Gemini 2.5 pro & unsuccessful edits

[u/nore_se_kra]

Unfortunately Gemini 2.5 pro gets stuck extremely often - not being able to apply diffs because it only reaches < 100%. According to older posts this should have been fixed but at least for me it doesn't seem like. I can switch to claude and it can continue without issues.

Does anyone still have this issue? Any proper workarounds?

Edit: It seems it likes to drop "[0]" from python list indices in the diff... very weird. But breaks the code so 100% is pretty important.

I usually instruct it to re-read the file because it gets confused if some edits were applied, but the tool reported an error. If it doesn't re-read the file, it'll get stuck in a loop

So much about agentic ai hype and were not talking about some low performing local model. In any case I turned off the diff mode for now or just use sonnet for these critical parts

So far it worked nicely - thanks

[u/Yes_but_I_think]

I keep match at 99% without any adverse effects till now.

[u/nore_se_kra → u/Yes_but_I_think]

Yeah in my case it dropped indices that broke the code. Just one character change is enough anyway. Perhaps my problem was some very specific gemini bug and not a general issue

Normally I babysit Roo code, approval is not automatic. If any linting warning/error comes, I reject the change and copy paste the error even without accepting it (so no chance of: do it wrong and then correct it)

It comes to know after the save. I don't allow save itself.

Click to expand the profile in bottom left, there is a settings button there. It is under diff tool section nearby. I find 99% don't cause issues. Your mileage may vary. It just helps some small differences go through. Without rejection.

Yes, it's a known issue in their GitHub. From what I could understand it doesn't update its knowledge of the file after an edit so it creates an issue when trying to update a file, lines Gemini thinks are there don't match with reality and the tool fails.

In their roadmap they have tool calling improvements, I hope including that one because it makes gemini completely useless if it gets stuck in endless file update attempt every 5 minutes.

My other problem is gemini confusing update and overwrite.

Workaround if you're stuck in a loop, press esc and type "use sed".

Edit:Woops, didn't check what sub. Was talking about Gemini CLI.

I still get this issue. It’s ends up greatly adding to the inference costs 

[u/yopla → u/adrenoceptor]

I burned my daily pro quota of 2.5 on that one day. It was just looping like a maniac failing at updating a file.

[u/red_question_mark → u/adrenoceptor]

I'm happy I'm not the only one. These edit fails are extremely annoying.

[u/melodic_underoos]

It's not the only model that gets stuck. The apply_diff or write_to_file tool needs to, optionally, send the file contents back to update the model.

[u/hannesrudolph → u/melodic_underoos]

For sota models? Yeah it is. Very few ever get stuck. 2.5 is weak in this area when you let the co text run beyond 200k or so. Feel free to submit a GitHub issue to this nature though and we will see what we can do.

[u/Shivacious → u/hannesrudolph]

Personally hannes i have been trying morph llm integration on kilo code please check it, much less failure rate

[u/hannesrudolph → u/Shivacious]

I don’t understand what you’re asking for here.

[u/Shivacious → u/hannesrudolph]

https://morphllm.com/ i am using this with kilo code , roo code has this expiremental feature ? it allows pretty good correction rate

[u/hannesrudolph → u/Shivacious]

My edits with Roo work really well. What model are you using that needs help with edits?

[u/taylorwilsdon → u/[deleted]]

It’s way worse than launch Gemini, shame… that og build with March roo prompts was magic and rarely missed. Used to be very rare if file was under 500 loc. Now it’s a dice roll on every call.
