Since last night (I’m in Brazil, GMT-3), after an update, I’ve noticed that the agent mode has been hallucinating frequently and has completely lost adherence to prompts. The version was 0.48.9, if I’m not mistaken. Today I updated to 0.49. For example, you ask the agent: “update the translation keys only in the file: @en-US.json,” and it starts updating translation keys in `.tsx`, `.ts`, `.css` files, etc. Besides that, it seems to have lost the ability to locate itself within the project, even when you provide files in the context. It reviews the entire codebase and changes things that were already done and didn’t need any more modification (even when you clearly identify the error and explicitly tell it what it should or shouldn’t do). I’ve also noticed the agent frequently goes into loops, making and undoing changes it had already made in previous steps. Basically, the agent is in tilt mode, causing more harm than helping the project development. Over 100 calls were made just to fix the hallucination issues. There’s also the (old and persistent) error message saying it couldn’t connect and asking to check the internet or VPN. My internet is always fine, and I don’t use a VPN. Sometimes the issue is only resolved by restarting Cursor. **Error when calling tools:** It adds garbage to the tool commands, like `~[200`, and includes typos such as: `cd /d%3A/Cursor/project && npm run dev` `bash: cd: /d%3A/Cursor/project: No such file or directory` It opens a terminal popup instead of running in the context window, and then marks the task as completed, ending the interaction. What could be causing this kind of behavior in the agent? Did you recently make any changes to how the agent is supposed to act? I’ve been a Pro subscriber for months, and I’m seriously considering canceling my subscription for good. ---

On the first topic regarding it updating other files, are you providing context to the Agent? This should help limit the scope if you choose the specific file you’re trying to use as context. ---
