What it solves

This project provides a centralized, curated marketplace for plugins and skills designed for OpenAI Codex and ChatGPT. It solves the problem of discovering, verifying, and installing reliable third-party tools that extend the functionality of the Codex coding environment.

How it works

Users can add this repository as a marketplace source within the Codex CLI, desktop app, or IDE extension. The repository includes a marketplace.json file that points to mirrored plugin bundles, ensuring fast and reproducible installations. To maintain quality and security, all community-submitted plugins must pass a mandatory centralized scan (via the plugin-scanner tool) and achieve a normalized trust score of at least 80/100 before being accepted into the catalog.

Who it’s for

This is for developers and power users of OpenAI Codex who want to enhance their coding workflows with specialized agents, automation tools, and productivity plugins while ensuring those tools meet specific quality and safety standards.

Highlights

• Curated marketplace of official and community-contributed plugins.
• Mandatory security and quality scanning for all community submissions.
• Easy integration with Codex CLI and desktop interfaces via Git-based marketplace sourcing.
• Includes a wide variety of tools for project management, security auditing, agent orchestration, and developer productivity.
• Supports reproducible, offline-ready installations by mirroring plugin bundles directly in the repository.
