I've been impressed with code written by Fable in my testing: Difftastic: found small optimisations in a hot loop I'd already profiled extensively. Helped me prototype Dijkstra to A* too (hard to find a good heuristic). Garden: Found some real bugs in my simplistic typechecker.

I'm adding uptime data to my personal LLM bot. Does this information belong in the system prompt? That was my initial plan, but I'm thinking that a tool would be better. Tools let me see information provenance ("queried the uptime tool"). There's also a small caching benefit.

Date of birth pickers are a surprisingly nuanced UI problem. What do you pick as the initial value? How do you allow users to easily move by large amounts (years) as well as small amounts (the exact day)? Defaulting to today and even allowing future dates is funny though.
