How do I preinstall certain tools onto a Hosted Agent?

By default, the Hosted Agent I'm working with is not supporting yarn command but only npm. Sad, right?

Of course, I could have a step in my build pipeline that downloads and installs yarn via scoop or choco[latey] on each run, but I really don't like the idea of the build increase time for something that should be available to me out of the box.

So how do I preinstall the tools I need upfront?

You do not necessarily need to use a private agent -- you can run your builds in a prebuilt container. This way you can have control over a hosted agent.

resources:
  containers:
  - container: tests
    image: my/container:tests

jobs:
  - job: run_tests
    container: tests
    pool:
      vmImage: 'Ubuntu-16.04'
    steps:
    # actual build
    ...

This is the correct approach to install something on a build agent. If the increased time is a problem for you you could consider installing an agent on a machine of yours. But even if you use a private agent the approach to have some the installation done as a step of a build would be the correct approach

You don't. The hosted agent is fresh every time. There is nothing you can do to cache things on it.

If that's a requirement, you should install a private agent on a machine you control.
