9 Free "AI Skills" and "Plug-ins" That Feel Like Cheat Codes - Matt Wolfe, YouTube

In this video, creator Matt Wolfe breaks down how to leverage "skills" and "plugins"—which are essentially reusable instruction files, advanced prompts, or bundled configurations—across popular AI developer environments and agent harnesses like OpenAI's Codeex and Anthropic's Claude Code. Instead of just adding context, these free tools instill repeatable, specialized behaviors in an AI agent. Wolfe highlights a variety of practical tools, starting with GStack from Y Combinator's Gary Tan, which transforms an AI into an entire virtual engineering team. He also highlights Stop Slop for stripping out generic "AI-isms" from text, and Last 30 Days for running deep, real-time sentiment research across the web. The video also explores highly visual and creative AI utilities. Wolfe demonstrates Graphify and Understand Anything, two tools that map complex codebases or personal knowledge databases into queryable, interactive knowledge graphs to significantly lower token costs and improve engineering onboarding. Finally, he compares specialized aesthetic enhancers like Anthropic's Front-End Design and the Taste skill for UI refinement, alongside animation tools like Remotion and HeyGen's Hyperframes, which write code to automatically generate motion graphics, video charts, and logo reveals from simple text prompts.
