dsh-wsl-mnt: Detect Slow Workspaces in WSL /mnt and Suggest Linux Paths

In the plugin ecosystem of DeepSeek Harness (DSH), the development experience under WSL is often limited by filesystem performance. When a workspace is mounted on /mnt/c (Windows NTFS), Git operations and file read/write speeds are often slow. DSH’s plugin-based architecture allows us to address this type of issue through extensions. This article introduces the dsh-wsl-mnt plugin, which uses the mnt_doctor tool to identify and handle these slow paths.

Plugin Introduction¶

dsh-wsl-mnt is a client plugin maintained by user 173787247. Its core value lies in resolving performance issues with cross-filesystem access in WSL environments. After installation, the plugin automatically detects path types when DSH processes a workspace, especially for projects located on slow /mnt partitions (such as /mnt/c formatted as NTFS), and provides clear prompts and migration recommendations.

Core Features¶

Slow path identification and classification: The tool can automatically identify and classify workspaces located on slow drives, in the Desktop directory, or in a .git directory.
NTFS performance warnings: It specifically flags projects located on /mnt/c and points out the performance bottlenecks of Git operations on the NTFS filesystem.
Path recommendations: When the above conditions are detected, it recommends that developers migrate their workspaces to native Linux paths under the user Home directory to achieve faster filesystem response times.

Installation and Enabling¶

Use the officially provided command to complete the installation. Make sure your DSH version meets the minimum requirements.

dsh plugin --profile web add github:173787247/dsh-wsl-mnt

Typical Usage¶

When a DSH agent enters a workspace mounted on /mnt/c, the plugin intervenes. It uses the mnt_doctor tool to analyze the current environment. If it finds that the workspace is on an NTFS partition or in a non-native Linux path such as the Desktop, it warns the user and recommends moving the project to a Linux Home path for continued development.

Applicable Scenarios and Notes¶

Applicable scenarios: Primarily intended for users developing with DSH in WSL environments, especially projects that require frequent Git operations.
Permissions and security: The plugin runs with the permissions of the current DSH process. You should review the source code and license before installation.
Configuration dependency: Configuration for the Cloud Flash model (deepseek-flash V4.1 Flash) must be manually set in ~/.dsh/settings.yaml or llm-deepseek. This plugin does not manage this configuration.
Version note: Regarding the version number, the README states 0.2.0, but the latest version verified in the compatibility matrix is 0.2.0-rc.2.

Conclusion¶

Through automated detection, this plugin helps developers avoid WSL filesystem performance pitfalls, thereby optimizing development efficiency. For more details, please see the GitHub repository.
