dsh-ui-skin-switcher: DeepSeek Harness Model and Reasoning Effort Switcher

When using the DeepSeek Harness (DSH) Web interface, frequently switching models and adjusting the reasoning (thinking) intensity are common needs. This plugin integrates that workflow into a compact “seat” next to the input box, providing a Claude Desktop-style interaction that can replace or supplement the original model selection panel.

What It Is¶

dsh-ui-skin-switcher is a plugin built for the DSH Web interface. It registers the conversation.input.model plugin slot and renders a model and reasoning-intensity switcher next to the input box. It follows the same channel as the official first-party model selector: it reads the model directories via ctx.modelDirectories, then submits selections through the same selection API, ensuring that switching results remain consistent with the /model panel.

Core Features¶

• Model switching: Click the button to expand the list. The list is grouped by provider, and the current model is marked with a check.
• Reasoning intensity slider: Supports both clicking and dragging. The slider is displayed only for models that declare reasoningEfforts.
• Maximum-intensity dot-matrix animation: When the highest level is reached, a dot-matrix animation appears inside the track, and the slider is accompanied by a glow effect.
• Per-model memory: Remembers the last selected reasoning intensity for each model, so it can be restored quickly after switching models.
• Theme adaptation: Colors are bound to DSH theme variables, supporting light and dark themes as well as transparent background skins.

Installation and Enabling¶

Install it using the official CLI:

dsh plugin --profile web add @domitor-syh/dsh-ui-skin-switcher

After installation is complete, restart dsh web. The switcher button will then appear next to the input box.

Usage¶

1. Switch models: Click the button next to the input box and select a model from the list. The list is grouped by provider, and the current model is marked with a check.
2. Adjust intensity: For models that declare reasoningEfforts, a reasoning-intensity button appears to the right of the model. After clicking it, drag the slider or click on the track to switch between levels.

Notes¶

• Version requirement: Only DSH 0.1.5 and later are supported.
• Configuration requirement: Reasoning intensity is defined as a vendor-private wire-level value for each level. Incorrect values may cause requests to fail silently, so the plugin does not provide a unified level configuration. You must manually modify the settings.yaml file in the DSH home directory.
• Display logic: The slider is displayed only for models that declare reasoningEfforts. If the current model does not declare this capability, the intensity-adjustment feature is not shown.
