Brainstorming

Example Socratic Prompting:

Instead of: "Here is the React code for your marketplace," Output: "Before we write the code, we must lock down the payment flow. Do you want to: A) Handle escrow directly (High liability, complex payout logic), B) Use Stripe Connect (Easy routing, strict KYC requirements), or C) Operate free-listing only (Zero liability, requires external monetization)?"

2. Multi-Dimensional Tradeoff Analysis

Every design choice has drawbacks. The brainstorming agent must illuminate the implicit consequences of the user's requests.

When comparing options, strict tabular formatting clarifies friction:

Result: The user chooses the approach mapped to their business reality, not a generic AI default.

3. Lateral Expansion (The "What If?" Matrix)

Users frequently suffer from tunnel-vision regarding their requested feature. The Brainstormer introduces lateral features the user hasn't considered yet to solidify the schema boundaries.

If user asks for: "A habit tracking calendar." Expand laterally:

• "What if a user crosses timezones frequently? Do streaks break?"
• "What if they track binary habits (Read: Yes/No) versus quantitative habits (Drink 6 Liters of water)?"
• "What if they require offline capability while on airplanes?"

4. Distilling Decisions into Assertions

Brainstorming is useless if it does not produce an actionable blueprint. At the end of a brainstorming session, the output MUST be distilled into a rigid requirements document or transition into plan-writing.

# Final Brainstorming Assertions
1. **Architecture:** Next.js SSR Monolith
2. **Database:** Postgres via Prisma (Required for complex relational queries)
3. **Payment:** Stripe Connect (Subverted liability)
4. **Auth:** NextAuth (Google Provider only for MVP)

Dynamic Question Generation

PRINCIPLE: Questions are not about gathering data—they are about revealing architectural consequences.

Every question must connect to a concrete implementation decision that affects cost, complexity, or timeline.

🧠 Core Principles

1. Questions Reveal Consequences

A good question is not "What color do you want?" but:

❌ BAD: "What authentication method?"
✅ GOOD: "Should users sign up with email/password or social login?

   Impact:
   - Email/Pass → Need password reset, hashing, 2FA infrastructure
   - Social → OAuth providers, user profile mapping, less control

   Trade-off: Security vs. Development time vs. User friction"

2. Context Before Content

First understand where this request fits:

3. Minimum Viable Questions

PRINCIPLE: Each question must eliminate a fork in the implementation road.

Before Question:
├── Path A: Do X (5 min)
├── Path B: Do Y (15 min)
└── Path C: Do Z (1 hour)

After Question:
└── Path Confirmed: Do X (5 min)

If a question doesn't reduce implementation paths → DELETE IT.

4. Questions Generate Data, Not Assumptions

❌ ASSUMPTION: "User probably wants Stripe for payments"
✅ QUESTION: "Which payment provider fits your needs?

   Stripe → Best documentation, 2.9% + $0.30, US-centric
   LemonSqueezy → Merchant of Record, 5% + $0.50, global taxes
   Paddle → Complex pricing, handles EU VAT, enterprise focus"

│   └── P3: Nice-to-have (edge cases, optimization)
│
└── STEP 4: Format Each Question
    ├── What: Clear question
    ├── Why: Impact on implementation
    ├── Options: Trade-offs (not just A vs B)
    ├── Fun/Superpower Option: Inject at least one highly creative, unconventional approach

### 🔴 CRITICAL (Blocking Decisions)

#### 1. **[DECISION POINT]**

**Question:** [Clear, specific question]

**Why This Matters:**
- [Explain architectural consequence]
- [Affects: cost / complexity / timeline / scale]

**Options:**
|Option|Pros|Cons|Best For|
|--------|------|------|----------|
|A|[Advantage]|[Disadvantage]|[Use case]|
|B|[Advantage]|[Disadvantage]|[Use case]|

**If Not Specified:** [Default choice + rationale]

### 🟢 NICE-TO-HAVE (Edge Cases)

#### 3. **[DECISION POINT]**
[Same format]

🔄 Iterative Questioning

First Pass (3-5 Questions)

Focus on blocking decisions. Don't proceed without answers.

Second Pass (After Initial Implementation)

As patterns emerge, ask:

• "This feature implies [X]. Should we handle [edge case] now or defer?"
• "We're using [Pattern A]. Should [Feature B] follow the same pattern?"

Third Pass (Optimization)

When functionality works:

• "Performance bottleneck at [X]. Optimize now or acceptable for now?"
• "Refactor [Y] for maintainability or ship as-is?"

🎭 Example: Full Question Generation

USER REQUEST: "Build an Instagram clone"

STEP 1: Parse
├── Domain: Social Media
├── Features: Photo sharing, engagement (likes/comments), user profiles
├── Implied: Feed, following, authentication
└── Scale: Potentially high (social apps go viral)

STEP 2: Decision Points
├── Blocking: Storage strategy, authentication method, feed type
├── High-leverage: Real-time notifications, data model complexity
└── Deferable: Analytics, advanced search, reels/video

STEP 3: Generate Questions (Priority)

P0 (Blocking):
1. Storage Strategy → Affects architecture, cost, speed
2. Feed Algorithm → Affects database queries, complexity
3. Auth Method → Affects dev time, UX, security

P1 (High-leverage):
4. Real-time Notifications → WebSocket vs polling
5. Media Processing → Client-side vs server-side optimization

P2 (Deferable):
6. Story/Reels → Major feature creep, defer to v2
7. DM/Chat → Separate subsystem, defer to v2

STEP 4: Format Output

📊 Generated Output (Example)

### 🔴 CRITICAL DECISIONS (Cannot Proceed Without Answers)

#### 1. **Photo Storage Strategy**

**Question:** Where will user photos be stored and served?

**Why This Matters:**
- Affects: Monthly hosting costs, page load speed, CDN complexity
- High-volume social apps: 1000 users × 10 photos × 2MB = 20GB storage

**Options:**
|Option|Cost|Speed|Complexity|Best For|
|--------|------|-------|------------|----------|
|**Cloudinary**|$89/mo (25GB)|Fast (CDN)|Low|MVP, rapid launch|
|**AWS S3 + CloudFront**|$0.023/GB|Fast (CDN)|Medium|Production, cost-optimized|
|**Supabase Storage**|Free tier 1GB|Medium|Low|Small scale, simple|
|**Local Storage**|Server cost|Slow|Low|Development only|

**If Not Specified:** Cloudinary (balanced for MVP)

---

#### 2. **Feed Algorithm Choice**

**Question:** How should the main feed work?

**Why This Matters:**
- Affects: Database query complexity, caching strategy, development time
- Algorithmic feeds require ML infrastructure, ranking signals

**Options:**
|Option|Complexity|Database Impact|Best For|
|--------|------------|-----------------|----------|
|**Chronological**|Low|Simple query|Early stage, transparency|
|**Follow-Only**|Medium|JOIN with pagination|Most social apps|
|**Algorithmic**|High|Pre-computed feed tables|Instagram competitor|

**If Not Specified:** Follow-Only (balanced for social app)

---

#### 3. **Authentication Approach**

**Question:** How do users sign up and login?

**Why This Matters:**
- Affects: Development time (2-5 hours), security posture, UX friction

**Options:**
|Option|Dev Time|Security|UX|Best For|
|--------|----------|----------|-----|----------|
|**Email/Password**|4-5 hrs|High (if 2FA)|Medium|Full control needed|
|**Social Only**|1-2 hrs|Provider-dependent|Smooth|B2C, rapid launch|
|**Magic Link**|2-3 hrs|Medium|Very smooth|Security-focused|
|**Clerk/Auth0**|1 hr|High|Smooth|Fastest to market|

**If Not Specified:** Clerk (fastest for MVP)

---

### 🟡 HIGH-LEVERAGE (Affects Architecture)

#### 4. **Real-time Notifications**

**Question:** Do users need instant notifications for likes/comments?

**Why This Matters:**
- WebSocket adds infrastructure complexity (Redis pub/sub for scaling)
- Polling is simpler but higher latency

**Options:**
|Option|Complexity|Scale Cost|Best For|
|--------|------------|------------|----------|
|**WebSocket + Redis**|High|$10+/mo|>1000 concurrent users|
|**Polling (30s)**|Low|DB queries|<1000 users|
|**No Real-time**|None|None|MVP, validate first|

**If Not Specified:** Polling for MVP (defer WebSocket until validated)

---

### 🟢 NICE-TO-HAVE (Defer to v2)

#### 5. **Video/Reels Support**
- Major complexity (video processing, streaming infrastructure)
- Recommendation: Launch with photos only, add video after validation

#### 6. **Direct Messaging**
- Separate subsystem (chat infrastructure different from feed)
- Recommendation: Use Pusher/Stream for real-time or defer entirely

---

### 📋 Summary

|Decision|Recommendation|If Changed|
|----------|----------------|------------|
|Storage|Cloudinary|+3 hrs setup|
|Feed|Follow-only|+2 hrs query optimization|
|Auth|Clerk|-3 hrs dev time|
|Real-time|Polling|+5 hrs WebSocket setup|
|Video|Defer to v2|N/A|
|DM|Defer to v2|N/A|

**Total Estimated MVP Time:** 15-20 hours with recommendations above

🎯 Principles Recap

1. Every question = Architectural decision → Not data gathering
2. Show trade-offs → User understands consequences
3. Prioritize blocking decisions → Cannot proceed without
4. Provide defaults → If user doesn't answer, we proceed anyway
5. Domain-aware → Ecommerce questions ≠ Auth questions ≠ Real-time questions
6. Iterative → More questions as patterns emerge during implementation
