dsh-pluginGuard

When you install third-party plugins into DeepSeek Harness, a single plugin that throws during import can take the entire web client down at boot, and nothing was there to protect you. dsh-plugin-guard closes that gap. It adds a Plugin Guard tab under Settings → Plugins that imports every user-level plugin in isolation, strips broken ones from the boot bundle, persists the disable via cordis.patch.yml, and flags them as damaged in the UI so everything else keeps running. Beyond isolation, the tab lets you re-scan, enable, pause, or uninstall user plugins, with the interface automatically following the DSH language setting between English and Chinese. The guard itself depends on zero DSH runtime packages, using only Node.js built-ins and defensive API probes, so a DSH upgrade degrades it gracefully instead of crashing it; its sole network call is a read-only version check against your npm registry, with no telemetry or uploads. A built-in one-click update button detects newer releases and installs them in place, ready after a restart. If a broken plugin is already blocking startup, a standalone guard script (lib/profile-guard.js) can quarantine damaged plugins before the web client even launches. This plugin is well suited for DSH users who juggle multiple third-party plugins and need guaranteed web-client stability, especially those treating DSH as a daily workbench where a plugin failure is not acceptable.
