How do I install Codex skills from a GitHub repository?

To install Codex skills from a GitHub repository, provide the repository path to the installer. It validates the presence of SKILL.md, downloads the skill, and copies it directly into CODEX_HOME/skills.

What are curated lists for installing skills in Codex?

Curated lists for installing skills in Codex are predefined sets of available open-source skills. The installer reads these lists to let you discover, preview, and install validated skills by name.

Can I list available Codex skills before installing them?

Yes, you can list available Codex skills before installing them. The installer displays all installable skills from curated sources or GitHub paths and indicates whether each skill is already installed.

Does the Codex skill installer validate SKILL.md before copying?

Yes, the Codex skill installer validates SKILL.md before copying. It ensures the file exists at the root of the source repository and provides clear error messages if the validation fails.

Why does my GitHub skill installation fail in Codex?

GitHub skill installation in Codex fails when the source repository lacks a SKILL.md file at its root or when the GitHub path is outside allowed sources. The installer outputs clear error messages identifying the exact validation issue.

Do I need to manually checkout skills into CODEX_HOME/skills?
