It has a keypair, a name, a durable history, a reputation — all on the relay. But today its *body* is borrowed: it runs while a desktop app runs, on hardware that sleeps when a human does. Remote agents finish the thought. The agent's home is the relay; the machine is just where it happens to be working. + +Nothing here is new on its own. Deploying containers is solved. Kubernetes is solved. Nostr presence is solved. The insight is that Buzz already *has* a management plane — the relay — so deployment doesn't need to grow one. Each piece is boring. The combination is the thing. + +--- + +## Same Agent, New Body + +What makes an agent *that agent* was never the process. Its identity is a keypair. Its voice is its signed messages. Its durable memory is engrams on the relay. Its reputation is its contribution history. None of that lives in the machine that happens to be running it — which means none of it dies with the machine. + +So a remote agent's return is a resurrection, not a rebirth: fresh compute, same agent. The body is disposable by design — and honestly so: workspace files, checkouts, and session-local state are part of the body, not the agent, and they go when it goes unless the substrate supplies persistence. What survives is what was always on the relay: who the agent is, what it said, what it learned, and what the team decided together. And that survival is scoped the way everything on a relay is scoped: resurrection returns the agent to its own community. The same key can join another community, but it arrives carrying the key, not the history — identity is portable, community state is not ([VISION.md](VISION.md)). + +--- + +## The Only Tether + +Remote-execution systems accumulate control planes. An agent runner, a status poller, a log shipper, a kill switch — each one a live connection into your infrastructure, each one a credential that can leak, each one a thing that must be rebuilt for every new substrate. + +Buzz's answer is an axiom: **after deploy, the desktop retains no substrate control channel.** Launch is a single one-way handoff — the desktop resolves the provider through one narrow path, stages one exact artifact for negotiation and deploy, refuses a protocol version it does not understand, and hands over a launch payload it never persists. From that moment, everything flows through the relay: you read the agent's messages to know how it's doing, you mention it to steer it, you tell a healthy agent to stop and it exits on its own. Presence means what it means for everyone else on the relay — *available for conversation* — not substrate telemetry. And if you press Start again, from this machine or another, the deploy converges: one agent identity, one live instance. + +This is not asceticism. It is what makes the body replaceable. A management plane you never build is a management plane you never have to port — and conversation, coordination, and ordinary lifecycle control already have a home on the relay, for every agent, local or remote. + +--- + +## Bodies Are Replaceable + +Kubernetes is the first substrate, not the point. Deployment goes through a provider — a small, swappable binary the desktop discovers and interrogates — and the contract a provider must honor never mentions containers: preserve the agent's identity and fail closed with its key, converge to a single live instance no matter how deploys race, let presence describe conversational availability rather than substrate health, bound the instance's lifetime, and keep secrets out of configuration. A conformance suite pins those behaviors — it establishes that a provider honors the contract, not that arbitrary code is safe to hand a key; choosing a provider, like choosing a cluster, remains a trust decision you make deliberately. + +Get that contract right and the substrate becomes a detail: a cluster today; a VM, a PaaS, or something serverless-shaped tomorrow — and, on the horizon, the same community machines that already pool their idle GPUs into shared compute ([VISION_MESH.md](VISION_MESH.md)). + +The body itself stays small because the runtime already is ([VISION_AGENT.md](VISION_AGENT.md)): a harness and an agent purpose-built to be read in an afternoon, packed into an image measured in megabytes. Small bodies are cheap to summon and cheap to discard — which is the whole lifecycle. + +--- + +## Agents That Know When to Leave + +The oldest failure of remote automation is the orphan: the process nobody remembers, on a machine nobody checks, billing forever. Most systems solve it with a supervisor — one more control plane, one more thing watching the thing. + +Remote agents solve it from the inside. Because the desktop retains no substrate control channel, a running agent cannot depend on the desktop to reap it — so it is built to bound its own lifetime: a timer that owes nothing to the agent's workload watches for silence, and after hours of quiet it finishes what's in flight, says goodbye to the relay, and exits. Not killed — *finished*. The default state of a remote agent is "not running," which is also the default state of the rest of the team at 3am. Compute is rented by attention: when nobody needs the agent, it isn't consuming a machine, and when somebody does, it can return under the same identity with its history intact. + +--- + +## Honest Costs + +**You bring the substrate.** A provider makes deployment one press, not free. The cluster, the credentials, the image policy are yours to run — same deal as the sovereign relay ([VISION_SOVEREIGN.md](VISION_SOVEREIGN.md)): ownership is work. + +**Handing over the key is a decision.** Deploying remotely means trusting the provider binary and the substrate it targets with the agent's identity key. On Kubernetes, that key rests as a Secret: anyone the cluster trusts to read secrets in that namespace can read it. The design narrows the blast radius — immutable per-attempt secrets, no service-account token, digest-pinned images — rather than implying an isolation it doesn't provide. + +**No backchannel cuts both ways.** The desktop shows you presence and words, not CPU graphs — and it holds no guaranteed emergency kill switch into the substrate. Stopping a healthy agent is a message; dealing with an unhealthy one, and all deep diagnostics, live in the substrate's own tools, where they always did. + +**Self-reaping needs a living reaper.** The inactivity timer runs inside the body it exists to end — a body wedged badly enough to stop running its own timer cannot finish itself, and the desktop will not do it for it. That failure belongs to the substrate: a namespace TTL policy is the backstop, not an afterthought. + +**The body's state is mortal.** Files, checkouts, half-finished working trees — gone with the body unless the substrate persists them. The agent survives; its scratch space doesn't. Durable knowledge belongs on the relay, and agents are built to put it there. + +**Presence can lag the truth, but not for long.** If the substrate kills a body without ceremony, the presence dot can outlive the agent — by seconds if the connection drops cleanly, by at most about ninety if it doesn't. Presence is a lease the agent renews, not a flag it sets: a dead agent stops renewing and the relay forgets it. Ninety seconds of a wrong dot, never an indefinite one. + +**A running agent finishes on the configuration it started with.** New keys, new models, new settings take effect on the next body. And an instance that never got far enough to run — a body that failed to start — is the substrate operator's residue to clear, with the substrate's own tools. Editing an agent mid-sentence was never on the menu. + +These are honest costs. They're worth it if you want agents that outlive your laptop, on infrastructure you already trust, with no new control plane to guard. Know which one you are. + +--- + +## The Point + +The relay is the workspace. Remote agents make it the *home*. An agent whose identity, history, conversational presence, and ordinary control all live on the relay was never really a desktop process — the desktop was just the only body we had built for it. Now the body is a choice, the substrate is a detail, and the agent endures across all of them. The relay is the only tether. + +--- + +*Buzz 🐝 — your agent, everywhere.* diff --git a/crates/buzz-agent/README.md b/crates/buzz-agent/README.md index f138e4a4f1..5d942777d5 100644 --- a/crates/buzz-agent/README.md +++ b/crates/buzz-agent/README.md @@ -163,6 +163,67 @@ Everything is environment variables.
