Next.js Bans AI-Generated Commit Footers

·2026.08.22 00:01

Key point

An analysis of AGENTS.md files from the top 100 GitHub repositories revealed that Next.js explicitly prohibits adding AI-generated commit footers.

Details

An analysis of AGENTS.md files from the 100 most-starred repositories on GitHub revealed specific restriction rules regarding AI agent usage.

The Vercel Next.js project explicitly states not to add "Generated with Claude Code" or co-author footers to commits or PRs.

These rules serve as "scars" to prevent mistakes previously made by AI agents. The 100 analyzed repositories contained a total of 784 explicit prohibition rules.

Key examples include:

  • Bun: Prohibits running bun test directly
  • Hugo: "Do not write novels" (to prevent unnecessary code generation)
  • Neovim: The entire file consists solely of AI-disclosure rules

Based on this analysis, a copy-paste-ready AGENTS.md template extracted from all repositories was also released.
