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:
Open Codex settings → Plugins → Next to search plugins input click on menu and select → +Add More...
Add this URL:
https://github.com/hashgraph-online/awesome-codex-plugins.git
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.
Third-party plugins built by the community. PRs welcome!

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 .

Use scanner outputs as evidence for maintainers/reviewers:
The score is best used as a quick trust signal and triage summary (not the only readiness signal).
Verify ownership of your plugin on the HOL Plugin Registry to display a verified badge on your listing.
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.
Each plugin gets a detailed breakdown across six factors:
You can embed a trust badge in your plugin's README:
[](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.
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.
