Description: 

Generated by Claude Code 2.1.319 (Claude Opus 5.5)

core/CLAUDE.md has been removed. It contained one line, @AGENTS.md, which imported core/AGENTS.md.

Claude Code 2.1.277 and later loads AGENTS.md when a directory and its parents have no CLAUDE.md or CLAUDE.local.md. The "Project instructions" setting in /config controls this:

  • claude-md-or-agents-md (default): loads core/AGENTS.md.
  • claude-md-and-agents-md: loads core/AGENTS.md and any CLAUDE.md.
  • claude-md: does not load core/AGENTS.md.
  • managed-only: does not load core/AGENTS.md.

Claude Code does not load core/AGENTS.md in these cases:

  • Versions before 2.1.277.
  • The built-in AGENTS.md plugin is disabled.
  • Some first sessions after upgrading from 2.1.276 or earlier.
  • A personal CLAUDE.local.md exists in core/ or above it.
