Claude Skills Guide

Build a SaaS MVP with Claude Code Skills

Building a SaaS MVP requires speed, reliability, and the right toolchain. Claude Code skills provide specialized capabilities that accelerate every phase of MVP development, from UI design to automated testing and document generation. This guide shows you which skills to use and how to combine them effectively.

Planning Your MVP Architecture

Before writing code, define your core feature set. A typical SaaS MVP needs user authentication, a database, API endpoints, and a frontend interface. Claude Code skills handle the repetitive parts of each layer, letting you focus on business logic.

The /supermemory skill helps you organize research, competitor analysis, and feature requirements. Use it to maintain a searchable knowledge base of your product decisions:

/supermemory
Store the following MVP requirements:
- Core features for v1: user auth, dashboard, billing integration
- Tech stack: Next.js frontend, Express API, PostgreSQL
- Target user: small team project managers
- Key differentiator: real-time collaboration on task boards

This creates a persistent context that Claude can reference throughout development sessions.

Frontend Development with the frontend-design Skill

The /frontend-design skill generates UI components, layouts, and responsive designs. For an MVP, you need clean, functional interfaces without spending weeks on design.

Describe your component requirements directly:

/frontend-design
Create a responsive SaaS dashboard layout with:
- Collapsible sidebar with navigation links
- Top header with user avatar and notifications
- Main content area with a 12-column grid
- Mobile-first approach with Tailwind CSS
- Dark mode support via CSS variables

The skill outputs production-ready HTML, CSS, and JavaScript. It supports Tailwind CSS, custom CSS frameworks, and component libraries. For a SaaS MVP, generate your landing page, authentication forms, and dashboard views directly from descriptions.

Pair this with the /canvas-design skill if you need mockups or promotional graphics. Generate social media images, app screenshots, and feature highlights without leaving your development environment.

Backend and Database Setup

For backend logic, the /tdd skill proves invaluable. Write your test cases first, then implement the feature:

/tdd
Write tests for a user service with these requirements:
- create_user(email, plan) creates a user with is_active=True
- Pro plan users get a 30-day trial period
- Duplicate email addresses should raise a ValidationError
- Password must be hashed before storage

Use pytest. Include edge cases for invalid email formats and empty passwords.

The /tdd skill generates comprehensive test coverage including edge cases you might overlook. This matters for MVPs where bugs damage early user trust.

A sample test structure:

def test_create_user_sets_active():
    user = create_user(email="test@example.com", plan="pro")
    assert user.plan == "pro"
    assert user.is_active is True

def test_pro_plan_sets_trial_period():
    user = create_user(email="trial@example.com", plan="pro")
    assert user.trial_ends_at is not None

def test_duplicate_email_raises_error():
    create_user(email="dupe@example.com", plan="free")
    with pytest.raises(ValidationError):
        create_user(email="dupe@example.com", plan="free")

PDF Generation and Document Handling

SaaS products often need PDF functionality: invoices, reports, contracts, or exports. The /pdf skill handles both reading and creating PDFs:

/pdf
Generate an invoice PDF with:
- Header: "Invoice #INV-2026-001"
- Bill To: Acme Corp, billing@acmecorp.com
- Line items table: [Product License: $99/mo x 1, Professional Support: $49/mo x 1]
- Subtotal, tax (8%), and total sections
- Payment terms: Net 30
- Footer with company contact info

Save as invoices/INV-2026-001.pdf

For MVPs, automating document workflows eliminates the need for expensive third-party invoice and contract services during early stages.

Testing and Quality Assurance

The /webapp-testing skill automates browser-based testing. Use it to verify that your MVP flows work end-to-end:

/webapp-testing
Test the user signup flow on http://localhost:3000:
1. Navigate to /signup
2. Fill in email: "test@example.com", password: "secure123"
3. Click the "Create Account" button
4. Verify redirect to /dashboard
5. Verify the welcome message contains the user's email
6. Take a screenshot of the final state

Report any failures with the element that was not found.

Run these tests before each deployment. The skill captures screenshots and logs, helping you debug UI issues quickly.

The /tdd skill complements this with unit and integration tests. Together, they provide coverage across all layers of your MVP.

Spreadsheet Data Exports

Many SaaS products need spreadsheet exports for admin dashboards or analytics. The /xlsx skill creates and manipulates Excel files:

/xlsx
Create a monthly analytics export spreadsheet with two sheets:
- Sheet 1 "User Summary": columns for User ID, Email, Plan, Sign-up Date, Last Active
  Include 3 sample rows for testing
- Sheet 2 "Revenue": columns for Month, New MRR, Churned MRR, Net MRR, Total MRR
  Include last 3 months of data

Save as exports/analytics-march-2026.xlsx

This covers admin data needs in your MVP’s early stages without building a custom export system.

Deployment Configuration

For infrastructure files, describe your requirements to Claude Code directly:

Write a Dockerfile for a Node.js API that:
- Uses node:20-alpine as base
- Installs only production dependencies
- Runs as a non-root user
- Exposes port 3000
- Starts with "node server.js"

Example output:

FROM node:20-alpine
WORKDIR /app
COPY package*.json ./
RUN npm ci --only=production
RUN addgroup -S appgroup && adduser -S appuser -G appgroup
USER appuser
COPY . .
EXPOSE 3000
CMD ["node", "server.js"]

Putting It All Together

Here is the workflow for building your SaaS MVP with Claude Code skills:

  1. Research: Use /supermemory to store requirements and competitive insights
  2. Design: Generate UI components with /frontend-design, create mockups with /canvas-design
  3. Develop: Write tests first using /tdd, implement features to pass them
  4. Documents: Build PDF generation for invoices and reports with /pdf
  5. Test: Run /webapp-testing for end-to-end user flows
  6. Data: Use /xlsx for exports and admin features
  7. Deploy: Generate infrastructure config files directly in Claude Code

Each skill addresses a specific bottleneck in MVP development. Start with the core loop of design, test, and build, then add skills as your product needs them.

When to Add More Skills

As your MVP grows, introduce additional skills:

The skill system is modular. Add capabilities when your product requirements demand them, not before.

Building a SaaS MVP is a sprint, not a marathon. Claude Code skills eliminate busywork across the entire stack, letting you ship faster with confidence. Focus on your unique value proposition and let the skills handle the scaffolding.
