This repository provides a curated collection of practical "Codex skills" designed to extend the capabilities of the Codex CLI and API beyond simple text generation. It targets developers and power users seeking to automate complex workflows, enabling actions like sending emails, managing GitHub issues, posting to Slack, and interacting with over 1000 applications via the Composio integration. The primary benefit is enhanced automation and task execution within the Codex ecosystem.

How It Works

Codex skills are modular, self-contained units residing in individual folders. Each skill includes a SKILL.md file containing YAML frontmatter (name, description) and step-by-step instructions. Codex utilizes this metadata to intelligently trigger the appropriate skill based on user prompts. The Composio integration is central to enabling real-world actions across numerous third-party applications, moving beyond purely generative tasks.

Quick Start & Requirements

• Installation: Clone the repository and use the provided skill-installer/scripts/install-skill-from-github.py script, specifying the desired skill's GitHub path, or manually copy skill folders into the $CODEX_HOME/skills directory (defaults to ~/.codex/skills).
• Prerequisites: Requires the Codex CLI/API. Python is needed for the installer script.
• Setup: Restart the Codex application after installing or updating skills for them to be recognized.
• Links: Community Discord, X updates, support@composio.dev.

Highlighted Details

• Extensive integration with GitHub for code review and CI/CD tasks.
• Productivity and collaboration skills for managing issues in Linear, capturing knowledge in Notion, and analyzing meeting insights.
• Communication skills for drafting emails, generating changelogs, and researching content.
• Data analysis skills, including spreadsheet formula generation and competitive ad extraction.
• Enables actions across 1000+ apps via the Composio platform.

Maintenance & Community

The project encourages community contributions via pull requests. Updates and new features are shared on X, and developers can engage with others via a dedicated Discord server. Direct support is available via email.

Licensing & Compatibility

The repository's license is not explicitly stated in the provided README. Users should verify licensing terms before integrating into commercial or closed-source projects.

Limitations & Caveats

This repository is a collection of skills for the Codex platform and requires the Codex CLI/API to function. Functionality for many skills, particularly those interacting with external services, depends on a configured Composio connection. New skills require a Codex restart to become active.
