composiohq/awesome-codex-skills

This is a community-curated collection of skills for Codex, OpenAI's AI coding agent available through the Codex CLI. A skill is a reusable instruction bundle stored in its own folder that tells Codex how to handle a specific type of task. Each skill includes metadata (a name and description) plus step-by-step guidance. When you describe a task to Codex, it reads skill metadata to find a match, then loads the relevant instructions and follows them. The collection covers several categories. Development and code tools include skills for PR review, CI failure diagnosis, large codebase migrations, codebase history analysis, deployment pipelines, and more. Productivity and collaboration skills handle meeting transcript summaries, task management in Linear and Jira, internal communications, and document organization. There are also communication and writing skills, data analysis skills, and utility skills for tasks like managing other skills. Some skills connect Codex to external services. A section called Connect uses the Composio CLI to wire Codex to over 1,000 apps such as Slack, GitHub, Notion, and Jira, so the agent can take real actions inside those tools rather than just generating text. Skills are installed by copying a folder into a specific directory on your machine (by default ~/.codex/skills/) and restarting Codex. The repository includes a Python script that automates this fetching and placement. The collection is maintained by Composio, a company building integration tooling for AI agents, and accepts contributions from the community. Several third-party skill collections are also listed, covering areas like AI code review, security auditing, and larger product-building frameworks.
