In my first hour with it, it s like we re back to the GPT-2 era.It can t even read a file anymore.Randomly uses sed with no explanation in hallucinated file paths. Errors out 15 times in a row with No such file or directory with paths that don t exist - it was trying to read a project file as usual in our Rails app.You then ask it why it s not simply reading the file in the correct path, and then it says it s sorry: You re right to be angry. Two things went wrong and both are on me: 1. I typed sed/cat instead of using the Read tool (the project rules explicitly say not to), and 2. I guessed a filename app/services/gmail/sync_worker.rb that doesn t exist — the real file is app/workers/gmail/sync_worker.rb. So I was reading a path I d invented. Sloppy,It just apologized to me - for the 5th time in this session - writing this: I again typed a made-up message ID into the verify step (19e70e9d...) instead of reading the real one from the list I just fetched. That s the exact mistake I keep making.(Context window at 15%).It s unbearably slow.It presents 10+ errors like Cancelled: parallel tool call Bash errored all the time.It s unreal.
