# hyperhive
|
||||
|
||||
Multi-Claude-Code-agent orchestration on **nixos-containers**.
|
||||
> 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. 💜⚡
|
||||
|
||||
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.
|
||||
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
|
||||
|
||||

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.
|
||||
Depth lives in [`docs/`](docs/) — pick the one matching your task:
|
||||
|
||||
Operator surface per agent: terminal-themed live tail with a textarea
|
||||
prompt; slash commands `/help` `/clear` `/cancel` `/compact`
|
||||
`/model <name>` `/new-session`; granular state badge (idle / thinking
|
||||
/ compacting / offline) with age timer + last-turn duration chip +
|
||||
model chip; cancel-turn + new-session buttons in the state row;
|
||||
sticky-bottom auto-scroll with "↓ N new" pill; event history
|
||||
backfilled on page load; collapsible inbox + collapsible journald
|
||||
viewer + collapsible `agent.nix` viewer per agent on the dashboard;
|
||||
deployed-sha chip per container (read from meta's `flake.lock`).
|
||||
|
||||
Operator surface on the dashboard itself: a terminal compose box
|
||||
under the message-flow stream — `@name` picks the recipient with
|
||||
auto-complete from the live container list, sticky across sends,
|
||||
POSTs `/op-send` which drops the message into the broker as
|
||||
`{from:"operator", to:<name>, body}`. Same shape any sub-agent
|
||||
sees as a regular inbox message.
|
||||
|
||||
Config changes flow the other way: manager edits files under
|
||||
`/agents/<name>/config/` — `agent.nix` is a plain NixOS module function
|
||||
`{ config, pkgs, lib, ... }: { ... }`, and arbitrary sibling files in
|
||||
the commit are preserved → commits → submits the sha via
|
||||
`request_apply_commit`. Hive-c0re immediately fetches that commit from
|
||||
the proposed repo into the applied repo and pins it as `proposal/<id>`
|
||||
— immutable from the manager's side from then on. Operator clicks
|
||||
◆ APPR0VE → hive-c0re fast-forwards `applied/<n>/main` to the proposal,
|
||||
runs `nix flake lock --update-input agent-<n>` against the host-wide
|
||||
meta flake at `/var/lib/hyperhive/meta/`, builds via
|
||||
`nixos-container update <c> --flake meta#<name>`, and either commits
|
||||
the lock + tags `deployed/<id>` on success or `git restore`s the lock +
|
||||
annotates `failed/<id>` with the build error + rolls back
|
||||
`applied/<n>/main` on failure. Denials leave a `denied/<id>` annotated
|
||||
tag carrying the operator's note.
|
||||
|
||||
Meta's git log is the swarm-wide deploy audit trail (one commit per
|
||||
successful deploy). Per-agent applied repos carry the tag-rich state
|
||||
machine for inside-baseball decisions. The manager sees both — proposed
|
||||
repos ship with an `applied` remote pre-wired, and `/meta/` is RO-bound
|
||||
inside the container — so `git fetch applied`,
|
||||
`git show applied/refs/tags/deployed/<id>`, `git log /meta`,
|
||||
`cat /meta/flake.lock` all just work without constructing paths by
|
||||
hand. See [`docs/approvals.md`](docs/approvals.md) for the full state
|
||||
machine + lock-flow walkthrough.
|
||||
For decisions any agent (manager or sub) needs structured signal on,
|
||||
`ask(question, options?, multi?, ttl_seconds?, to?)` queues a question:
|
||||
default recipient is the operator (dashboard renders a free-text /
|
||||
checkbox / radio form), or pass `to: "<agent>"` to route a structured
|
||||
peer question into another agent's inbox. The answer arrives later as
|
||||
a `HelperEvent::QuestionAnswered { id, question, answer, answerer }`
|
||||
in the asker's inbox. Peer recipients respond via `answer(id, answer)`.

hive-c0re opens its admin socket + dashboard, auto-creates the

## 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
|
||||
nix flake check # rust + nix + toml fmt + clippy
|
||||
|
||||
# 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>
|
||||
# deploy from a host config that imports hyperhive.nixosModules.hive-c0re
|

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.

- **Multi-agent restart coordination**: when rebuilding all agents, manager should start first so it can coordinate post-restart confusion (notify agents, suppress unnecessary retries, etc)
|
||||
- **Shared docs/skills repo (RO)**: a single repo on the hive forge that every agent has read-only access to — common references, prompts, runbooks, "skills" the operator wants every agent to inherit without baking into the system prompt or `/shared`. Implementation likely: seed an `org-shared/docs` repo on first hive-forge boot, grant every per-agent user a read membership in the org. Agents `git clone` it (or use the API) to read; only the manager + operator can push.
|
||||
- **Loose-ends tracker + `get_open_threads` tool**: hive-c0re already knows about pending approvals + unanswered questions; soon will also know about open PRs on hive-forge. Aggregate these into a per-agent "open threads" view (e.g. `[{kind: "approval", id: 7, summary: "spawn alice"}, {kind: "question", id: 12, asker: "alice", summary: "deploy now?"}]`). New MCP tool `mcp__hyperhive__get_open_threads` returns the list so an agent can see what's still pending against it without rebuilding context from inbox history. Manager's version includes hive-wide threads. **Also surface this list on the per-agent web UI** so the operator can see at a glance what each agent has hanging open — same data source as the MCP tool, just rendered into the existing per-agent dashboard page (next to inbox view / model chip / etc).
|
||||
- **Scope per agent X (confirmed with operator):** include BOTH (a) unanswered questions where `asker == X` (X is waiting on someone) AND (b) unanswered questions where `target == X` (X owes an answer). Distinguish via a `role: "asker" | "target"` field on the question variant so the agent can render "waiting on" vs "owe a reply" appropriately. Approvals: include rows where the submitter is X (waiting on the operator). Forge PRs (future): include open PRs where X is author OR reviewer.
|
||||
- **Wire shape sketch:** new `AgentRequest::GetOpenThreads` / `ManagerRequest::GetOpenThreads` returning `Response::OpenThreads { threads: Vec<OpenThread> }` with `OpenThread` as a tagged enum (`{kind: "approval", id, summary, age_seconds}` / `{kind: "question", id, role, counterparty, summary, age_seconds}` / future `{kind: "pr", ...}`). Manager flavour returns hive-wide threads (no asker/target filter). MCP tool `get_open_threads` takes no args.
|
||||
- **Aggregator location:** new helper on `Coordinator` (or a dedicated `open_threads.rs`) so both surfaces share the query logic; queries `approvals` + `operator_questions` tables with a single per-call sweep (no caching — call frequency is low).
