OpenAI documents plugins and skills for Codex, packaging skills, MCP servers, and app integrations into shareable, installable bundles across the Codex app, CLI, and IDE extensions. ## Contents - [Start Here](#start-here) - [Official Plugins](#official-plugins) - [Community Plugins](#community-plugins) - [Plugin Development](#plugin-development) - [Guides & Articles](#guides--articles) - [Related Projects](#related-projects) --- ## Start Here New plugin workflow: 1. Create with `$plugin-creator` 2. **Validate with [`plugin-scanner`](https://github.com/hashgraph-online/hol-guard)** — **Required: score ≥ 80, no high/critical findings** 3. **Gate PRs with the [HOL scanner GitHub Action](https://github.com/hashgraph-online/ai-plugin-scanner-action)** — **Required for listing** 4. Ship or submit with confidence ### Quick preflight ```bash pipx run plugin-scanner lint . pipx run plugin-scanner verify . ``` ### Scanner Requirements (Mandatory for This List) All plugins submitted to **Awesome Codex Plugins** must pass the HOL AI Plugin Scanner: | Requirement | Threshold | |-------------|-----------| | **Score** | ≥ 80 / 130 | | **Severity** | No critical or high findings | | **CI** | Scanner must run in your repo's GitHub Actions | See the full guide: [`SCANNER_GUIDE.md`](./SCANNER_GUIDE.md) See contributing requirements: [`CONTRIBUTING.md`](./CONTRIBUTING.md) This repo publishes a Codex repo marketplace at `.agents/plugins/marketplace.json`. The marketplace points at mirrored installable plugin bundles under `./plugins/`, so a clone of this repo can act as a curated plugin source in Codex. ### Use this marketplace in Codex Install plugins directly from this curated list by pointing Codex at the repo marketplace: **CLI:** ```bash # Add this repo as a marketplace source (one-time setup) codex plugin marketplace add \ 'https://github.com/hashgraph-online/awesome-codex-plugins.git' \ --ref 'main' \ --sparse '.agents/plugins' \ --sparse 'plugins' # Then browse and install (the marketplace name is derived from the repo name) codex plugin list --source awesome-codex-plugins codex plugin install --source awesome-codex-plugins ``` Do not use the raw `marketplace.json` URL with `codex plugin marketplace add`. The Codex marketplace command clones a Git repository, so a raw GitHub file URL is treated like a repo URL and fails with `remote: 404: Not Found`. **Desktop App / IDE Extension:** 1. Open Codex settings → Plugins → Next to search plugins input click on menu and select → `+Add More...` 2. Add this URL: ``` https://github.com/hashgraph-online/awesome-codex-plugins.git ``` 3. The curated plugin list appears as an available marketplace source. Each plugin entry includes a `source.path` pointing at a mirrored bundle under `./plugins/` in this repo, so installations are fast and reproducible without hitting upstream repos at install time. ## Official Plugins Curated by OpenAI — available in the built-in Codex Plugin Directory - Box - Access and manage files. - Cloudflare - Manage Workers, Pages, DNS, and infrastructure. - Figma - Inspect designs, extract specs, and document components. - GitHub - Review changes, manage issues, and interact with repositories. - Gmail - Read, search, and compose emails. - Google Drive - Edit and manage files in Google Drive. - Hugging Face - Browse models, datasets, and spaces. - Linear - Create and manage issues, projects, and workflows. - Notion - Create and edit pages, databases, and content. - Sentry - Monitor errors, triage issues, and track performance. - Slack - Send messages, search channels, manage conversations. - Vercel - Deploy, preview, and manage Vercel projects. ## Community Plugins Third-party plugins built by the community.
