Lovable prompt library
Seven prompts that cover the whole hackathon arc — from planning to demo readiness. Tap to copy.
A
Planning prompt
Use this first — make Lovable plan before it builds.
We are building a simple V1 MVP for a business decision-support app. Goal: Help a business user collect information, review it, classify it, and recommend the next action. Constraints: - Keep this as V1 - Do not overbuild - Do not add login, email automation, CRM integration, or advanced analytics - Prioritize the core user flow - Ask before adding complex features - Do not implement anything before planning first First, create a simple implementation plan with: 1. Problem summary 2. Target user 3. Pages needed 4. Data needed 5. User flow 6. Decision logic 7. V1 build phases 8. What to avoid building Do not build yet.
B
App shell prompt
After the plan is approved, build only the shell.
Now build only the V1 app shell. Include: 1. Home page 2. Intake form page 3. Result / recommendation page 4. Simple dashboard page Do not add login. Do not add external integrations. Do not add advanced analytics. Do not add email. Do not add team permissions. Keep it clean, simple, and demo-friendly.
C
Intake form prompt
Build the form once the shell is in place.
Now build the intake form. The form should collect: - request title - requester name - request type - description - urgency - business impact - supporting notes Add simple validation: - request title is required - description is required - urgency is required Do not add AI yet. Do not expand beyond V1.
D
Decision logic prompt
Add the rules that turn input into a clear recommendation.
Now add simple decision logic. The app should classify each request based on: - urgency - business impact - completeness of information - risk level The result page should show: - score - category - explanation - recommended next action Keep the logic simple and easy to explain.
E
AI decision-support prompt
Define the AI component before you build it.
We want to add a simple AI decision-support feature to our V1 app. Do not build yet. Help us define: 1. What user input the AI needs 2. What business criteria the AI should compare against 3. What score or category the AI should return 4. What explanation the AI should show 5. What recommended next step the AI should provide 6. What should remain human-reviewed Keep this simple and suitable for a hackathon MVP.
F
Scope control prompt
Use this when Lovable starts adding things you didn't ask for.
We are staying focused on V1 for the hackathon. Do not add new features unless they are required for the core MVP flow. Review your suggestion and classify it as: 1. Required for V1 2. Nice-to-have for V2 3. Not needed for this hackathon Only implement V1 items that directly support the final demo path.
G
Review before changes prompt
Run this in the last 30 minutes before demo.
Review the app for demo readiness. Check: - broken user flow - missing buttons - confusing screens - missing validation - unnecessary features - bad mobile layout - likely demo risks Give us a prioritized fix list before changing anything.
Tip
A good prompt names the user, the change, and what NOT to touch. Use these in order — A through G — and you'll stay on the V1 path.
