> This cut-and-paste workflow felt clunky and made it arduous to work through an idea while keeping track of the current plan.

I mean, it is, and if that were the workflow I’d be very fed up of it by now, but the plan mode in Claude’s VS Code extension has supported select and annotate directly since at the very least early 2026.

oh interesting! I haven’t used vscode for anything meaningful since shortly after leaving GitHub (2023). I generally find it overwhelming but codex added the annotations too and I love it.
