# Requirements Definition

## When to use
- Use when the task clearly matches this PM activity.
- Use when a structured answer is more useful than a generic brainstorm.
- Use when the user needs explicit trade-offs, implications, or next steps.

## Instructions
1. Clarify the goal, user, or decision context.
2. Use the skill-specific lens below to structure the work.
3. Make assumptions explicit instead of hiding them.
4. End with a practical recommendation or next step.

### Skill-specific lens
1. Start from user outcome and system behavior.
2. Separate must-haves from nice-to-haves.
3. Cover constraints, edge cases, and quality attributes.
4. Note assumptions and unresolved decisions.

## Output
- Functional requirements
- Non-functional requirements
- Constraints
- Open questions
