In the development practice of DeepSeek Harness (DSH), when agents need to handle structured data and write to databases, they often face the need to convert between JSON format and SQL statements. Manually writing conversion logic increases maintenance costs. DSH’s plugin-based design allows developers to address such issues through local extensions. Below is an introduction to a purely local JSON-to-SQL tool.

Plugin Positioning

dsh–to-sql is a DSH plugin maintained by developer uckkk, with core functionality of converting JSON data structures into SQL statements. This plugin does not rely on external networks or third-party services, and all conversion logic is completed locally.

Core Features

  • Pure Node Implementation: depends on a standard Node.js environment, with no additional complex dependencies.
  • No Network, No External Services: all conversion logic is executed locally, with no reliance on third-party API services.

Installation and Enablement

  1. Run the installation command.
  2. Enable the plugin in the configuration file.
dsh plugin add dsh--to-sql

After installation, you need to find the dsh.profile.bundles field in the project’s profile configuration file package.json, and manually add the plugin name.

{
  "dsh": {
    "profile": {
      "bundles": [
        "dsh--to-sql"
      ]
    }
  }
}

Typical Usage

After installing and enabling the plugin in the configuration, you can use the conversion functionality by directly invoking the tool registered by the plugin in a DSH session.

Applicable Scenarios and Notes

  • Applicable Scenarios: scenarios where JSON data needs to be quickly converted into SQL statements for local data processing.
  • Notes: Installation causes third-party code to run on your local machine. Please review the source code and license (MIT) before use.

This tool achieves data format conversion through local computation, making it suitable for scenarios with high requirements for data privacy and network environments.
