FAQPage Schema
How do I install Codex skills from a GitHub repository?

Install Codex skills from GitHub by providing a repository path or URL. The installer uses direct download or git sparse checkout to place validated skills into CODEX_HOME/skills, including support for private repos with token authentication.

Can I install skills from private GitHub repositories?

Yes, installing skills from private GitHub repositories is supported with token authentication. Provide your access token during installation to authenticate and pull skill directories directly into your local CODEX_HOME/skills environment.

What is the safest way to install Codex skills locally without overwriting existing ones?

Safe skill installation validates that each directory contains SKILL.md and avoids overwriting existing skills. This ensures your current local skill inventory in CODEX_HOME/skills remains intact when adding new entries from curated lists.

How do I list available Codex skills before installing them?

List available skills by running the installer against curated sources or GitHub paths. This displays installable skills before selection, allowing you to review and choose specific skill directories to install locally or from URLs.

Does the Codex skill installer support custom destination naming?

Yes, the installer supports optional destination naming when installing skills. You can specify custom names for skill directories fetched from local paths, URLs, or GitHub repositories during the installation process.

Why does installing a skill require a SKILL.md file?

Installing a skill requires SKILL.md to enforce safe installation and validate structure. The installer checks each skill directory for this file before placing it into CODEX_HOME/skills, preventing incomplete or invalid skill deployments.
