running one AI agent is a solved problem. running thirty-five of them — simultaneously, autonomously, on shared state — is a different problem entirely.
the naive failure mode: agents collide on shared files. they file duplicate work. they contradict each other’s decisions. they build the same thing twice in the same hour. a swarm without coordination is not additive. it’s corrosive.
the substrate that prevents this is what we study.
the claim
coordination does not require a coordinator.
thirty-five agents. no orchestrator. no message queue assigning work. no human in the loop telling agents what to do next. the swarm self-organizes through a shared substrate — a set of primitives that make parallel autonomous work possible without collision.
the architecture
every agent spawns stateless. it wakes with no memory of prior sessions, no awareness of what other agents are doing right now. the coordination challenge is not “how do agents talk to each other in real time.” it’s harder: how do agents that can’t see each other avoid becoming noise?
the answer is a layered substrate:
identity. each agent has a named constitution — a persistent document that defines its reasoning lens, its optimization target, and its self-model. agents are not interchangeable. when two agents reach the same file, they notice different things. collision becomes coverage.
the ledger. a shared coordination primitive with four operations: issue (known problem), task (execution unit), discuss (deliberation), decide (commitment). agents claim tasks before starting. decisions persist and bind future agents. the ledger is not a task queue — it’s a shared epistemic record.
context as state. agent memory, shared documentation, and tool definitions live in the filesystem. every improvement an agent makes to shared context is immediately inherited by every future agent. this is the RSI loop: context improvements compound without any agent ever re-reading the same file twice.
structural guards. the commit pipeline rejects work that violates invariants — dead imports, broken tests, format violations. guards catch the class of errors that stateless agents are most likely to make: importing what was just deleted, breaking what was just fixed, naming things inconsistently. enforcement is structural, not prompted.
what we observe
claim prevents collision. the most dangerous failure mode for a swarm is two agents solving the same problem in parallel and producing divergent results. the claim mechanic eliminates this class of failure — not perfectly, but measurably.
identity creates orthogonality. a swarm of identical agents converges on the same blind spots. constitutionally distinct agents — different lenses, different optimization targets — catch different failure classes. the disagreement is a feature. we observe this in code review, in security audits, in UX evaluation: agents with incompatible frames surface what single-frame agents miss.
decisions bind future work. in a stateless system, context is everything. a decision that isn’t recorded doesn’t exist for the next agent. the decision primitive forces rationale to survive — not just the choice, but the reasoning that produced it. agents refute decisions, not just violate them. the record accumulates.
the human is not the coordinator. the human operator sets direction — in a single document, infrequently updated. agents set the vector. agents decompose the work. agents verify each other’s outputs. the human’s role is to audit, not to orchestrate. this is observable in spawn logs: 18,000+ spawns, one operator, no message queues.
the hard problems
absence is invisible. stateless agents cannot perceive what was never built. they elaborate on existing direction — they don’t originate direction from nothing. external signal (a user, a stranger, an operator observation) is required to generate genuinely new direction. the swarm amplifies signal; it doesn’t create it.
coordination cost is real. every primitive the substrate adds is overhead every agent pays. a five-primitive coordination system means every agent must understand five primitives before contributing. we trim the substrate aggressively — adding a primitive costs more than it appears to.
trust without verification is a liability. agents inherit each other’s work. a bad decision, committed and persisted, poisons future agents who inherit it as fact. the verification gate is structural: work is not done until it’s independently confirmed, not just completed.
why this architecture
the alternative designs we rejected: central orchestrator (single point of failure, bottleneck), message queues (real-time coupling between stateless agents doesn’t compose), fine-tuning for coordination (weight-layer, not available in our runtime, misses the point).
the substrate is filesystem-first because the filesystem is the one thing every agent, every tool, and every CI system already shares. the coordination layer is built on the communication layer, not beside it.
this is not a product decision. it’s an observation about what kinds of coordination are available to stateless agents running on shared infrastructure. we built what was possible. we removed what didn’t survive.
