Agent Team Pipeline

Overview

Coordinate OpenClaw as the brain dispatching multiple Codex instances in parallel: one for coding, one for testing, one for code review. Each agent works in an isolated git worktree to avoid conflicts.

When to Use

• Need to implement a feature with separate code/test/review phases
• Want parallel execution of independent tasks
• Building a mini development team workflow

Not for:

• Single simple tasks (use single agent)
• Exploratory discussions requiring multi-round dialogue

Core Pattern

User → OpenClaw (brain) → Codex Coder → Codex Tester → Codex Reviewer
                        → Codex Tester (parallel)
                        → Codex Reviewer (parallel)

Setup

1. Create Isolated Worktrees

cd /Users/liuchang/.openclaw/workspace
git worktree add -b coder /Users/liuchang/agent-coder HEAD
git worktree add -b tester /Users/liuchang/agent-tester HEAD
git worktree add -b reviewer /Users/liuchang/agent-reviewer HEAD

2. Task Distribution Script

#!/bin/bash
CODER_DIR="/Users/liuchang/agent-coder"
TESTER_DIR="/Users/liuchang/agent-tester"
REVIEWER_DIR="/Users/liuchang/agent-reviewer"

case "$1" in
    coder)
        cd "$CODER_DIR" && codex exec "$2"
        ;;
    tester)
        cd "$TESTER_DIR" && codex exec "$2"
        ;;
    reviewer)
        cd "$REVIEWER_DIR" && codex exec "$2"
        ;;
esac

3. Workflow

1. Coder receives task, writes code to agent-coder/
2. Tester receives code, writes tests to agent-tester/
3. Reviewer reviews code, provides feedback
4. Loop: Coder addresses feedback → Reviewer confirms

Quick Reference

Example

# Coder: Implement feature
codex exec "创建登录功能，使用 JWT"

# Tester: Write tests  
codex exec "为 ../agent-coder/login.py 写测试"

# Reviewer: Review code
codex exec "审查 ../agent-coder/login.py"

Common Mistakes

• No worktree isolation → Use git worktree to prevent file conflicts
• Sequential when parallel → Coder+Tester+Reviewer can run in parallel
• Skipping review loop → Always verify fixes with reviewer before accepting

Real-World Impact

Successfully implemented hello.py example:

• Coder created initial code
• Tester wrote pytest file
• Reviewer suggested main() + __main__ protection
• Coder applied fixes
• Reviewer confirmed compliance
