AI agents are only as good as the instructions you give them. Skill Issue is where you find those instructions. We indexed 50,000+ skill files from GitHub and built a place to browse, build, and share them. Pick a skill for Claude, ChatGPT, Gemini, Cursor, or whatever you use. Copy the .md file. Your agent gets better at that thing immediately. There's also a builder if you want to make your own from scratch. Everything is free.
