What is a Claude Code Skill?

A Claude Code Skill is a specialized capability that provides domain-specific guidance and implementation patterns to enhance Claude's behavior during coding tasks.

Does this skill follow official Anthropic guidelines?

Yes, it incorporates best practices from official Anthropic documentation, the Agent SDK, and the Claude Cookbooks to ensure technical compliance.

How does the Skill Builder automate the creation process?

It uses a sequence of specialized agents—Prompt-Writer, Architect, Builder, Reviewer, and Tester—to move from an initial idea to a validated, production-ready skill.

Can I use this to build slash commands?

Absolutely. The Skill Builder supports the creation of standard skills, specialized agents, slash commands, and production tool scenarios.

What is the token limit for skills created with this tool?

The Skill Builder aims for a 'ruthless simplicity' approach, validating that the core skill remains under a 5,000-token budget for optimal performance.
