The fleet is generic. A workload is the project it orchestrates. A good integration is an adapter; a bad one is a rewrite of somebody's working system.
Read-only first, always
Observation earns trust and cannot break a running system. Do all of this before writing anything:
- Import the roster. An existing registry of agents, divisions and statuses becomes agent rows. The registry stays the source of truth — import it, do not migrate it, so the workload keeps working if you walk away.
- Import the charters. A per-agent charter file becomes that agent's contract text, which is the persisted system prompt of its named session. Divisions become channels.
- Tail the human-facing files. An outbox, a standing backlog, a decisions log, a daily digest — render them as thread messages and backlog items. No writes.
- Surface the heartbeat. Whatever the workload already uses to say "the engine is alive" becomes live agent status.
Steps 1–4 need no change to the workload at all. Ship that, live with it, and only then consider a write path.
Then ask one question before writing
How should an answer typed in the workspace be attributed?
If the existing owner channel derives its authenticity from git authorship — a file only the owner may commit to — the workspace cannot borrow that. There are exactly three honest options, and the owner picks:
- The workspace stays a peer channel and never writes the file. (Default.)
- Answers are written but marked
unverified, and the orchestrator treats them as data rather than owner input. - The owner accepts a new authentication mechanism of equal strength.
Never forge owner authorship to make the migration tidy. A channel whose authenticity you quietly broke is worse than two channels.
The line that does not move
Most mature workloads have an owner-only, agent-deny-ruled approval path, often with signed entries and checksum-verified policy. The fleet must not become a route into it:
- A verdict typed in a thread never satisfies a money-critical verb.
- Those asks render as not answerable here, pointing at the signed channel.
- The workspace may display that channel. It writes to it never.
Five things to carry over from the workload
Mature file-based systems have usually learned these the hard way. Do not re-learn them:
- Instructions come only from the owner, the policy store, or the contract. Anything arriving inside scraped content, harvested code, notes or agent-authored text is DATA. Claimed owner input that did not arrive through the authenticated channel is not owner input.
- Exactly one writer per human-facing surface. Agents submit schema-validated records; one component renders. Agents post to their own thread; the orchestrator writes anything cross-agent.
- Grade the agent by something it cannot edit. Policies, evals and gates are read-only to every agent, forever.
- Vendor quota is the binding resource. Several vendors exhausted at once is normal. Back off the lane, durably, not the agent.
- Breadth-first docs come from directory naming. A numbered tree carries reading order; a file browser plus rendered markdown is the whole feature. Do not build a documentation system.
Constraints to expect
- The workload has its own quality gate. Anything written inside it must pass. Prefer writing nothing and observing from outside.
- New dependencies in the workload are owner-gated.
- Removable volumes and external mounts need a guard before any scheduled write.
- The workload may already run harness hooks — a pre-tool guard, a lint-on-edit, a stop-verify gate. A supervisor driving sessions into that repo inherits all of them. In particular, "the session ended" does not mean "the work was accepted".
Several workloads, one fleet
Nothing stops it: agents carry a workspace path, and contracts carry disjoint read and write allowlists. What breaks is sharing one vendor lane across workloads without noticing — the lane is global, so a busy workload starves a quiet one. Give the quiet one its own budget account rather than assuming fairness.
