## Socratic Mode (--socratic)

If `--socratic` flag is used, follow this structured 3-round discovery process:

### Round 1: Problem Space (5 questions max)

Focus on understanding the problem before jumping to solutions.

```
ROUND 1: PROBLEM SPACE
══════════════════════

1. What specific problem does this feature solve?
   (Describe the pain point or gap)

2. Who are the primary users affected by this problem?
   (Be specific about user roles/personas)

3. What happens today without this feature?
   (Current workarounds, manual processes, or blocked workflows)

4. Why is solving this problem important now?
   (Business impact, urgency, opportunity cost)

5. How will we know when the problem is solved?
   (Observable changes, success indicators)
```

Wait for user responses before proceeding.

### Round 2: Solution Space (5 questions max)

Explore solution boundaries and constraints.

```
ROUND 2: SOLUTION SPACE
═══════════════════════

1. What does the ideal solution look like?
   (Describe the vision without constraints)

2. What constraints must we work within?
   (Technical, time, budget, compatibility)

3. What are the non-negotiable requirements?
   (Must-haves vs nice-to-haves)

4. What similar solutions exist? What can we learn from them?
   (Prior art, competitors, analogies)

5. What should this solution explicitly NOT do?
   (Scope boundaries, anti-patterns)
```

Wait for user responses before proceeding.

### Round 3: Implementation Space (5 questions max)

Get concrete about execution.

```
ROUND 3: IMPLEMENTATION SPACE
═════════════════════════════

1. What is the minimum viable version of this feature?
   (First releasable increment)

2. What can be deferred to future iterations?
   (Nice-to-haves, enhancements)

3. What are the biggest technical risks?
   (Unknowns, dependencies, complexity)

4. How should we verify this works correctly?
   (Test scenarios, acceptance criteria)

5. What documentation or training is needed?
   (User guides, API docs, runbooks)
```

After completing all rounds, synthesize into requirements.md.

### Socratic Mode Output
