Turn ideas into fully formed designs and specs through natural collaborative dialogue. Use when planning new features, designing architecture, or making significant changes to the codebase.

Feature Design Assistant Help turn ideas into fully formed designs and specs through structured information gathering and collaborative validation. Announce at start: "I'm using the feature design assistant skill to design this feature." Phase 1: Context Discovery First, explore the codebase to understand: Project structure and tech stack Existing patterns and conventions Related features or modules Recent changes in relevant areas Phase 2: Structured Information Gathering Use AskUserQuestion to batch collect information efficiently. Each call can ask up to 4 questions. Round 1: Core Requirements (4 questions) Round 2: Technical Requirements (4 questions) Round 3: Integration & Dependencies (4 questions) Round 4: Clarifying Questions (Context Dependent) Based on previous answers, ask follow up questions. Examples: If UI layer selected: If High Security selected: Phase 3: Approach Exploration After gathering requirements, propose 2 3 approaches: Use AskUserQuestion to confirm approach: Phase 4: Design Presentation Present design in sections (300 500 words each), validate after each: 1. Architecture Overview High level structure 2. Data Model Entities, relationships, schema 3. API Design Endpoints, request/response 4. Component Design Internal modules, interfaces 5. Error Handling Error cases, recovery strategies 6. Testing Strategy What and how to test After each section, use AskUserQuestion: Phase 5: Documentation & Tasks Save Design Document Write to docs/designs/YYYY MM DD <topic design.md : Generate Implementation Tasks Phase 6: Execution Handoff Key Principles Batch questions efficiently Use all 4 question slots when appropriate Use multiSelect for non exclusive options Layers, features, requirements Use single select for decisions Approach, timeline, strategy Mark recommendations Add "(Recommended)" to preferred options Progressive refinement General → Specific questions Validate incrementally Check understanding at each phase YAGNI ruthlessly Remove unnecessary features from designs
