What is a Claude Code Skill?

A skill is a modular, self-contained package that extends Claude's capabilities with specialized knowledge, procedural workflows, and tool integrations.

How does progressive disclosure benefit Claude?

It optimizes the context window by only loading information when needed: starting with metadata, then the SKILL.md body, and finally external resources or scripts.

What are bundled resources in a skill?

Resources include executable scripts for deterministic tasks, reference files for deep domain knowledge, and assets like templates or icons used in output.

Why use TDD for skill creation?

Using TDD ensures the skill actually solves a problem. By watching an agent fail without the skill (Red) and pass with it (Green), you verify the skill's effectiveness.

What is the difference between a skill and a project convention?

Skills are reusable techniques or patterns that apply across multiple projects. Project-specific conventions should be placed in a CLAUDE.md file instead.

Learning & Documentation

Enables the creation of robust, bulletproof Claude Code skills using a specialized Test-Driven Development (TDD) approach to process documentation.

This skill provides a rigorous framework for extending Claude's capabilities through standardized skill creation. By applying the Red-Green-Refactor cycle to documentation, it ensures that new skills are not just passive instructions but verified solutions to specific agent failures. It guides users through pressure-testing agents with subagents, identifying rationalization loopholes, and structuring modular content using a progressive disclosure design to maintain high token efficiency and discoverability.
