Anthropic is revamping its Claude Code desktop app under the “Epitaxy” codename, adding multi-panel views for Plans, Tasks, Diffs and support for multiple repositories. It also introduces a Coordinator Mode that lets Claude orchestrate parallel sub-agents and create custom agents in-app, mirroring OpenAI’s Codex agent workflow but running locally on the desktop.

• Anthropic's "Epitaxy" update overhauls Claude Code's desktop app with side-by-side Plans, Tasks, and Diffs panels, plus multi-repo support and in-app code preview.
• A new Coordinator Mode brings sub-agent orchestration (previously CLI-only) into the desktop UI, letting Claude delegate work across parallel sub-agents.
• This directly mirrors OpenAI's Codex "Magic TODO" parallel-agent workflow, but runs locally instead of in the cloud.
• Both companies are racing to ship these desktop updates as soon as next week, signaling a shift in competitive focus from model performance to workflow integration.

Ultraplan is a research-preview feature in Claude Code v2.1.91+ that drafts a plan for your codebase remotely. You launch it from the CLI, review and comment on the plan in a browser interface, then choose to have Claude implement it on the web or send it back to your local terminal for execution.

• Ultraplan (research preview, Claude Code v2.1.91+) drafts plans remotely in the cloud, freeing up your local terminal while it works.
• You can trigger it via "/ultraplan", typing "ultraplan" in a prompt, or opting into it after a local plan finishes.
• The web review interface lets you highlight text, leave inline comments, and use emoji reactions before approving.
• Once approved, you choose to execute the plan directly in the cloud or "teleport" it back to your local CLI session.
