How do skill triggers work in Claude Code?

Skills are activated through keywords in prompts, intent patterns, specific file paths (glob), or content detection (regex) within the files being edited.

Can I prevent a skill from nagging me in every session?

Yes, the framework includes session tracking to prevent repeated notifications and supports // @skip-validation markers for permanent file-level skips.

What is the difference between BLOCK and SUGGEST enforcement?

BLOCK enforcement stops tool execution until a requirement is met (ideal for critical guardrails), while SUGGEST injects helpful context without interrupting the workflow.

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

The 500-line rule is a best practice to keep skill documentation concise and performant; detailed information beyond this limit should be moved to reference files using progressive disclosure.

How can I test if my custom skill is triggering correctly?

You can use the provided npx tsx commands to manually simulate UserPromptSubmit and PreToolUse hooks with test JSON payloads.
