Introduction

In the development workflow of DeepSeek Harness (DSH), quickly reusing previously sent prompts or reviewing context is a common need. Existing interfaces usually rely on scrolling or copy-pasting, which is not always smooth. The dsh-input-history plugin aims to solve this with two complementary interaction modes: terminal-style keyboard history browsing and a searchable /history panel.

Plugin Introduction

loommii/dsh-input-history is a client-side plugin that provides terminal-style input history. It allows users to replace the input box content directly using arrow keys (↑/↓) without popping up a list, or to open a searchable floating panel via the /history command. The plugin reads the full log of the current session, isolates data by session, and automatically collapses adjacent duplicate messages.

Core Features

  1. Terminal-style arrow-key browsing
    When the input box is empty or the cursor is at the beginning, pressing ↑ or ↓ replaces the input box content with the most recently sent message. This mode does not open a popup and resembles Shell history navigation.

  2. Searchable floating panel
    Open a floating list with the /history command. It supports mouse selection, and also supports ↑/↓ plus Enter inside the panel.

  3. Insertion mode
    When /history is selected from the slash menu, the plugin enters insertion mode and inserts the selected message at the position of the /history token, preserving the surrounding context.

  4. Data processing behavior
    * Session isolation: Data is strictly isolated by session.
    * Data source: It reads from the full log of the current session, including pagination.
    * Automatic collapsing: Adjacent duplicate messages are collapsed automatically.

Installation and Activation

Run the following command to install the plugin. After installation, restart the profile for changes to take effect.

dsh plugin --profile web add @loommii/dsh-input-history@latest

You can also install it from GitHub:

dsh plugin --profile web add github:loommii/dsh-input-history

Upgrade or uninstall:

dsh plugin --profile web update @loommii/dsh-input-history
dsh plugin --profile web remove @loommii/dsh-input-history

Typical Usage

  1. Terminal-style browsing
    Focus the chat input box in any session, ensure it is empty or the cursor is at the beginning, then press ↑ or ↓ to browse messages sent in that session.

  2. History panel
    Type /history and select it from the slash menu, or press Enter directly to open the history panel. You can use the search filter inside the panel to find specific messages.

  3. Cancel operation
    In terminal-style browsing or panel operations, press ESC or click outside the panel to cancel and restore the draft.

Use Cases and Notes

This plugin is suitable for DSH developers who frequently adjust prompts or trace back context. It is a purely client-side plugin and does not require host-side code changes. It reads data from the full log of the current session. Before using it, make sure the host environment version is compatible (dsh >= 0.1.7-rc.1). The plugin is released under the MIT License.

Conclusion

dsh-input-history lowers the barrier to reusing messages in long conversations by introducing terminal-style keyboard interaction and a structured search panel. For developers who are accustomed to arrow-key navigation, this popup-free browsing mode can significantly improve input efficiency.
