Names in this entry
slash /doctor Skill .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.mdskills 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 Run /doctor prompt-audit to have Claude audit your CLAUDE.md files, skills, and other configuration for outdated or conflicting instructions instead of running the checkup.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
Anthropic's note
Upstream's own release notes for v2.1.210 name something this entry names, so the two are probably about the same change. Probably: the pairing is made on a shared name rather than on the words around it.
