Claude Code now reads AGENTS.md if there is no Claude.md
A changelog entry for Claude Code, surfaced on Hacker News, states that Claude Code now reads AGENTS.md if there is no Claude.md. The behavior described is a fallback: the AGENTS.md file is consulted only in the absence of a Claude.md file. The source excerpt does not specify search paths, precedence between multiple files, configuration flags, or a version number for the change. The entry is limited to that single behavioral statement. It does not describe how AGENTS.md content is parsed, whether nested directories are scanned, or whether the fallback applies across all Claude Code surfaces. No release date, model identifier, or benchmark figure accompanies the note in the provided text. The practical effect stated by the source is that a project containing AGENTS.md but no Claude.md will have that file read by Claude Code.
Developers who keep project instructions in AGENTS.md can have Claude Code read that file without creating a separate Claude.md.
