Test-driven development for Skills means writing pressure-test scenarios first, watching them fail, then drafting and refactoring your Skill until it passes. This RED-GREEN-REFACTOR cycle ensures your documentation is accurate, reliable, and meets search optimization standards before deployment.

Skill documentation requires concise frontmatter, a structured SKILL.md file with progressive disclosure, clear naming, and descriptions optimized for Claude search. The file should keep heavy sections organized so content loads only when needed, staying under practical length limits.

Yes. You can run pressure scenarios with subagents across Claude Code and Codex to validate your Skill before deployment. This cross-environment testing ensures your Skill performs reliably in the contexts where users will run it.

Use test-driven development with pressure scenarios to verify that your Skill meets concise frontmatter requirements, structured documentation standards, and search optimization best practices. Iterate through RED-GREEN-REFACTOR cycles until your Skill passes all validation gates.

Apply progressive disclosure to organize content hierarchically—keep SKILL.md token-efficient by loading heavy sections only when needed. Use cross-references, concise descriptions, and enforce naming and description governance so documentation stays clear and maintainable.
