Can I use shell commands inside my custom Claude commands?

Yes, you can use bash execution by prefixing backticks with an exclamation mark to include real-time terminal output in your command's context.

Where should I store my custom command files?

Project-specific commands go in .claude/commands/, while personal commands for all your projects should be stored in ~/.claude/commands/.

What is the difference between a Claude Command and a Skill?

Commands are user-initiated via a slash (e.g., /review), whereas Skills are automatically triggered by the model based on the conversation context.

How do I pass arguments to a custom slash command?

You can use $1, $2, or $ARGUMENTS within your command file to capture inputs provided by the user when they invoke the command.

Is it possible to limit what tools Claude can use during a command?

Yes, the allowed-tools field in the command's YAML frontmatter allows you to strictly define which capabilities, like Bash, Read, or Write, Claude can access.
