Agent says is made changes, but no real working changes diff #276282
Description
Type: Bug
- Ask agent to make change
- Agent says "Changed X file" with 0 diff changes (+0 -0)
- Open "Source control tab", no changes, no diff.
Using a Codespace in remote from Vscode on Windows with any model I think, but I was using "Grok code Fast 1", but also happened with Haiku 4.5
Examples from "Chat Debug View", I replace some string for privacy
