Claude Code was showing agents a stale git status

Claude Code kept showing agents a stale git status after every compaction, reusing the snapshot from session start no matter how long the run went. In a long autonomous run that compacts several times, the agent reasons about a working tree that no longer exists, including files it already committed.

Anthropic fixed it in Claude Code 2.1.269, which now re-reads git status at compaction time instead of reusing the old snapshot. The model never saw its own commit happen, so a file it had checked in still looked untouched, and it reopened it to edit again.

I've watched this exact failure happen in my own long runs, and I blamed it on the model losing track of state. It wasn't losing track. It was working from a snapshot that predated its commits.

The changelog doesn't say how far back the bug goes or how many releases carried it. That leaves open how much of the 'agent forgot what it did' behavior in past sessions traces to this specific bug.
