  Technical           Value               Behavior
  Readiness         Realization          Established

Application Steps:

1. Map current user journey
2. Identify where users drop off
3. Define clear metrics for each moment
4. Optimize time between moments

Model 15: Hook Model (Nir Eyal)

Framework:

        ┌─────────────────┐
        │    TRIGGER      │
        │ (External/      │
        │  Internal)      │

        │  behavior)      │
        └────────┬────────┘
                 │
                 ▼
        ┌─────────────────┐
        │    REWARD       │
        │ (Variable       │
        │  satisfaction)  │
        └────────┬────────┘
                 │
                 ▼
        ┌─────────────────┐
        │   INVESTMENT    │
        │ (Stored value,  │
        │  loading        │
        │  next trigger)  │
        └────────┬────────┘
                 │
                 └───────────▶ [Back to Trigger]

Application Steps:

1. Identify internal triggers (emotions: bored, anxious, curious)
2. Design simple action with minimal friction
3. Create variable rewards (tribe, hunt, self)
4. Build investment that improves next cycle

Model 22: Value Metric Framework

When to use: Aligning pricing with delivered value

Criteria for good value metrics:

1. Easy to understand: Customer gets it immediately
2. Aligns with value: More usage = more value
3. Grows with customer: Scales as customer succeeds
4. Predictable: Customer can estimate cost

Common value metrics by category:

Model 36: Four Fits (Brian Balfour)

When to use: Assessing PLG readiness

Framework:

┌────────────────────────────────────────────────────┐

Execution Flow

Step 1: Understand the Challenge

rag.query({
  query: input.challenge,
  filter: { type: "plg_challenge" },
  topK: 5
})

Step 2: Match to Models

Based on challenge keywords and context, identify:

• Primary model (1-2)
• Supporting models (2-3)
• Related case studies

Step 3: Provide Framework Application

ui_kit.panel({
  type: "mental_model",
  title: selectedModel.name,
  content: {
    overview: modelOverview,
    framework: frameworkSteps,
    applicationGuide: howToApply,
    examples: relevantExamples
  }

Guardrails

• Only use whitelisted tools from skill configuration
• Match models to actual challenge, not forced fits
• Provide concrete application steps, not just theory
• Include relevant examples when available
• Suggest model combinations for complex challenges
• Update model recommendations based on feedback
• Don't overwhelm with too many models at once
• Prioritize actionable frameworks over academic ones
