Reproduce a bug from a report
Turn a vague report into a reliable reproduction by exploring the actual code paths.
What this prompt helps you do
A minimal reproduction with the conditions required, the code path taken, and the point of divergence.
When to use it
A bug is reported and cannot be reproduced from the description alone.
What to prepare
The goal, relevant source material, constraints, examples, and the decision or action this should support.
How to get a strong result
Establish the reproduction before proposing a cause; a fix for an unreproduced bug cannot be verified.
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.
