How can I prevent a skill from nagging me in every turn?

This skill utilizes session tracking via state files in .claude/hooks/state/ to ensure that once a reminder is acknowledged, it won't repeat within the same session.

Where are skill configurations stored?

All skill definitions and trigger logic are managed within the .claude/skills/skill-rules.json file in your project directory.

How do I trigger a skill based on user intent?

You can define intent patterns using regex in your skill-rules.json file, allowing Claude to detect implicit actions like 'add a feature' or 'refactor' without needing specific keywords.

What is the difference between Block and Suggest enforcement?

Block enforcement (Guardrail) stops a tool from running until requirements are met, while Suggest enforcement (Domain) provides helpful context to Claude before it processes a user prompt.

What is the 500-line rule in Claude Code skills?

The 500-line rule is a performance best practice that keeps the main SKILL.md file concise to maintain AI focus, using external reference files for more granular technical details.

개발자 도구

Streamlines the creation and management of Claude Code skills by enforcing Anthropic's architectural patterns and trigger best practices.

The Claude Skill Developer is a meta-utility designed to help engineers build, debug, and optimize custom extensions for the Claude Code CLI. It provides a standardized framework for implementing a two-hook architecture, ensuring skills remain performant by adhering to the 500-line rule and progressive disclosure patterns. By guiding users through the configuration of skill-rules.json and the implementation of multi-level enforcement—from gentle suggestions to critical guardrail blocks—it enables the creation of robust, domain-specific AI agents that activate exactly when needed.
