YFGE Agent Plugins

Public Git-backed index marketplace for open-source agent plugins.

Codex remains the primary catalog format. The same plugin set is also indexed for Claude Code and Cursor, with OpenCode support provided through local/Git installable plugin wrappers and install notes.

This repository is not affiliated with OpenAI, Anthropic, Cursor, or OpenCode.

Install

Codex

Add this marketplace to Codex:

codex plugin marketplace add https://github.com/yfge/codex-plugins.git

Maintainers can use the SSH remote for pushing changes:

git@github.com:yfge/codex-plugins.git

Claude Code

The Claude Code marketplace index lives at .claude-plugin/marketplace.json.

Add this repository as a Claude Code plugin marketplace:

/plugin marketplace add yfge/codex-plugins

Cursor

The Cursor marketplace index lives at .cursor-plugin/marketplace.json.

Add this repository URL in Cursor's plugin marketplace or add-plugin flow:

https://github.com/yfge/codex-plugins.git

OpenCode

OpenCode does not consume the marketplace JSON files directly. Clone this repository and install the plugin wrapper from the plugin's .opencode/ directory.

For Feishu, see plugins/feishu/.opencode/INSTALL.md.

Browse Plugins

Open Codex in a project, then type:

/plugins

Choose YFGE Codex Plugins from the marketplace tabs, inspect a plugin, then install or enable it from the Codex plugin browser.

codex plugin marketplace upgrade yfge-codex-plugins

Remove the marketplace from Codex:

codex plugin marketplace remove yfge-codex-plugins

Validate

Run the repository checks before submitting changes:

npm test
npm run validate

The validator checks the Codex, Claude Code, and Cursor marketplace catalogs, plugin id consistency, external Git source descriptors, first-party runtime manifests, OpenCode wrappers, source paths, install policies, and duplicate plugin ids.

Add A Plugin

Prefer keeping plugin source code in its own public GitHub repository and adding only index entries to the runtime marketplace files. First-party plugins maintained with this marketplace may also live under plugins/<plugin-name>/ and be indexed with a local source in Claude Code/Cursor plus a git-subdir Codex entry pointing at this repository.

If the plugin lives in a subdirectory:

{
  "name": "your-plugin",
  "source": {
    "source": "git-subdir",
    "url": "https://github.com/your-org/your-plugin.git",
    "path": "./plugins/your-plugin",
    "ref": "main"
  },
  "policy": {
    "installation": "AVAILABLE",
    "authentication": "ON_INSTALL"
  },
  "category": "Productivity"
}

For a first-party plugin hosted in this repository:

{
  "name": "your-plugin",
  "source": {
    "source": "git-subdir",
    "url": "https://github.com/yfge/codex-plugins.git",
    "path": "./plugins/your-plugin",
    "ref": "main"
  },
  "policy": {
    "installation": "AVAILABLE",
    "authentication": "ON_INSTALL"
  },
  "category": "Productivity"
}

If the plugin lives at the repository root:

{
  "name": "your-plugin",
  "source": {
    "source": "url",
    "url": "https://github.com/your-org/your-plugin.git",
    "ref": "main"
  },
  "policy": {
    "installation": "AVAILABLE",
    "authentication": "ON_INSTALL"
  },
  "category": "Productivity"
}

Mirror the same plugin id in .claude-plugin/marketplace.json and .cursor-plugin/marketplace.json. For external repositories, keep Codex and Claude Code sources pinned with a branch/tag ref or commit sha; Cursor's current marketplace schema uses a string Git URL source. For first-party plugins, add:

plugins/<plugin-name>/
  .codex-plugin/plugin.json
  .claude-plugin/plugin.json
  .cursor-plugin/plugin.json
  .opencode/plugins/<plugin-name>.js

See CONTRIBUTING.md for the required layout and review checklist.
