Test-driven development for skill documentation involves writing a failing RED scenario first, implementing the GREEN skill to pass it, then refining through REFACTOR cycles. This approach reduces ambiguity and ensures reusable, battle-tested skills.

The best way to structure skill frontmatter is using a frontmatter-driven skeleton that enforces validation constraints on triggers, patterns, and references. This ensures concise, indexed content optimized for fast Claude discovery and low-token loading.

Yes, you can apply RED-GREEN-REFACTOR cycles to process documentation by first drafting a failing scenario, implementing the skill to pass it, then refactoring. This workflow codifies a repeatable, test-driven approach to authoring reusable skills.

Test-driven skill writing works for scaling documentation across teams by enforcing frontmatter constraints, progressive disclosure, and risk mitigation. It facilitates rapid creation and verification cycles for maintainable skills that scale across teams and models.

Skill documentation loads with high token usage when it lacks concise, indexed content and lightweight references. Enforcing constraints on sections and frontmatter ensures low-token skills that load only when needed, optimizing discovery.

You should not use test-driven development for skill authoring when your documentation requires no repeatable structure or validation. This approach is designed for creating reusable, battle-tested skills needing frontmatter validation and progressive disclosure.
