The doctor:fix slash-command shorthand has been removed. Use /doctor instead — it now performs the same comprehensive checks and applies fixes after confirmation.

The old /doctor description ("Diagnose and verify your Claude Code installation and settings") has been replaced. The command is now a full repair tool, not a passive display.

References to "run /doctor" in MCP error messages have been replaced with "run claude doctor" (for settings/install issues) or "run /mcp" / "run /plugin" for server-specific problems.
