Overview
Use OpenAI Codex CLI as an external worker inside a Claude Code workflow.
Best for:
- implementation-oriented feedback
- code-aware review
- execution-heavy coding tasks
Install
This sub-skill can be installed independently:
skill install https://github.com/Harzva/usecli-codex
Or manually:
git clone https://github.com/Harzva/usecli-codex.git
mkdir -p ~/.claude/skills
ln -s $(pwd) ~/.claude/skills/usecli-codex
Command
bash ~/.claude/skills/usecli-codex/scripts/usecli-codex.sh --prompt "<prompt>"
Or with a prompt file:
bash ~/.claude/skills/usecli-codex/scripts/usecli-codex.sh --prompt-file <path>
Verification
Run the local smoke test:
bash ~/.claude/skills/usecli-codex/tests/test_wrapper.sh
