How to 10x Your Development Speed with Cursor AI: A No-Nonsense Guide

·7 min read·By Keying Wu

Hey there! Tired of wrestling with AI coding assistants that seem to have a mind of their own? I get it. When I first started using Cursor AI, I hit the same wall everyone does—loads of promises, but plenty of errors. But here's the thing: After months of trial and error, I've cracked the code to making Cursor AI actually work for production-level applications. This guide is based on insights from AI Jason's excellent work (credit where credit's due!) and my own hands-on experience. Let's dive in.

The Truth About Cursor AI No One Tells You: Strategic Planning

Here's the thing about Cursor AI that most tutorials miss: It's not about writing perfect prompts. It's about setting up the right foundation. Think of it like building a house. You wouldn't start laying bricks without blueprints, would you? Same principle applies here.

Your Pre-Development Checklist

0. Starting Point

# 1. Project overview 
xxxx 
# 2. Core functionalities 
xxxx 
# 3. Doc (Code example of third party API)
xxxx 
# 4. Current file structure 
use tree -L 2 -I 'node_modules|.git' to generate it after you initiated the project
xxxx 
# 5. Additional requirements
xxxx

1. Draft Your Initial PRD

First things first - create a rough draft that outlines:

  • Project overview
  • Core functionalities

Pro Tip: Don't worry about getting it perfect. This is just your foundation.

2. Research Package Requirements

Next, dive into the technical details:

  • Research compatible packages for core functionalities
  • Talk to Claude about potential libraries
  • Test quick proof-of-concepts to verify compatibility
  • Put the example code for API call in the Doc section of PRD

This step saves countless hours of trial and error later.

3. Let o1/Claude Design Your Project Structure

Here's where it gets interesting - leverage o1/Claude to:

  • Design an optimal project structure
  • Plan folder organization
  • Map out component relationships

Why This Works: Claude can analyze your requirements and suggest structures that scale well.

Prompt in this step:

[initial PRD]
Above is the project i want to build, how should i structure my project files? (try to create as few files as possible)

4. Final PRD with o1/Claude

Finally, have o1/Claude help write your detailed PRD by:

  • Expanding on your initial draft
  • Adding technical specifications
  • Creating comprehensive documentation

Real Talk: This four-step process might seem like overkill, but it's exactly what separates successful Cursor projects from frustrating ones.

Prompt in this step:

Help me adding details to the original PRD that give clear alignment to developers who will implement the project;
- dont create actual code, just the PRD
- including file structure & additional requirements into the doc
- including all documentations provided (with both example code & responses, those are important context)

This is how your final PRD should look like:

# YouTube Video Summarization App

## Project Overview
A Next.js 14 application that allows users to paste a YouTube URL and receive a summarized text with highlights. The app utilizes server-side rendering, Shadcn UI components for design, and Tailwind CSS for styling.

## Core Functionalities

### Home Page Input Box
**Description:** A centered input box for users to paste YouTube video links.

**Requirements:**
- Prominently displayed in the middle of the page
- Accepts full YouTube URLs and video IDs
- Validates URLs and extracts video IDs on submission

### Transcript Retrieval
**Description:** Uses YouTube Transcript API for downloading video transcripts.

**Requirements:**
- Handles cases where transcripts are unavailable
- Manages API limitations and errors efficiently

### Highlight Extraction
**Description:** Extracts 3 key highlights from video transcripts.

**Requirements:**
- Uses OpenAI's API for transcript processing
- Identifies and presents key highlights concisely
- Displays highlights at the summary's beginning

### Structured Summary Generation
**Description:** Generates structured video content summaries incorporating extracted highlights.

**Requirements:**
- Utilizes OpenAI's structured output with Zod schemas
- Ensures coherent and well-structured summaries
- Emphasizes highlights at the beginning

## Documentation

### Using OpenAI Structured Output

The application uses OpenAI's API for structured summaries using Zod schemas:
(Example Code)

## Additional Requirements

### General Guidelines

#### Component Placement
- All components go in `/components` directory
- Use kebab-case naming (e.g., `example-component.tsx`)

#### Page Placement
- New pages go in `/app` directory
- Use Next.js 14 app router

#### Data Fetching
- Perform in server components
- Pass data to client components via props
- Keep API keys secure in server components

#### Client Components
- Include `'use client'` directive
- Handle user interactions and UI state

### Technical Requirements

#### Next.js 14 App Router
- Utilize server and client components
- Optimize for performance

#### OpenAI API Integration
- Process transcripts and generate summaries
- Use Zod schemas for structured output

#### YouTube Transcript API
- Use `youtube-transcript` package
- Handle unavailable/restricted transcripts

#### Utility Functions
- Implement in `/lib/utils.ts`
- Ensure reusability and documentation

Implementation Strategy

Here's where most developers go wrong - they jump straight into coding. Instead, let's leverage your AI coding agent effectively:

1. Set Up Your Instructions

  • Place your final PRD in /instructions/instructions.md

2. Break Down Implementation

Now, in your Cursor composer, use this approach:

  1. Start Core Structure:
Let's build a [project name] based on @instructions.md.
Let's firstly build section 1.1
  1. Component-by-Component Build:
Great, now let's implement section 1.2
  1. Test & Iterate:
  • Review each component after implementation
  • Address any errors before moving to the next feature

Making Your UI Shine with V0

Here's a game-changing tip: Use V0 (Vercel's AI design tool) to enhance your UI.

The process is simple:

  1. Build core functionality first
  2. Copy component code to V0
  3. Generate enhanced designs
  4. Implement improved UI

Best Practices Cheat Sheet

Save this for reference:

Documentation Must-Haves

  • ✅ Clear project overview
  • ✅ Detailed functionality list
  • ✅ File structure map
  • ✅ API documentation
  • ✅ Component breakdown

Workflow Optimization

  • ✅ Break tasks into mini-steps
  • ✅ Test each component individually
  • ✅ Document errors and solutions
  • ✅ Use version control
  • ✅ Monitor AI usage costs

Common Pitfalls to Avoid

  1. Rushing the Documentation Don't skip the planning phase. It's tempting, but it will cost you more time in the long run.

  2. Overcomplicating Prompts Keep instructions clear and specific. More words doesn't mean better results.

  3. Ignoring Error Patterns Document your errors. They're not just problems - they're learning opportunities.

Final Thoughts

Look, I get it - all this planning might feel like overkill. But after countless projects, I've learned that a solid PRD isn't just documentation - it's your secret weapon for success with Cursor AI.

Remember:The goal isn't to write perfect prompts; it's to build better applications with less frustration.

Start with a clear plan, trust the process, and watch how Cursor AI transforms from a fancy code editor into your most powerful development tool. Now go build something amazing! Happy coding! 🚀
