Useful Agent Skills Repos

Big repositories / collections

  • Large cross-agent collection with 1000+ agent skills, compatible with Claude Code, Codex, Gemini CLI, Cursor, and others.
  • Curated list focused on real-world skills used by engineering teams, supporting Claude, Copilot, Codex, Cursor, and Windsurf.
  • Anthropic’s public repo demonstrating skills across technical, creative, and enterprise workflows.
  • Microsoft’s collection covering skills, MCP servers, custom agents, and AGENTS.md templates, includes around 132 skills.
  • Focused on practical web and frontend/dev workflows, structured around SKILL.md with optional scripts and references.
  • More of a workflow framework than a raw skill pack, built around composable skills and reusable instructions.
  • Opinionated, production-oriented engineering skills with progressive disclosure via SKILL.md.

Useful smaller / niche repos

  • Covers broader use cases beyond coding, including macOS apps, MCP deployment, and connectors.
  • Curated list of Claude-specific skills and resources.
  • Smaller repo, useful for understanding how skills are structured and packaged.
  • Additional examples of SKILL.md usage, decision logic, and references in practice.
  • המאגר כולל כיום כ-150 סקילים ו-39 שרתי MCP ב-12 קטגוריות שונות ובהן מיסוי, שירותים ממשלתיים, בריאות, משפטים וחינוך
  • A Claude Code skill/plugin and Codex plugin that makes agent talk like caveman — cutting ~75% of output tokens while keeping full technical accuracy.
  • Hyperframes is an open-source video rendering framework that lets you create, preview, and render HTML-based video compositions — with first-class support for AI agents.
    • It is mostly a local HTML-to-video renderer. You write HTML compositions, preview them in a browser, then render them to MP4/MOV/WebM on your own machine or in a container.
    • You only need the skill if you want an AI coding agent to do more of the composition work for you. If you are comfortable writing HTML/CSS/JS yourself, you can use HyperFrames directly through the CLI and studio.
  • Browser automation tool for AI coding agents, with a few different ways to run depending on whether you want isolation, Playwright-controlled browser sessions, or to work against your own real browser.
    • Runs browser scripts in a sandboxed QuickJS runtime, so the agent is not just getting raw unrestricted Node.js execution
    • Can work in a more isolated disposable mode when you want safer, cleaner runs without touching your normal browsing session
    • Can also attach to your own browser/tabs, which is useful when you want the agent to continue work inside a real logged-in session instead of a throwaway browser context
