This repository serves as a curated marketplace for OpenAI Codex plugins, skills, and resources, targeting Codex users and developers. It provides a centralized, reproducible source for plugins, simplifying discovery and integration within the Codex ecosystem.

How It Works

This project acts as a decentralized marketplace for installable plugin bundles, publishing a marketplace.json file pointing to mirrored assets in ./plugins/. Users add this Git repository as a Codex marketplace source for direct installation. This ensures faster, reliable installations and reproducible plugin versions, independent of upstream availability.

Quick Start & Requirements

• Primary install / run command:
  • CLI: Add repo as marketplace: codex plugin marketplace add 'https://github.com/hashgraph-online/awesome-codex-plugins.git' --ref 'main' --sparse '.agents/plugins' --sparse 'plugins'. Then list/install: codex plugin list --source awesome-codex-plugins.
  • Desktop/IDE: Add https://github.com/hashgraph-online/awesome-codex-plugins.git in Codex settings → Plugins → +Add More...
• Non-default prerequisites: OpenAI Codex environment. pipx recommended for plugin-scanner. Some plugins may have specific language/OS requirements.
• Links: Live Registry: https://hol.org/registry/plugins; Dev Guides: https://github.com/hashgraph-online/awesome-codex-plugins#plugin-development; HOL Registry: https://hol.org/registry/plugins.

Highlighted Details

• Extensive Plugin Catalog: Official OpenAI-curated plugins (e.g., GitHub, Google Drive, Slack) and numerous community plugins across AI development, DevOps, data analysis, and productivity.
• Automated Quality & Trust Scoring: HOL Plugin Registry uses plugin-scanner for trust scores and security analyses (installability, maintenance, security posture, provenance, publisher quality).
• Reproducible Distribution: Plugins are mirrored within the repo, ensuring consistent installation versions and reducing reliance on external sources.
• Developer Tooling: Scaffolding ($plugin-creator), linting (plugin-scanner), and validation tools aid in creating and publishing high-quality Codex plugins.

Maintenance & Community

The project welcomes community contributions via pull requests. While specific maintainer details or direct community channels are not listed, the extensive catalog and related projects suggest an active ecosystem. Distribution and collaboration primarily occur via GitHub.

Licensing & Compatibility

The specific open-source license is not explicitly stated, posing a significant adoption concern, especially for commercial use. Compatibility is primarily for OpenAI Codex, with many plugins also supporting Claude Code, Cursor, and MCP servers.

Limitations & Caveats

The lack of a defined license is a primary adoption blocker. The ecosystem appears rapidly evolving, with potential for API changes or deprecations. Some plugins may have specific, unlisted dependencies or platform requirements (e.g., macOS-only features).
