I just want a better way to invalidate old context... It's great that I can fit more context, but the main challenge is claude getting sidetracked with 10 invalid grep calls, pytest dumping a 10k token stack trace etc.... And yes the ability to go back in time via esc+esc is great but I want claude to read the error stack learn from it and purge from its context or at least let me lobotomize ot selectively... Learning and discarding the raw output from tool calls feels like the missing piece here still.

Vscode recently rolled out checkpoints where you can go back to a previous state of the conversation. But it's still not enough.

We honestly need to be able to see exactly what's in the context and be able to manually edit it.
