Claude Session URL appended to commit messages and PR descriptions by default

Presumably quietly added default-on because everyone had turned attribution off.

Again, if you challenge it “It came from my harness instructions” and obviously telling it not to in memory is about as successful as… any other instruction in memory, about 60% of the time.

I really hate this attribution nonsense ...

On one hand I guess it is fine to automatically tag that the commit was AI-generated. On the other hand, this will happen even if you audit every line and add your own changes too, which means the attribution is misleading.

This is probably a controversial take, but I love this. Back in the early days of claude code I had to write a script (well, claude wrote it) to pull out the session id and append it to every commit. It's a lifesaver when you are trying to debug an old commit to pull up the chat session that actually wrote it.

Anthropic is right here. You need to clearly define what commits are AI authored or you are conspiring to commit copyfraud.

AI does not enjoy copyright protection. Pretending you created something written by AI is copyfraud.

Just because it's not in the title and most people won't be scrolling all the way down: its only enabled for web and Remote Control sessions, per a maintainer.
