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.

New plugin workflow:

Create with $plugin-creator
Validate with plugin-scanner — Required: score ≥ 80, no high/critical findings
Gate PRs with the HOL scanner GitHub Action — Required for listing
Ship or submit with confidence

Quick preflight

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
See contributing requirements: CONTRIBUTING.md
