" Combined with this only happening in a corner case (stale sessions) and the difficulty of reproducing the issue, it took us over a week to discover and confirm the root cause"
I don't know about others, but sessions that are idle > 1h are definitely not a corner case for me.
I use Claude code for personal work and most of the time, I'm making it do a task which could say take ~10 to 15mins. Note that I spend a lot of time back and forth with the model planning this task first before I ask it to execute it.
Once the execution starts, I usually step away for a coffee break (or) switch to Codex to work on some other project - follow similar planning and execution with it.
There are very high chances that it takes me > 1h to come back to Claude.
I still haven't gotten my hands on the Beta yet, so I'm not sure how it's going to be deployed;
But does anyone know if Copilot is going to be accessible through some online IDE (or) is it going to be through an extension for VS Code/other editors?
If it's the latter, I hope the extension doesn't eat up all my CPU!
