dsh-skill-manager: DSH Web Local Skill Management Plugin

dsh-skill-manager is a plugin for DeepSeek Harness (DSH) designed to address the pain point of frequently enabling local skills. It integrates skill management into the web settings page, supports scanning skills in user and project directories, and provides features such as search and toggling the "automatic model invocation" switch. The plugin leverages DSH's hot-reload mechanism to dynamically disable skills without restarting, with built-in conflict handling and security mechanisms. Installation requires DSH >= 0.1.5-rc.1.
