What is the 500-line rule?

The 500-line rule is a best practice recommending that SKILL.md files remain under 500 lines to maintain Claude's context window efficiency and overall performance.

How do I test my skill triggers manually?

You can use npx tsx commands to simulate UserPromptSubmit or PreToolUse events with specific JSON payloads to verify your regex and glob activation logic.

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 performance in specific coding tasks.

Can I disable specific skills during a session?

Yes, you can use environment variables like SKIP_SKILL_GUARDRAILS for emergency disables or add // @skip-validation markers to specific files to bypass checks.

How do Guardrail Skills differ from Domain Skills?

Guardrail skills use 'block' enforcement to prevent critical errors and data loss, while Domain skills use 'suggest' to provide advisory architectural and best-practice guidance.
