Install Guard

Pre-installation compatibility preflight guard for the DeepSeek Harness plugin: checks Node/engines, peer versions of the @deepseek-ai core package, and the dsh manifest; supports isolated trial startup and repair installation after confirmation to prevent crashes caused by version incompatibility.

The plugin will be installed here. Keep web if you are unsure.

dsh-install-guard · Plugin Install Guard

Pre-install compatibility guard for DeepSeek Harness plugins. Before you download/install a marketplace plugin, it checks whether the plugin is compatible with your running DeepSeek Harness — and prevents the "version mismatch → service crash / won't boot" failure.

Once installed, it registers a model tool plugin_install_guard so the Agent can run the check before installing.

Checks

CheckDescription
engines.nodeplugin's Node requirement vs current Node
@deepseek-ai/* peerspeer/dependency ranges vs resolved versions
dsh manifestwhether dsh.bundle.patch / dsh.client is declared
isolated trial boot (opt-in trial=true)install into a throwaway profile + --dump-config, actually runs apply to catch runtime/load-time crashes

Install

dsh plugin --profile web add dsh-install-guard

Restart dsh web.

Usage (two-phase, via chat)

1) check:
   plugin_install_guard { spec: "plugin-name", action: "check" }   # add trial: true to run apply
2) install after confirming:
   plugin_install_guard { spec: "plugin-name", action: "install", resolution: { spec: "plugin-name@compatible" } }

Relation to other plugins

  • dsh-doctor = environment health; this plugin = version compatibility.
  • dsh-poison-guard / DSH-Plugin-Market = security/audit; this plugin = compatibility.

Use them together: security audit + compatibility preflight = the full pre-install gate.

Limitations

  • Actively-triggered tool, not an automatic hook on the marketplace install button.
  • Static checks + trial boot reduce but cannot eliminate all third-party-code risk.
