[BUG] Every other 'edit' performed in a sub-agent ends up destroying the code

[guidedways]

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

• Ask Claude code fix something, such as a rename or removal of some function on a specific object
• If this 'function' is generic such that it exists on various different classes, Claude performs an edit in a separate sub-agent and removes every single occurrence

This started happening several versions back when Claude Code was improved to use sub-agents for edits. It gets them wrong every single time. I've given up on Claude Code in general but tested it again after several weeks and nothing has changed.

What Should Happen?

Please allow us to configure Claude Code to not use sub-agents for edits and refactors. I'm wall aware of the 200k context window and can manage it myself very well. I don't want claude to be using sub-agents as Claude as the primary agent is clearly unable to pass along the correct context because a) it does not read the file itself to begin with, b) the sub-agent is equally blind but worse at its job.
