dsh-history-sync

DeepSeek Harness (DSH) is a powerful local AI workspace, but it typically requires manually creating sessions to trace conversation history. The dsh-history-sync plugin addresses this pain point by acting as a one-way, read-only mirror that seamlessly imports Codex and Claude Code history into DSH. It preserves the integrity of your original data by safely extracting conversations and automatically creating or reusing DSH Workspaces based on project directories, making project grouping intuitive and simple.

The plugin's core capability lies in its intelligent synchronization mechanism. By utilizing Codex's stdio protocol and the official Claude Agent SDK, it efficiently extracts dialogue content while handling large-scale histories through content fingerprinting and incremental sync algorithms. It supports intelligent filtering to automatically skip system messages, tool calls, and other noise, ensuring imported sessions are clean and relevant. Additionally, it offers a preview mode, allowing users to verify the sync scope before final import, guaranteeing data safety and accuracy.

This is an ideal solution for developers seeking to unify their workflow and manage multiple AI tools from a single interface. It is particularly suitable for users with extensive Codex and Claude Code histories who want to bring this context into DSH for centralized retrieval and management. With simple configuration, it transforms scattered tasks into structured projects, significantly boosting development efficiency and context management capabilities.
