CLAUDE_CODE_ADDITIONAL_DIRECTORIES_CLAUDE_MD

Updated October 23, 2026 by Alex Sorokoletov

CLAUDE_CODE_ADDITIONAL_DIRECTORIES_CLAUDE_MD is a Claude Code environment variable: Additional directories to scan for CLAUDE.md files (colon-separated). Removed between v2.1.307 and v2.1.309, so current releases ignore it. It is listed in the official reference.

How to set it

For one session, export it in the shell that starts Claude Code:

export CLAUDE_CODE_ADDITIONAL_DIRECTORIES_CLAUDE_MD=<value>
claude

To apply it to every session, add it to the env object of a settings file:

// ~/.claude/settings.json
{
  "env": {
    "CLAUDE_CODE_ADDITIONAL_DIRECTORIES_CLAUDE_MD": "<value>"
  }
}
