Enable Claude Code to invoke the Codex CLI (codex exec and session resumes) for automated code analysis, refactoring, and editing workflows.
codex CLI installed and available on PATH.codex --version; resolve any errors before using the skill.This repository is structured as a Claude Code Plugin with a marketplace. You can install it as a plugin (recommended) or extract it as a standalone skill.
Install via Claude Code's plugin system for automatic updates:
/plugin marketplace add skills-directory/skill-codex
/plugin install skill-codex@skill-codex
Extract the skill folder manually:
git clone --depth 1 git@github.com:skills-directory/skill-codex.git /tmp/skills-temp && \
mkdir -p ~/.claude/skills && \
cp -r /tmp/skills-temp/plugins/skill-codex/skills/codex ~/.claude/skills/codex && \
rm -rf /tmp/skills-temp
By default, this skill suppresses thinking tokens (stderr output) using 2>/dev/null to avoid bloating Claude Code's context window. If you want to see the thinking tokens for debugging or insight into Codex's reasoning process, explicitly ask Claude to show them.
User prompt:
Use codex to analyze this repository and suggest improvements for my claude code skill.
Claude Code response: Claude will activate the Codex skill and:
gpt-5.5, gpt-5.4, gpt-5.4-mini, gpt-5.3-codex-spark, or gpt-5.3-codex) unless already specified in your prompt.low, medium, or high) unless already specified in your prompt.read-only for analysis)codex exec -m gpt-5.3-codex-spark \
--config model_reasoning_effort="high" \
--sandbox read-only \
--full-auto \
--skip-git-repo-check \
"Analyze this Claude Code skill repository comprehensively..." 2>/dev/null
Result: Claude will summarize the Codex analysis output, highlighting key suggestions and asking if you'd like to continue with follow-up actions.
