model persistence: /model <name> now writes to /state/hyperhive-model (in-container), Bus::new reads it on init. operator override survives harness restart and container rebuild; gone on --purge like every other piece of agent state. path overridable via HYPERHIVE_MODEL_FILE for tests. failure to persist is a warn, not fatal — runtime override still applies, just won't survive a restart. unfree opt-in: drop the auto-allowUnfreePredicate from harness-base.nix and the claude-unstable overlay. operator now has to set nixpkgs.config.allowUnfree (or a predicate listing claude-code) in their own host config. silent unfree bypass was sketchy; this is honest. readme + gotchas updated to spell out the snippet. todo: drops model-persistence + container-crash + journald (all shipped); adds per-agent send allow-list (constrain who an agent can message).

# 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.
|
|
|
|
```

|

MCP (send / recv) + web UI on a hashed :8100-8999
|
|
```
|
|
|
|
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 + a sqlite history db →
|
|
claude drives any further `recv`/`send` itself via the embedded MCP server.
|
|
|
|
Operator surface per agent: terminal-themed live tail with a textarea
|
|
prompt; slash commands `/help` `/clear` `/cancel` `/compact`; granular
|
|
state badge (idle / thinking / offline) with age timer; cancel-turn
|
|
button while thinking; sticky-bottom auto-scroll with "↓ N new" pill;
|
|
event history backfilled on page load.
|
|
|
|
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 update`s the agent.
|
|
For decisions the manager needs human signal on, `ask_operator(question,
|
|
options?, multi?)` queues a free-text/checkbox/radio form on the
|
|
dashboard; the answer arrives later as a `HelperEvent::OperatorAnswered`
|
|
in the manager's inbox.
|
|
|
|
## Host config
|
|
|
|
Minimal `flake.nix` for a host that runs hive-c0re:
|
|
|
|
```nix
|
|
{
|
|
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.
|
|
|
|
`claude-code` is unfree; hyperhive does not auto-allow it for you.
|
|
Add to your host config:
|
|
|
|
```nix
|
|
nixpkgs.config.allowUnfreePredicate =
|
|
pkg: builtins.elem (nixpkgs.lib.getName pkg) [ "claude-code" ];
|
|
```
|
|
|
|
(or `nixpkgs.config.allowUnfree = true`, your call). Each per-agent
|
|
container inherits this through the same nixpkgs evaluation.
|
|
|
|
## Build / deploy
|
|
|
|
```sh
|
|
# 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.
