By the way, if you go to https://github.com/claude and "block this user", every Github repo you visit containing code written by Claude will actually have a warning sigil

[val@oc.todon.fr]

@Taffer @mcc It happens when people tell Claude Code to commit their changes and allow it to set --author or Co-Authored-By.
The @claude account itself doesn't seem to be doing anything.

[canine3625@mastodon.social]

@mcc made a mastodon account to tell you this fucking rules, thank you

[kstrlworks@techhub.social]

@mcc Consider the following as well:

https://github.com/cursoragent
https://github.com/gemini-code-assist

Copilot doesn't let you block it unfortunately.

[derekmceachern@infosec.exchange]

@mardor @micha @mcc thanks for this, I couldn't find it either

[norbertschuler@norden.social]

@mcc works pretty well. I have done an obvious test

[glyph@mastodon.social]

@mcc thank you for the suggestion, this has proven to be a real engine for interpersonal disappointment

[jkanev@fediscience.org]

@mcc Nice! Also, leave github and switch to #codeberg. (@Codeberg )

[nick@donotsta.re]

@mcc oh no

[emjonaitis@mathstodon.xyz]

@mcc interesting. I’m not sure about the sensitivity of this as a marker; when I go to a repository I use a lot, I don’t see this banner, but I do see a recently edited folder called .claude — am I misunderstanding when I assume that means some of the code has been written by this tool?

[mcc@mastodon.social]

@emjonaitis The marker appears whenever a git commit is created with the "co-authored-by" label. This is something claude can be configured to not create:

https://code.claude.com/docs/en/settings#:~:text=Claude%20Code%22%2C%20%22pr%22%3A%20%22%22%7D-,includecoauthoredby,-Deprecated%3A%20Use%20attribution

Moreover, one assumes that this only occurs when claude actually *performs the commit*. I would assume there are means of using claude where claude changes the code on disk and then the co-authored-by does not appear. Unfortunately, I don't know how to get an answer to that question without talking to a claude user

[mcc@mastodon.social]

@emjonaitis The .claude directory is, *as far as I know* (again, this is partially assumptions) configuration for claude to help it work with the codebase. Anyone who adds such a directory is essentially *inviting* claude commits. However technically they might not be using it to create code, they technically could be using it to answer questions about the codebase. Technically. One assumes this results in as much global warming as using it to write code however.

[kstrlworks@techhub.social]

@mcc @emjonaitis For context this flags people using agentic coding, i.e., having Claude code running on your machine, actively going through your folders and making changes. If they allow Claude to commit, it will do so under its own name unless disabled. This is the same with Cursor and Gemini.

The .claude folder in repos means they're using Claude to write the code; it's a per-project config file for the tool. It's similar to a .cursor file; it means it was used to write the code and is a better indicator than the co-authored commit.

@nick @mcc time to improve gcc.

If anyone needs a mentor on gcc, i can help.

[lanodan@queer.hacktivis.me]

@nick @mcc Also https://github.com/llvm/llvm-project/issues?q=involves%3A%40copilot

[lanodan@queer.hacktivis.me]

@pinskia @nick @mcc Sadly LLVM isn't just a compiler, see how it's a mesa dependency for example or tools like clang-format, lldb, …

[kevingranade@mastodon.gamedev.place]

@mcc @emjonaitis unless they are using it to poison the agents in question. I'm not poisoning a .claude directiory but I am poisoning a .github/copilot-instructions.md (we actually started getting some copilot-agent spam)
I do think I'd be a lot more hesitant to put an anti-agents node in the root directory since it would be more likely to be seen but not read, but also my software isn't a piece of infrastructure where people are looking at using it in that way.
