Open source AI agent skills and developer tools for Claude, Cursor, an

Hi, I'm Jeremy! I'm a Columbus, Ohio-based developer (working remotely for SF companies) with 230+ repositories and nearly 8,000 GitHub contributions this past year. I create open source AI agent skills that help developers work more effectively with tools like Claude Code, Cursor, and OpenCode. My most popular project, agent-nestjs-skills, provides NestJS best practices optimized for AI assistants. Your support helps me keep these tools free, maintained, and constantly improving!
