# North Star Metric

## 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. State the core user value delivered repeatedly.
2. Propose a primary metric that reflects that value.
3. List supporting input metrics and guardrails.
4. Note limits or failure modes of the metric.

## Output
- Core user value
- North Star Metric
- Supporting metrics
- Guardrails
