Use AI to Read Other People's Code (a Big Real-World Skill)

Real coding jobs are way more about READING code than writing it. Open source projects, your team's code, old code you have to maintain — you read way more than you write. AI helps you understand unfamiliar code fast.

Real examples

• 'Explain what this function does in plain English.'
• 'Walk me through this file and tell me what each section is for.'
• 'Compare these two functions — what is different about them?'
• 'I am new to this codebase. Where should I start reading to understand it?'

Try it yourself

Find a small open-source project on GitHub. Pick one file (under 100 lines). With AI's help, understand what it does. Then close the AI and try to explain the code to yourself. Notice the gaps.

Practice this safely

Try this with a school, hobby, or family example where the stakes are low. Use the AI output as a draft you can question, not as the final answer.

1. 1Ask AI to explain code reading in plain language, then underline anything that sounds uncertain or too broad.
2. 2Give it one detail from "Use AI to Read Other People's Code (a Big Real-World Skill)" and ask for two possible next steps plus one reason each step might be wrong.
3. 3Check open source against a trusted source, teacher, adult, expert, or original document before you use it.
