Agent Skills for OpenAI Codex CLI¶
Use 192 production-ready agent skills with OpenAI Codex CLI. Every skill in this collection works natively with Codex via the .codex/skills/ directory format.
Quick Install¶
# Clone the repository
git clone https://github.com/alirezarezvani/claude-skills.git
cd claude-skills
# Option 1: Install all skills for Codex
./scripts/codex-install.sh
# Option 2: Convert specific skills
./scripts/convert.sh --skill frontend-design --tool codex
./scripts/convert.sh --skill autoresearch-agent --tool codex
# Option 3: Convert all skills at once
./scripts/convert.sh --all --tool codex
How It Works¶
Codex reads agent skills from .codex/skills/<skill-name>/SKILL.md in your project or home directory. The convert.sh script transforms Claude Code's SKILL.md format into Codex-compatible instructions, preserving all workflows, slash commands, and references.

Codex-Specific Tips¶
AGENTS.md Fallback¶
If your Codex setup uses AGENTS.md instead of the skills directory, you can use the generated agents file:
Using with --full-auto¶
Skills work seamlessly with Codex's auto-approval mode:
# Run a skill in full-auto mode
codex exec --full-auto "Use the frontend-design skill to build a dashboard component"
# Run autoresearch overnight
codex exec --full-auto "Use autoresearch-agent to optimize src/api/search.py for response time"
Project-Level vs Global¶
# Project-level (only this repo)
cp -r claude-skills/.codex/skills/ ./.codex/skills/
# Global (available everywhere)
cp -r claude-skills/.codex/skills/ ~/.codex/skills/
