About this site
Overview
This site is an independent catalog covering only the plugins and skills listed on the official Claude Code and Codex marketplaces. By deliberately limiting its scope to official listings, it gives a simple answer to one question: what is officially available. Unofficial plugins and skills that are not listed on the official marketplaces are not included. It centers on a running changelog of upstream additions, removals and changes, plus explanations grounded in primary sources.
Data sources
Claude Code plugin metadata comes from the anthropics/claude-plugins-official marketplace.json. Claude Code skill metadata comes from the anthropics/skills repository (SKILL.md frontmatter). Both are fetched daily at pinned commit SHAs. Skill instructions are never reproduced or fully translated; we show a summary and a link to the source. Codex plugin metadata comes from the openai/plugins marketplace.json and each plugin's .codex-plugin/plugin.json, likewise fetched daily at a pinned commit SHA. Listings correspond to the plugins and skills registered in each marketplace. Individual skills bundled inside a plugin (SKILL.md files) are not listed as separate entries, and plugin explanations stay at the plugin level rather than digging into bundled skill contents.
How the content is made
Short descriptions are AI-generated summaries based on the primary sources. Longer explanations are generated automatically by an AI model from primary sources (homepages, READMEs, SKILL.md) — there is no per-item human review before publishing. If we notice an issue afterwards, we may manually correct or freeze an entry, and any such entry is marked as possibly out of date if upstream changes again. Each explanation lists the sources it draws on and the dates they were fetched.
A note on installing plugins
More plugins is not always better: every installed plugin consumes part of the agent's context window. Install only what you actually use.
