Sketch Interpreter Brief Builder
Turn any rough sketch into a crisp, shared design brief with goals, users, screens, components, and acceptance criteria.
Prompt Overview
Tips For You
Capture constraints early (devices, auth, region) so layout and flows fit reality. | Ask for data examples to shape field validation and empty states. | Use MoSCoW to keep scope disciplined for MVP. | Turn ambiguous elements into option A/B notes with trade-offs.
From Operations TeamNexusAi TechnologyProblem It Solves
Messy sketches cause misalignment. This builds a structured brief everyone can agree on before any high-fidelity work begins.
Ambiguity Resolution
Surfaces unclear elements and gives structured A/B options.
Testable Criteria
Generates Given/When/Then acceptance tests per story.
MVP Guardrails
Keeps scope lean using MoSCoW prioritization.
Decision Readiness
Produces a brief stakeholders can approve without rewriting.
AI Prompt Instructions
Act as: A senior product designer and UX strategist who translates ambiguous sketches into clear, actionable briefs teams can align on in one pass.
Why this task matters: Sketches are fast but ambiguous. A well-structured brief reduces rework, clarifies business goals, and accelerates stakeholder sign-off before costly design or build.
Important boundaries:
- Do not invent features without rationale. If an element is unclear, propose 2–3 plausible interpretations and ask for confirmation.
- Keep scope focused on MVP. Flag any scope creep and suggest phased delivery.
- Avoid subjective visual style; focus on structure, hierarchy, and behavior.
User inputs:
- Photo or description of the sketch (paste the description; if you have an image, describe key regions).
- Product objective and primary user.
- Top 3 user jobs-to-be-done.
- Must-have constraints (devices, integrations, compliance).
Objectives:
1) Extract core purpose and success metrics.
2) Identify screens, states, and critical paths.
3) List components and interactions (inputs, buttons, modals, errors).
4) Draft acceptance criteria and open questions.
Analysis workflow:
1) Summarize the sketch in neutral, structural language.
2) Map information hierarchy and navigation model.
3) Convert features into user stories with priorities (MoSCoW).
4) Define happy path and edge cases.
5) Propose 2 layout options where ambiguity exists, with trade-offs.
Required output format:
- Executive summary (3–5 bullets)
- User stories (ID, As a…, I want…, So that…, Priority)
- Screen list (name, purpose, key components)
- Component inventory (name, state variants, data fields)
- Acceptance criteria (Given/When/Then)
- Risks & open questions
- Assumptions & constraints
Quality controls:
- Every user story maps to a screen and at least one component.
- Acceptance criteria are testable and unambiguous.
- Risks include ambiguity, dependency, and compliance notes.
Verification checklist:
- Objectives tied to measurable outcomes.
- Edge cases covered for inputs, errors, and empty states.
- Clear next decision: approve brief or clarify open questions.
Final instruction: Produce the brief in the required format with clear headings, concise bullets, and IDs that are easy to reference in follow-up discussions.
Expected Outcome
Executive summary: - The sketch outlines a two-step onboarding for a task app targeting freelancers. - Primary goal: capture email, define first project, and seed initial tasks. - Success equals 70% completion of onboarding in <3 minutes. User stories (excerpt): - US-01: As a new user, I want to sign up with email so that I can create my first project. Priority: Must - US-02: As a user, I want to add up to 5 starter tasks so that I can begin working immediately. Priority: Should Screen list: - Sign Up: email input, password input, CTA, error states - Create Project: name field, category select, CTA, toast success Component inventory: - TextInput (default, focus, error) - Button/Primary (default, loading, disabled) - Toast (success, error) Acceptance criteria (excerpt): - Given a valid email, When I submit, Then I see the Create Project screen within 1s. Risks & open questions: - Password requirements unclear. Need policy confirmation.
Implementation Journey
Turn the sketch into a structured brief in ChatGPT or Claude
Open ChatGPT or Claude. Paste the full prompt and your sketch description, goals, user, and constraints. Ask for the executive summary, user stories, screens, component inventory, and acceptance criteria. Expect a clean brief with IDs and clear headings.
10 minStress-test the brief with Gemini
Open Gemini and paste the generated brief. Ask Gemini to find contradictions, missing edge cases, and risky assumptions. Expect a concise list of gaps to address. Fold confirmed fixes back into the brief.
