Apply first-principles thinking to break down complex problems into fundamental truths and rebuild solutions from the ground up. Use when solving strategic decisions, breaking through blockers, or challenging assumptions. Triggers on first principles, Elon Musk methodology, fundamental truths, strip assumptions, physics of the problem, rebuild from scratch.

# First-Principles Thinking

Apply systematic first-principles analysis to break down complex problems into fundamental truths and rebuild solutions from the ground up.

## When to Apply This Framework

Use first-principles thinking when you encounter:
- Complex decisions with no clear answer
- Conventional approaches that aren't working
- Assumptions that may be limiting solutions
- Need to innovate beyond industry norms
- Problems that feel "impossible"

## The 15 First-Principles Prompts

### Category 1: Foundation (Strip to Fundamentals)

**1. "What are the physics of this problem?"**
Strip everything to objective reality. Remove opinions, preferences, and history.
> *Apply when:* You need to understand what's actually true vs what you believe is true.

**2. "If I couldn't rely on existing assumptions, how would I solve this?"**
Assumptions are invisible cages. This prompt forces fresh thinking.
> *Apply when:* You're stuck in conventional approaches or "the way things are done."

**3. "What are the problem's fundamental components?"**
Break problems into atoms. What are the irreducible elements?
> *Apply when:* A problem feels overwhelming or too complex to tackle.

### Category 2: Ideal State (Unconstrained Vision)

**4. "What would the optimal solution look like if cost didn't exist?"**
Constraints ruin creativity too early. First imagine the ideal, then work backward.
> *Apply when:* Budget or resources are limiting your thinking prematurely.

**5. "If I were forced to cut 90 percent of this, what would remain?"**
Brutal prioritization. What is truly essential?
> *Apply when:* You have too many options, features, or tasks competing for attention.

### Category 3: Risk Analysis (Failure Modes)

**6. "If this failed completely, what would be the root cause?"**
Start with failure to engineer success. Pre-mortem thinking.
> *Apply when:* Planning a launch, making a major commitment, or assessing risk.

**7. "What would a solution look like if I ignored industry
