Knowledge Work Plugins

OpenAI Plugins is a curated repository of Codex plugin examples, maintained as a directory of independently packaged plugins and marketplace manifests. Each plugin has a required `.codex-plugin/plugin.json` manifest and may include skills, app and MCP configuration, agents, commands, hooks, assets, and other supporting files. The repository's standard and API-key-login marketplaces index the available plugins, including examples for Figma, Notion, iOS and macOS development, web apps, Expo, Netlify, Remotion, and Google Slides.

A community plugin marketplace for Claude Cowork and Claude Code, maintained by Anthropic as a read-only mirror of Anthropic’s community plugin directory. Its `.claude-plugin/marketplace.json` manifest lists plugins available for installation; submissions enter Anthropic’s review pipeline, undergo automated security scanning, and are approved before being synchronized to the repository nightly. Claude Cowork users install plugins through `claude.com/plugins`, while Claude Code users can add the marketplace with `claude plugin marketplace add anthropics/claude-plugins-community` and install listed plugins through the CLI. Plugin submissions are made through Anthropic’s submission flow rather than by pull requests to the mirror.

Agent Plugins for AWS is an AWS Labs collection of plugins for AI coding agents, helping them architect, deploy, and operate on AWS. Supported agents include Claude Code, Codex, and Cursor. Each plugin can package agent skills—structured workflows and best-practice playbooks—alongside MCP servers that provide access to live documentation, pricing data, and other APIs; hooks that validate changes or trigger workflows; and references containing documentation and configuration defaults. The repository describes the plugins as reusable, versioned capabilities intended to reduce prompt context and standardize agent behavior. It warns that generative AI can make mistakes and recommends reviewing generated code, costs, security, and credentials. The repository also identifies Agent Toolkit for AWS as the successor for production use, while stating that this project continues to work and accept contributions.

Everything Claude Code is a Claude Code plugin and toolkit containing configurable agents, skills, slash commands, rules, hooks, contexts, MCP server configurations, scripts, and tests for AI-assisted software development. Its agents delegate tasks such as planning, code review, security review, testing, and build-error resolution. Skills define workflows including test-driven development, security review, continuous learning, and verification; hooks run on Claude Code tool or session events to load and save context, suggest compaction, and evaluate sessions; and rules provide persistent guidance for security, coding style, testing, Git workflow, delegation, and performance. Node.js scripts support Windows, macOS, and Linux and detect a project's preferred package manager from environment settings, project configuration, package.json, lock files, or global configuration. The repository can be installed as a Claude Code plugin or copied into Claude configuration directories manually. It includes a Node.js test suite and is distributed under the MIT license.

Open Pstack is an unofficial, plugin-based workflow kit that brings Lauren Tan's pstack to Claude Code and Codex. It gives coding agents engineering rules, task-specific workflows, focused skills, and small local tools rather than providing a new model or hosted service. Its main poteto-mode workflow reads a task, selects an appropriate workflow, learns how the existing system works, compares designs when needed, favors small changes, and can use multiple models to challenge important decisions. It runs the code and checks behavior as a user would instead of stopping at passing tests, then can continue through review and continuous integration to prepare a pull request. Additional skills cover system explanation, architectural decisions, competing implementations, design interrogation, verification-skill creation and maintenance, pull-request supervision, and reflection. The repository supports installation as a Claude Code or Codex plugin and shares the same skill set between those applications. It is distributed under the MIT license and tracks the upstream pstack project while adapting its skills for Claude Code and Codex.
