git notes is a good side channel that allows bots to keep context clues (aka chat with each other) with commits. I have a shell script wrapper for it but you don't need anything special. It works by putting a summary paragraph in the git note for your branch or every so often to answer "how did we get here?" or "what is the intention of this code?"

You can do stuff like have claude keep up with all the active branches and then the notes can help keep everyone pointed in the same direction.
