hashgraph-online/awesome-codex-plugins

A curated list of awesome plugins, skills, and resources for OpenAI Codex and ChatGPT.

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.

Codex is now available inside the ChatGPT desktop app, while remaining a distinct coding workspace. OpenAI plugins can support workflows in ChatGPT, Codex, or both; this repository remains a Codex-compatible marketplace.

New plugin workflow:

1. Create with $plugin-creator
2. Validate with plugin-scanner. The catalog-owned centralized scan must report a normalized score ≥ 80/100 before merge.
3. Optionally gate your source repo with the HOL scanner GitHub Action. Catalog admission uses the centralized scan; source-repo scanner CI is recommended but not required.
4. Ship or submit with confidence

pipx run plugin-scanner lint .
pipx run plugin-scanner verify .

All plugins submitted to Awesome Codex Plugins must pass the HOL AI Plugin Scanner:

See contributing requirements: 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.

Install plugins directly from this curated list by pointing Codex at the repo marketplace:

CLI:

# 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 <plugin-name> --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.

Use the built-in skill to scaffold a new plugin:

$plugin-creator

Currently no self-serve marketplace submission. Plugins are distributed via local marketplaces (~/.agents/plugins/marketplace.json), repo marketplaces ($REPO_ROOT/.agents/plugins/marketplace.json), or GitHub repos by pointing a marketplace source at a repo. OpenAI has stated third-party marketplace submissions are coming soon.

For this curated list, the machine-readable source of truth is the generated repo marketplace at .agents/plugins/marketplace.json. We keep the README for humans and plugins.json as a compatibility export for existing automation.

After scaffolding with $plugin-creator, use plugin-scanner as your quality gate before publishing, review, or distribution.

For skill/plugin authoring workflows, Codex SkillForge provides an ESLint-style CLI and GitHub Action for scaffolding, linting, smoke-testing, and packaging Codex skills/plugins before publishing.

pipx run plugin-scanner lint .
pipx run plugin-scanner verify .

- uses: hashgraph-online/ai-plugin-scanner-action@v1
  with:
    plugin_dir: "."
    fail_on_severity: high

Use scanner outputs as evidence for maintainers/reviewers:

• Structural lint results
• Publish-readiness verification output
• SARIF/findings for CI and code scanning

The score is best used as a quick trust signal and triage summary (not the only readiness signal).

• Codex v0.117.0 Plugin Walkthrough - Reddit explainer.

Verify ownership of your plugin on the HOL Plugin Registry to display a verified badge on your listing.

1. Go to hol.org/guard/plugins and sign in with GitHub
2. Find your plugin in the list and click Verify Ownership
3. Authorize the read-only GitHub connection (view your profile, email, and public org membership — no write access)
4. Once verified, your plugin listing will display a Verified badge

That's it. The verification confirms you are the repository owner or an organization admin. Plugins owned by organizations may require additional review.

Note: You only need to verify once per plugin. If your verification needs to be reset, contact support at support@hol.org.

Every plugin in this list is automatically ingested by the HOL Plugin Registry, which runs each through the plugin-scanner to produce a trust score and security analysis.

A snapshot of scored installable plugins (plus modeled Guard runtime fixtures and public advisories) is published on Hugging Face as HOL Plugin Security. Scan ≠ safety guarantee. Catalog plugin count is not the Registry Broker agent catalog. HOL publishes it; not independent validation. Cite this curated list with CITATION.cff.

Each plugin gets a detailed breakdown across six factors:

• Installability - Can the plugin be installed and run without errors?
• Maintenance - Is the repo actively maintained with clear documentation?
• MCP Posture - How securely are MCP servers configured?
• Plugin Security - Does the manifest follow security best practices?
• Provenance - Can the publisher's identity be verified?
• Publisher Quality - Does the publisher have a track record of quality releases?

You can embed a trust badge in your plugin's README:

[![Plugin Name on HOL Registry (Trust Score)](https://img.shields.io/endpoint?url=https%3A%2F%2Fhol.org%2Fapi%2Fregistry%2Fbadges%2Fplugin%3Fslug%3DOWNER%252FREPO%26metric%3Dtrust%26style%3Dfor-the-badge%26label%3DPlugin+Name)](https://hol.org/registry/plugins/OWNER%2FREPO)

Replace OWNER%2FREPO with your plugin's GitHub owner and repo name (URL-encoded slash). Metrics available: trust, security. Styles: flat, flat-square, plastic, for-the-badge, social.

Show that your plugin repo is protected by HOL Guard:

[![HOL Guard](https://img.shields.io/endpoint?url=https%3A%2F%2Fhol.org%2Fapi%2Fregistry%2Fbadges%2Fguard%2FOWNER%2FREPO%3Fstyle%3Dflat-square)](https://hol.org/guard)

The badge checks your repo for HOL Guard adoption (config files, CI workflows, dependencies) and displays Protected (green) or Unprotected (grey). To get the badge:

1. Install HOL Guard: pipx install hol-guard && hol-guard init
2. Or add the scanner to CI: uses: hashgraph-online/ai-plugin-scanner-action@v1
3. Add the badge markdown to your README (replace OWNER%2FREPO)

If you received a scanner report on your repo, check the Scanner Guide for setup instructions, common fixes, and CI setup.

Contributions welcome! Please read the contribution guidelines first.

To add a plugin:

1. Optionally set up the HOL Plugin Scanner in your plugin repo for source-side feedback (see CONTRIBUTING.md); the catalog-owned centralized scan is authoritative for admission
2. Fork this repo and add a single line to the appropriate section in README.md (alphabetical order)
3. Submit a PR with the plugin repo URL; include a local or source-CI scanner score when available

You do not need to copy plugin files into this repo. A generator fetches your bundle from your source repo and regenerates catalog files automatically.
