Claude Projects: Delegate Work to Parallel Code Sessions

Claude Projects is becoming a coordinator for parallel Claude Code cloud sessions: learn how to connect repositories, set project instructions, choose thread models and effort, and manage local-only work. We also cover practical limits and cost traps, including paused sandboxes, pull-request follow-up threads, and usage-limit resumption, plus smaller fixes in 2.1.301 and 2.1.302.
