Build a "subway or bus?" app during a transit outage

During a San Francisco subway outage, one user had Claude Code write a script to download the public real-time subway diagrams and build an image labeling tool, as first steps toward a web app.

Caution. Some tools needed manual tweaking.

Steps

  1. Find public data.
  2. Have it write a downloader.
  3. Build the tools one step at a time.

Prompt you can copy

Write a script that saves the public transit status image every minute.

What you get

A working data pipeline for the app.
