This is basically my workflow. Claude Code for short edits/repairs, VSCode for long generations from spec. Subagents can work for literally days, generation tens of thousands of lines of code with one prompt that costs 12 cents. There's even a summary of tokens used per session in Copilot CLI, telling me I've used hundreds of millions of tokens. You can calculate the eventual API value of that.

Just at the absolute best deal in the AI market.
