Introduction

The core philosophy of DeepSeek Harness (DSH) is “everything is a plugin.” Developers can quickly build agents for specific scenarios by combining plugins. When developing business agents for the Vietnam market, they typically need to handle three frequent and error-prone tasks: converting numbers into Vietnamese dong amount text, generating VietQR transfer QR codes that meet standards, and querying real business information by tax code (MST). Asking a large model to handle these tasks directly can easily lead to format errors or hallucinations, especially when querying business information. The mikegabyte/dsh-vn-biz plugin introduced below is intended to address these issues.

Core Features

This plugin provides three basic tools for local Vietnamese business scenarios:

  1. VNĐ amount to words: Converts a number into Vietnamese dong amount text.
  2. VietQR quick-link: Generates a VietQR transfer QR code link.
  3. Tax code lookup: Queries business information by tax code (MST).

Installation and Activation

The installation process mainly involves cloning the code, building dependencies, and registering the plugin.

  1. Clone the repository locally:
git clone <repo-url> dsh-vn-biz
cd dsh-vn-biz
  1. Install dependencies and build the project:
npm install
npm run build
  1. Add the plugin to the specified DSH profile:
dsh plugin --profile <ten-profile> add /path/to/dsh-vn-biz

After installation, the dsh web service must be restarted for the new plugin to be recognized.

Typical Usage

After installation, the agent can invoke the above tools through natural language:

  • Amount to words:
    Đổi số tiền 15750000 sang chữ giúp mình
  • Generate a VietQR QR code:
    Tạo QR chuyển khoản Vietinbank số 113366668888, tên NGUYEN VAN A, 500000đ, nội dung 'thanh toan hoa don thang 8'.
  • Query business information:
    Tra công ty mã số thuế 0100109106 giúp mình

Applicable Scenarios and Notes

Keep in mind the following limitations when using it:

  • Input limitations: amount_to_words only supports non-negative integers (VNĐ amounts do not use decimals in real business scenarios).
  • Network dependency: tax_code_lookup and vietqr_quicklink depend on the public api.vietqr.io and img.vietqr.io endpoints. No API key is required, but there is no service level agreement (SLA) guarantee.
  • Permissions and compliance: The plugin runs with the permissions of the current DSH process. Source code and license (MIT) should be reviewed before installation.

Conclusion

By wrapping fixed algorithms and directly calling public data endpoints, the plugin reduces hallucination risk for agents in local Vietnamese business scenarios and improves the accuracy of instruction execution. For more details, refer to the community catalog or source repository.
