AGNXI is a directory platform for discovering and sharing agent skills (SKILL.md workflows) for AI coding tools. It aggregates 11.7k skills from the community, supports Claude, Cursor, Windsurf, Cline, Amp, and GitHub Copilot, and lets you browse, compare, and install skills to enhance your coding assistant.
What is AGNXI?
AGNXI is a web-based directory where developers can discover, share, and install SKILL.md workflows — structured instruction files that teach AI coding assistants specific capabilities. It indexes over 11,700 community-contributed skills, each with an author, description, install count, and date. The platform runs as a Next.js site hosted on Vercel and is maintained by the AGNXI team. Users can browse by category, author, or keyword, and one-click install skills into compatible assistants.
Key Features
- 11.7k+ community skills — A growing library of SKILL.md workflows for Claude, Cursor, Windsurf, Cline, Amp, and GitHub Copilot.
- Browse by category, author, or keyword — Skills are tagged with categories like QA, design, testing, and more. For example, garrytan’s QA skills have each been installed over 74k times.
- Featured skill listings — The homepage highlights recently added or popular skills with author avatars, descriptions, install counts, and dates (e.g., “cyrusse/use-skills” helps choose relevant installed skills for complex requests).
- One-click install — Each skill page provides an install button that integrates the workflow directly into supported coding assistants.
- SKILL.md format — Skills are plain-text markdown files that define a specific task, input/output expectations, and instructions for the AI assistant.
- Open ecosystem — Anyone can contribute a skill via GitHub; no central approval required.
Who is it for?
- AI coding assistant users — Developers using Claude Code, Cursor, Windsurf, Cline, Amp, or GitHub Copilot who want to add pre-built skills for tasks like QA testing, design review, cookie setup, or release documentation.
- Skill authors — Developers who create and share SKILL.md workflows to solve specific problems (e.g., garrytan’s QA suite includes skills for systematic testing, design review, and cookie import).
- Team leads — Engineering managers who want to standardize common agent instructions across their team by installing and maintaining a shared skill library.
What can you do with AGNXI?
- Install a QA testing skill — Use garrytan’s “qa” skill to systematically test a web app, find bugs, and fix them atomically. It runs tests, iteratively fixes issues, and produces before/after health scores.
- Add a design review skill — The “qa-design-review” skill visually checks spacing, typography, and interaction feel, then fixes code and re-verifies with screenshots.
- Set up browser cookies for testing — The “setup-browser-cookies” skill imports cookies from a real browser (Chrome, Arc, Brave, Edge) into a headless session for testing authenticated pages.
- Optimize AI prompts — The “Banana Prompts Optimizer” skill reverse-engineers images into precise Midjourney/Stable Diffusion prompts, and searches a large prompt library.
How does AGNXI work?
Users browse the directory, find a skill, and click install. The skill’s SKILL.md file is downloaded or injected into the user’s coding assistant. The assistant then follows the instructions in the skill when triggered by the appropriate command (e.g., /qa for QA testing). Skills can be updated by their authors and users can see install counts to gauge popularity.
FAQ
Is AGNXI free to use?
Yes, browsing and installing skills from the directory is free. There are no paid tiers — the directory is open and community-driven.
What kinds of skills are available?
Skills cover testing (QA, design review), browser automation (cookie setup, headless browsing), code upgrades (gstack-upgrade), documentation generation (document-release), and prompt engineering (Banana Prompts Optimizer). Over 11,700 skills are indexed.
How do I install a skill?
Navigate to a skill’s page on AGNXI and click the install button. The skill’s SKILL.md is automatically applied to your compatible coding assistant (Claude Code, Cursor, Windsurf, etc.).
Can I contribute my own skill?
Yes. Skills are hosted on GitHub and you can submit yours via the AGNXI website. Each skill is a SKILL.md file that defines instructions for the AI assistant.
Does AGNXI support all AI coding tools?
The platform explicitly supports Claude, Cursor, Windsurf, Cline, Amp, and GitHub Copilot. Other tools that can parse SKILL.md may also work, but these are the announced integrations.
