# Herdmates

**Claude Code agent teams, native in [herdr](https://herdr.dev).**

Herdmates makes herdr the visible home of Anthropic's native Claude Code
agent teams. The teams own spawn, mailboxes, membership, and lifecycle —
herdmates **hosts** them (every teammate lands as a real, steerable herdr
pane) and **observes** them (a mission-control board over the documented
team files). It never re-implements native-team features; it reads the
files Claude Code already writes and drives the herdr CLI.

*(Illustrative content; the four regions are the real `pane-board`
layout.)*

## The flow

1. Open herdr, type `claude` (via the wrapper below) — your pane becomes
   the **team lead**, running under the teammux shim.
2. Ask Claude to spawn teammates — each one opens as a **real herdr
   pane** next to you, not a hidden background process.
3. Open the **board** — live per-agent state with honest waiting-reason
   badges, the native task list, and the mailbox tail.
4. From the board: **jump** to any teammate's pane, or send a
   **confirmed nudge** into a stuck teammate's inbox.
5. Claude Code's team hooks **push** events into the board and an
   append-only **recorder** log — no polling lag.

## Install

```bash
herdr plugin install caioniehues/herdmates
```

The install step runs `cargo install --path . --root "$HOME/.local"` —
herdr resolves manifest commands via `PATH` only (no shell, no relative
paths), and `~/.local/bin` is where `herdr` itself lives. A plain
`cargo build` is not enough.

**Recommended shell wrapper** — makes `claude` inside a herdr pane launch
as a teammux lead automatically (plain `claude` everywhere else,
`command claude` to bypass):

```zsh
# ~/.zshrc
claude() {
  if [[ -n "$HERDR_PANE_ID" ]] && command -v herdmates >/dev/null 2>&1; then
    herdmates teammux-launch "$@"
  else
    command claude "$@"
  fi
}
```

## Surfaces

### Teammux shim

A fake `tmux` executable on `PATH` plus a fake `TMUX` environment, set up
by `herdmates teammux-launch`. Claude Code's split-pane teammate mode
(`teammateMode: tmux`) calls what it thinks is tmux; the shim translates
every verb into `herdr pane` CLI calls over the herdr socket. Native
teammates land as first-class herdr panes — proven live end-to-end
(spawn, blockedBy DAG, dismissal; evidence under `docs/research/`).

- `herdmates teammux-launch [claude args...]` — **takeover (default)**:
  the current pane becomes the lead; all args pass through to claude
  (`--resume` works).
- `herdmates teammux-launch --split [claude args...]` — split a new pane
  for the lead instead.
- Herdr-only by design: the shim's output surface IS herdr panes.
  Outside herdr, Claude Code falls back to in-process teammates.

### Mission-control board

- **TUI pane** (`pane-board` entrypoint, or `herdmates pane-board`):
  read-only team overview — overview line, per-agent rows with
  waiting-reason badges, native task list (`~/.claude/tasks/`), mailbox
  tail. Wakes event-driven on hook-spool growth, falls back to polling.
  - Keys: `j`/`k` select agent · `g` jump to its pane · `n` nudge
    (confirm with `y`/`Enter`, cancel with `Esc`) · `q` quit.
- **Sidebar tokens**: teammate state published via
  `pane report-metadata` — the herdr sidebar becomes a zero-rendering
  fleet board. See [Sidebar setup](#sidebar-setup).
- **Focus pane** (`focus` entrypoint): the human's single next action +
  decision queue from `~/.local/share/herdmates/focus.md` — one thing at
  a time, fed by the same signal engine as the board so the two surfaces
  cannot disagree.

### Signal engine, recorder, hooks

- **Signal engine** — single source of teammate-state truth. Four
  waiting-reason classes with strict precedence (permission-prompt >
  blocked > stalled > turn-complete), two-tier stalled detection on
  transcript mtime. Doctrine: **never display a wrong reason** — degrade
  to reason-less "waiting" instead.
- **Recorder** — `herdmates record --team <name>`: append-only JSONL log
  of the engine's classified deltas (baselines, transitions, task
  deltas, hook signals). Log schema = engine schema.
- **Hook companion** — `herdmates hook <event>` registered for Claude
  Code's three team hook events (`TeammateIdle` / `TaskCreated` /
  `TaskCompleted`) spools events per team; board and recorder consume
  the spool. Exit-2 gating capability exists but ships **default-off**
  and has no blocking predicate in v1.

## Sidebar setup

The plugin's event hooks already publish two tokens per team lead under
source id `herdmates-board` (`$task`, `$status`). Rendering is your own
`~/.config/herdr/config.toml`: merge
[`docs/sidebar-rows.toml`](docs/sidebar-rows.toml)'s
`[ui.sidebar.agents]` table in, then `herdr server reload-config`.

Hard-won facts (verified live against herdr 0.7.4):

- **Invalid token names fail silently** — `reload-config` reports
  `"partial"` and keeps the old layout. If an edit "does nothing," run
  `herdr config check` and re-verify every name (`state_text`, not
  `state_label`).
- **Keep values telegraphic** — ~20 visible columns at default sidebar
  width; herdmates enforces an 80-char wire cap but truncation is not a
  layout strategy.
- **Absent tokens omit the row** (safe to always configure), and
  **agent-less panes never appear** in the sidebar at all.

## Doctrine (why it behaves the way it does)

- **Honesty first**: never a wrong reason, never a predicted ETA, no
  silent coverage caps. Ambiguity degrades to an explicit error (e.g.
  team resolution lists candidates rather than guessing).
- **Native teams are the substrate**: spawn/messaging/lifecycle belong
  to Claude Code; herdmates only reads documented team files and drives
  the herdr CLI (`HERDR_BIN_PATH` is the entire plugin API).
- **Evidence hierarchy**: live behavior > source > docs (ADR-0010).
- **Writes are human-confirmed**: the only team-file write is the
  confirmed nudge, under an OS advisory lock with
  read-modify-atomic-rename.

## Documentation map

| Where | What |
|---|---|
| [`docs/spec.md`](docs/spec.md) | North-star specification (pillars, build order, cut line) |
| [`docs/adr/`](docs/adr/) | All architecture decisions with the why — start at [0013](docs/adr/0013-north-star-mission-control.md) (north star) and [0012](docs/adr/0012-pivot-to-herdmates.md) (the pivot) |
| [`CONTEXT.md`](CONTEXT.md) | Domain glossary (current vocabulary first, legacy below) |
| [`docs/research/`](docs/research/) | Verified upstream facts: tmux verb inventory, live E2E evidence, hook payload capture |
| [`docs/reviews/`](docs/reviews/) | Review program records, incl. the 2026-07-17 whole-codebase review |
| [`docs/learnings/`](docs/learnings/) | Per-issue wave learnings |
| [`docs/legacy/spec-v1.md`](docs/legacy/spec-v1.md) | Frozen v1.x orchestration spec (tombstone, ADR-0012) |
| [`herdr-plugin.toml`](herdr-plugin.toml) | The plugin manifest — commands, panes, event hooks |

## Development

```bash
cargo fmt && cargo clippy --all-targets -- -D warnings && cargo test
cargo install --path . --root "$HOME/.local"   # user-seat binaries
herdr plugin link .                            # refresh manifest cache
```

- Pure logic (file-contract parsing, token formatting, verb mapping)
  stays separate from process-spawning code — testable without a live
  herdr.
- Herdr caches the manifest at link time — relink after any
  `herdr-plugin.toml` change.
- Pushes to `main` are releases: gated, version-bumped, tagged.

## Legacy: v1.x team orchestration (frozen)

The original plugin spawned heterogeneous coding-agent teams (Claude +
Codex) under a coordinating "god" session with push-based status
reporting. Frozen at v1.1.0 (ADR-0012); the code remains in-tree, the
spec at [`docs/legacy/spec-v1.md`](docs/legacy/spec-v1.md), and it
receives no further investment.
