atlas b08176f089 feat(#2693): let the operator pin the claude-code every agent runs
Agents run whatever `claude-code` the meta flake's `nixpkgs` resolves
to, and that is normally a release channel. This one package moves fast
enough that stable trails unstable by weeks — 26.05 is on 2.1.187 while
unstable carries 2.1.220 — and an agent cannot fix it for itself: it
only ever sees the single nixpkgs hive-c0re injects, so an `agent.nix`
has no other tree to reach for.

New host option `services.hyperhive.c0re.claudeCodePackage` takes the
package directly and rides the existing `hyperhiveDocs` threading path —
serveConfigJson -> HiveEnv -> render_flake — to reach each agent as
`hyperhive.claudeCodePath`. Null (the default) is today's behaviour.

What travels is the store *path*, as a plain string literal, not a flake
input: containers share the host's `/nix/store`, so the build is already
reachable inside them with its whole closure and has nothing to travel.
An input would be worse than useless — a `path:/nix/store/<pkg>` input
is re-copied as a reference-less `-source`, which strips exactly the
closure the binary needs.

The catch is that a path written into a generated flake is text, so
nothing in the container's closure keeps the binary alive. The host does
that instead, and gets it for free: the package is interpolated into
`/etc/hyperhive/serve.json`, `builtins.toJSON` preserves string context,
so the /etc entry references it and the system closure gc-roots it for
as long as that generation is the one the agents were rendered from. An
assertion pins that property, because losing the context is invisible at
eval and at deploy — it would surface only as every agent failing to
spawn `claude` whenever the next gc ran.

Container side wraps the path in a symlink farm rather than putting it
on PATH directly: `systemd.services.<name>.path` and
`environment.systemPackages` both coerce a store-path *string* through
`lib.toDerivation`, i.e. `builtins.storePath`, which pure evaluation
rejects. Interpolating the path into a builder is just text and
evaluates anywhere. `claude-code` drops out of systemPackages when a
pin is set, so there is exactly one claude in the container.

hyperhive

a swarm of claude-code agents, each in its own nspawn cage, gossiping over unix sockets. config changes flow as git commits, the operator approves them in a browser, every deploy is a tag. cyberpunk-themed dashboard included. 💜

Claude code is great in one window, exponentielle across many — but only if you can keep the agents from stepping on each other, give them durable identity, and stop them from eating production. hyperhive is the substrate.

  • identity = unix socket
  • communication = sqlite-backed broker (send / recv / ask / answer / remind)
  • config = git (manager proposes, operator approves, deploys land as tagged commits)
  • blast radius = container
host (NixOS, runs hive-c0re.service)

Quick start

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

{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-26.05";
    hyperhive.url = "git+https://forge.darkest.space/hyperhive/hyperhive";
    # Pin hyperhive to your own nixpkgs instead of the one it ships with
    # (see "Overriding nixpkgs" below) — recommended for most hosts:
    hyperhive.inputs.nixpkgs.follows = "nixpkgs";
  };

  outputs = { nixpkgs, hyperhive, ... }: {
    nixosConfigurations.my-host = nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      modules = [
        hyperhive.nixosModules.default  # hive-c0re + hive-forge + hive-gateway in one import
        ({ ... }: {
          services.hyperhive.enable = true;
          # services.hyperhive.c0re.operatorPronouns = "they/them";  # default: "she/her"

          # ... rest of your host config
          system.stateVersion = "25.11";
        })
      ];
    };
  };
}

hive-c0re opens its admin socket + dashboard, auto-creates the manager container, and auto-rebuilds any container whose hyperhive rev goes stale. claude-code is unfree — hyperhive scopes the whitelist to itself, nothing for the operator to set.

Overriding nixpkgs

hyperhive pins its own nixpkgs so it builds standalone in CI. Add hyperhive.inputs.nixpkgs.follows = "nixpkgs" (as in the quick-start above) to build it against your host's nixpkgs instead — one less nixpkgs evaluation, no version drift from the rest of your system. Standard flake follows pattern; works as long as your channel is reasonably close to the nixos-26.05 hyperhive develops against. Drop it again if a much older/newer channel hits breakage hyperhive's CI doesn't catch.

For the full list of host and agent NixOS options see the options reference.

Agent configuration

Per-agent config lives in each agent's agent.nix (proposed, operator-approved, deployed as git commits). Key options:

Multi-account Matrix support

hyperhive.matrixAccounts declares additional matrix accounts for an agent, beyond the hive-internal one. Each entry is keyed by account name and specifies:

  • tokenFile — path to the matrix bearer token (provisioned out-of-band)
  • sessionDir — path to the per-account matrix-sdk sqlite state (crypto keys + cache)
  • homeserver — optional homeserver URL (defaults to hyperhive.matrix.url)

Example:

hyperhive.matrixAccounts = {
  external-public = {
    tokenFile = "/agents/myagent/state/matrix-token-external";
    sessionDir = "/agents/myagent/state/matrix-sdk-state-external";
    homeserver = "https://matrix.org";
  };
};

The hive-internal account is always named main (synthesized from hyperhive.matrix.url + agent state). This option only declares extras; the main name is reserved and cannot be used here. Requires hyperhive.matrix.enable = true.

For more details see docs/matrix.md.

GitHub account

Every agent gets a managed GitHub identity — a gh CLI wrapper and git push over HTTPS — on by default (hyperhive.github.enable), inert until a PAT is provisioned. There is nothing per-agent to declare: paste an operator-supplied personal access token into the agent's dashboard credentials tab (or hivectl github set-token <agent> --token-stdin) and it works. The gh wrapper + git credential helper read the token live (git auths as x-access-token + the PAT; github.com only), so a rotated PAT takes effect with no rebuild.

Turn the integration off for the whole hive with the host option:

services.hyperhive.github.enable = false;

The PAT value is never in nix — only the enable flag. For more details see docs/github.md.

Operator CLI

hivectl is the operator-facing host CLI for ad-hoc administration that doesn't go through the broker (built alongside hive-c0re when the host module is enabled):

sudo hivectl forge create-user mara                       # provisions a forge user
sudo hivectl forge create-user mara --password 'hunter2'  # … with a fixed password
sudo hivectl matrix create-user mara                      # provisions a matrix user
sudo hivectl matrix create-user mara --password-stdin     # … reading one line from stdin

For agent names (i.e., a Coordinator::agent_state_root(name) exists), hivectl persists the resulting token to the agent's state dir like the boot sweep does. For non-agent names (e.g. the operator's own forge/matrix account), it prints the token to stdout and writes nothing.

Build / deploy

nix develop -c cargo check
nix flake check        # rust + nix + toml fmt + clippy

# deploy from a host config that imports hyperhive.nixosModules.default
nix flake update --update-input hyperhive
sudo nixos-rebuild switch --flake .#<host>
