Creating a Claude Code skill involves a 4-phase process: Discovery, Frontmatter generation, Instruction Writing, and Validation. This structured workflow guides you from initial concept to a fully validated and optimized skill architecture.

Best practices for writing Claude skill instructions involve ensuring instruction clarity, optimizing descriptions, and adhering to strict naming conventions and length limits. Following a structured validation process guarantees your skill architecture meets these standards.

A SKILL.md file structure consists of YAML frontmatter defining the skill's metadata, followed by detailed instructions for execution. Proper structure ensures Claude Code can correctly parse and execute the skill according to best practices.

Claude Code skill development supports iterative workflows via its 4-phase process. You can iteratively refine use cases, YAML frontmatter, and instructions during the Discovery, Frontmatter, Instruction Writing, and Validation phases until fully validated.

YAML frontmatter is needed in Claude Code skills to define essential metadata like naming conventions and description limits. The validation phase checks this frontmatter to ensure your skill architecture adheres to optimized best practices.

You validate a Claude Code skill by performing validation checks in the final phase of the 4-step creation process. This ensures your SKILL.md file meets description length limits, naming conventions, and instruction clarity best practices before deployment.
