August 21, 2026 By malekimtiyajmca@gmail.com 20 min read

This complete Cursor AI tutorial covers 101 topics — from install and chat/agent modes to rules, prompting, stack workflows, MCP, model choices, and a final build-with-Cursor application project.

Course roadmap

1. Introduction to Cursor AI

Cursor is an AI-native code editor built for writing, editing, and understanding code with models in the loop. This series covers setup, modes, prompting, project workflows, stack-specific use, MCP, and a final build-with-Cursor project.

  1. Install Cursor and open a project.
  2. Practice chat, ask, and agent workflows.
  3. Add rules/MCP and finish the final project.

Learning path

Install + interface
Chat / Ask / Agent
Rules + context
Stack workflows
MCP + models
Final app with Cursor

2. What is Cursor AI?

Cursor combines familiar editor UX with AI chat, inline edits, multi-file agents, codebase context, and extensibility via rules and MCP.

Cursor in one line

AI-first code editor for generation, refactoring, debugging, and multi-file changes with project context.

3. Cursor AI Features

Feature depth grows over time — focus on the workflows you’ll use daily: edit, explain, test, and ship.

Feature map

Tab / inline suggestions
Chat & modes
Agent multi-file edits
Rules & memories
Codebase indexing
MCP tools
Terminal + Git help

4. Cursor vs VS Code

Cursor is forked from VS Code, so many extensions/keybindings feel familiar, with AI workflows built in rather than bolted on.

Quick compare

VS Code → general editor + extensions
Cursor → AI-native workflows on a VS Code base
Both → extensions, terminals, Git
Cursor → stronger multi-file agent + rules/MCP focus

5. Installing Cursor AI

Install from the official Cursor site, then sign in and open a folder to start.

  1. Download Cursor.
  2. Install and launch.
  3. Sign in and open a project folder.

Install checklist

Install app
Sign in
Open folder / clone repo
Confirm AI features available

6. Cursor Account and Setup

Account setup unlocks sync preferences and model access. Review privacy settings early.

Setup tips

Sign in
Pick default model if offered
Review privacy options
Import VS Code settings (optional)

7. Cursor Interface Overview

Knowing where Chat, Agent, and context pickers live speeds every workflow.

UI areas

Explorer / files
Editor tabs
Chat / Agent panel
Terminal
Command Palette
Status bar

8. Opening and Managing Projects

Prefer opening the repo root so indexing and rules apply to the whole project.

Project tip

File → Open Folder
Open repo root (not a subfolder) unless intentional
Use workspaces for multi-repo setups

9. Understanding the Cursor Editor

Treat Cursor like a power editor first — AI multiplies good navigation habits.

Editor habits

Go to symbol/file quickly
Split editors for diffs
Select code → ask AI about selection
Use peek / references

10. AI Chat in Cursor

Chat is ideal for explanations, small edits, and exploring options before large agent runs.

Chat uses

Explain code
Draft a function
Plan a change
Ask “why is this failing?”
Summarize a file

11. Cursor Agent Mode

Agent mode is for implementation tasks: “add feature X”, “fix bug Y”, “write tests”. Review diffs before trusting output.

Agent best for

Multi-file features
Refactors across modules
Fix + verify loops
Scaffolding new code

12. Cursor Ask Mode

Ask mode helps you understand a codebase safely — great before risky changes.

Ask mode tip

Explore architecture
Locate where X is implemented
Compare approaches
No write side effects

13. Cursor Manual / Edit Mode

Manual workflows pair human edits with inline suggestions and small chat asks — ideal when you know exactly what to change.

Manual workflow

You drive the edit
AI helps complete/explain
Smallest useful context
Commit often

14. Code Generation with Cursor

Specify language, constraints, file path, and acceptance criteria for better first drafts.

Generation prompt pattern

Goal
File/path
Inputs/outputs
Constraints (style, libs)
Edge cases / tests

15. Code Completion in Cursor

Accept suggestions you understand; reject noisy ones to keep training your own review muscle.

Completion tip

Write a clear comment/signature first
Tab to accept
Edit immediately if slightly wrong

16. AI Code Suggestions in Cursor

Suggestions are drafts — check APIs, null cases, and project conventions before accepting.

Review checklist

Compiles/types?
Matches existing patterns?
Secure defaults?
Missing error handling?

17. Writing Functions with Cursor

Ask for pure functions when possible; specify types and error behavior.

Function prompt

Write a pure function parsePrice(input: string): number
Throw on invalid
Add 3 unit tests
Match project lint style

18. Creating Classes with Cursor

Prefer small classes; ask Cursor to avoid god-objects and to follow SOLID where it fits.

Point to an existing component as a style reference for consistency.

Component prompt

Create Button component
Props: variant, size, disabled
Match styles in components/Button existing patterns
Include basic story/test if project uses them

20. Code Explanation with Cursor

Great for onboarding and reviewing unfamiliar modules — ask “what breaks if X changes?”

Explain prompts

Explain this function line by line
What are the side effects?
What are the edge cases?
Draw a short sequence of calls

21. Code Refactoring with Cursor

Ask for incremental refactors; require behavior preservation and run tests after.

Refactor prompt

Refactor for readability
No behavior change
Extract helpers where useful
Keep public API stable
List risks

22. Code Optimization with Cursor

Provide profiler clues or hotspots; ask for complexity and trade-offs.

Optimize tip

State the bottleneck

Prefer clarity unless proven hot path

23. Debugging with Cursor AI

Include reproduction steps and relevant file references — context beats vague “fix it”.

Debug pack

Error message + stack
Steps to reproduce
Expected vs actual
@file references
Recent related changes

24. Fixing Errors with Cursor

Ask the agent to fix and then explain what changed; verify locally.

Fix loop

Paste error
Apply fix
Re-run command
If fails, continue with new output

25. Understanding Error Messages with Cursor

Ask “what does this error mean?” before “fix it” when learning a stack.

Learning prompt

Explain this error in plain English
Likely causes (ranked)
How to confirm which cause
Then propose a fix

26. Working with Existing Code in Cursor

Map entry points, configs, and tests before large agent edits.

Legacy onboarding

Where is main entry?
How is config loaded?
How do we run tests?
What patterns repeat?

27. AI Code Review with Cursor

Use review prompts with severity labels; you still own the merge decision.

Review prompt

Review this diff
Flag bugs, security, perf, style
Severity: high/med/low
Suggest concrete patches

28. Writing Comments and Documentation with Cursor

Prefer documenting why, invariants, and public APIs over line-by-line noise.
