dsh-effort-slider is a native plugin built exclusively for DeepSeek Harness (DSH), that adds a Claude Code-style stepless reasoning effort slider to the DSH interface. Users can click the new Effort row in the official DSH model menu to bring up the slider panel, which supports continuous dragging from 0 to 100, snaps to the nearest level on release, and includes a WebGL-animated fire trail that follows the slider thumb. It adds working reasoning effort control to any third-party model or provider that does not natively support it, integrating seamlessly with DSH’s existing model menu structure.

After installing the plugin via DSH’s package manager, you just need to restart DSH to activate it. Once restarted, open the DSH model menu and click the added Effort row to pull up the slider panel. As you drag, your current effort level is updated in real time, and after you release the slider, the effort value stays color-coded on the menu row and the model trigger button above the composer. This plugin is ideal for DSH users who want fine-grained control over LLM reasoning effort and prefer the Claude Code-style slider interaction.

This plugin is released under the permissive BSD-3-Clause open source license. It does not read any user credentials or send any data over the network, only communicating with the local DSH instance. For development, you need pnpm to install dependencies, which include TypeScript 5 and React 18. After installing dependencies, run pnpm build to compile the plugin, and pnpm test to run the full test suite. One known conflict is with other DSH plugins that also intercept the Effort menu row, which will cause duplicate panels to appear, so you need to disable interception in one of the plugins.
