# Task Orchestrator

Autonomous orchestration of multi-agent builds using tmux + Codex with self-healing monitoring.

**Load the senior-engineering skill alongside this one for engineering principles.**

## Core Concepts

### 1. Task Manifest
A JSON file defining all tasks, their dependencies, files touched, and status.

```json
{
  "project": "project-name",
  "repo": "owner/repo",
  "workdir": "/path/to/worktrees",
  "created": "2026-01-17T00:00:00Z",
  "model": "gpt-5.2-codex",
  "modelTier": "high",
  "phases": [
    {
      "name": "Phase 1: Critical",
      "tasks": [
        {
          "id": "t1",
          "issue": 1,
          "title": "Fix X",
          "files": ["src/foo.js"],
          "dependsOn": [],
          "status": "pending",
          "worktree": null,
          "tmuxSession": null,
          "startedAt": null,
          "lastProgress": null,
          "completedAt": null,
          "prNumber": null
        }
      ]
    }
  ]
}
```

### 2. Dependency Rules
- **Same file = sequential** — Tasks touching the same file must run in order or merge
- **Different files = parallel** — Independent tasks can run simultaneously
- **Explicit depends = wait** — `dependsOn` array enforces ordering
- **Phase gates** — Next phase waits for current phase completion

### 3. Execution Model
- Each task gets its own **git worktree** (isolated branch)
- Each task runs in its own **tmux session**
- Use **Codex with --yolo** for autonomous execution
- Model: **GPT-5.2-codex high** (configurable)

## Setup Commands

### Initialize Orchestration

```bash
# 1. Create working directory
WORKDIR="${TMPDIR:-/tmp}/orchestrator-$(date +%s)"
mkdir -p "$WORKDIR"

# 2. Clone repo for worktrees
git clone https://github.com/OWNER/REPO.git "$WORKDIR/repo"
cd "$WORKDIR/repo"

# 3. Create tmux socket
SOCKET="$WORKDIR/orchestrator.sock"

# 4. Initialize manifest
cat > "$WORKDIR/manifest.json" << 'EOF'
{
  "project": "PROJECT_NAME",
  "repo": "OWNER/REPO",
  "workdir": "WORKDIR_PAT...
