What it is

awesome-claude-skills is a curated list of Claude Skills and plugins grouped into categories such as Document Processing, Development & Code Tools, Data & Analysis, Business & Marketing, and more. Skills are reusable instruction packages: folders with a SKILL.md file (YAML frontmatter plus Markdown instructions), optionally with scripts, references and assets. The README also offers a connect-apps plugin that uses Composio to let Claude take actions across 1000+ apps.

Who it's for

  • Users of Claude.ai, Claude Code, or the Claude API who want ready-made skills
  • Developers using other coding agents named in the README (Codex, Cursor, Gemini CLI, Antigravity, Windsurf)
  • People wanting Claude to take real actions in apps such as email, Slack, and GitHub issues
  • Contributors who want to create or submit their own skills

Requirements

Requirements

  • Claude Code CLI (the quickstart uses the claude command)
  • A Composio API key (the README says a free key is available) for the connect-apps plugin

Setup

  1. Install the connect-apps plugin

    Start Claude Code with the plugin directory.

    bash
    claude --plugin-dir ./connect-apps-plugin

  2. Run setup

    bash
    exit

Pros & cons

Pros

  • Pro:Large catalog organized into clear categories (documents, dev tools, data, marketing, creative, productivity, collaboration)
  • Pro:Many entries link directly to source repos, with author attribution
  • Pro:Skills format is documented as supported across Claude Code, Claude.ai, Claude API, Codex, Cursor, Gemini CLI, Antigravity and Windsurf
  • Pro:Includes a quickstart plugin for taking real actions in apps like Gmail, Slack and GitHub

Cons

  • Con:The action-taking quickstart depends on Composio and an API key from its dashboard
  • Con:It is a list of links, so quality and setup steps depend on each linked project
  • Con:The provided README text is truncated, so later sections (Getting Started, Creating Skills, Contributing) are not visible
