What is the purpose of YAML frontmatter in a command file?

YAML frontmatter is used to configure command metadata, such as the description shown in /help, the specific AI model to use, and the list of allowed tools like Read, Write, or Bash.

Can slash commands execute shell scripts?

Yes, slash commands support inline bash execution using the !`command` syntax, allowing you to fetch repository data or environment details to use as prompt context.

Where should I store my custom Claude Code commands?

Project-specific commands should be stored in the .claude/commands/ directory within your project, while global personal commands belong in ~/.claude/commands/.

How do I pass variables to a custom slash command?

You can use dynamic arguments like $1, $2, or $ARGUMENTS within your command's Markdown file. Claude replaces these placeholders with the input provided when you run the command.
