> And many other comment sins.

I find that it helps Claude when it's updating that code again (it's a kind of out-of-session memory). A few times it's come across a past decision I gave it, and notified or asked me to clarify where an update would be conflicting. I'm not reading the code but I sure know when those "sins" help to prevent a regression or otherwise undesired behavioral change.

Claude-written code is quite easy to spot - because it has this particular style of overly verbose "walls of text" comments, that 1. repeat verbatim what the code just below does, 2. include "list of things" that quickly go stale, 3. talk about "how things used to be before we changed it here" (useless to anyone reading the code now), 4. "talk to reviewer" in comments. And many other comment sins.

"quite easy to spot" this style in what sense? To a human? To an LLM? To a deterministic code scanner you wrote by hand yourself, per Codeberg policy?

That doesn't really answer the question of how they're going to detect it at scale. Ban repositories with long comments?

As other have mentioned, and I'm the same. Leaving "Co-Authored by:" feels like open disclosure of how the project was created.

That way if a consumer does not want to use LLM generated/assisted software, it's easy for them to do that without having to search around in the codebase for "AI Tells".

Removing those would feel like I was mis-representing my coding abilities (LLMs are better at most coding than I am) :)

I expressly leave them there for transparency and potential future analysis. I'm even working on a coauthor attribution format for work done with Pi agent, as well as when there are multiple models collaborating. If Codeberg wants to gatekeep on AI-generated code, I'll leave them to their tiny niche.

I feel it's a faux pas to pass off work entirely or partially done with AI as your own. I make sure I leave those lines in specifically for that reason.

honesty?

AGENTS.MD and CLAUDE.MD also provide easy detection avenues. Trivial measures will probably catch 70-80% or more. You don't need a 100% enforcement rate for a rule to exist, indeed there are basically no rules anywhere in the world that achieve that.
