String to replace not found in file. & Error calling tool

[BumbleTree]

About 80% of all actions it tried to take failed
Left it for 15 minutes and and it went down a rabbit hole of failure

Same here.
It was working like a charm on the same code repository yesterday and today I fall in a lot of:

● Update(file_path: .vscode/tasks.json)…  
  ⎿  String to replace not found in file.  

● It seems there is an issue with directly editing the file. Here’s what I recommend doing manually:  
  1. Open the file `.vscode/tasks.json` in your editor.  
  2. Find the "InternalAPI" section (around lines 38-44).

same thing happening here.

SO: Windows WSL with Ubuntu
I'm CDing to a folder inside windows mounted and running it there

[forensicmike]

same thing here. it worked perfectly well the first day i tried it. ever since, its failed every time. could it have something to do with windows style newlines? unfortunately its unuseable for me in this current state (and VERY expensive)

Yes, this is happening way to often now. Maybe something in the update tool changed recently.

Having a lot of fun with Claude Code, however the amount of 'String to replace not found in file' errors are a bummer. Would be great if it could get tackled, or a workaround would be good as well since this is still a research project.

Same here. On Mac, it can't seem to update files and ends up running in circles trying to create bash scripts to do the same thing, wasting time and credits.

I just added the mcp mcp-text-editor from here, and claude code is working better. When it get's frustrated with it's default writer, it jumps over to this one for a while. I just wish I could toggle the built in mcp tools.
With uvx installed, you can add with:
claude mcp add mcp-text-editor uvx mcp-text-editor

Interesting find @adv-algos. I saw this in the update notes:

Maybe you could write a simple prompt:

For the rest of this session, always use mcp-text-editor when working with local files. Other methods are prone to errors, since the source is located on a Windows system with CRLF line endings instead of Linux' LF line endings.

Save it as /home/claudecode/.claude/commands/enableeditor.md or something, and execute it whenever you start a session? Just an idea.

This should be feeling better with newer versions of Claude Code. claude update or restart to update, and please open a new issue if you're still hitting this.

I only started getting these errors today. Same repository has been working fine for the past few weeks, but suddenly today it has fits where it can't seem to get a read on files. If I end the entire session and restart it'll usually do its "startup" reading correctly with no issues when I first hand it a task. However, after about 3-5 minutes it'll try to make some suggested updates and struggle to read files that it's already successfully read before. Very strange.

We've made further improvements here. Please let us know if feeling better with today's release
