Add light mode theme support to Go TUI app
Takeaway: I'd start the prompt by mentioning that theme infrastructure already existed (DefaultTheme/DarkTheme, termenv auto-detect) so the agent didn't waste time rediscovering it from scratch.
3 sessions on cobra with a coding agent: the agent failed at least once in 1, and 1 finished without a human stepping in.

Takeaway: I'd start the first prompt by naming the exact command shape I want (`economist demo`, no flags) and flagging up front that I want a clean DataSource abstraction so future section/rendering changes don't create debt — that's what I ended up asking for mid-session anyway.
Takeaway: Next time I'd start by asking for a design/research doc first and only prototype code once that's reviewed, since the first TUI attempt got built too fast and had to be thrown away.
