Anthropic Redesigns Claude Code With Parallel Sessions and Routines

Claude Code's desktop interface received its most substantial redesign since the product launched. Anthropic shipped an updated app built around one concrete change: running multiple agent sessions simultaneously from a single window, orchestrated through a new persistent sidebar.

That sidebar does more than list open sessions. Engineers can filter by status, project, or environment, and group sessions by project to maintain visual coherence across parallel workstreams. A keyboard shortcut, Command + semicolon, opens a side chat branched off an active task, which means tangential questions can be handled without feeding extra context back into the main agent thread.

The development environment

The redesign also moves significant developer tooling into the app directly. There is now an integrated terminal for running tests and builds, an in-app file editor for targeted edits, and a rebuilt diff viewer aimed at large changesets. As MacRumors reports, the preview pane now renders HTML files, PDFs, and local app servers within the same interface, and all panes are drag-and-drop repositionable.

Three view modes give users control over how much of Claude's internal tool-call activity is surfaced: Verbose, Normal, and Summary. Agentic sessions generate substantial scaffolding during execution, and exposing all of it by default creates noise for users focused on results rather than process. Plugin support in the desktop version now matches the CLI, with SSH sessions supported on both Mac and Linux, according to 9to5Mac. The update reaches Pro, Max, Team, and Enterprise plan holders.

Routines: async automation without local infrastructure

Alongside the redesign, Anthropic introduced Routines, an automation layer that runs independently of any open session. A routine packages a prompt, a repository, and relevant connectors into a single configuration unit that can execute on a cron schedule, fire from an API call, or trigger on a GitHub event such as a pull request opening.

The infrastructure model is the key detail: Routines run on Claude Code's web infrastructure, not on the local machine. 9to5Mac notes this means a Mac does not need to be online for a scheduled task to complete. For teams managing automated review cycles and deployment pipelines, this offloads the orchestration that previously required configuring cron jobs, MCP servers, and supporting tooling outside the main development environment. Daily run caps scale by subscription tier, and Routines are in research preview for Pro, Max, Team, and Enterprise users with Claude Code on the web enabled.

What this signals

Anthropid is building toward an IDE-replacement model rather than a plugin model. The parallel sessions sidebar, integrated terminal, and async Routines each address a different layer of the friction between how engineers work (multiple concurrent tasks, background jobs, frequent context switching) and how most AI coding tools are currently structured: single-thread, foreground, session-bound.

The Routines execution model carries open questions. Running agent tasks on cloud infrastructure implies persistent compute, stored credentials, and ongoing repository access outside of active sessions. Anthropic has not yet publicly addressed the security surface area this creates, which is the question enterprise security teams will raise before approving broad deployment. MacRumors covers the full scope of the desktop changes in additional detail.

Launching Routines as a research preview rather than a stable release signals that Anthropic is collecting real-world usage data before committing to a locked API surface. Whether the cloud-run automation model accelerates adoption among engineering organizations, or whether security requirements create enough friction with enterprise buyers to slow rollout, will likely become clearer over the next few quarters.

FAQ

What are Claude Code Routines?
Routines are cloud-run automations that bundle a prompt, a repository, and connectors into a reusable configuration. They execute on Anthropic's infrastructure on a cron schedule, via API call, or in response to GitHub events, with no local machine required during execution.

How does the parallel sessions feature work in the Claude Code desktop app?
A new sidebar lists all active and recent sessions, filterable by status, project, or environment. The Command + semicolon shortcut opens a side chat tied to a running task without affecting that session's context window.

Which subscription plans include access to the redesigned app and Routines?
Both the desktop redesign and Routines are available to Claude Code users on Pro, Max, Team, and Enterprise plans. Routines require Claude Code on the web to be enabled and are currently in research preview.

Can Claude Code run automations when my computer is offline?
Yes. Routines execute on Anthropic's web infrastructure, so scheduled tasks and event-triggered workflows run regardless of whether the local app is open.
