dsh-reasoning

English | 简体中文

A community DeepSeek Harness Web plugin for configuring model reasoning effort. It adds a settings card for assigning reasoning levels to one or more models and keeps model selection in the DSH conversation composer. The model popup opens side-by-side, so the Model and Reasoning rows remain visible while their options are being browsed.

This is an independent community plugin. It is not an official DeepSeek product and does not imply DeepSeek endorsement.

Highlights

• Per-model configuration — Configure reasoning levels independently for every model exposed by each provider.
• Bulk editing — Select several models at once, then apply standard levels (Off, Minimal, Low, Medium, High, Extra high, Max) in one step.
• Custom wire values — Add provider-specific levels with id when the identifier is also the wire value, or id=wireValue when it differs.
• Native composer integration — The plugin uses DSH's model directory and selection APIs instead of adding a second composer control.
• Side-opening model menu — Browse models and reasoning levels without losing the current selection context.
• Provider-aware persistence — Changes are written to llm-pi-ai.providers.<provider>.models[].reasoningEfforts, allowing DSH and the provider integration to validate and send the configured value.
• No fabricated defaults — Models without configured levels show no fake reasoning menu.

Install

Install the GitHub source package into the DSH Web profile:

dsh plugin --profile web add github:LanQin996/dsh-reasoning#main

Restart the DSH Web profile after installation so the Host and Client plugin graph is rebuilt.

To install a local checkout while developing:

git clone https://github.com/LanQin996/dsh-reasoning.git
dsh plugin --profile web add file:./dsh-reasoning

To remove the plugin:

dsh plugin --profile web remove dsh-plugin-reasoning-effort

Use

After restarting DSH Web, open the model selector in the conversation composer. The popup keeps the current Model and Reasoning rows on the left; choose the corresponding list on the right. The Reasoning row is shown only when the selected model has configured levels.

Settings

Open:

Settings -> Plugins -> Plugin configuration -> Reasoning Effort

Expand the card, select one or more models, and configure the levels to expose:

• Standard levels — Toggle the levels supported by the selected models.
• Custom levels — Enter comma-separated values such as balanced, thorough=high_reasoning.
• Apply — Save the draft levels for all selected models.

The card reads the existing llm-pi-ai provider settings. It does not create a fallback menu for a model whose reasoningEfforts object is empty or missing.

Local patch loading

For a checkout that should be loaded directly by a DSH installation, use the included cordis.patch.yml:

dsh web --patch C:/path/to/dsh-reasoning/cordis.patch.yml

The patch inserts the plugin with the id dsh-reasoning-effort.

Development

The repository contains the Host entrypoint and the browser-side client in src/index.js and src/client.js. The package currently has no build or test script; changes can be checked with Node's syntax validator:

node --check src/index.js
node --check src/client.js

The client expects the DSH Web runtime and peer packages declared in package.json. When testing locally, load it through the patch command above inside a DSH installation that provides those packages.

Scope and privacy

The plugin does not add a telemetry client, credential flow, or background network service. It reads the active DSH model directory and llm-pi-ai settings, then persists only the configured reasoningEfforts values through the DSH settings store.
