Two minimum viable agents (#482)

These are two agents which appear in the Agent Guidebook.

I was thinking it'd be good to make sure these are captured in the
official codebase so that we could begin to write tests against them and
then eventually find a way to import them **from this repo** into the
website itself directly.
