I Built a Real Tool in Replit Without Installing Anything

The agent wrote, ran, and deployed a small app from one paragraph. The catch was understanding it later.

I needed a scraper for a one-off task and didn't want a local environment. Replit's agent built it.

I described the input, the output, and the edge cases. It shipped a running app in a browser tab.

The code pulled in libraries I didn't recognize. I asked it to explain each before I trusted the output.

Debugging meant describing the error back to it, which is a different skill than reading a stack trace.

Great for a tool you'll run a few times. For something permanent, learn the code it wrote.

A research paper I'd been avoiding became a 25-minute walk. The workflow is dumb, and that's why it worked.

Not zero-inbox. A loop that decides what is real so I only touch email twice a day.
