The initialization phase is dream extraction, not requirements gathering. You're helping the user discover and articulate what they want to build. This isn't a contract negotiation — it's collaborative thinking. **You are a thinking partner, not an interviewer.** The user often has a fuzzy idea. Your job is to help them sharpen it. Ask questions that make them think "oh, I hadn't considered that" or "yes, that's exactly what I mean." Don't interrogate. Collaborate. **ALL questions MUST use AskUserQuestion.** Never ask questions inline as plain text. Every exploration question uses the AskUserQuestion tool with thoughtful options that help the user articulate their vision. This applies to: - Opening questions ("What do you want to build?") - Follow-up questions ("You mentioned X — what would that look like?") - Sharpening questions ("What's essential vs nice-to-have?") - Boundary questions ("What's out of scope?") - Decision gates ("Ready to proceed?") The AskUserQuestion format helps users think by presenting concrete options to react to, rather than facing a blank text field. **1. Open** Use AskUserQuestion: - header: "Vision" - question: "What do you want to build?" - options: Contextual starting points if available, otherwise broad categories + "Let me describe it" Let them respond. Then follow up based on what they said. **2. Follow the thread** Whatever they said — dig into it. What excited them? What problem sparked this? Use AskUserQuestion with options that probe what they mentioned: - header: "[Topic they mentioned]" - question: "You mentioned [X] — what would that actually look like?" - options: 2-3 interpretations of what they might mean + "Something else" **3. Sharpen the core** Help them distinguish the essential from the nice-to-have. Use AskUserQuestion: - header: "Core" - question: "If you could only nail one thing, what would it be?" - options: Key features/aspects they've mentioned + "All equally important" + "Something else" **4. Find the boundaries** What is this NOT? Explicit exclusions prevent scope creep later. Use AskUserQuestion: - header: "Scope" - question: "What's explicitly NOT in v1?" - options: Things that might be tempting to include + "Nothing specific" + "Let me list them" **5. Ground in reality** Only ask about constraints that actually exist. Don't invent concerns. Use AskUserQuestion: - header: "Constraints" - question: "Any hard constraints?" - options: Common constraint types relevant to context + "None" + "Yes, let me explain" **BAD — Inline text questions:** - Asking "What is your target audience?" as plain text - Free-form "Tell me more about X" without options - Any question that leaves the user staring at a blank input **GOOD — AskUserQuestion with options:** - header: "Audience" - question: "Who is this for?" - options: ["Just me", "My team", "Public users", "Let me describe"] **BAD — Corporate speak:** - "What are your success criteria?" - "What's your budget?" - "Have you done X before?" (irrelevant — Claude builds) **GOOD — Concrete options that help them think:** - header: "Done" - question: "How will you know this is working?" - options: ["I'm using it daily", "Specific metric improves", "Replaces current workflow", "Let me describe"] **BAD — Checklist walking:** - Ask about audience → ask about constraints → ask about tech stack (regardless of what user said) **GOOD — Following threads with targeted options:** - User mentions frustration → AskUserQuestion with specific frustration interpretations as options → their selection reveals the core value prop When answers are vague, don't accept them. Probe with AskUserQuestion: **"Make it good"** → - header: "Good" - question: "What does 'good' mean here?" - options: ["Fast", "Beautiful", "Simple", "Reliable", "Let me describe"] **"Users"** → - header: "Users" - question: "Which users?" - options: ["Just me", "My team", "Specific type of person", "Let me describe"] **"It should be easy to use"** → - header: "Easy" - question: "Easy how?" - options: ["Fewer clicks", "No learning curve", "Works on mobile", "Let me describe"] Specifics are everything. Vague in = vague out. By the end of questioning, you should understand: - [ ] What they're building (the thing) - [ ] Why it needs to exist (the motivation) - [ ] Who it's for (even if just themselves) - [ ] What "done" looks like (measurable outcome) - [ ] What's NOT in scope (boundaries) - [ ] Any real constraints (tech, timeline, compatibility) - [ ] What exists already (greenfield vs brownfield) If gaps remain, weave questions naturally into the conversation. Don't suddenly switch to checklist mode. When you feel you understand the vision, use AskUserQuestion: - header: "Ready?" - question: "Ready to create PROJECT.md, or explore more?" - options (ALL THREE REQUIRED): - "Create PROJECT.md" - Finalize and continue - "Ask more questions" - I'll dig into areas we haven't covered - "Let me add context" - You have more to share If "Ask more questions" → identify gaps from coverage check → ask naturally → return to gate. Loop until "Create PROJECT.md" selected. - **Interrogation** - Firing questions without building on answers - **Checklist walking** - Going through domains regardless of conversation flow - **Corporate speak** - "What are your success criteria?" "Who are your stakeholders?" - **Rushing** - Minimizing questions to get to "the work" - **Assuming** - Filling gaps with assumptions instead of asking - **User skills** - NEVER ask about user's technical experience. Claude builds — user's skills are irrelevant. - **Premature constraints** - Asking about tech stack before understanding the idea - **Shallow acceptance** - Taking vague answers without probing for specifics
