# Plugins, agents, and skills for AI coding tools
Use one collection of plugins, agents, skills, and commands across Claude Code, OpenAI Codex CLI, Cursor, OpenCode, Antigravity CLI, GitHub Copilot, and Pi. A harness is the coding tool that loads and runs the components. Plugins cover Python and JavaScript development, code review, testing, infrastructure, security, and other work.
The catalog contains 94 plugins, including 92 local plugins and 2 external entries. The local source contains 202 agents, 185 skills, and 105 commands. The components share a Markdown source, with installation and capabilities adapted to each harness.
## Multi-harness support
Choose the harness you use and follow its setup route. Available components depend on the installation route and the harness's capabilities.
| Tool | Installation | Components and limits |
|---|---|---|
| Claude Code | Plugin marketplace | Source agents, skills, and commands; plugin-specific hooks and MCP configuration |
| OpenAI Codex CLI | Native marketplace or generated artifacts | Native source skills; generated TOML agents and commands as skills use a separate route |
| Cursor | Plugin marketplace | Source agents, skills, and commands, with curated project rules |
| OpenCode | `make install-opencode` | Generated agents, skills, and commands, with translated tool permissions |
| Antigravity CLI | `make install-antigravity` | Generated plugins containing agents, skills, and commands |
| GitHub Copilot | `make install-copilot` | Generated agent profiles and skills; commands also become invocable skills |
| Pi | `make install-pi` | Generated skills and prompt templates; agents require a subagent extension |
See the capability matrix for model mappings, tool permissions, hooks, and installation differences.
For individual skills, use a skills-only installer and select your coding tool.
## Quick start
Choose a plugin for the work you do:
| Plugin | Use it for |
|---|---|
| python-development | Python, Django, FastAPI, testing, and packaging |
| javascript-typescript | JavaScript and TypeScript development and project setup |
| developer-essentials | Code review, debugging, Git, and testing patterns |
| security-scanning | Security review, dependency checks, and code scanning |
See the plugin catalog for all 94 plugins and the usage guide for commands and examples.
### Claude Code
Run these commands inside Claude Code to register the marketplace and install the Python development plugin:
 [code] 
Then ask Claude to use the Python agents for your task, or run the plugin's scaffolding command:
 [code] 
### Codex CLI
Run these commands in a terminal with a current Codex CLI:
 [code] 
The native Codex manifests expose source skills. The generated TOML agents and command-derived skills use a separate adapter path. Native installation also reads the original skill bodies, while generated copies split oversized bodies into reference files for the 8 KB budget. See the Codex setup details before choosing an
