What is the EARS format used in this skill?

EARS stands for Easy Approach to Requirements Syntax. It uses specific patterns like 'WHEN [event] THEN [system] SHALL [response]' to create unambiguous, testable requirements.

Can I use this for simple bug fixes?

While you can, it is less suitable for simple fixes with obvious solutions. This methodology is designed for complex features where the cost of rework is high.

How does this improve AI-assisted development?

By breaking work into phases, it provides the AI with clear context and smaller, manageable objectives, which significantly reduces errors and improves output quality.

Which IDEs are compatible with this skill?

This methodology is compatible with Claude Code, Cursor, VS Code, and Windsurf, making it versatile for various modern development environments.
