Use when a user wants to plan and implement a new feature or bug fix from scratch. Triggers on requests like "I want to build X", "add a feature for Y", "fix Z", or when the user invokes /plan-and-build. Guides through clarifying questions, breaks work into small features, sets up a tasks folder, implements each feature with TDD (test first), and produces a manual testing guide when complete.
