Re: this section:

As a technical writer, you should stay close to the teams whose work you are documenting. Listen out for any code, SDK, or product changes that may require action. When you hear that a tool may be deprecated, start communicating.

It just assumes that nobody will ever proactively reach out to the technical writer about deprecations, which is entirely true in practice, but just feels so sad to acknowledge. Please keep your content and document management team(s) in the loop!
