The question and its context
A prototype rarely tells the whole story. What context helps another engineer give useful feedback? Share an approach that explains what changed, what you learned and where you need a second perspective.
An illustrative perspective
One useful structure is: the question we tested, the evidence we collected, and what we want to try next. A failed experiment can be a useful update too.
Keep the exchange useful
Describe what you have observed, explain your reasoning and make room for another approach. Keep credentials and confidential information out of the conversation.
