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, 184 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:

/plugin marketplace add wshobson/agents
/plugin install python-development@claude-code-workflows

Then ask Claude to use the Python agents for your task, or run the plugin's scaffolding command:

/python-development:python-scaffold Create a FastAPI service with tests

Codex CLI

Run these commands in a terminal with a current Codex CLI:

codex plugin marketplace add wshobson/agents
codex plugin add python-development@claude-code-workflows
