Next.js Bans 'Generated with Claude Code' Commit Footers, Part of 784 Prohibition Rules Across the 100 Most-Starred Repos

Someone read the AGENTS.md files of GitHub's 100 most-starred repositories and found vercel/next.js explicitly instructing agents not to add 'Generated with Claude Code' or co-author footers to commits or PRs. Across the corpus they counted 784 explicit don't-rules, including Bun forbidding direct `bun test` invocation, hugo's 'don't write a novel', and neovim's file consisting entirely of one AI-disclosure rule. The pattern the author names is that these files are scar tissue, every rule marks a mistake an agent already made in that repo, which makes the corpus a cheap source of failure modes to preempt in your own config.
