Structured design dialogue that validates ideas before implementation begins.

• Enforces a hard gate: no code, scaffolding, or implementation actions until design is presented and approved
• Guides through nine sequential steps: context exploration, clarifying questions, approach proposals, design presentation, spec documentation, review loop, and user sign-off
• Applies to all projects regardless of perceived complexity; even simple tasks require a brief design review to catch unexamined assumptions
• Includes optional visual companion for mockups, diagrams, and layout comparisons during brainstorming
• Terminates by invoking the writing-plans skill to create implementation roadmaps
