The new Amp coding agent from Sourcegraph basically just figured out that Claude's new Subagents feature can be used to give users an unlimited context window. They've really gone out of their way to streamline this process and make it a core feature of their new product. Try using PocketFlow with Amp and let me know how it goes.

They explained it in this video recentlyhttps://www.youtube.com/watch?v=p9Kuk_Fr1Xk

Full disclosure: I made an Amp account a few days ago but I haven't actually used it yet.
