Do you use a linter like the ansible vscode extension?

I used to hate writing ansible, and yaml, until I installed the ansible lint vscode extension, and everything became much, much easier.

Later on, when I was working on a docker-compose, I noticed that the vscode yaml extension (which the ansible extension pulled in as a dependency) caught errors. It's quite intelligent, able to spot errors exactly like what you mentioned, where the yaml syntax is correct, but the docker-compose, or the ansible syntax is wrong.
