/chrome in Claude Code: let Claude work in your Chrome session

Claude Code spots the extension and offers to use your Chrome from now on: your tabs, your cookies, your open sessions. What that yes actually allows depends on a setting you configured for something else entirely.

Claude Code diff panel: stop asking what changed and watch it live

In a wide enough terminal, /diff no longer takes over the prompt: it docks beside the conversation and refreshes on every edit. And what you select in it goes with your next question.

#190

claude plugin validate: catch what breaks your plugin before anyone installs it

One command reads your plugin.json, your skills, your agents and your hooks, and tells you which lines Claude Code will ignore at load time. What it stays quiet about matters just as much.

#189

Claude Code worktrees on Desktop: every session leaves a full copy of your repo on disk

Desktop creates a worktree per session without being asked, and they stay there. There is a panel that tells you how much space they take, and a switch that stops it happening again.
