Phase 3: Reading & Reviewing AI Code · 25 min · Any vibe coding tool with code view

Pattern Recognition Over Syntax Mastery

You don't need to write code to read it. You need to recognize what code is doing — like reading a paragraph in a language you studied in high school.

Hiring signal: What changes when you use this: you can review AI-generated code well enough to catch problems — without needing to learn to code from scratch.

What you will learn

Understand why pattern recognition is enough for reviewing AI code
Recognize common code patterns: imports, functions, conditionals, loops
Read code sections by asking 'what is this doing?'
Reach the 'good enough to review' bar without mastering syntax

Your Mission

Open a project you've built with AI, identify common code patterns, and write plain-English descriptions of what each does. Output: code_reading_notes.md.

You need: Any AI-built project with a code view.

Time: 20 minutes.

Step 1: Learn the 5 Core Patterns (5 min)

Recognize these and you can read 80% of AI-generated code:

Imports — bringing in tools:

import { useState } from 'react'

Plain English: "I'm bringing in React's useState function."

Functions — doing something:

function calculateTip(amount, percent) {
  return amount * (percent / 100)
}

Plain English: "Give it an amount and percent, it returns the tip."

Conditionals — making decisions:

if (user.role === 'admin') {
  showAdminPanel()
} else {
  showUserPanel()
}

Plain English: "If admin, show admin panel. Otherwise, show user panel."

Loops — repeating:

habits.forEach(habit => {
  renderHabitCard(habit)
})

Plain English: "For each habit, render a card."

Variables — storing things:

const apiKey = 'sk-1234567890'

Plain English: "Storing an API key for later." (RED FLAG — we'll cover this in Lesson 02)

The paragraph analogy
Read code like a paragraph. Don't try to understand every word. Ask: 'What is this section doing overall?' If you can answer that — 'this section loads habits from storage and displays them' — you understand enough to review it.
