FAQPage Schema

How do I design Claude Code slash commands with preflight checks?▼

Build robust Claude Code slash commands by structuring frontmatter, preflight checks, context, task instructions, and success criteria. This ensures safe execution and maintainability.

When should I use slash commands instead of skills in Claude Code?▼

Use slash commands for structured, repeatable workflows requiring explicit frontmatter and tool restrictions. Use skills for broader, dynamic orchestration. Commands excel at concise, testable task execution.

How do I enforce tool restrictions in Claude Code command design?▼

Enforce tool restrictions in Claude Code command design by defining explicit rules within the command's frontmatter and task instructions. This prevents unauthorized tool usage during execution.

Can I use subagents for inter-skill orchestration in slash commands?▼

Yes, you can use subagents for safe inter-skill orchestration by guiding explicit Skill() and Task() invocations within your slash commands. This enforces structured delegation patterns.

What is the best way to structure frontmatter for Claude Code commands?▼

The best way to structure frontmatter for Claude Code commands is to define strict metadata fields specifying tool restrictions, preflight requirements, and delegation patterns for safe execution.
