Ultraplan cloud planning, the Monitor tool with self-pacing /loop, /team-onboarding for packaging your setup, and /autofix-pr from your terminal.
Kick off plan mode in the cloud from your terminal, then review the result in your browser. Claude drafts the plan in a Claude Code on the web session while your terminal stays free; when it's ready you comment on individual sections, ask for revisions, and choose to execute remotely or send it back to your CLI. As of v2.1.101 the first run auto-creates a default cloud environment, so there's no web setup step before you can try it.
A new built-in tool that spawns a background watcher and streams its events into the conversation: each event lands as a new transcript message that Claude reacts to immediately. Tail a training run, babysit a PR's CI, or auto-fix a dev server crash the moment it happens, all without a Bash sleep loop holding the turn open.
PR auto-fix landed on the web in Week 13. Now you can turn it on without leaving your terminal: /autofix-pr infers the open PR for your current branch and enables auto-fix for it on Claude Code on the web in one step. Push your branch, run the command, walk away; Claude watches CI and review comments and pushes fixes until it's green.
Generates a teammate ramp-up guide from your local Claude Code usage. Run it in a project you know well and hand the output to a new teammate so they can replay your setup instead of starting from defaults.
Run it from a project you've spent real time in:
