I have had a user story and a research plan and only realized deep in the implementation that a fundamental detail about how the code works was missing (specifically, that types and sdks are generated from OpenAPI spec) - this missing meant the plan was wrong (didn’t read carefully enough) and the implementation was a mess
Yeah I agree. There's a lot more needed than just the User Story, one way I'm thinking about it is that the "core" is deliverable business value, and the "shells" are context required for fine-grained details. There will likely need to be a step to verify against the acceptance criteria.
I hope to back up this hypothesis with actual data and experiments!
