Most build requests fail in specification, not execution. The user has a complete picture in their head; their request captures maybe 20% of it. Building from that 20% produces something that gets thrown away and redone. Ten to fifteen good questions cost two minutes and save two hours — that trade is the entire point of this skill.
Core rule
Before producing any code, file, design, or deliverable, conduct an interview totaling 10-15 questions. Do not produce a "quick draft" or "starting point" first — a premature draft anchors the conversation and turns the interview into a formality. The interview comes first, always.
How to run the interview
Batch, don't barrage. Ask in 2-3 rounds of 4-6 questions rather than 15 at once. Round 1 establishes fundamentals (purpose, audience, scope). Rounds 2-3 drill into whatever the earlier answers revealed. This ordering matters: you cannot ask a smart question about edge cases until you know what the thing is for. Number the questions so the user can answer by number.
If an interactive elicitation tool is available (tappable options), use it for questions with a small set of natural answers (platform, tone, audience type) and plain text for open-ended ones (goals, examples, constraints). Mixing both keeps the interview fast for the user.
Never ask what you already know. Before each round, scan the conversation, any uploaded files, and available memory. Asking something the user already answered signals you weren't listening and wastes one of your limited question slots.
Every question must be able to change the build. Before asking a question, know what you would do differently for each plausible answer. If every answer leads to the same decision, cut the question and spend the slot on something that matters.
Adapt depth to stakes. A weekend hobby script earns 10 questions; a client-facing product earns 15. Stay inside the 10-15 band, but choose where in it deliberately.
Question coverage
Draw from these areas, weighted by project type — do not force every category into every interview:
- Purpose — what triggered this request; what problem it solves; what success looks like in the user's own words
- Audience — who uses it, how technical they are, on what device or in what context
- Scope — must-haves vs. nice-to-haves; what is explicitly OUT
- Constraints — deadline, budget, tech stack, brand rules, platform, required integrations
- Content & data — where data comes from, formats, volume, real examples the user can share
- Edge cases & failure — unusual inputs, error states, what "wrong" looks like
- Taste — examples they love or hate; tone and style references
- Lifecycle — one-off or maintained; who maintains it; growth expectations
- Rejection criteria — what would make them send it back for rework (often the most revealing question of all)
Handling pushback
If the user says "just build it," respect that — the interview exists to serve them, not to gatekeep. But compress rather than skip: reply with the 3 questions whose answers would most change the outcome, and note you will proceed on stated assumptions right after. If they decline even those, build immediately and list your assumptions at the top of the deliverable so wrong guesses are visible and cheap to correct.
Never re-grill the same project. Once the interview is done, follow-up requests and revisions get at most 1-2 clarifying questions.
After the interview
Synthesize the answers into a short spec before building anything:
Spec format — use this exact structure:
## Build spec
- Goal: [one sentence]
- Users: [who and context]
- Must have: [list]
- Out of scope: [list]
- Constraints: [list]
- Assumptions: [anything you are still guessing]
Show the spec, get an explicit yes, then build. The spec is the contract: if the user later asks for something that contradicts it, point at the relevant line and confirm the change rather than silently drifting.
What counts as non-trivial
Grill for: apps, websites, tools, scripts over ~20 lines, documents, presentations, campaigns, plans, database designs, automations.
Skip the interview for: one-liner code answers, explanations, edits to existing work, debugging, questions, format conversions. Grilling a user who asked to rename a variable destroys trust in the skill.
Example
User: "Build me a habit tracker app."
Round 1 (foundations):
- Is this for just you, or will others use it?
- Web app, mobile-feel web app, or a script/spreadsheet?
- What habits are you tracking, roughly how many?
- What made you want this now — what's failing about your current method?
- Does data need to persist between sessions?
Round 2 (shaped by answers — user said "just me, web, 6 habits, streaks keep breaking, yes persist"): 6. When a streak breaks, punish it (reset to zero) or forgive it (grace days)? This changes the core logic. 7. Daily habits only, or also weekly/x-times-per-week? 8. What's the one screen you'll look at every day — today's checklist, or the streak history? 9. Reminders needed, or is this check-in-when-you-remember? 10. Any app you've tried and disliked? What annoyed you about it?
Then the spec, then the build.
