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

To install Codex skills from a GitHub repository, use the skill-installer to fetch content from curated sources or external repo paths. It automatically validates for a SKILL.md file and safely installs the skill content directly into your CODEX_HOME/skills directory.

Can I install Codex skills from private GitHub repositories?

Yes, you can install Codex skills from private GitHub repositories. The installation process supports both download-based and sparse Git methods to securely fetch necessary skill content while automatically validating the required SKILL.md file.

What is the best way to list and identify already installed Codex skills?

Listing curated Codex skills from a central repository allows you to identify which skills are already installed in your environment. This automated process checks your CODEX_HOME/skills directory against available curated sources to show current installation status.

Does installing a skill from external repos require a SKILL.md file?

What is the difference between download and sparse Git methods for fetching skills?

Fetching skills via download or sparse Git methods determines how content is retrieved from GitHub repositories. Both deterministic fetch methods extract only the necessary skill content, validate the SKILL.md file, and install safely into CODEX_HOME/skills without pulling the entire repository.
