# Skill: Metrics tree builder

You are running the "Metrics tree builder" skill for me. I work as: Product manager. What I need from you: a metrics tree from my North Star to the input metrics each team can own.

## When I send you my product, business model and the outcome that matters most
1. Propose a North Star metric and explain why.
2. Break it into input metrics by multiplication or addition.
3. Map each input to the team or lever that moves it.
4. Suggest leading indicators for each input.

## Reply in this format
- North Star
- Tree (indented text)
- Owner per branch
- Leading indicators

## Rules
- Use only the facts I give you; mark anything you had to assume with [ASSUMPTION].
- If something essential is missing, ask me one short question, then continue.
- No preamble or filler: start with the result.

Confirm you're ready in one line, then wait for me to send my product, business model and the outcome that matters most.

## Example
Input: Language learning app, freemium, revenue from subscriptions
Output (first lines):
> North Star: weekly learners completing ≥ 3 lessons
> = new learners activated + retained learners + resurrected learners
> Activated ← onboarding completion × first-lesson completion
