summary: 'We''re adding support for AGENTS.md to Claude Code. Starting today in version 2.1.277, if there is no CLAUDE.md in a folder, Claude will check for and use AGENTS.md. AGENTS.md support is built off of Claude Code mods, our upcoming way to customize the Claude Code harness. This is a built-in mod, but you’ll be able to build custom versions of project instructions yourself as you’d like too. You can see the source for the mod here! — Thariq Shihipar, there are more mods here Tags: thariq-shihipar, coding-agents, anthropic, claude-code, generative-ai, ai, llms'
