Codex CLI Skills

If you want Codex CLI skills that are easy to install and practical in a local coding loop, this repository is designed for that exact use case.

Antigravity Awesome Skills supports Codex CLI through the .codex/skills/ path and gives you a wide set of reusable task playbooks for planning, implementation, debugging, testing, security review, and delivery.

How to use Antigravity Awesome Skills with Codex CLI

Install the library into your Codex path, then invoke focused skills directly in your prompt. The most common pattern is:

1. install with npx antigravity-awesome-skills --codex
2. choose one workflow-oriented skill such as @brainstorming, @concise-planning, or @test-driven-development
3. ask Codex to apply that skill to a concrete file, feature, test, or bugfix

Why use this repo for Codex CLI

• It supports Codex CLI with a dedicated install flag and a standard skills layout.
• It is strong for local repo work where you want to move from planning to implementation to verification without changing libraries.
• It includes both general-purpose engineering skills and deeper specialist tracks.
• It gives you docs and bundles, not just raw skill files.

Install Codex CLI Skills

npx antigravity-awesome-skills --codex

If you prefer a plugin-style Codex integration, this repository also ships repo-local plugin metadata in .agents/plugins/marketplace.json and plugins/antigravity-awesome-skills/.codex-plugin/plugin.json.

It also generates bundle-specific Codex plugins so you can install a curated pack such as Essentials or Web Wizard as a marketplace plugin instead of loading the full library.

Those Codex plugins are plugin-safe filtered distributions. Skills that still depend on host-specific paths or undeclared setup stay in the repository, but are not published into the Codex plugin until they are hardened.

Verify the install

test -d .codex/skills || test -d ~/.codex/skills

Best starter skills for Codex CLI

• brainstorming: clarify requirements before touching code.
• concise-planning: turn ambiguous work into an atomic execution plan.
• test-driven-development: structure changes around red-green-refactor.
• lint-and-validate: keep quality checks close to the implementation loop.
• create-pr: wrap up work cleanly once implementation is done.

Example Codex CLI prompts

Use @concise-planning to break this feature request into an implementation checklist.

Use @test-driven-development to add tests before changing this parser.

Use @create-pr once everything is passing and summarize the user-facing changes.

What to do next

• Read ai-agent-skills.md if you want a framework for choosing between broad and curated skill libraries.
• Use workflows.md when you want step-by-step execution patterns for common engineering goals.
