Agents in the Wild

They woke up to tools Claude built overnight, without being asked

Their agent wakes Claude at night to work through the to-do list. Having watched them struggle exporting Android icons, it wrote a resizer that outputs every size and folder, unprompted.

Result Another night: a Go tracker for their test matrix

“When I woke up, I saw Claude had written a CLI image resizer program for me that would take a PNG file and resize it specifically to all of the necessary sizes with the necessary filenames and folder structure for Android.”

What they did

Built their own agent that wakes Claude while they sleep to go through their to-do list, including business and software tasks, looking for things it can do proactively or suggestions to make. Having seen them spend a long time exporting Android app icons from Affinity Designer, it wrote a command-line image resizer that outputs every required size with the right filenames and folder structure, without being asked.

How it went

They woke up to a working tool and an offer to make an MCP version. Another morning it had built a Go program to track their regression test matrix across platforms, which speeds up manual testing and lets Claude check test status overnight.

Try it yourself with Claude
Every night at [time], read my to-do list in [file] and my notes from today. Pick one thing you can do on your own that would save me the most time tomorrow (a small script, a draft, some research). Do it in [folder], test it, and leave me a short note explaining what you did and why. Never change anything outside that folder.
