当用户明确要求直接操作 Codex CLI 作为后台代理（自选 sandbox、codex review、apply、resume 等原生命令，或用 git worktree 并行布置多个 worker）做代码分析、编辑、审查时使用。普通的“让 Codex 或 GPT-6 写代码、调研、review”派单走 agent-fleet（fleet code）；图片生成与网站视觉素材走 imagegen。.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Codex 后台代理 用 Codex CLI 承接用户指定的代码分析、编辑、审查或并行代理任务。图片生成的当前流程见 [`imagegen/SKILL.md`](../imagegen/SKILL.md)；旧版操作与实验记录保存在 [`references/image-experiments.md`](references/image-experiments.md)。 **路由前提**：按全局 `CLAUDE.md` §2，编码、修 bug、调研与 review 默认用 `fleet code`（`gpt-6.1-sol`，见 [`agent-fleet`](../agent-fleet/skill/SKILL.md)），不手写 `codex exec`。本 Skill 只在用户明确要求直接操作 Codex CLI（自选 sandbox、`codex review`/`apply`/`resume` 等原生子命令、并行 worker 的 worktree 布置）时使用；简单派单不要先读本文件。 ## Core Principle **Never block the main conversation on a `codex exec` call.** Always launch via `Bash` with `run_in_background: true`. The only exception is a trivial `codex --version` health check. ## Launching a Codex Sub-Agent 1. **Pick reasoning effort + sandbox** from context — do not interrupt the user with `AskUserQuestion` unless they explicitly ask to be prompted. Model is `gpt-6.1-sol` (the default in `~/.codex/config.toml`; pass `-m` only when the user names another model in the current request). Defaults: - Reasoning effort: `medium`; `low` for single-file edits with clear boundaries. **Never escalate to `high`/`xhigh` on your own** (global §2); only when the user asks for it explicitly …

How to install
mdr add yan-labs/yan-skills/codex@sha256:f88a87d058e6c1a9The line at the top of this page pins the label git:20260930.3f793f3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
