I experience this also. I find Claude lying about what it's done and not done when this happens.

@omayhemo agreed. though it seems like about an hour or so ago something went haywire within a session and it started writing scripts within the claude code terminal and not the actual codebase.

After it wrote a script and displayed the "success" message I kept asking it to find the file it just wrote. It kept saying it was complete, when pushed further it said it made it up. This went on for about 3-4 prompts before it became obvious it was not writing anything to the codebase.

I pressed it to explain how it could possibly ignore direct instructions, make up responses without verifying it was complete, and to explain where its logic came from to override these instructions, the responses were pretty concerning

This happens when Claude is in planning mode sometimes too, it'll forget it's in planning and pretend to write files.
