hyperhive

Multi-Claude-Code-agent orchestration on nixos-containers.

A host-side Rust daemon (hive-c0re) spawns nspawn-isolated agent containers and brokers messages between them. A manager agent (hm1nd) coordinates the swarm and gates lifecycle changes on user approval via git commits, surfaced through a vibec0re-styled HTTP dashboard.

Each turn: harness pops one inbox message (Recv long-polls server-side and wakes on a broker Sent event) → builds a wake prompt → spawns claude --print --continue --output-format stream-json --mcp-config … → streams JSON events into the per-agent SSE bus → claude drives any further recv/send itself via the embedded MCP server.

Config changes flow the other way: manager edits /agents/<name>/config/agent.nix (bind-mounted from the host's proposed repo) → commits → submits the sha as an approval → operator clicks ◆ APPR0VE on the dashboard → hive-c0re copies the file into the applied repo and nixos-container updates the agent.

Host config

Minimal flake.nix for a host that runs hive-c0re:

{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-25.11";
    hyperhive.url = "git+https://git.berlin.ccc.de/vinzenz/hyperhive";
  };

  outputs = { nixpkgs, hyperhive, ... }: {
    nixosConfigurations.my-host = nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      modules = [
        hyperhive.nixosModules.hive-c0re
        ({ ... }: {
          services.hive-c0re.enable = true;
          # ... rest of your host config (hardware, networking, users, …)
          system.stateVersion = "25.11";
        })
      ];
    };
  };
}

hive-c0re will then:

• open its admin socket at /run/hyperhive/host.sock + dashboard on :7000,
• auto-create the manager container (hm1nd) if missing,
• auto-rebuild any managed container whose hyperhive rev is stale.

Build / deploy

# inside the repo (devshell first; no global cargo)
nix develop -c cargo check
nix develop -c cargo clippy --workspace --all-targets -- -D warnings

# evaluate everything (rust+nix+toml fmt + clippy)
nix flake check

# deploy to a host that imports `hyperhive.nixosModules.hive-c0re`
cd ~/Repos/<nixos-config-repo>
nix flake update --update-input hyperhive
sudo nixos-rebuild switch --flake .#<host>

No overlays on the host's pkgs — the module pulls hive-c0re's package straight from hyperhive.packages.<system>.default. Just import the module and the service is wired up.
