dsh-plugin-pkgseek: PkgSeek Linux Packages, Commands, and CVE Intelligence as a Native DSH Tool

dsh-plugin-pkgseek is an open-source plugin for DeepSeek Harness (DSH) that provides agents with Linux system-level capabilities. By integrating with the PkgSeek API, it encapsulates approximately 22 read-only native tools covering command diagnostics, package management, vulnerability intelligence, and lifecycle queries. The plugin supports offline snapshot fallback and offers flexible configuration, requiring a DSH version between 0.1.0-rc.7 and 0.2.0. All tools perform read-only operations, require no API key, and can be installed and enabled from the npm or GitHub source.
