Set up a product Project with durable context
Give Claude the strategy, constraints, and vocabulary once so every later conversation inherits them.
What this prompt helps you do
Project instructions and a knowledge set covering strategy, users, constraints, metrics, and house decisions.
When to use it
You keep re-explaining the same product background at the start of every conversation.
What to prepare
The goal, relevant source material, constraints, examples, and the decision or action this should support.
How to get a strong result
Write the constraints and non-goals explicitly; those are what Claude cannot infer and what keeps answers grounded.
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.
