Quickstart: Add Skills to Codex

Install with the Skill Installer (recommended)

git clone 
cd awesome-codex-skills/awesome-codex-skills
# Install one or more skills into $CODEX_HOME/skills (defaults to ~/.codex/skills)
python skill-installer/scripts/install-skill-from-github.py --repo ComposioHQ/awesome-codex-skills --path meeting-notes-and-actions

The installer fetches the skill and places it in $CODEX_HOME/skills/. Restart Codex to pick up new skills.

Manual install

1. Copy the desired skill folder (e.g., ./spreadsheet-formula-helper) into $CODEX_HOME/skills/ (defaults to ~/.codex/skills/).
2. Restart Codex so it loads the new metadata.
3. In your next session, describe the task or mention the skill name; Codex will trigger matching skills based on their description frontmatter.

What Are Codex Skills?

Codex skills are modular instruction bundles that tell Codex how to execute a task the way you want it done. Each skill lives in its own folder with a SKILL.md that includes metadata (name + description) and step-by-step guidance. Codex reads the metadata to decide when to trigger a skill and loads the body only after it fires, keeping context lean.
