I've been pushing the context window well into the 400-600k+ token range lately (mostly Opus 5). I prefer not to since I'm aware of context collapse, but I've been leaning that way lately.

Lately, I've been finding that the game of telephone of handoffs causes more mistakes than just letting the session run longer. Not too mention the wasted time waiting for agents to poke around as they bootstrap a new session from the handoff.

Of course, I still have handoffs for the large-scale plan being accomplished, but I've been having better results letting an agent finishing what it starts. The game of telephone is a painful waste of time when it goes wrong, which is far too often for me.
