Overview
On September 17, 2026, Anthropic introduced a new experience for Claude projects, now available in beta in Claude Code. Managing multiple sessions across a build used to require you to divide the work, juggle handoffs, and stitch the results back together. Now in a Claude Code project, you describe what needs to get done and Claude manages the work.
Key features
-
A coordinator that directs threads
Projects have threads that do the work and a coordinator that directs them. Claude scopes the request, delegates the work, coordinates parallel threads, reviews the outputs, and assembles the finished result. You can follow progress in the main project chat or open any individual thread.
-
Each thread is a cloud session
Each thread is a Claude Code cloud session working on its own branch and copy of the repo. With repositories connected, a thread opens pull requests. Examples from the announcement include profiling each endpoint, testing optimizations, and opening PRs in parallel threads, and retiring deprecated API endpoints by migrating the callers, running the tests, and opening PRs.
-
Shared memory
Every thread now adds to and draws from a shared memory, reducing the need for complex prompt engineering.
-
A library for files and artifacts
Projects now include a library that collects the files you add and the artifacts produced by Claude, making it easier to find relevant materials and for new work to build on past efforts.
-
Adjustable check-ins
Claude also checks in and follows through on work. You can ask it to adjust how often it checks in, how frequently it starts new threads, or how detailed to make each update.
Notes
- Beta availability — Available to select Claude Pro and Max subscribers who use cloud sessions in Claude Code, expanding to more Claude Code users over the coming week. Pro and Max users without access can join the waitlist.
- Team and Enterprise later — Updated projects across all of Claude and Team and Enterprise plans come after that. No date was given.
- Usage limits — Projects can reach usage limits faster. You can check project-specific usage and select the model and effort levels used by the coordinator chat as well as the worker threads.
- Cloud only for now — Threads run in the cloud today; running on your machine alongside your local tools and code and behind your network is coming very soon.
