Daniel Griesser's Manage the Context Window is a great read, but it also feels slightly dated already — and that's not a knock on Daniel. It's just a sign of how fast this industry moves.
He built a custom Claude tool to offload investigation work into separate sessions, keeping the main context clean. Smart thinking. But what he home-baked is now being shipped as first-class features. Sub-agent delegation isn't a clever script anymore — it's table stakes. The industry caught up to him.
The core insight still holds though: context management is real, and it matters. Letting noise accumulate in your main thread is a performance drain you can't afford when the model degrades past that smart zone. I think about this constantly when using Claude Code — delegating to subagents, using agent teams, keeping each context focused on one thing. Ralph's whole design is built around it: each task gets a fresh agent and a clean slate.
The pace of all this is wild. Things that required custom tooling eight weeks ago are now just... the way agents work.
Worth a read.
