What problem does it solve? Running parallel AI coding sessions on the same codebase often leads to conflicting edits, duplicated work, and no visibility into what each session is doing. This Skill provides the coordination patterns to run a lead session plus multiple teammate sessions safely on one repository. ## Core Features & Use Cases - Team Coordination: Set up a lead session that delegates to 2-5 teammate sessions sharing a task list, mailbox messaging, and file-lock claiming to prevent edit conflicts. - Task Decomposition Guidance: Break work into non-overlapping, independently verifiable tasks with declared dependencies so teammates pick up unblocked work automatically. - Plan Approval & Delegate Mode: Require teammates to submit plans for lead review before implementing, and use Shift+Tab delegate mode so the lead coordinates without editing code. - Use Case: You need to add rate limiting across middleware, Redis config, tests, and docs. Spin up two teammates, decompose into four tasks with dependencies, approve their plans, and let them implement in parallel while you review. ## Quick Start Enable the experimental flag and ask Claude to coordinate a team of sessions to implement a cross-layer feature with decomposed tasks and plan approval.
