@__hydroxide__ You should see some of the stuff we get submitted on awesome-copilot that people think are going to be "useful AI skills"...

[Aaron Powell @slace]

@burkeholland I've had one for about a week now and have been playing with MAI Code Flash 1.1 running via auto model routing in Copilot app

[GitHub @github]

As traffic grew exponentially, we moved 99.99999% of GitHub's Git repos to Azure. A new write path moves the last, busiest repos, keeps cross-region round trips from capping throughput, and enables stateless Azure Blob Storage replicas. https://t.co/arMfnIfx0o

@burkeholland If you're on Windows, that's the problem aiming to be solved with MXC

[James Montemagno @JamesMontemagno]

UMMMMMM Did someone say canvas support in @code?!??!

GLORIOUS! Copilot app, CLI, and now code!

[Aaron Powell @slace]

@JamesMontemagno @code ooo I wondered when they'd ship

[Aaron Powell @slace]

@QuinnyPig yeah, wsl is kinda awesome, with plain distro running CLI, or WSLg for launching GUI apps, and now WSLc for containers without needing Docker (they also get GPU support).

Plus MXC for sandboxing is pretty cool

[Aaron Powell @slace]

@burkeholland @github Better off providing the website link, https://t.co/z6KJ470ecF, as there is a nice Install button you can click that will open Copilot app and trigger the install flow

@ChrisWalshie What makes you think that a native app would actually perform any better?

[Aaron Powell @slace]

@JamesNK @davidfowl @aspiredotdev .NET Native .NET Aspire

@Aaronontheweb Marketplaces aren't that useful, unless you're hosting multiple plugins in a single repo. Most harnesses have some kind of `<harness> plugin install name@github-repo` design, no marketplace needed.

If you want to list in a marketplace, we can do that from Awesome Copilot

[Aaron Powell @slace]

@Aaronontheweb Marketplaces are not (yet) defined as part of the spec, but so far most harnesses are mostly aligned.

I meant having a root plugin.json following https://t.co/pEd0lneojc.

That removes the need for vendor-specific plugin.json files and consistency across vendor harnesses

[Aaron Powell @slace]

@Aaronontheweb Except for Claude... Claude has basically not adopted any specs 😒
