Anthropic rebuilds Claude Code Projects for parallel agents

Anthropic rebuilds Claude Code Projects for parallel agents

3 Key Points

  1. What happened

    Anthropic rebuilt the Projects feature in Claude Code. A coordinator splits a described goal across parallel "threads", each a cloud session that can open pull requests, run tests, and share memory.

  2. Why it matters

    Threads can act on a goal at once, and a shared memory library collects uploaded files and results.

  3. What to watch

    The beta is limited to select Pro and Max subscribers on cloud sessions; wider access and local execution are still to come. Watch whether token usage rises as agents run more.

WHO IT HITSSoftware developers and engineering teams using Claude Code will see work split across parallel sessions they track from desktop or mobile. The change may shift how much control those teams have over token consumption.

Context & Analysis

Anthropic has moved Claude Code further from a single assistant that answers one prompt at a time. The rebuilt Projects feature now has a coordinator split a stated goal across parallel threads, each running as its own cloud session that can open pull requests and run tests. A shared memory builds across those threads over time, and a library collects uploaded files and results.

That design fits alongside Anthropic's recent decision to make autopilot mode the default in Claude Code, where the company claimed it outperformed human developers on safety tasks. The company's pitch is that more autonomous agents likely mean more burned tokens, and control over how many tokens get burned shifts from users to the company selling them — like letting gas companies control the throttle in your car.

The beta's reach is the immediate test: it is limited to select Pro and Max subscribers using cloud sessions, with Team and Enterprise access later and local execution coming soon. Whether the parallel setup actually delivers on a full goal, rather than just running more sessions at once, is likely to determine how quickly that wider access arrives.

FAQ
Who can use the new Projects beta in Claude Code?
It is open to select Pro and Max subscribers using cloud sessions in Claude Code. Team and Enterprise access comes later, and local execution is coming soon.
What can each parallel thread do?
Each thread runs as its own cloud session, can open pull requests and run tests, and shares a common memory with the other threads. Progress is trackable in the main chat or per thread, including on mobile.
How does this fit with Anthropic's other Claude Code changes?
Anthropic recently made autopilot mode the default in Claude Code and claimed it outperformed human developers on safety tasks. The update is another step toward code automation.
