three items and watch what each one was holding back:
The Morning Box
Illustrative: invented company and numbersTuesday, 07:58 · 3 of 3 waiting for you
Hold the list price on the renewal
They asked to renew at last year's price. Finance sized the margin and Marketing checked the story: offer the volume tier instead. The reply is drafted.
One payment reminder is held at the Signature
Two invoices sit past forty-five days. The first reminder went out yesterday; the second waits for your word before it leaves.
A competitor changed their published prices overnight
The Watch flagged it at 03:10, sized it against this quarter's goals, and filed the briefing in the Record.
The Record
append only · a correction is a new entry, never an edit
- 03:10Watch raised one alarm: competitor published prices changed. Briefing filed.
- 06:41Finance Seat proposed holding list price on the renewal. Held for approval.
- 07:52Second payment reminder reached the Signature. Waiting for a person.
A composite morning, and the three items answer. Each one names the setting that governs it, and every decision you take writes a line to the Record that cannot be taken back.
