|  |  | I have the automatic "co-authored by" Claude signature turned off for my commits via the config setting. PSA: They've introduced a new "Claude-Session: https://claude.ai/code/session_xyz" line that's appended to the commit now though, on by default. Annoying, feels scummy (of all things, ironic I know) |
