I tried maintaining chat hostory and summary in a 'changes' dir in the repo. Claude creates a md file before commiting (timestamp.md, commit hash doesn't work as filename because rebase/squash).

I had to stop doing this because it greatly slowed down and confuse the model, when it did a repo search and found results in some old md files. Plus token usage went through the roof. So keeping changes in the open like that in the repo doesn't work.

Not sure how tfa works, but hopefully the model doesn't see that data.
