What is the difference between BLOCK and SUGGEST enforcement?

BLOCK is a critical guardrail that prevents tool execution until a skill is used, whereas SUGGEST provides advisory guidance without interrupting the developer's workflow.

What is the 500-line rule for Claude Skills?

The 500-line rule is a performance best practice that mandates keeping SKILL.md files under 500 lines. Detailed documentation should be moved to reference files to ensure the AI processes context efficiently.

How do I trigger a custom skill in Claude Code?

Skills are activated via the skill-rules.json file using keywords, intent patterns (regex), specific file path globs, or content detection patterns found within the codebase.

How do I prevent Claude from repeatedly nagging me with the same skill?

The Skill Developer framework uses session tracking and state files to ensure that once a skill has been acknowledged or used in a session, it won't trigger repeated blockages.
