DeepSeek Redefines Plugins: Harness Makes Everything Pluggable
APPSO · wechat · 2026-08-19
DeepSeek's Harness concept and plugin practice expand the traditional notion of plugins from peripheral features to the core of Agent infrastructure. Via the Cordis meta-framework, DSH achieves "everything is a plugin," allowing sessions, sandboxes, file systems, and even the main loop to be replaced and composed. Using the Seam structure to decouple interfaces, providers, and consumers, developers can reconfigure system behavior via YAML rather than code. The article contrasts Chrome plugins (add-ons) with DSH plugins (modular office components) and discusses the trade-offs between flexibility and stability, offering a new paradigm for building customizable Agent workflows.
