Can I prevent Claude from running a command automatically?

Yes, by setting 'disable-model-invocation: true' in the command frontmatter, you ensure the command can only be triggered manually by the user.

Why can't I use short model names like 'haiku' in commands?

Commands are passed directly to the API, which only recognizes version aliases (e.g., claude-haiku-4-5) or full IDs. Short aliases are only supported in Agents.

When should I use a Command instead of a Skill?

Use a Command when you need a specific, user-triggered workflow that accepts arguments. Use a Skill for context-aware, 'always-on' assistance that triggers automatically.

Where do I save my custom command files?

Project-level commands should be saved in '.claude/commands/your-command.md', while user-level commands go in '~/.claude/commands/'.

How do I handle multiple inputs in a command?

You can use positional variables like $1, $2, or $3 for specific arguments, or use $ARGUMENTS to capture the entire input string as one variable.

Productivity & Workflow

Streamlines the creation and validation of custom Claude Code slash commands for automated and parameterized workflows.

The Claude Command Builder skill is a specialized utility designed to help developers extend the Claude Code environment by creating robust, custom slash commands. It provides expert guidance on command architecture, ensuring users choose the right component type (Command vs. Skill vs. Agent) and follow strict schema requirements. By enforcing best practices for YAML frontmatter, argument handling, and tool selection—while providing critical warnings about model naming conventions to prevent API errors—this skill enables the creation of powerful, project-specific automations like custom git workflows, test runners, and scaffolding tools.
