Build a new mobile game for my family arcade

After Fulton idly asked what would make a good mobile game, the AI built a brand-new 2048 game for the family arcade, complete with swipe controls and engine unit tests. It joined the site's existing chess offering as a shipped feature.

Redesign my circuit board with cheaper parts

A maker had the AI redesign his KiCad board, including selecting parts from JLCPCB's catalog and suggesting cheaper equivalent components that cut his bill of materials significantly. When assembly proved too expensive, the AI redrew the schematic around through-hole parts he could source himself.

Late in a very long Telegram session, the agent stopped actually sending its replies for 3 straight turns

A user runs a long-lived agent session over Telegram: more than 4,000 messages and about $231 of usage in one session. Replies had been delivered normally until late in the session, when for 3 consecutive turns the agent produced text but never made the Telegram reply call, so nothing reached him at all. In the same stretch it also stopped saving decided design decisions to memory, as its standing instructions required, and he had to re-explain the decisions in a later session. A manual service restart and a log review found the cause.

He catalogued his wife's inherited coin collection with an app that scans each coin and looks up what it is worth

His wife was left a massive box of coins by her late grandfather many years ago, and they had never catalogued them. He built an app that scans a coin and records its year, type, series and what it is made of, then checks websites for an approximate value and adds it to the collection. It can filter views, track where each coin is physically stored, and show graphs of the total value and the breakdown by coin type. There is also a virtual coin book he can flip through, using the photos he captured while scanning each coin in. For now the app is just for him.
