Project instructions and knowledge covering architecture, conventions, dependencies, and operational constraints.
When to use it
You work on one service regularly and re-explain its shape every time.
What to prepare
The goal, relevant source material, constraints, examples, and the decision or action this should support.
How to get a strong result

How to use this prompt
Replace each placeholder with accurate context. Paste the complete prompt into Claude, review the response critically, resolve important questions, and use it as a considered input to the next decision—not as an unchecked final answer.
