Introduction

In the DeepSeek Harness (DSH) ecosystem, plugins are the core way to extend agent capabilities. When an agent needs to access specific, static knowledge bases, writing extra APIs or crawlers can be costly and may introduce network dependencies or maintenance burdens. This section introduces dsh-helium, a pure Node tool for querying helium element data.

What It Is

dsh-helium is a helium element information query plugin maintained by developer istone. It is designed to meet the needs of agents that require fixed helium (Helium) element data, returning standardized element information without internet access.

Core Features

  1. Return complete information: Provides complete data for the helium element, including name, element symbol, atomic number, relative atomic mass, category, group, period, room-temperature state, and electron configuration.
  2. Field-specific queries: Supports querying individual records by field name through the element_field method, making it easy to extract specific data in workflows.
  3. No network dependency: Implemented in pure Node, it does not rely on external network requests and is suitable for offline or restricted network environments.

Installation and Activation

  1. Ensure that DSH is installed in the local environment.
  2. Run the official installation command:
dsh plugin add github:uckkk/dsh-helium

Before installing, note that this plugin depends on @deepseek-ai/cordis (^4.0.1) and @deepseek-ai/dsh-tools (>=0.1.0-rc.6).

Typical Usage

  • Get complete information:
  await element_info();
  • Query by field (for example, query the atomic number):
  await element_field({ field: 'atomic_number' });

Applicable Scenarios and Notes

This plugin is suitable for agent scenarios that need to call basic chemical constants or use a subset of a complex knowledge base. At runtime, the plugin runs with the permissions of the current DSH process. Be sure to check the source code and license (MIT) before installation.

Conclusion

dsh-helium provides a lightweight data source solution. For more plugin details, see: GitHub.
