codex-orchestrator（Codex 编排器）

Codex Orchestrator

Spawn specialized Codex CLI subagents for focused development tasks. Each profile injects a custom AGENTS.md persona that shapes the agent's behavior, focus areas, and output format.

Architecture

Claude Code (orchestrator)
    ↓ invokes skill
codex-orchestrator scripts
    ↓ spawns via Bash
Codex CLI with AGENTS.md
    ↓ executes
Specialized subagent task

Prerequisites

Verify Codex CLI is installed and configured:

~/.claude/skills/codex-orchestrator/scripts/codex-status.sh

Required:

• Codex CLI: npm install -g @openai/codex
• API Key: export OPENAI_API_KEY=sk-...

Auto-Update

The skill automatically checks for Codex CLI updates on each invocation and updates if needed. This prevents issues caused by outdated CLI versions.

To manually check/update:

# Check version only
~/.claude/skills/codex-orchestrator/scripts/codex-version-check.sh

# Check and auto-update if needed
~/.claude/skills/codex-orchestrator/scripts/codex-version-check.sh --auto-update

Available Profiles

Quick Execution

Execute a one-shot task with a specific profile:

~/.claude/skills/codex-orchestrator/scripts/codex-exec.sh <profile> "<prompt>"

Examples:

Session Management

For more control, use the Python session manager:

# List available profiles
python3 ~/.claude/skills/codex-orchestrator/scripts/codex-session.py list

# Start non-interactive session
python3 ~/.claude/skills/codex-orchestrator/scripts/codex-session.py start debugger "Trace the null pointer in UserService"

# Start interactive session
python3 ~/.claude/skills/codex-orchestrator/scripts/codex-session.py interactive architect

# Show profile details
python3 ~/.claude/skills/codex-orchestrator/scripts/codex-session.py info security

Profile Selection Guide

Review Tasks

Chaining Patterns

Review → Debug → Fix

# 1. Identify issues
~/.claude/skills/codex-orchestrator/scripts/codex-exec.sh reviewer "Review src/api/ for bugs"

# 2. Investigate specific bug
~/.claude/skills/codex-orchestrator/scripts/codex-exec.sh debugger "Debug the race condition found in cache.ts"

Planner → Architect → Builder

# 1. Create comprehensive ExecPlan
~/.claude/skills/codex-orchestrator/scripts/codex-exec.sh planner "Create ExecPlan for new authentication system"

# 2. Validate architecture
~/.claude/skills/codex-orchestrator/scripts/codex-exec.sh architect "Review the auth system ExecPlan for design issues"

# 3. Build (plan guides implementation)
~/.claude/skills/codex-orchestrator/scripts/codex-exec.sh builder "Implement milestone 1 from the auth ExecPlan" --full-auto

Architect → Builder → Reviewer

# 1. Design approach
~/.claude/skills/codex-orchestrator/scripts/codex-exec.sh architect "Design a caching layer for the API"

# 2. Build the feature
~/.claude/skills/codex-orchestrator/scripts/codex-exec.sh builder "Implement the caching layer from architect's design"

# 3. Review the implementation
~/.claude/skills/codex-orchestrator/scripts/codex-exec.sh reviewer "Review the new caching implementation"

Architect → Review → Refactor

# 1. Design approach
~/.claude/skills/codex-orchestrator/scripts/codex-exec.sh architect "Design repository layer extraction"

# 2. Validate design
~/.claude/skills/codex-orchestrator/scripts/codex-exec.sh reviewer "Review the proposed repository pattern"

# 3. Implement
~/.claude/skills/codex-orchestrator/scripts/codex-exec.sh refactor "Extract repository pattern from services"

Syseng → Architect → Planner

# 1. Assess infrastructure needs
~/.claude/skills/codex-orchestrator/scripts/codex-exec.sh syseng "Evaluate current deployment for scaling to 10x traffic"

# 2. Design architecture changes
~/.claude/skills/codex-orchestrator/scripts/codex-exec.sh architect "Design infrastructure to support 10x scale"

# 3. Create implementation plan
~/.claude/skills/codex-orchestrator/scripts/codex-exec.sh planner "Create ExecPlan for infrastructure scaling"

Security → Syseng

# 1. Security audit
~/.claude/skills/codex-orchestrator/scripts/codex-exec.sh security "Audit the Kubernetes cluster configuration"

# 2. Infrastructure hardening
~/.claude/skills/codex-orchestrator/scripts/codex-exec.sh syseng "Implement security recommendations from audit"

Researcher → Architect → Builder

# 1. Understand the problem space
~/.claude/skills/codex-orchestrator/scripts/codex-exec.sh researcher "How does the current caching work? What are its limitations?"

# 2. Design the solution
~/.claude/skills/codex-orchestrator/scripts/codex-exec.sh architect "Design a new caching layer addressing the limitations"

# 3. Implement
~/.claude/skills/codex-orchestrator/scripts/codex-exec.sh builder "Implement the caching layer from architect's design"

Script Options

codex-exec.sh Options

Model & Reasoning Defaults

Each profile has a default model and reasoning effort. User flags override these.

Reasoning effort levels: none < minimal < low < medium < high < xhigh

# Uses profile defaults (builder → gpt-5.4 + high)
~/.claude/skills/codex-orchestrator/scripts/codex-exec.sh builder "Implement auth module"

# Uses profile defaults (planner → gpt-5.4-pro + high)
~/.claude/skills/codex-orchestrator/scripts/codex-exec.sh planner "Create ExecPlan for caching"

# Override model for quick tasks
~/.claude/skills/codex-orchestrator/scripts/codex-exec.sh reviewer "Style check" --model gpt-5-mini

# Override reasoning only
~/.claude/skills/codex-orchestrator/scripts/codex-exec.sh builder "Quick lint fix" --reasoning medium

# Override both
~/.claude/skills/codex-orchestrator/scripts/codex-exec.sh planner "Design distributed cache" --model gpt-5.4 --reasoning high

Testing

Run the test suite to verify installation:

~/.claude/skills/codex-orchestrator/scripts/test-codex.sh         # Full tests
~/.claude/skills/codex-orchestrator/scripts/test-codex.sh --quick # Skip API test

Troubleshooting

"Codex CLI not found"

npm install -g @openai/codex

"Authentication error"

export OPENAI_API_KEY=sk-...
# or
codex login

"Model not supported with ChatGPT account"

Older model names (codex-mini, o3, o4-mini) have been deprecated. Current models: gpt-5.4, gpt-5.4-pro, gpt-5-mini, gpt-5-nano. Previous generation (gpt-5.3-codex, gpt-5.3-codex-spark, gpt-5.2) still works but is superseded. Set an API key instead of using codex login:

export OPENAI_API_KEY=sk-...

"Profile not found"

Available profiles: reviewer, debugger, architect, security, refactor, docs, planner, syseng, builder, researcher

Check profile exists:

ls ~/.claude/skills/codex-orchestrator/agents/

Poor Results

• Narrow the task scope
• Provide more context in the prompt
• Try a different profile
• Use --model gpt-5.4-pro for complex tasks
