Foundation Prompt Masterclass
Learn why the first prompt is the most important—and how to save 1,000+ Manus credits by getting it right from Day 1.
The Cost of Bad Prompts
A vague, incomplete prompt costs you 500+ credits in fixes. Here's what happens:
- •Manus builds something that almost works, but misses critical requirements
- •You spend 200 credits fixing the database schema
- •Another 300 credits redesigning the UI because you forgot to specify mobile-first
- •Another 200 credits adding authentication because you didn't mention it upfront
- •Total wasted: 700+ credits on rework
Real example: Building Manus Mate required 5,000+ credits through trial-and-error. You won't have to waste credits like that.
The Foundation Prompt Solution
A Foundation Prompt is a comprehensive, max-character template that specifies every critical detail upfront. It's like building a house on concrete instead of sand.
"A house built on sand will crumble. A project built on a weak prompt will fail."
— The Foundation Prompt Philosophy
What Makes a Foundation Prompt?
1️⃣Maximum Character Usage
Use Manus's full character limit to eliminate ambiguity. Don't leave anything to interpretation.
❌ Bad Prompt (50 characters):
"Build a SaaS landing page with pricing"
✅ Foundation Prompt (2,000+ characters):
"I want to build [SaaS_NAME] landing page that [VALUE_PROP]. **Project Overview:** Platform name: [NAME], Target audience: [WHO], Core problem: [PROBLEM], Value prop: [WHY_CHOOSE_US], Revenue: [PRICING_STRATEGY]. **Features:** 1. Hero section with [HEADLINE] + [CTA], 2. Social proof with [TESTIMONIALS], 3. Pricing with [TIERS]... **Design:** Style: [MODERN/MINIMAL], Colors: [PRIMARY + ACCENT], Mobile-first: YES. **Conversion:** Lead capture: [EMAIL], Exit intent: [YES/NO]. Build conversion-first. Test CTA at 75%."
2️⃣Business Logic & Requirements
Specify the why behind every feature. Manus needs to understand your business model.
- Target audience: Who is this for? (B2B SaaS agents, D2C consumers, etc.)
- Core problem solved: What pain point does this address?
- Revenue model: How will you make money? (Subscription, one-time, freemium)
- Success metrics: What KPIs matter? (Conversion rate, MRR, user retention)
3️⃣Technical Architecture
Don't make Manus guess your tech stack. Specify everything upfront.
- Authentication: [YES/NO] - [METHOD: Email/Google/Magic Link]
- Database: [YES/NO] - [WHAT_TO_STORE: Users, Products, Orders]
- API integrations: [LIST: Stripe, SendGrid, Google Maps]
- Payment processing: [STRIPE/PAYPAL/OTHER]
- File storage: [YES/NO] - [WHAT_FILES: Images, PDFs, Videos]
4️⃣Design & UX Preferences
Manus can't read your mind. Tell it exactly what you want the UI to look like.
- Design style: [MODERN/MINIMAL/PLAYFUL/PROFESSIONAL/ELEGANT]
- Color scheme: [PRIMARY_COLOR] + [ACCENT_COLORS]
- Target devices: [DESKTOP/MOBILE/BOTH] - Mobile-first: [YES/NO]
- Key user flows: [LIST_3_CRITICAL_FLOWS: Signup → Dashboard → Checkout]
5️⃣Testing Milestones
Tell Manus when to pause and let you test. This prevents building on broken foundations.
"Build this step-by-step, starting with authentication and database schema. Test at 25%, 50%, 75%, and 95% completion. Ask clarifying questions before proceeding."
