How do skill triggers work in Claude Code?

Skills are activated via defined triggers in skill-rules.json, including keyword matching, intent regex patterns, file path globs, or specific file content detection.

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

It is an Anthropic best practice suggesting that SKILL.md files stay under 500 lines to maintain AI performance and focus, utilizing reference files for deeper technical details.

What is the difference between BLOCK and SUGGEST enforcement?

BLOCK physically prevents tool execution until specific criteria are met (ideal for critical security), while SUGGEST injects advisory context before the prompt without stopping the workflow.

Can I temporarily disable skill guardrails?

Yes, you can bypass validation by adding the // @skip-validation marker to files or by setting the SKIP_SKILL_GUARDRAILS environment variable to true.

Acerca de

The Skill Developer skill is a meta-utility designed to help engineers build, debug, and maintain specialized capabilities within Claude Code. It provides a standardized framework for implementing domain-specific guidance, guardrails, and automated workflows. By mastering the two-hook architecture—UserPromptSubmit for proactive suggestions and post-response hooks for gentle reminders—developers can ensure Claude adheres to project-specific patterns, security protocols, and architectural best practices without creating unnecessary friction in the development cycle.
