What is progressive disclosure in this context?

Progressive disclosure is the strategy of keeping the primary SKILL.md concise while using reference files for detailed information, preventing context bloat.

How does the 'BLOCK' enforcement level work?

The BLOCK level physically prevents Claude from executing tools like Edit or Write until the specific skill requirements or safety verifications are satisfied.

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

The 500-line rule is a best practice to keep SKILL.md files under 500 lines to preserve context window space and ensure Claude remains performant and focused.

Where are skill configurations stored?

All skill definitions, trigger conditions, and enforcement settings are managed within the .claude/skills/skill-rules.json configuration file.

How can I test my new skill triggers?

You can test triggers manually by piping JSON payloads into the hook scripts using npx tsx to simulate user prompts or tool execution events.

Developer Tools

Standardizes the creation and management of specialized Claude Code skills following Anthropic's official architectural patterns and best practices.

About

This skill provides a comprehensive framework for building domain-specific capabilities within Claude Code. It guides developers through the entire lifecycle of skill creation, from defining YAML frontmatter and configuring skill-rules.json to implementing advanced trigger patterns like regex-based intent detection and file-path globs. By enforcing best practices such as the 500-line rule and progressive disclosure, it ensures that custom skills remain performant, maintainable, and contextually relevant without overwhelming the model's token limit. It is an essential tool for teams looking to codify their internal standards and automate high-quality code generation.

Key Features

Management of two-hook architecture including UserPromptSubmit and PreToolUse
Automated skill structure generation with YAML frontmatter
Guidance on Anthropic's 500-line rule and progressive disclosure patterns
Advanced trigger configuration using keywords, intent patterns, and file paths
0 GitHub stars
Implementation of enforcement levels including block, suggest, and warn

Use Cases

Designing custom guardrails to prevent common codebase-specific errors
Debugging and optimizing skill activation triggers to reduce false positives
Developing domain-specific guidance for niche frameworks or internal libraries
