This repository is a native DSH plugin built exclusively for the DeepSeek Harness ecosystem, designed to check the health of newly installed DSH plugins. When a user adds a new plugin to their DSH instance, this tool runs a full suite of checks before the backend is restarted, catching issues that would otherwise only appear on the next boot. To install it, you first create the DSH plugins directory if it does not exist, clone the repository into that folder, then add it to your web profile via the DSH CLI command, and finally restart the DSH backend to access it through the settings panel.

The core problem this plugin addresses is that DSH’s native plugin installation command only adds the plugin to the user profile and does no validation before the next backend restart. This means common issues like missing dependency chunks, duplicate core module instances, or incorrect cordis usage only get caught when the user restarts DSH, leading to avoidable downtime and debugging work. This plugin runs 9 different static and dynamic checks before restart, and automatically rolls back problematic plugins if issues are found, saving users time and frustration. After running a check, results are displayed with clear severity badges and one-click repair options for detected issues.

The plugin includes four levels of checking: L0 static analysis that does not load or run plugin code, L1 configuration combination checks, L2 isolated trial runs in a subprocess, and a static malware scan that checks for 7 common types of malicious code patterns. The malware scan follows a strict isolation rule that only reads plugin files and never executes code, to avoid activating any malicious content before detection. All automatic repair operations follow a hard rule that they never modify DSH core source code, only changing plugin code or configuration files, and require explicit user confirmation before any changes are made.
