claude-codex-subagent: Instructions file for Claude Code

CLAUDE.md

claude-codex-subagent CLAUDE.md is an instructions file for Claude Code from dwgx/claude-codex-subagent. It costs 702 tokens per session, scanned A, original, MIT.

Repository-specific instructions for a project that uses Codex as a worker subagent for Claude Code. They explain what work to delegate, how to run Codex, how to choose sandbox and web-search settings, and how to write prompts and personas.

In plain words
What is it for?
Use them when maintaining the Claude-to-Codex subagent system, dispatching repository analysis or tests, writing prompts, or configuring Codex execution. The default maintainer response language is Chinese unless English is requested.
Why use it?
They give maintainers consistent rules for splitting work between Claude and Codex while keeping approvals, repository access, and current web research deliberate. They also document defaults for the versions and tools used by the project.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions subagents; mentions Claude Code; runs codex exec.

This is dwgx/claude-codex-subagent's own configuration. It tells Claude Code how to work on claude-codex-subagent itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything claude-codex-subagent configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

claude-codex-subagent CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Claude Maintainer Guide

Default answer language for this maintainer is Chinese unless the user asks for English. Keep responses direct and evidence-backed.

What This Repo Teaches

This repo teaches Claude Code to use local Codex as a worker subagent. Claude keeps orchestration, judgment, and user conversation state. Codex handles context-heavy or tool-heavy work: current web facts, large reads, bulk repo analysis, long file writes, audits, test runs, and fresh-context debugging.

Dispatch Defaults

For Codex CLI 0.141.0+:

codex exec --skip-git-repo-check --sandbox workspace-write -C <repo> -

Use stdin for generated or multiline prompts. Do not teach new examples with --full-auto; it is deprecated. If a persona still says sandbox: full-auto, the wrapper treats it as a legacy alias for --sandbox workspace-write.

Escalate deliberately:

  • --sandbox workspace-write: normal local repo reads, edits, tests, lint, build.
  • --search: helper-script shorthand for current public web facts. Direct codex exec uses --config web_search="live"; top-level interactive codex supports --search.
  • --dangerously-bypass-approvals-and-sandbox: shell network, cross-workspace access, global installs, or Windows sandbox ACL fallback after reporting the exact error.
  • --ephemeral: throwaway checks that should not persist a session.
  • --json, -o, --output-schema: automation and machine-readable outputs.

How To Prompt Codex

Every dispatch prompt should include:

  • goal and done condition,
  • scope and working directory,
  • what not to touch,
  • exact return format,
  • verification expectations,
  • whether file edits are allowed.

Prefer short final returns. The point of this skill is to avoid reinflating the main Claude context with Codex's full internal work.

Use Personas

  • reviewer: severity-ranked code review.
  • debugger: fresh root-cause analysis.
  • auditor: security audit.
  • researcher: current web/docs research.
  • refactorer: cleanup/dead-code/stale TODO survey.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
