dsh-effort-router: A DeepSeek Harness Plugin for Automatically Switching Models Based on Difficulty

`dsh-effort-router` is a plugin for DeepSeek Harness (DSH) designed to address the pain points of invoking expensive models for simple tasks and underserving complex tasks with inexpensive models. Through an automatic routing mechanism, it switches to the appropriate model, thinking intensity, and vision tier before a request based on the difficulty of the text content. The plugin supports capabilities such as zero-token rule-based evaluation, gray-area handling, seat synchronization, and HTTP API. During installation, it must be added via a tarball path; after use, the Host must be restarted, while the Client only needs to be refreshed.
