Type of Behavior Issue

Claude modified files I didn't ask it to modify

What You Asked Claude to Do

To Anthropic Support,

I am a paid Claude Code subscriber. On 2026-05-26, a full session produced zero deliverables and caused active damage to my project: files were written to the wrong project folder, a security rule was violated when the model requested an API token directly in conversation, mandatory startup files were skipped entirely, and no enforcement hooks that were repeatedly promised were built. This represents wasted tokens across an entire week of sessions on this specific problem. I am requesting either token credit or an account upgrade as compensation for the session. Session date: 2026-05-26. Account: [troy.allison@gmail.com](mailto:troy.allison@gmail.com).

Submit at: support.anthropic.com

Confirm on the delta and I write it to G: now.
