A good vibe coding prompt is not magic language. It is a compact spec. The agent needs context, boundaries, acceptance criteria, verification steps, and a definition of done. Once you learn that format, prompts stop feeling like wishes and start behaving like tickets.
The base prompt format
Use this shape for almost every task: goal, current context, exact change, constraints, verification, output format. That may sound formal, but it saves time because the agent does not have to guess what matters.
For example: 'On the pricing page, add annual billing copy under the Pro card. Do not change prices or checkout paths. Run the build. Report changed files and any failing checks.'
Prompts for new features
Feature prompts should include the user story and the non-goals. Non-goals are underrated. They stop the agent from adding dashboards, migrations, or dependencies you did not ask for.
A strong feature prompt says: 'Add saved drafts for the video script tool using local storage only. No backend. Show saved drafts in a compact list. Include empty state. Verify on desktop and mobile.'
- Name the user and outcome.
- Name the storage layer.
- Name the screens that should change.
- Name the checks that prove it works.
Prompts for bugs
Bug prompts should ask for investigation before edits. Give the error, route, expected behavior, actual behavior, and reproduction steps. Then ask the agent to identify the likely cause and propose a minimal fix.
Do not start with 'fix this' if you do not understand the blast radius. Start with 'investigate and report before editing' for sensitive bugs.
Prompts for payments and auth
Payments and auth need a stricter prompt. Tell the agent not to print secrets, not to invent keys, not to bypass checks, and not to weaken validation. Ask it to separate local proof from production proof.
The prompt should end with a gate: 'If a real Stripe key, customer data, or production database write is needed, stop and ask.'
Prompts for final review
The best final prompt is a review request, not another build request. Ask for security risk, quality risk, mobile risk, SEO risk, accessibility risk, and missing tests. Then ask for a prioritized fix list.
This mirrors Google's people-first content logic: useful work is not just produced; it is evaluated for whether it helps the intended audience complete a goal.

FAQ
What is the best vibe coding prompt? The best prompt is specific, bounded, and verifiable: goal, context, constraints, acceptance criteria, and the exact checks to run.
Should I paste the whole codebase into a prompt? No. Let the coding agent inspect the repo. Give it the routes, files, screenshots, and symptoms that matter.
How do I stop an AI agent from overbuilding? Write non-goals and constraints into the prompt. Tell it what not to change, what not to install, and when to stop.
