Claude Code’s new /checkup command cleans up context and settings

Claude Code has a new /checkup command that walks your project and runs 7 maintenance steps. The main one: clearing out unused skills, MCP servers, and plugins to save context.
From there it diffs your local CLAUDE.md against the repo version and strips duplicates, splits a bloated root CLAUDE.md into nested files and skills, and disables slow hooks. The rest is housekeeping: updating Claude Code to the latest version, turning on auto mode by default, and pre-approving read-only commands you keep rejecting.
/checkup asks for confirmation before making any changes. It joins the recently shipped /rewind and /usage.
