Gives you a reference guide for command syntax and usage when you're working in the terminal. You'd reach for this when you can't remember flags, need to verify options, or want to check how a command actually works without leaving your conversation. It's essentially man pages integrated into Claude, which is helpful when you're prototyping or troubleshooting and don't want to context switch. The main advantage is keeping everything in one place rather than jumping between your terminal, browser, and editor. Works best when you need quick lookups rather than learning a tool from scratch.
