Autonomous Kanban Chain (D3)

Overview

The D3 autonomous kanban chain is a sequential, dependency-driven workflow for multi-agent coordination. Each task represents a discrete unit of work that must be completed before dependent tasks can begin. This document defines the chain structure, provider restrictions, reporting requirements, and the no-parallel rule.

Chain Structure

Sequential Execution

• Tasks are executed sequentially in dependency order
• A task with parents remains in todo status until ALL parents reach done
• Once all parents are done, the task auto-promotes to ready and becomes eligible for dispatch
• The dispatcher picks the highest-priority ready task for each profile
