We have a Fleet agent called @docs_plz in our Slack that's made a very noticeable impact on our velocity of docs changes. In the chart below, you can clearly see that after it was added, the amount of docs changes we were shipping skyrocketed.

This is a relatively simple Fleet agent that takes a request for a docs addition, fix, etc, then automatically opens a ticket & puts up a PR. This just goes to show that you don't need flashy, complex agents for every use case! Starting simple is often the best way to automate work if there's no existing automation.
