Codex Delegate

繁體中文

codex-delegate is a Claude-oriented skill for using Codex CLI as an execution specialist for implementation-heavy coding work while keeping planning, review, and acceptance in Claude.

📚 Part of the agentic AI learning roadmap — a 7-stage curated path for building agentic AI, multilingual (zh-TW · zh-CN · English). This skill is referenced in §13 (Multi-LLM Delegation).

Positioning

This skill is for tasks that are expensive in tokens but cheap in judgment:

• multi-file implementation
• mechanical refactors
• boilerplate generation
• test scaffolding
• large batch edits

It is not meant for architecture, root-cause debugging, security review, or ambiguous product decisions.

What Changed In This Version

• clearer routing boundary between Claude, Codex, and Gemini
• explicit supervisor acceptance gate
• machine-readable wrapper output via <log>.result.json
• regression tests for bash and PowerShell wrappers

Core Pattern

1. Claude writes a task file describing scope and constraints.
2. Claude launches Codex synchronously through the wrapper.
3. The wrapper emits sentinel files plus result.json.
4. Claude reviews the diff and runs verification before accepting the result.

Wrapper success is not final acceptance. Claude still owns the judgment.

Relation to openai/codex-plugin-cc

OpenAI ships an official Codex integration for Claude Code, openai/codex-plugin-cc. It is a capable, broker-based plugin — and a different design point from this skill. The two are complementary; the table below is meant to help you pick, not to rank them.

Aspect	codex-delegate (this repo)	openai/codex-plugin-cc
Form	A single Claude Code skill	A multi-command plugin suite
Execution model	Thin synchronous wrapper: run → write result.json → exit	Persistent broker process with background jobs
Job tracking	None by design — one run, one result	/codex:status, /codex:result, /codex:cancel
Invocation	Claude invokes the skill; the wrapper script runs Codex	Slash commands (/codex:review, /codex:rescue, …) plus a proactive subagent
Review gate	Claude's own acceptance gate (skills/codex-delegate/references/review-checklist.md)	Optional Stop-hook review gate
Platform	bash + PowerShell wrappers, Windows-tested, no Node runtime	Node.js 18.18+ runtime
Delegate routing	Three-way Claude / Codex / Gemini routing table	Codex-focused
Maintainer · License	Wenyu Chiou · MIT	OpenAI · Apache-2.0

In short: reach for codex-plugin-cc when you want background async jobs, a slash-command UX, and an OpenAI-maintained integration. Reach for codex-delegate when you want a thin, synchronous, supervisor-gated skill that keeps acceptance in Claude, behaves the same on Windows and Linux, and routes across Claude / Codex / Gemini.

codex-delegate also borrows from the official plugin: the prompt-engineering reference (skills/codex-delegate/references/codex-prompt-blocks.md) is adapted from its gpt-5-4-prompting skill (Apache-2.0).

Current wrapper tests cover:

• success-path result.json generation
• PowerShell wrapper contract behavior

Installation

1. Install the skill via the ai-research-skills Claude Code marketplace:

claude plugin marketplace add WenyuChiou/ai-research-skills
claude plugin install codex-delegate@ai-research-skills

Default scope is user (this OS account, all projects). Add --scope project to install only for the current project.

2. Make sure Codex CLI is on $PATH:

npm install -g @openai/codex
codex --version
