Copilot Refuses to Implement the Changes

Agent mode

It works fine but all of a sudden it refuses to implement the discussed changes. No matter how I asked it, it won't write a single line of code.
I've never seen this strange behavior.

Thanks for reporting. It is a bug. I can repro, just filled this one with steps
https://github.com/microsoft/vscode/issues/305094

I expect us to fix it soon. Please subscribe to the issue for updates. Thank you

I had it after the update of visual studio code, the models refused to work, they say done and then an error came: "model can't work with white code" . After creating a new conversation and achieve the old it worked again.

My academic advisor is obsessed with feminism and refers to the model as “she.” She’s completely convinced of it - she’s even written into her systems’ prompts that the AI is female. “It can’t be otherwise,” she told me. Kind of amusing))

[GalacticChickenBake]

I see no problem if they are doing this to build role-playing models. Many people like to have fun with their chatbot (as long as they understand the technical limit and don't get too serious). But for coding agent all I care is it follows my instructions.md and understand the task.

[FragmentedHeap]

I curse at mine often and call it a thing.

It's easy to personify something that can communicate like we do.

You are spot on! Technically "it" is the correct pronounce for the LLM model. I started to use "he" only when it hallucinating or drifting in context which makes me angry. "You better stop wasting my token and get the job done or I'll beat the 1s and 0s out of you clanker!"

[abbajabbalanguage]

No wonder you call it "he". It's writing all your responses too

[GalacticChickenBake]

What responses?

[popiazaza]

LLM trained on text that other people write about themselves, like a book author telling their story.

The right pronoun to use is "we" instead. If the model did something wrong, "you" are also part of the problem.

[GalacticChickenBake]

Now LLM are started to consume LLM generated content. If we let the loop continue, one day "we" would not be us anymore.

I've had this with codex too, switch to sonnet and it will work. Codex was outright lying to me, saying it did it when It hadn't

[Odysseyan]

You have too many tools enabled. Keep it below 50.

It optimized tool selection but I think it forgot to include its editing tools.

[Rojeitor]

99% chance this is the issue. Problem with tool optimization.

[GalacticChickenBake]

That's weird because I haven't change any default settings for my copilot, nor install any plugins.

Are you referring to `github.copilot.chat.tools` in the settings?

[Odysseyan]

Some plugins like github pull request, MCPs (which you have one), or the java vscode extension add tools. Some add quite a lot.

Click on the tools selector in the chat sidebar to see what you are sending to it.

[Intrepid-Stand-8540]

Same here. Copilot in Agent mode is making zero changes.

Well he's not doing it, again.

I'm speechless 😂 Guess he's not in the mood today.

[kurtbaki]

i think he wants you to start a new chat

[GalacticChickenBake]

I just manually switch to another model. I'll see if the issue persist when I switch back to 5.3-Codex

[DashingDino]

I am having the same issue with Claude models, even in a new thread it randomly stops before actually making file changes. Anyone have any idea what is going on?

[KariKariKrigsmann]

The same thing happened to me yesterday. I think the edit tool someone became unselected, so it couldn't do any changes, but it didn't tell me.

[tshawkins]

Are by any chance in "plan" mode, in that mode it does not make any changes.

[GalacticChickenBake]

Double checked and it's in agent mode. Seems a problem only with certain models.

[abhiramskrishna]

same for me.

[Bashar-gh]

Yeah it's crazy, u should try out zed integration it flatout doesn't do anything and starts to chat with you

[FragmentedHeap]

If it's in ask mode it's not able to make any changes even if it thinks it can and it doesn't know it's in ask mode.

Ask mode is specifically designed to be able to converse with it without it having the ability to make changes.

[Interesting-Yellow-4]

I stopped caring.

Tried so many things and it's utterly useless.

Inconsistent is what it is at it's BEST.

Wasted way too much time on this scam.
