How do I pass arguments to a custom command?

You can use '$ARGUMENTS' to capture the entire input string or positional variables like '$1', '$2', and '$3' to reference specific words provided after the command.

Can I restrict which tools a custom command can access?

Yes, you can define the 'allowed-tools' field in the command's YAML frontmatter to specify exactly which tools (like Read, Write, or Bash) the command is permitted to use.

Where should I store my custom Claude Code commands?

Project-specific commands go in '.claude/commands/', while personal commands available across all projects should be stored in '~/.claude/commands/'.

What is the correct way to write instructions in a command file?

Commands should be written as direct instructions for Claude (the agent), not as messages for the human user. Focus on telling the AI exactly what actions to perform.
