1. The Karpathy Decomposition Prompt — make Claude think before answering
Use when you're facing a complex idea, product, or technical problem.
Prompt:
"Approach this like a systems thinker.
1. Define the core problem clearly
2. Identify assumptions
3. List constraints and unknowns
4. Break into sub-problems
5. Propose 3 different approaches
6. Compare tradeoffs
7. Choose best approach
8. Give step-by-step execution
9. Highlight failure points
10. Suggest improvements after v1
Problem: [paste]"
This forces structured reasoning instead of shallow answers.

2. First Principles Builder — deep understanding instead of summaries
Prompt:
"Explain this from first principles.
Start with the most fundamental concepts.
Build upward layer by layer.
Avoid analogies initially.
Define terminology clearly.
Show how each layer connects.
Then provide mental model.
Then show real-world application.
Then give common misconceptions.
Then summarize in 5 bullet points.

4. Build Architecture Prompt — from idea to execution
Prompt:
"I want to build this. Design the implementation.
Give:
• simplest possible version
• architecture diagram (text)
• components
• data flow
• tech stack
• step-by-step build order
• edge cases
• scaling strategy
• possible bottlenecks
• v2 improvements
Idea: [insert]"
This removes guessing during building.
