If you've been running Claude Code for a while, your workspace configuration has probably accumulated some cruft. Skills you installed and forgot. MCP servers you added for one project. A CLAUDE.md file that's grown into a multi-page manifesto. The `/checkup` command — also known as `/doctor`, the underlying alias — was added in v2.1.205 to address exactly this. It's an interactive workspace audit that can find problems and, with your confirmation, fix them. Here's how to use it effectively. ## What `/checkup` Actually Does This is the important part before you run it: `/checkup` isn't just a diagnostic. Starting with v2.1.205, it moved from a read-only report to an interactive tool that proposes and can apply fixes. Each category of issue is presented separately, and you confirm or decline each proposed change before it's applied. The audit categories, per the official Claude Code documentation: - **Installation health** — Checks the Claude Code installation itself for issues - **Unused skills, MCP servers, and plugins** — Identifies items that are installed but not contributing meaningfully relative to their context cost - **CLAUDE.md deduplication** — Compares local `CLAUDE.md` files against versions that are checked into source control, flagging content that's redundant - **CLAUDE.md trimming** — Proposes removing content that Claude could derive from your codebase (imports, file structure that's already visible) - **Slow hooks** — Identifies hooks in your configuration that are adding latency to your workflow - **Auto mode** — Can enable auto mode if it's not already on - **Common read-only commands** — Can pre-approve commands that are read-only and safe, reducing confirmation prompts - **Claude version** — Updates Claude to the latest available version ## Running `/checkup` To run it, open a Claude Code session and type: ``` /checkup ``` Alternatively, the original command name also works: ``` /doctor ``` Both are aliases for the same functionality. Claude will begin the audit and present findings interactively. For each finding, you'll see what it detected and what action it's proposing. You then confirm or skip each change. **Important:** `/checkup` requires an active Claude Code session — it's a slash command within Claude Code, not a standalone CLI command you run in a terminal. ## What to Accept and What to Skip The audit is interactive by design, because not every proposed change is right for every workflow. Here's how to think through the main categories: **Unused skills and MCPs** — Accept removals for anything you don't recognize or haven't used recently. Context window space is finite; loading skills you don't use costs tokens every session. That said, if you have a skill installed for occasional use (say, a deployment tool you only use monthly), you can skip its removal and reinstall when needed. **CLAUDE.md deduplication** — Usually safe to accept. If a rule is already in your committed CLAUDE.md, having it duplicated locally adds noise without benefit. **CLAUDE.md trimming** — Be more careful here. Claude's proposal is based on what it believes it can derive from your codebase. Review the specific content being proposed for removal before accepting. If a rule captures intent or context that isn't obvious from code structure, keep it. **Slow hooks** — Accept disabling of hooks you don't actively rely on. If you use a hook for something important and it's slow, that's a cue to optimize it rather than disable it — but `/checkup` is still useful for surfacing which hooks are the culprits. **Auto mode and pre-approved commands** — These are convenience features. Auto mode reduces the number of manual confirmations. Pre-approved read-only commands (like `ls`, `cat`, `git status`) eliminate friction for safe operations. Accept if that aligns with how you work. ## When to Run It There's no hard rule, but `/checkup` is especially worth running when: - You've installed several new skills or MCPs recently and haven't audited what's actually running - Your session startup feels slow (slow hooks are often the culprit) - Your CLAUDE.md has grown to more than a page or two and you haven't reviewed it in a while - You've just updated Claude Code and want to make sure your setup is aligned with the current version For teams, `/checkup` is a useful post-onboarding step — new setups often accumulate exploratory installations that don't make it into the permanent workflow. ## What `/checkup` Doesn't Do Worth knowing the limits: `/checkup` audits your Claude Code workspace configuration. It doesn't touch your project files, git history, or any code. It won't delete files you've created. All its proposed changes are to Claude Code configuration — skills, MCPs, CLAUDE.md, hooks, and settings. It also won't make changes without confirmation. If you run `/checkup` and decline all proposals, your setup is unchanged. You can always run it again. ## Availability `/checkup` (and its `/doctor` alias) is available in Claude Code v2.1.205 and later. The interactive mode — where it proposes and can apply fixes — was specifically introduced in v2.1.205; earlier versions had a read-only diagnostic report. Update Claude Code before running if you're not sure which version you're on: ``` /checkup ``` The audit itself will report whether Claude is up to date as one of its checks, so running it on an older version will surface the update recommendation. --- ## Sources 1.
