Introduction

The core design philosophy of DeepSeek Harness is “everything is a plugin.” When building agents or custom toolchains, developers often face a need to handle key mapping and indexing logic locally. Introducing network requests would increase latency and raise the risk of a single point of failure. Below is an introduction to dsh-key-by, a local tool designed specifically to address this kind of requirement.

What It Is

dsh-key-by is a DSH client plugin maintained by developer uckkk. It is implemented purely in Node.js and relies on no external network services. The plugin registers tools through the Cordis patch mechanism, making them directly callable from DSH sessions.

Core Capabilities

Based on current information, the core capabilities of this plugin lie in its runtime environment:
* Pure Node.js implementation.
* No network dependency.
* Once installed, it registers tools that can be called directly in a session.

Installation and Enablement

  1. Install it via the official command-line tool:
dsh plugin add github:uckkk/dsh-key-by
  1. After installation, invoke the tool registered by the plugin in a DSH session to use it.

Use Cases and Notes

  • Target audience: developers who need to execute key indexing logic locally and prefer a lightweight, network-independent solution.
  • Permission note: The plugin runs with the permissions of the current DSH process.
  • Prerequisites: Ensure that your local environment satisfies the peerDependencies requirements, including @deepseek-ai/cordis: ^4.0.1 and @deepseek-ai/dsh-tools: >=0.1.0-rc.6.
  • Security recommendation: Before installation, it is recommended to review the GitHub source code to confirm that the logic meets expectations, and to confirm that the license (MIT) complies with project standards.

Conclusion

For local, network-independent key indexing scenarios, dsh-key-by provides a ready-to-use solution. For more technical details and source code, please visit the GitHub repository.
