Unclear It is not clear what the new block of lines actually lists.

What

/doctor is the command that checks your Claude Code setup and reports problems. Its report now prints a new block of lines before the "Environment variables" section. Each line comes in a pair with an indented detail line under it. Previously the report went straight from its earlier checks to the environment variable warnings.

Why

Running /doctor now gives you more diagnostic information before the environment variable checks.

Since it was published

The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.

Confirmed since Anthropic's documentation has since written up /doctor, on Extend Claude with skills. ### Check your setup with `/doctor` skills see the edit
