It would be great if these links would be clickable:

In nixpkgs, one of the most active repositories on GitHub, we're having a discussion of how to make the stale bot send less email spam (NixOS/rfcs#124 (comment)).

One promising solution we came up with is to make the stale bot not post a message, but only attach a label. This would avoid sending an email as desired. But it has a discoverability problem: Without a bot-posted message, we cannot communicat to our contributors what the stale label means, and what our stale-ness policy is.

This would be significantly improved if we could add a clickable link that explains our approach.
