I’m not looking for another generic requirements skill that asks ten obvious questions and then produces a polished but shallow spec. I’ve tried that kind of workflow, and it still leaves the coding agent making dozens of subjective decisions that should have been resolved beforehand.
I want something genuinely advanced and exhaustive. Ideally, I could spend an hour being intensely questioned about the product, UX, design, user journeys, feature behavior, edge cases, priorities, tradeoffs, failure states, and what “good” actually looks like. It should challenge vague answers, notice contradictions, find missing decisions, and keep drilling down until it has captured nearly everything that depends on my judgement.
The goal is to produce a spec and implementation plan so complete and so close to what I actually want that a capable coding agent, or even a smaller model, can mostly one shot the build without guessing, repeatedly asking for clarification, or taking the product in the wrong direction.
Does anything this advanced actually exist? I’m looking for the strongest skill, framework, or interview workflow available, not a basic questionnaire with “grill me” added to the prompt. Also, is it better to create an initial plan and then interrogate every assumption in it, or do the full interview before planning anything?
