A successful vibe coding project is not one giant prompt. It is a sequence of constrained decisions: define the smallest useful product, give the agent a durable specification, build one vertical slice, verify it, and only then widen the scope. This tutorial works in Lovable, Cursor, Bolt, v0 and Replit even though their interfaces differ.
Write a single sentence: “For [specific user], this product helps them [specific outcome] by [mechanism].” If the sentence contains three audiences or five outcomes, split the project. An AI agent can generate many screens quickly, which makes overscoping feel productive until the flows contradict each other.
List one primary journey. For a booking tool: arrive → choose a time → enter details → receive confirmation. This journey is the acceptance test. Features that do not support it wait.
Use an all-in-one builder when learning or validating. Use an editor agent when the project needs custom architecture or must join an existing codebase. Avoid choosing a stack because it sounds advanced. For a content site, static HTML or server-rendered pages beat an elaborate client app. For an internal prototype, a hosted React app may be entirely appropriate.
Your first prompt should specify product, user journey, pages, data, design language, responsive behavior and exclusions. Keep it concrete:
Build a responsive appointment-booking MVP for independent physiotherapists. One flow: service → available time → contact details → confirmation. Pages: landing, booking, confirmation. Use a warm near-white background (#faf8f4), dark green accent (#174b3a) only for primary actions, Source Sans 3 body and Fraunces headings. 8px spacing scale, 12px radius, borders instead of shadows. Mobile first. Never use gradients, placeholder testimonials, emoji icons or invented integrations. Use local mock data first.
Notice what is absent: “beautiful,” “innovative” and “modern.” Values are executable; adjectives invite defaults.
Ask for the complete primary journey before settings, dashboards or polish. Use realistic sample data. Click every action. Refresh midway through the flow. Test empty and error states. If the slice is structurally wrong, adding pages multiplies the repair cost.
Do not respond with “fix everything.” Describe observation, expected behavior and a reproducible path: “On a 390px viewport, submit an empty form. The page scrolls horizontally and no field receives focus. Expected: inline errors, focus on the first invalid field and no overflow.” Ask the agent to explain the cause before editing. This separates a symptom patch from a durable correction.
If three fixes fail, stop the loop. Revert to the last known-good state, reduce the problem and inspect logs or browser errors. Repeated conversational patches often accumulate contradictory state. A clean rollback plus a smaller prompt is faster than a fourth guess.
Separate functional, visual and content changes. “Fix validation, redesign the cards and rewrite the hero” creates an unreviewable diff. Better: first define validation behavior, then review; next align card spacing to the token scale; then revise copy. Tell the agent what must remain unchanged.
Release to a narrow audience before buying traffic. Watch where people stop, what they misunderstand and which support questions repeat. Feed evidence back into the next prompt. Vibe coding is fast enough that observation — not generation — becomes the bottleneck.
Not to start, but technical literacy becomes increasingly valuable when debugging data, authentication, performance and deployment.
Usually 250–600 words: enough to define the product, primary flow and design system without specifying every implementation detail.
No. Define the whole product, but implement one end-to-end journey first. Expand only after that slice works.
