Projects coordinate work across threads
Anthropic says a Claude Code project can scope a request, delegate work across parallel threads, review their outputs, and assemble the result. Users can guide progress in the project chat or inspect individual threads. Each thread runs as a Claude Code cloud session on its own branch and copy of the repository.
Projects also have shared memory and a library for files and artifacts. Anthropic says threads can split delegated work further using subagents, loops, and workflows. Threads run in the cloud; running them on a user's machine was described as coming soon.
September 17 beta rollout announcement and usage limits
In its September 17 announcement, Anthropic said the beta was then available to select Claude Pro and Max subscribers who use cloud sessions in Claude Code and have no existing projects on web or desktop. It said access would expand over the coming week to more Claude Code users on those plans, with updated projects across Claude, Team, and Enterprise plans to come after that. The announcement does not establish the rollout's current status.
Anthropic warned that projects can reach usage limits faster because they can run several threads at once, each a full Claude Code session. It said users can check project-specific usage and select the model and effort levels used by the coordinator chat and worker threads.
