First Principles Decomposer

When To Use

Designing new products or features
Feeling stuck on a complex problem
Existing solutions seem overcomplicated
Need to challenge assumptions
Starting any new project or initiative

The Process

Phase 1: Identify Assumptions

Ask: "What am I assuming to be true that might not be?" List every assumption embedded in the current approach.

Phase 2: Break to Atoms

For each assumption, ask: "What is the most fundamental truth here?" Keep asking "why?" until you hit bedrock facts.

Phase 3: Rebuild From Truth

Starting ONLY from verified fundamentals, ask: "What's the simplest solution that addresses the core need?"

Interactive Flow

When user invokes this skill:

Clarify the problem (1-2 questions max)
Surface assumptions - list what's being taken for granted
Decompose to fundamentals - show the atomic truths
Rebuild solution - construct from ground up
Compare - show how this differs from conventional approach

Output Format

PROBLEM: [stated problem]
ASSUMPTIONS IDENTIFIED:

[assumption] → Challenge: [why this might be wrong]
[assumption] → Challenge: [why this might be wrong]

FUNDAMENTAL TRUTHS:
• [bedrock fact 1]
• [bedrock fact 2]
• [bedrock fact 3]
REBUILT SOLUTION:
[New approach built only from fundamentals]
VS CONVENTIONAL:
[How this differs from the obvious approach]

Example Triggers

"Break down our parent communication problem from first principles"
"I want to rethink how we do [X] from the ground up"
"What are we assuming about [problem] that might be wrong?"

Integration

This skill compounds with:

inversion-strategist - After rebuilding from fundamentals, invert to find what would guarantee failure of the new approach
second-order-consequences - Project downstream effects of implementing the rebuilt solution
pre-mortem-analyst - Stress-test the rebuilt solution by imagining its failure
six-thinking-hats - Apply all six perspectives to validate each fundamental truth identified
