Claude Code on desktop now has a built-in browser. Claude can pull up docs, designs, or any other site, and read, click through, and interact with pages the same way it does with your local dev server previews. The browser is sandboxed and configurable: you choose whether browsing sessions persist, and safety classifiers review actions on external sites.
/doctor now diagnoses issues and can fix them, instead of printing a read-only report. It checks installation health, finds unused skills, MCP servers, and plugins versus their context cost, deduplicates local CLAUDE.md files against checked-in ones, proposes trimming CLAUDE.md content Claude could derive from the codebase, and flags slow hooks. It reports findings first and asks for confirmation before changing anything. /checkup is its alias.
