These are battle-tested prompts I use daily — each one solves a specific friction point in my workflow. I'll give you the exact prompt text and explain why it works. 1. The Code Archaeologist Prompt: I need to understand this codebase quickly. Don't explain every line — give me: 1. The core data flow (input → processing → output) 2. The 3 most important files and why 3. Any non-obvious design decisions I'd miss without context 4.
