dsh-mcp-skill-list: List MCPs, skills, and Hooks on the machine

DSH configuration files only indicate which plugins are installed, not what is actually connected to this machine. The **dsh-mcp-skill-list** (author jiajinyuan, category admin-security, MIT, DSH web platform) answers this question with two interfaces: the sidebar inventory panel lists server names, transport methods, startup commands, skill sources and paths, and hook declarations across three tabs (MCP / SKILL / HOOK); the conversation header's "Tools" tab counts tool invocations, error counts, and MCP attribution per session and turn. All data is read-only, obtained via profile Loader, skills snapshots, settings files, and sessionQuery event logs, while environment variables only expose key names. Installation uses `plugin_manager install_bundle`; the host registers two same-origin read-only routes and rejects cross-site requests. Suitable for DSH developers who need to debug MCP and skills or review session call chains; source code should be reviewed before installation.
