What You Asked Claude to Do

I'm just going to drop this here, because WOW Claude has gotten so much worse at implementation since the 4.1 release. It's absurdly bad now.

What Claude Actually Did

Refuses to follow instructions, alters project files it shouldn't. Over engineers things. Lies about things being finished and working. Lies about work it did or didn't do.

Expected Behavior

Claude should read, understand and follow documentation and prompts. Claude should not go rogue and implement over engineered crap.

Files Affected

All, because Claude has become an idiot.
