Eh, I see every 4th project post in open source communities being a cool looking project with no Claude contributed, no AI disclaimer, no agents.md, however when you look at the user's commit history on the git service, it is

• 10-20 contributions (mostly issues) before 2025
• maybe a couple readme or documentation commits in total
• mid to late 2025, user starts committing 500-5k lines per day, every 3-5 days, evolving from large commits to broken up 100 commits today (following the 2025-2026 timeline where AI started doing the same)
• exact same commit structure that AI uses, and filled with jargon
• no comments at all on the post, or few comments but never responding to anything technical about how the program works.

Probably some confirmation bias going on on both our sides.
