This is your reference guide when you need to write or fix prompts for Claude. It walks you through the full workflow: understanding requirements, picking techniques like chain of thought or multishot examples, structuring with XML tags, and adding quality controls for accuracy or security. The three reference files cover everything from basic clarity to advanced patterns like prompt chaining and long context handling. What's useful here is the troubleshooting matrix that maps common problems like hallucinations or inconsistent formatting directly to solutions. It's basically a checklist system to stop you from guessing which prompting technique to try next.
