Structure a SKILL.md file by starting with YAML frontmatter containing the skill name and description, followed by a concise instruction body. Keep operational instructions brief and use progressive disclosure to delegate complex workflows to separate resource files.

Progressive disclosure in skill design is the practice of keeping the main instruction body lean by moving detailed logic into modular resources. This approach ensures the SKILL.md loads efficiently at runtime by separating scripts, references, and output assets into distinct files.

Use scripts for executable actions, references for static informational context, and assets for generated output files when packaging a Claude skill. Organizing resources into these distinct categories maintains a lean SKILL.md and ensures efficient runtime loading.

Package a Claude skill for distribution by validating that the SKILL.md has correct frontmatter and a concise workflow body, then organizing all modular resources like scripts and references into a compliant directory structure ready for runtime loading.

Yes, you need YAML frontmatter to create a Claude skill. Skill structure rules require compliant frontmatter containing both the skill name and description fields before the instruction body to ensure proper runtime loading and metadata parsing.

Keeping all instructions directly in SKILL.md creates runtime loading inefficiencies and bloats the file. Skipping progressive disclosure patterns prevents modular organization of scripts and references, making the skill harder to iterate and validate for distribution.
