Deins architecture
A versioned harness below a collection of capabilities and host-specific adapters.
Foundation
DeepSeek Harness provides the plugin-based runtime. Deins adds product plugins for knowledge, workspaces, communities and authority integration. Keeping the foundation versioned supports upstream maintenance.
Portable does not mean identical
The shared capability can have a native Deins interface and a tool interface for another agent. MCP can expose capabilities outward; ACP can connect an external agent inward. Neither implies the complete Deins interface runs inside another host.
Protected foundations
Creator-built plugins must not be able to remove the authority boundary they operate under. Protected runtime ownership, signing and controlled activation remain architecture work.
