Why this matters

Vibe coding means describing software in plain language and letting the model write it. You don't need to read the code to judge whether it works.

The 20-minute experiment

1. 1Think of the smallest useful tool you'd like: a tip calculator, a countdown, a unit converter
2. 2Describe it in three sentences, as you'd explain it to a friend, and ask for a single working page
3. 3Try it with real numbers. When something's wrong, say so in plain English rather than fixing the code
4. 4Ask for one change and watch it update

Build me a single working page that does this. Plain and simple, no styling flourishes. I'll tell you what to change after I try it.

• A tiny tool described in three plain sentences
• Something working produced on the first attempt
• You tested it with real numbers
• One change requested in plain English and applied correctly
