Can I install skills from my own private GitHub repository?

Yes, the installer supports private repositories by utilizing your local git credentials or an optional GITHUB_TOKEN environment variable.

Do I need to restart Claude after installing a new skill?

Yes, you must restart the Codex or Claude Code environment to pick up and initialize any newly installed skills.

Where are the skills stored on my local machine?

Skills are installed into the $CODEX_HOME/skills directory, which typically defaults to the ~/.codex/skills folder on your system.

What happens if I try to install a skill that is already present?

The installer will abort the operation for that specific skill to prevent overwriting your existing configuration, unless you specifically choose to overwrite it.

How do I see which skills are available to install?

You can use the installer to fetch a curated list of skills from the official repository, which will display available tools along with annotations for those already installed.
