Codex CLI Skill for Read-Only Reviews from Claude Code
Hand a specific repository check from an agent such as Claude Code to the local Codex CLI. The skill checks whether Codex is available, passes a working directory and success condition, and helps you compare the result with the actual files.
中文Install in Claude Code 等本地代理，调用 Codex CLI
An installed and authenticated Codex CLI, plus a host agent with local shell access. The Bash example needs a readable demo directory. Manual installation has no Node.js dependency. The upstream npx installer requires Node.js and npm.
- From the pinned GitHub revision, copy `skills/codex-cli/` into the Claude Code workspace as `.claude/skills/codex-cli/`. Keep `SKILL.md` immediately inside that folder.
- Run `codex --version` and `codex exec --help` in the same shell to check that `-C` and `-s read-only` are available.
- Open the demo workspace in the host agent and ask it to use the codex-cli skill. The direct command below checks the same workflow.
Example task
Make a local demo directory containing a `sample.txt` file with the single line `Report: one row`. Run this Bash command from the directory.
codex exec -C "$PWD" -s read-only "Read only sample.txt. Report the line count and exact first line. Do not edit files."What to check
The response reports one line and quotes `Report: one row`. Compare it with the test file and confirm the contents stayed the same. Keep the actual error if the CLI is unavailable or the call fails.

Frequently asked question
Does this skill install the Codex CLI for me?
Install and authenticate Codex separately. The skill guides a host agent through invoking the installed CLI and checking what it returns.
