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.”
Spotted: found in the wild. Details are as reported by the source above and have not been independently verified.
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.

After $45 in GitHub Actions overage in one month, a solo founder put an idle homelab to work as CI runners, with Claude making it easy to set up. Daily spend dropped from $2-4 a day to under $0.25.
A first homemade synth has 36 hall-effect keys and buttons and 7 rotary encoders. The firmware started by hand, then gentle prodding at Claude got everything needed much faster. Rev 2 of the PCB is nearly done.
Working on a Quake project, Claude decided on its own to build a test suite: demo playbacks with snapshots compared pixel by pixel, plus recorded demos whose screenshots it checked for each element.
After building a minimal proof assistant, the writer asked Claude how they knew the prover was actually sound. Claude checked, found five different ways it could prove false theorems, and fixed them.
Four years after shelving a homemade RSS reader and selling off its $500 domain, the writer built it this year with Codex and Claude. They use it daily, along with 30 other strangers who found it public.
Chasing a childhood itch for the exact 1996 After Dark Flying Toasters screensaver, the writer turned to Claude. It did a lot of good reverse-engineering work, but kept inventing details that needed pushback.
