it fails a lot with "oldString not found in file. Make sure it matches exactly, including whitespace and line breaks". could be something we could fix with whitespace normalization?

@monotykamary commented on GitHub (Jun 21, 2025):

It also happened quite frequently in the old, we don't talk about anymore, opencode. It worked slightly better with patch, but at around 70k+ token context, it fails quite persistently on it and edit.

We actually have quite a few options: Aider has diff-fenced, avante.nvim has a poor man's cursor apply, and one guy made CEDARScript for Gemini back before it was cool. I think the core elements in CEDARScript could be something we can adapt for our case; like offloading precise line numbers, indentation counts, add whitespace to that, and syntax consistency to a runtime.

To add on, Gemini 2.5 Pro/Flash also worked with a lot less errors on Cline's XML tool calling, not sure whether we should consider that in the near future.

I experimented a while back with fixing this issue with Claude code by creating my own mcp server edit tool. It was quite hacky but ultimately the two conclusions I came to:

  1. As you alluded to @adamdotdevin the most success I found was with simply scrubbing the indentations (both in kind like tabs vs spaces, and in size like 2 vs 4 spaces). I used the "trimming" as a way to match / find the old content but then would still replace correctly with the real new content with actual indents provided by LLM.

  2. I am not sure if you use line numbers at all with the opencode edit tool but if you do, LLMs are horrid at line numbers. They often skip over empty lines so the line numbers they consider are off kilter. If you use line numbers at all, I suggest just using it as a safety net in case there are multiple matches in the same file of the old content string, but if only one is found anyways, the line numbers don't matter so just replace it. Or maybe you don't use line numbers and this doesn't matter.

Hope this helps!

@thdxr commented on GitHub (Jun 22, 2025):

@GitMurf so i'm going to implement an alternate edit tool for gemini - we have the ability to swap tools out automatically per provider

can you explain more what you mean by scrubbing the indentations? like you'd trim every line in the file, old string, new string and do the replace?

Great question! Sorry I wasn't very clear. If LLM passes back an "old string" to match on to replace of the following:

    const foo = "bar";
    const bar = "baz";

Then instead of looking for that string with the indentation, I would look for the following:

const foo = "bar";
const bar = "baz";

Now as you alluded to, you'd essentially have to trim the entire file indents too if you wanted to try and do a full string match on this successfully. But I thought that was excessive. So the way I did it is I start by iterating through the lines of the real file, trimming each line as I check it and look for a match to the first line provided by the LLM (const foo = "bar";) ... if I find a match at line 27 then I try matching lines 2...n (in my example above it would just be matching the next trimmed line of const bar = "baz";).

If there happened to be two of the same old strings in the file, this also by default would replace the first found occurrence so that you can instruct the user this is the expectation in the rare case they have the same content multiple times in the file.

TLDR:

  1. Split the old string match coming from LLM into array of lines.
  2. Trim the indentations from incoming LLM old string lines.
  3. Loop through real file lines looking for a match to the first line coming from LLM (trimming to match).
  4. When first line is found, then loop through the other lines provided to see if they also match trimmed.

The other thing to note is I actually instructed the LLM to provide its old content and new content info each as an array of lines to avoid needing to split the content string by line break.

Also I first actually checked for exact match and edited the file with exact match if found. I only did the trimming logic as a fallback if a match wasn't found.

Does this make sense? Let me know if you have any questions and also would be happy to review any code you put together.

Also @thdxr fyi it may be useful to allow the user to choose the tool to use as for me, gpt-4.1 also has been having some issues with the old string matching with edit tool so I could see other non Gemini models also want to still try this other implementation of edit tool.

@BigMitchGit commented on GitHub (Jul 5, 2025):

perhaps it'd be good to implement a separate edit model that the user can choose. One model for the reasoning and coming up with changes, and another model for the sole purpose of applying the edit.

Then let the user choose what model to use there (i.e. self-hosted fastapply, morph fast apply, relace instant apply, llama3.3-70b, or any other model) and make it do whole or diff edits similar to what aider does?

@nyawox commented on GitHub (Aug 7, 2025):

I suggest trying square-bracket tool call format from aider pr 3781 https://github.com/Aider-AI/aider/pull/3781

It uses a format like this
(snippets from my project)

[tool(ToolName, parameter="value", another_parameter="value")]
[tool(AnotherTool, param1="value1", param2="value2")]

with complex arguments enclosed in triple double quotes:

  • Arrays and objects: wrap JSON payload in triple quotes: """[...]""" or """{}"""
[tool(TodoWrite, todos="""[{"id": "2", "content": "Update config", "priority": "high"}]""")]

I just implemented this in my anthropic compatible proxy for claude code,
and now Gemini can consistently perform one-shot edits containing literal escape sequences (like \n) with ease.

it still doesn't solve the uniqueness issue, but it addresses the biggest problem with gemini, which is escape sequence handling (\n \t \r etc) https://github.com/google-gemini/gemini-cli/blob/3a3b1381950fb3aab09f71e0ad1662a4f77b3c43/packages/core/src/utils/editCorrector.ts#L704

I'm not sure if this is oldString/newString-related, but just since recently when switching from "plan" mode to "build" mode (Gemini Pro 2.5), I get this all the time:

Edit

The arguments provided to the tool are invalid: Model tried to call unavailable tool 'edit'. Available tools: invalid, bash, webfetch, glob, grep, list, read, todowrite, todoread, task.

If hitting /new followed by /session and selecting my session, Gemini Pro 2.5 can continue with editing files again in build mode.

@jaens commented on GitHub (Aug 9, 2025):

Auto-formatting code after the LLM outputs it will obviously break the replace-based editing in case the LLM's code style does not match the formatter's. (since now the context has different code than the file)

Even Anthropic's documentation makes this fatal suggestion - add a hook with a formatter... immediately after adding that, Claude Code's own edit tool started failing much more often.

🤦

@kurnevsky commented on GitHub (Dec 22, 2025):

Could it be related to the format of read tool?

Results are returned using cat -n format, with line numbers starting at 1

So LLMs don't get file content directly and have to reformat it to supply it to edit tool. I constantly have problems with indentation in edits which breaks languages with significant indentation.

EDIT: tried to remove line numbers completely, and so far have much better results with Devstral.

@kurnevsky commented on GitHub (Dec 22, 2025): Could it be related to the format of `read` tool? > Results are returned using cat -n format, with line numbers starting at 1 So LLMs don't get file content directly and have to reformat it to supply it to `edit` tool. I constantly have problems with indentation in edits which breaks languages with significant indentation. EDIT: tried to [remove line numbers completely](https://git.kropki.org/kurnevsky/nixfiles/src/commit/d8088ff67d1571d6a275c6514d73985f52b53a8f/modules/opencode/line-numbers.patch), and so far have much better results with Devstral.

opencode is pretty much unusable once you reach over a certain amount of context, every code search or whatever it's doing fails with oldString not found in content

Reporting the same issue on OC 1.1.19 with Gemini 3 Flash.
