DSH Cluster Plugin: Orchestrating Multi-agent Information Flow in DeepSeek Harness

The DSH Cluster Plugin is a multi-agent collaboration plugin for DeepSeek Harness that defines agent nodes and directed edges via a visual canvas to enforce message flow constraints. Core features include: 1. Canvas Node Graph: Supports adding nodes, connecting unidirectional/bidirectional edges, and binding agents; 2. Agent Management: Supports single, multi, and any modes, with configurations automatically saved locally; 3. Information Flow Constraints: Defaults to rejecting undeclared message flows; `cluster_view` only displays self and downstream nodes to prevent information leakage. Additionally, it supports exporting and loading configurations, as well as mounting independent identity spaces (e.g., memory, skill files) for Agents. Users require a Node ≥ 22.19 environment and can install it via `dsh plugin`.
