# The Feedback Loop

## When This Skill Activates

Claude uses this skill when:
- Building feedback collection
- Measuring product-market fit
- Implementing user research
- Creating feedback systems

## Core Frameworks

### 1. Superhuman PMF Survey

**The Question:**
> "How would you feel if you could no longer use [product]?"
> - Very disappointed
> - Somewhat disappointed
> - Not disappointed

**PMF Threshold:**
- >40% "very disappointed" = strong PMF
- <40% = need to improve

### 2. Talk to Users (YC)

**The Approach:**
- Talk to users weekly (minimum)
- Ask open-ended questions
- Watch them use product
- Focus on jobs-to-be-done
