The raw session noise — repeated clarifications, trial-and-error prompting, hallucinated APIs — probably isn't worth preserving. But AI sessions contain one category of signal that almost never makes it into code or commit messages: the counterfactual space — what approaches were tried and rejected, which constraints emerged mid-session, why the chosen implementation looks the way it does.

That's what architectural decision records (ADRs) are designed to capture, and it's where the workflow naturally lands. Not committing the full transcript, but having the agent synthesize a brief ADR at the close of each session: here's what was attempted, what was discarded and why, what the resulting code assumes. Future maintainers — human or AI — need exactly that, and it's compact enough that git handles it fine.
