## Agent Orchestration

Run parallel AI agents in isolated git worktrees — each with its own branch, tmux window, and full repo copy. Controlled entirely via MCP tools so LLMs can orchestrate other agents. The TUI shows a colored **`wt:branch(status)`** badge on worktree-backed windows — yellow while running, green when done.

### MCP tools

```
launch_agent(session, prompt, branch?, base_branch?, agent_command?)  → create worktree + window + run agent
merge_worktree(branch, commit_message?, test_command?) → test + commit + merge to main + cleanup
discard_worktree(branch)                               → force-remove worktree + delete branch
list_worktrees()                                       → list worktrees with status (running/done/idle)
diff_worktree(branch)                                  → git diff main...branch
read_agent_log(branch)                                 → read saved agent output after merge/discard
```

### Example: agents spawning agents

```
Agent: launch_agent("dev", "fix the login bug")
  → creates worktree + branch, opens window, runs claude -p

Agent: launch_agent("dev", "add dark mode", branch="feat-dark")
  → same, with explicit branch name

Agent: list_worktrees()
  → [{"branch": "fix-the-login-bug", "status": "running", ...}, ...]

Agent: diff_worktree("fix-the-login-bug")
  → shows all changes on the branch vs main

Agent: merge_worktree("fix-the-login-bug", test_command="pytest")
  → runs tests first, then git add + commit + merge --no-ff + cleanup
  → agent output saved to .worktrees/fix-the-login-bug.log

Agent: read_agent_log("fix-the-login-bug")
  → reads the saved terminal output

Agent: discard_worktree("feat-dark")
  → agent output saved, then force-remove worktree + delete branch
```

### Stacked agents

Build on another agent's work using `base_branch`:

```
Agent: launch_agent("dev", "add auth", branch="feat-auth")
Agent: launch_agent("dev", "add auth tests", branch="feat-auth-tests", base_branch="feat-auth")
```

### How it works

| Step | What happens |
|------|-------------|
| **Launch** | `git worktree add -b <branch> .worktrees/<branch>` → `tmux new-window` → `claude -p "prompt"` |
| **Merge** | capture output → optional test gate → `git add -A` → `git commit` → `git merge --no-ff` → cleanup |
| **Discard** | capture output → `git worktree remove --force` → `git branch -D` |

Worktree windows survive tmuxx restarts — auto-discovered by matching pane paths against `git worktree list`. Merge conflicts are caught and reported with the worktree preserved for manual resolution.

## MCP Server

tmuxx includes an MCP (Model Context Protocol) server that lets LLMs observe and control tmux sessions via tool calls.

### Setup

```bash
pip install "tmuxx[mcp]"
```

This installs the `tmuxx-mcp` command, which runs a stdio-based MCP server.

### Add to Claude Code

```bash
claude mcp add tmuxx -- tmuxx-mcp
```

### Add to Claude Desktop

Add to your `claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "tmuxx": {
      "command": "tmuxx-mcp"
    }
  }
}
```

### Scenarios

**1. Dev environment setup**

> "Set up a dev environment for this project"

```
Agent: create_session("backend")
Agent: send_command(%0, "cd ~/project && cargo run")
Agent: create_window("backend", "logs")
Agent: send_command(%1, "tail -f /var/log/app.log")
Agent: create_session("frontend")
Agent: send_command(%2, "cd ~/project/web && npm run dev")
Agent: split_pane(%2, horizontal=True)
Agent: send_command(%3, "npm run test -- --watch")
```

You open tmuxx, see everything running. Agent sees the same.

**2. Debug a failing service**

> "The API server crashed, check what happened"

```
Agent: list_sessions()
Agent: capture_pane(%0)           → reads the error traceback
Agent: screenshot_window(@0)      → sees the full terminal layout
Agent: send_command(%0, "git log --oneline -5")
Agent: run_and_capture(%0, "curl localhost:8080/health", wait_seconds=2)
Agent: send_command(%0, "cargo run")
Agent: capture_pane(%0)           → confirms it's running again
```

You watch the agent diagnose and restart in real time.

**3. Parallel agents on separate tasks**

> "Fix the auth bug and add rate limiting at the same time"

```
Agent: launch_agent("dev", "fix the auth token refresh bug")
  → worktree: .worktrees/fix-the-auth-token-refresh-bug
  → window opens, claude starts working

Agent: launch_agent("dev", "add rate limiting to the API")
  → worktree: .worktrees/add-rate-limiting-to-the-api
  → second window opens, second claude starts working

Agent: list_worktrees()           → check progress
Agent: capture_pane(%5)           → read what the auth agent is doing

# Auth agent finishes first
Agent: merge_worktree("fix-the-auth-token-refresh-bug")
  → merged to main, worktree cleaned up

# Rate limiting needs more work, discard it
Agent: discard_worktree("add-rate-limiting-to-the-api")
```

**4. Test matrix across environments**

> "Run the test suite across three environments"

```
Agent: create_session("test-matrix")
Agent: send_command(%0, "docker run -e PG=14 ./test.sh")
Agent: split_pane(%0)
Agent: send_command(%1, "docker run -e PG=15 ./test.sh")
Agent: split_pane(%0, horizontal=True)
Agent: send_command(%2, "docker run -e PG=16 ./test.sh")
Agent: screenshot_window(@0)      → sees all three running side by side
# ...waits...
Agent: capture_window(@0)         → reads all results at once
```

**5. Pair programming**

You're working in tmux. Agent watches over your shoulder.

```
Agent: list_sessions()            → finds your active session
Agent: capture_pane(%0)           → reads what you're looking at
Agent: split_pane(%0)
Agent: send_command(%1, "rg 'TODO' --type rust")
Agent: capture_pane(%1)           → shares findings with you
```

You see the new pane appear. Both sides transparent.
