Introduction

When developing agents or applications with DeepSeek Harness (DSH), the model needs to understand the context of the code repository. Injecting the entire source code directly into the context can consume a large number of tokens and may also interfere with the model’s judgment due to irrelevant code. dsh-repo-map is designed to address this pain point by providing a lightweight perspective that helps the model quickly locate the repository structure and key symbols without loading every line of concrete code.

Plugin Positioning

This is a lightweight, read-only plugin maintained by MkaliezZ. Its core responsibility is to generate a repository structure and symbol mapping for DSH. As a complementary tool to dsh-context-pack, it focuses on outlining the code skeleton rather than providing complete source code content, thereby improving the model’s understanding of the codebase while keeping the context concise.

Core Capabilities

The plugin primarily provides the following functions:

  1. Structure and symbol mapping: It can identify and map the repository’s directory structure, extract key symbol information, and help the model quickly locate code positions.
  2. Non-invasive reading: It runs in read-only mode and does not inject entire source files into the context, avoiding context window overflow.
  3. Intelligent filtering: The plugin automatically recognizes common source code declarations and skips generated or third-party dependency directories such as generated or vendor, retaining only the structural information of core business code.

Installation and Enablement

The plugin is published as an npm package named @mkaliezz/dsh-repo-map. Before installing it, please ensure your Node.js environment is version 20 or later.

npm install @mkaliezz/dsh-repo-map

After installation, it will be loaded as a DSH module. When used together with dsh-context-pack, it can enrich the model’s structural understanding of the codebase.

Notes

  • Read-only plugin: Please make sure your use case allows reading the repository structure. This plugin does not perform any file-modification operations.
  • Environment requirement: Node.js version 20 or higher is required.
  • License: The plugin uses the MIT license. Please review the source code to confirm compliance before use.

Conclusion

dsh-repo-map is a practical tool for balancing context length and model comprehension when working with large codebases. By providing a structured mapping, it enables agents to maintain a clear understanding of the repository without loading all source code.
