Sol adds comments when I use it, but it's not nearly as verbose as Opus 5/Fable. For the latter I'll often include an example of a comment it wrote, along with my own rephrasing, and tell it that "future readers will understand code context; good naming is the best documentation". This works alright if I include in the actual prompt, but annoyingly it often doesn't in CLAUDE.md or memory.
