Awesome Codex Skills

A curated list of practical Codex skills for automating workflows across the Codex CLI and API.

Give your skills real-world actions

Skills tell your agent how to work. An MCP Gateway gives it secure access to the tools it needs.

Composio MCP Gateway provides a single MCP endpoint for 1,000+ integrations with built-in authentication, team-based access controls, audit logs, and production-ready reliability.

Quickstart: Add Skills to Codex

Install with the Skill Installer (recommended)

git clone https://github.com/ComposioHQ/awesome-codex-skills.git
cd 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/<skill-name>. 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.

Using Skills in Codex

• Skills live in $CODEX_HOME/skills (default ~/.codex/skills). Each subfolder needs a SKILL.md with name and description frontmatter.
• After installing or updating a skill, restart Codex so it reloads metadata.
• In a session, describe the task naturally; Codex auto-triggers skills whose descriptions match the request. You can also mention a skill by name if you want it considered.
• To verify installation, list installed skills (ls ~/.codex/skills) and inspect metadata (head ~/.codex/skills/<skill>/SKILL.md).

Creating Skills

Skill layout:

skill-name/
├── SKILL.md          # Required: instructions + YAML frontmatter
├── scripts/          # Optional: helper scripts for deterministic steps
├── references/       # Optional: long-form docs loaded only when needed
└── assets/           # Optional: templates or files used in outputs

Basic SKILL.md template:

---
name: my-skill-name
description: What the skill does and when Codex should use it.
---

# My Skill Name

Clear instructions and steps for Codex to execute the task.

Best practices:

• Keep the description exhaustive about when to trigger; keep the body focused on execution steps.
• Use progressive disclosure: put detailed references in references/ and call them out from SKILL.md only when needed.
• Include scripts for repeatable or deterministic operations; mention when Codex should run them.
• Avoid extra docs (README, changelog) inside the skill folder to keep context lean.

Contributing

PRs welcome. Add real, reusable skills, keep descriptions precise, and include any needed scripts or references. If you add new skills, ensure the description clearly states when Codex should trigger and test that metadata fits within context limits.
