Git is a distributed source control system. It's open source and you can use it to version source code on your drive and/or a remote git repository.

Github is one of the most popular git repository hosts. In addition to source repositories, it has other services like issue tracking and wikis.

A while back, Microsoft bought Github.

"Github Copilot" is a service you can buy (with limited free sku) from Github that adds AI capabilities to your Github subscription.

One of the ways you can use Github Copilot is by using the GitHub Copilot extension for VSCode. This extension lets you use chat inside VSCode in such a way that it can read and write code. It lets you pick which LLM model you want to use: Claude Sonnet, Opus, OpenAI GPT, etc., from the ones they support.

Note you don't need another subscription if you only use Github Copilot. They pay Anthropic, you pay Github. You _might_ want another subscription directly with Anthropic if, say, you want to use Claude Code instead.

"VSCode Copilot" isn't a thing. Some people might call Github Copilot extension for VSCode "VSCode Copilot".

Github MCP server lets AI tools like GitHub Copilot extension for VSCode, Claude Code, or any tool that supports MCP use your Github account to do things like pull requests, read issues, etc. Just using it from Claude Code would not use Github Copilot tokens, UNLESS you used it to work against your Github Copilot service. You would not need a Github Copilot subscription to use it for example to create a pull request or read an issue. But it would use your Github Copilot tokens if, say, you used the MCP from Claude Code to assign a task to Github Copilot. It uses githubcopilot domain because they built it mostly for Github Copilot to use, though MCP is an open standard so it can be used from any MCP-supporting AI tool.

Sidenote but I don't get why you would want to pay github to run Claude on your code.

Yeah github pays Claude but what's the point ?

Tighter (read better) integration with VSCode and Github than what you could get running claude code on the side.

Your question does raise a valid point - Github Copilot's value proposition is fairly limited in my opinion. Not to say worthless but limited and clearly varies depending on how Githubbey your dev workflows are.

The workflow that GitHub has for prompting agent inside the ide itself is by far and away the nicest and most intuitive I've used.

Claude's integration looked like trash in comparison.

Why would I lock myself into a single vendor when I can have access to all models.

Also the GitHub subscription is a very good price.

Yeah, the workflow is superb. That’s what I miss most using Claude in a terminal inside VSCode. It doesn’t integrate with VSCode native diff tools like the native VSCode (GitHub Copilot does. The Claude extension in non-terminal mode is crap.

From a user point of view there's no real reason for it, from an admin point of view if your team is already using Github Enterprise then deploying it is basically hitting a toggle switch, and it has some more fine grained controls about what it can or can't do compared to Claude Code.

Most corporations have Microsoft already greenlisted as a vendor.

Making it possible to buy something from Anthropic might require tedious paperwork for many of them.

you can also get a service contract via MS quite easily/cheaply, which mightnot help you with hard problems but does solve the easy ones. example: in earlydays we bought OpenAI API directly and via Azure; when we needed account service we got it immediately from MS instead of waitlists from OpenAI.

I use it because they offer absurdly cheap prices that they're clearly losing money on. I can get $1000 at API prices of Opus 4.6, for in the range of $2 my cost through copilot.

Holy moly

I guess it won't last long, abuse it as much as you can right now.

It's massively cheaper. Copilot charges per request, which with some clever prompting, can lead to huge amounts of work being done at fractions of the cost of Claude Code. Millions of tokens for mere pennies. MS must be taking a huge hit somewhere, because I'm probably getting 10-20x my value out of GH relative to CC.

I am not locked in to Anthropic, either. I can easily switch between GPT and Gemini models based on how I think each would perform in various scenarios. That's a big win. I use a lot of design with Opus, implement with GPT 5.4.

Also, Github Copilot CLI is pretty much at feature parity (for the stuff that matters) with Claude Code. Using both at work and home, I don't think there's much difference in features between the two. Maybe I'm not a super power user, and just a regular dumb user, but GH doesn't seem buggy and everything I think I'd want to do with CC I can do with GH.

How can I learn that clever prompting?

Try to pack as much clear work into your prompt as you can so you don't go back and forth.

Do hacks like “read prompt.md, and follow its instructions. When you’re done, read it again and follow its instructions.” And then you have some background process appending to the file to keep it warm and you just keep writing there?

You could do that. I was just trying to say that if you make your original prompt complete enough, and you have well-defined success criteria, you can tell it to keep going until they are met.

Agreed - my experience mirrors this.

There is a limit on how much copilot can do in one request, pretty generous but after some time vscode will say "this request is taking very long, do you want to continue" and that would count as a seperate request

> but after some time vscode will say "this request is taking very long, do you want to continue" and that would count as a seperate request

I don't think that's true. In VS Code, that's also configurable via the chat.agent.maxRequests setting.

There was absurd latency in the Copilot Opus 4.6 model on 1st and 2nd April which led to lots of my requests timing out with nothing to show though.

> chat.agent.maxRequests

"Maximum number of requests that copilot can make using agents"

I don't get how this setting is relevant?

I'm spending a literal fortune on CC - we also have GH Copilot but the devs imply that CC is better? Will the Github Copilot let us access skills and agent frameworks in CC?

Devs say a lot of uninformed things. With a heavy predisposition to hating the "legacy" monoliths that are Microsoft and by association GitHub.

Yes, Copilot supports skills. Practically all agents support very similar feature sets or are actively building up parity support if not already there. The only real difference between systems is the prompt and payment method. Copilot even allows you to use Anthropic's own skills repository: https://github.com/anthropics/skills

https://docs.github.com/en/copilot/concepts/agents/about-age... details the support for skills. https://docs.github.com/en/copilot/concepts/agents/copilot-c... details the CLI tool in general, which seems more or less on par with Claude Code's.

It's a bit rich to go around calling people uninformed because they prefer one harness to another, particularly when you are recommending GHC as comparable to CC.

Have you used the gh copilot cli? What would stand out most to you as gaps right now?

IME is is less capable of performing complex work, more frequently goes down blind alleys and needs correcting, that kind of thing. It's night and day vs CC.

And this has been comparing like for like with CC - say Opus 4.6 on the same reasoning effort? Hasn’t been my experience particularly but fair enough. I do tend to use them in different situations (CC outside of work).

Even if it is close, maybe GHC CLI has improved in the last month since I last used it, I know you didn't say it but calling people uninformed because they prefer one or the other is just wrong.

I’d agree, though maybe there’s a more charitable reading of the OP - “uninformed” is one of those accusations that it’s rarely very polite or fair to level against an individual but sometimes is reasonable against a group based on observation. My experience would be that it’s true that “devs says lots of uninformed things” - and I’d include myself in that. It’s been my experience that it’s particularly tough in this space at this time because:

1. Tooling is changing very fast but people tend to form sticky opinions (reasonably enough - there’s only so much time in the world).

2. It’s just hard to form robust objective opinions - you have to make a real effort to build test cases and evaluation processes and generally the barrier to entry there is pretty high.

So - I agree, calling people uninformed is not a great way to win them over, but maybe that’s the price of living in a world of anecdotes which become fixed in people’s minds.

That's probably because the 200k context window means that it'll end up compacting things sooner.

I've just had a chat with Copilot's Opus 4.6 go off the rails after compaction today.

Make it write a skill and rule hook for PreCompact to do a handoff that explains what was worked on, what to know, and what to do next. If it goes off the rails after compaction then it won’t be great in a new session either, and you want to make sure you maximize continuity or development will be unsustainable. A backlog.md and improvements.md workflow also helps with this (ticket numbers, descriptions, “focus on BACK-0075,” etc.)

It’s a bit rich to take the most negative interpretation of my statement, and moreso telling of your insecurities that you chose to be so offended.

And, ultimately, proving my point. Did you actually explain why you thought it’s superior? Or is it just because GitHub bad? Have you even tried it recently?

Uninformed devs is what makes this gravy train going. If everybody jumps on gh copilot it will end quick.

Unfortunately it’s self defeating to educate them.

Claude (and most other models) in GitHub Copilot still only have 200k context, with a hefty amount being reserved for some reason. It's 1M at many other providers.
