CodexStacks for plugin authors

If you build a Codex plugin, skill or MCP connector, CodexStacks gives it a page with install steps, what it contains and where it comes from. Here's how to show you're listed, embed your listing and keep it accurate. Everything here is free.

1. Add the “Listed on CodexStacks” badge

Every listing page has a For maintainers section with a ready-made badge in Markdown and HTML that links to that listing. It's a small static SVG (https://codexstacks.com/badge.svg) with no tracking. For example, on the Figma page:

[![Listed on CodexStacks](https://codexstacks.com/badge.svg)](https://codexstacks.com/p/figma/)

2. Embed a listing card

Each listing page also has an embeddable card: plain HTML with inline styles, no JavaScript and no external requests except the link back to your listing. Paste it into your docs site, landing page or blog. There's a Markdown summary too, for READMEs where HTML styles are stripped. This is the card for Figma:

3. Update or fix your listing

In OpenAI's curated catalog? Your listing is rebuilt every night from openai/plugins, so a new version, new skills or a new description shows up here automatically. Changes are logged on New this week.
A community repo? Tag it codex-plugin on GitHub. We re-read your repo's manifest, description and stars every night; repos with at least 10 stars, a push in the last 180 days, a description and a manifest or README are listed automatically (full filter). Shipping .agents/plugins/marketplace.json gets you one-line install commands.
Something wrong? Use the Submit or improve this listing link at the bottom of your listing page. It opens the submit form filled in with what we have, so you only change what's wrong. We review every request by hand and reply from hello@codexstacks.com.

4. Follow what changes

Every new listing, newly qualifying repo, notable update and removal is published on /new/, in the RSS and Atom feeds, and as JSON. The weekly CodexStacks email covers the highlights.
