Skill Development Guide FAQs

Question 1

When should I use the 'references/' directory?

Accepted Answer

Use the references directory for large documentation, schemas, or API specs that Claude should search or consult as needed, rather than loading them into every prompt.

Question 2

How do I improve how often my skill is triggered?

Accepted Answer

Triggering is determined by the name and description in the SKILL.md YAML frontmatter. Use specific third-person trigger phrases that describe exactly when the skill should be used.

Question 3

How long should the main SKILL.md file be?

Accepted Answer

Ideally, the body should be between 1,500 and 2,000 words. Detailed patterns and long-form content should be moved to reference files to maintain performance.

Question 4

What is the 'progressive disclosure' principle in skill design?

Accepted Answer

It is a three-level loading system (Metadata, SKILL.md, and Resources) designed to keep the context window lean by only loading detailed information when Claude specifically needs it.

Question 5

What is a Claude Code Skill?

Accepted Answer

A skill is a modular, self-contained package that extends Claude's capabilities with specialized knowledge, workflows, and tools, transforming it into a domain-specific agent.
