dsh-watcher: Automatic API Change Comparison and Impact Analysis Tool for DeepSeek Harness Plugins

dsh-watcher is an automatic API comparison tool for DeepSeek Harness (DSH), used to detect breaking changes during plugin upgrades. It performs AST-level diff analysis based on official repository history and documentation, providing breaking-change detection, plugin impact analysis, a daily feedback radar, and CI monitoring. Users must configure the official repository path, compare versions through PowerShell scripts, and view Markdown or JSON reports. The tool uses a conservative strategy to identify breaking changes; after installation, restart DSH, and the Agent can perform pre-upgrade comparison and modifications according to the prescribed procedure.
