Codex Swarm — Multi-Agent Orchestration

Parallel Codex agents: plan → endorse → spawn → monitor → review → integrate → ship.

Quick Start

# 1. Write task prompts
cat > /tmp/prompt-task1.md << 'EOF'
Implement feature X...
EOF

# 2. Create tasks JSON
cat > /tmp/tasks.json << 'EOF'
[
  {"id": "feat-x", "description": "/tmp/prompt-task1.md", "role": "builder"},
  {"id": "feat-y", "description": "/tmp/prompt-task2.md", "role": "builder"}
]
EOF

# 3. Spawn batch
bash scripts/spawn-batch.sh "/path/to/project" "batch-1" "Description" /tmp/tasks.json

Roles & Models

Role Model Reasoning Use
architect o3 high Design, planning, complex decisions
builder codex-mini medium Feature implementation (parallel)
reviewer o3 medium Auto-review via codex exec review
integrator o3 high Cross-branch merge + conflict resolution

Key Codex Features Used

  • codex exec --full-auto — non-interactive sandboxed execution
  • codex exec review — native code review (replaces custom reviewer)
  • -c model=o3 — deep reasoning model for complex tasks
  • -c model_reasoning_effort=high — maximum reasoning depth

Scripts

Script Purpose
spawn-batch.sh Spawn N parallel agents + integration watcher
spawn-agent.sh Spawn single agent (manual worktree + tmux + codex exec)
endorse-task.sh Endorse task before spawn
check-agents.sh Show running agent status
cleanup.sh Remove worktrees, branches, sessions
notify.sh Webhook/Telegram notification
notify-on-complete.sh Auto-watcher with native codex exec review
integration-watcher.sh Auto-merge when batch completes

Setup

  1. Copy scripts/ and config/ to your workspace
  2. Configure config/swarm.conf (copy from .example)
  3. Required: bash 4+, tmux, git, gh, jq, codex (Codex CLI)
