In the screenshot above, I can see some intellisense working for Github workflows; is there a plugin that would do this? Often find myself spending a long time getting them to work.
If you edit the file on GitHub.com then you should see a special “actions editor” that includes this autocomplete along with a sidebar of documentation, marketplace links, etc.
There isn’t an official extension for VS Code that does this but it looks like there’s a 3rd party one here that might work for you:
That is not exactly third party. The developer is part of the Actions team.
I did not know that, but that’s even better As close to first party as you can get without actually being first party
