Skill Developer

About

This skill provides a comprehensive framework for building and maintaining custom capabilities within Claude Code, ensuring that domain-specific guidance and guardrails are applied consistently. It guides developers through implementing two-hook architectures—UserPromptSubmit for proactive suggestions and PreToolUse for enforcement—while managing complex trigger patterns like keywords, intent, and file paths. By enforcing standards such as the 500-line rule and progressive disclosure, it helps maintain high-quality documentation and automated workflows that improve code safety and developer productivity without introducing unnecessary friction.

Key Features

• Session tracking and skip conditions to prevent repetitive notifications during active development
• Implementation guidance for two-hook architectures including proactive suggestions and error reminders
• 8 GitHub stars
• Management of enforcement levels to block critical errors or suggest domain best practices
• Standardization of skill structures using the 500-line rule and progressive disclosure patterns
• Configuration of skill triggers using keywords, intent patterns, and glob-based file paths

Use Cases

• Creating domain-specific architectural guides that activate automatically based on file context
• Designing custom guardrails to prevent common database errors or security vulnerabilities
• Debugging and testing skill activation logic using manual CLI commands and JSON mocks
