You'll use this whenever you find yourself typing the same prompts into Claude Code repeatedly. It lets you create shortcuts with the `/command` syntax that can run bash commands first, pull in file contents with `@` references, and accept arguments. The distinction from skills is straightforward: slash commands are for quick templates you trigger manually, while skills are for complex workflows Claude discovers automatically. Most useful for things like commit message generators that grab git status, code review checklists that reference your style guide, or refactoring prompts that need specific file context. Store them in `.claude/commands` for project-specific ones or `~/.claude/commands` for personal shortcuts you want everywhere.
