Claude Skill Writing & TDD Framework FAQs

Question 1

What is a Claude Code Skill?

Accepted Answer

A skill is a specialized, reusable reference guide containing techniques, patterns, or tools that enhance Claude's behavior and decision-making across different projects.

Question 2

When should I create a new skill vs. project documentation?

Accepted Answer

Create a skill when a technique applies broadly across multiple projects; use project documentation (like CLAUDE.md) for conventions specific to a single codebase.

Question 3

How does this help with context limits?

Accepted Answer

The framework provides specific guidelines for token efficiency, such as keeping core SKILL.md files under 500 words and using progressive disclosure for heavy references.

Question 4

What is Claude Search Optimization (CSO)?

Accepted Answer

CSO is the practice of writing metadata and descriptions in a way that allows Claude to accurately identify, search for, and load the most relevant skill for any given task.

Question 5

Why use TDD for writing skills?

Accepted Answer

Test-Driven Development ensures a skill is actually effective by forcing you to watch an agent fail a task (the Red phase) without the skill before documenting the solution.
