Run

This executes shell commands directly from Claude's context, giving you programmatic access to your terminal without context switching. You'd reach for this when you need to run scripts, check system status, or chain command outputs into further analysis. The real utility is keeping everything in one conversational flow instead of bouncing between chat and terminal. It's straightforward command execution with stdout/stderr capture, so it works best for quick operations rather than long-running processes. Think of it as giving Claude hands on your keyboard for those moments when you're describing what you want to run anyway.
