Introduction to the DeepSeek Harness Automatic Model Routing Plugin

The `dsh-auto-model-router` plugin addresses the inconvenience of manually switching model tiers in DeepSeek Harness (DSH). Using session state machines, keyword matching, and a manual-priority mechanism, it automatically routes requests to the Chat (cost-saving) or Work (deep reasoning) tier based on context. The plugin supports automatic switching, cooldown limits, and logging of first-round selections, significantly improving the user experience. It becomes active after re-entering DSH following installation, although a few known limitations remain in scenarios such as IM first-round popups.

dsh-agent-dispatch: Custom Agents and Automatic Routing Orchestration

`dsh-agent-dispatch` is a plugin for DeepSeek Harness, designed to handle multi-domain tasks, automatically route requests, and orchestrate complex pipelines through custom agents and squad templates. It provides a floating-ball UI and supports model priority switching, context reuse, and dependency-driven task execution. Users define agent trigger domains, personas, and squad steps via JSON files, while using tool functions to delegate tasks, ask follow-ups, or import skills.

DeepSeek Harness Dual-Model Automatic Routing Plugin: Low-Cost Direct Access and Escape Learning Loop

The DeepSeek Harness (DSH) dual-model auto-routing plugin aims to resolve the trade-off between cost and quality in development. Utilizing the "everything is a plugin" architecture and a six-criteria routing decision process, it automatically switches between the low-cost Flash model and the high-cost Pro model, and automatically downgrades if an upgrade fails. The plugin introduces an "Escaping Learning Closed-Loop" mechanism, allowing users to flag incorrect answers to update the fingerprint log, ensuring that similar requests trigger a forced upgrade next time to avoid repeated mistakes. The tool supports persistent storage and interoperability, enabling developers to use tools such as dual_model_run across all sessions after installation to achieve intelligent model scheduling.

dsh-agent-preset-router: Automatic Mode Routing Plugin for DeepSeek Harness

The `dsh-agent-preset-router` plugin provides an “automatic mode” for the DeepSeek Harness (DSH) Web Profile, addressing the hassle of manually switching between multiple presets. It uses a Flash model to anticipate user requests and automatically routes them to the most appropriate preset for execution, without requiring further confirmation. It supports displaying a decision info bar in the input box, and if classification fails, it automatically falls back to the default preset. Installation is simple and ready to use out of the box. Note that routing only applies to the first message of a conversation and cannot be canceled or retried midway. The plugin is open source and flexible, making it well suited for automated routing needs.
