Feature request: Github Copilot?

[anderssv]

Is it possible? I am not familiar with their APIs etc.

Due to corporate policies it is the only LLM (service) that we can use on our codebases.

[michaelneale]

@anderssv yeah would love this - as far as I know copilot models are not available yet via api (would need to ask microsoft for this). Would be good to put in a feature request with them as I agree would be great.

[anderssv]

Seems they just released a Language Server SDK, is that a viable route? https://github.blog/changelog/2025-02-10-copilot-language-server-sdk-is-now-available/

[anderssv]

Would be really nice as Copilot now have support for both Gemini and Claude too. 😄

FYI Copilot uses an OpenAI compatible API, but has special auth. If someone were to build this provider there is a reference python implementation in LiteLLM that was just merged:

https://github.com/BerriAI/litellm/pull/8577

I expect one could copy the existing OpenAI provider with the custom auth mechanism from that PR and things should work!

I am in the same boat that for legal reasons we can also only use GitHub copilot and I would love to use this

[dinhphieu]

Some guys at aider made some workarounds exposing the internal Copilot API in VSCode as a proxy

Not sure in the long run if it's worth it (it could break anytime), and on the legal side if it's even ok but worth taking a look if you're interested

While we wait (totally understand, wish I had the time to help), I recommend checking out VSCode Copilot Agent mode. It is similar in certain aspects, and getting ok results with it pointing it at a folder of Java/Kotlin projects: https://code.visualstudio.com/blogs/2025/02/24/introducing-copilot-agent-mode

[rockwotj]

I added support for this in https://github.com/block/goose/pull/1926 if anyone wants to help test

[BenceBakos]

@rockwotj Can I help testing it?

I'm not set up for rust development, but I suppose it's not that hard to build it.

• clone
• checkout the branch
• execute some building command that, after burning down my decade old I3, gives me a binary?

Or just simpler to wait for someone with dev env?

[rockwotj]

Yeah @BenceBakos some being cargo build --release. You'll need a working rust toolchain setup, which is pretty painless with https://rustup.rs/

[BenceBakos]

@rockwotj

cargo build --release:

...
  = note: /usr/bin/ld: cannot find -lxcb: No such file or directory
          collect2: error: ld returned 1 exit status
          

error: could not compile `goose-server` (bin "goosed") due to 1 previous error

[rockwotj]

I am not sure how your system is setup. github.com/copilot might be good at resolving. Assuming you're on linux you are missing libxcb

sudo apt-get install libx11-dev

Might do the trick or you need another system dependency.

You could also just build the goose cli and not build the server which I guess needs X11 support for something...

[BenceBakos]

@rockwotj

I did:

sudo apt-get install libx11-dev

then I got error:

error: rustc 1.79.0 is not supported by the following packages:
  [email protected] requires rustc 1.81.0

Either upgrade rustc or select compatible dependency versions with
`cargo update <name>@<current-ver> --precise <compatible-ver>`
where `<compatible-ver>` is the latest version supporting rustc 1.79.0

did this:

rustup update stable

And now I'm getting error:

I got the same error:

error: could not compile `goose-cli` (bin "goose") due to 1 previous error                                                                                                       

The fix was to install libxcb1-dev

sudo apt install libxcb1-dev

[BenceBakos]

@SoAG did you test it? I am still unable to build it.

[deemkeen]

i would love to have this feature in goose
