Claude Code Fully Open, Integrated with AGENTS.md

According to a report by Jinse Finance, Claude Code's core engineer Thariq posted on X, and the post garnered over a million views within an hour. Starting from version 2.1.277 released that day, if the project folder does not contain CLAUDE.md, Claude will automatically look for AGENTS.md to read. Developers have been waiting for this update for over a year. The GitHub repository's issue titled 'Please support AGENTS.md,' which has been open since August 2025, has accumulated over 5,200 likes and more than 300 comments, making it the highest-voted feature request in the entire Claude Code repository—four times higher than the second place.
