Structured dialogue tool for collaboratively designing features, APIs, and architecture through phased information gathering and validation.

• Guides through six phases: context discovery, requirements gathering, approach exploration, design presentation, documentation, and execution handoff
• Uses batched multi-question prompts to efficiently collect requirements across core goals, technical layers, quality attributes, integrations, and dependencies
• Generates 2-3 design approach options with pros/cons, then validates user preference before proceeding to detailed design sections
• Produces design documents and implementation task checklists with priority, phase, time estimates, and file references for immediate handoff to execution
