/doctor

slash never mined documented JSON

A Claude Code slash command, read out of the shipped bundle. No mined inventory carries it: everything below comes from what this site has written about it.

Skill. Run a setup checkup that diagnoses issues and can fix them. Checks installation health, including duplicate or leftover installs, PATH problems, and unparseable settings files. Finds unused skills, MCP servers, and plugins versus their context cost, flags slow hooks, and checks for a newer version on your release channel. Deduplicates local CLAUDE.md files against checked-in ones, trims checked-in CLAUDE.md files by cutting content Claude could derive from the codebase, and migrates the always-loaded guidance that remains into skills and nested CLAUDE.md files that load on demand. Also offers to make auto mode your default and to pre-approve frequently denied read-only commands. Reports findings first and asks for confirmation before changing anything. From the terminal, claude doctor prints read-only installation diagnostics without starting a session. Alias: /checkup. Run /doctor prompt-audit to have Claude audit your CLAUDE.md files, skills, and other configuration for outdated or conflicting instructions instead of running the checkup. The prompt-audit subcommand requires Claude Code v2.1.283 or later. The CLAUDE.md trim check requires Claude Code v2.1.206 or later. Before v2.1.205, /doctor opened a read-only diagnostics screen and pressing f sent the report to Claude

The earliest release whose published evidence quoted /doctor was v2.1.182, 18 Jun 2026. That is the oldest release this project wrote about it, so it is a floor on the name's age and not the release that introduced it. It is not a presence reading: which builds carried the name is the table below.

The miner has never read a build containing this name. It is here because a changelog entry of ours names it, which is evidence that it existed and not evidence of which releases carried it. The inventory starts at v2.1.138 and everything older than that was never mined.

Read out of the published npm bundle release by release, and out of Anthropic's own documentation as this site captured it. Nothing on this page is a description anybody here wrote about what the slash command does. All slash commands.
