New plugin workflow:

  1. Create with $plugin-creator
  2. Validate with codex-plugin-scanner
  3. Gate PRs with the HOL scanner GitHub Action
  4. Ship or submit with confidence

Quick preflight:

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

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:

# 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...

    image

  2. Add this URL:

    https://github.com/hashgraph-online/awesome-codex-plugins.git
    image

  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.

Plugin Creator

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

$plugin-creator

Publishing

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.

Validate Before You Ship

After scaffolding with $plugin-creator, use codex-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.

Local Preflight

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

PR Gate (GitHub Actions)

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

Submission Preflight

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).

Guides & Articles

Plugin Trust Scores

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

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.

Plugin Quality

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