dsh-session-settings

Managing per-session model choices, MCP tool toggles, and skill enablement in the DeepSeek Harness Web GUI has always been a hassle — editing config files, restarting the service, and hoping for the best. The dsh-session-settings plugin consolidates all of it into a single sidebar section with a dedicated conversation-view tab, so every change you make is picked up on the very next request without a single restart.

Under the hood it delivers four capabilities: (1) independent subagent model and reasoning-effort control for subagent, subagent_fork, and workflow roles, switchable between global-default, parent-session-inherited, or fully custom modes; (2) centralized MCP server management with two-stage compatibility probing, automatic protocol downgrade, and inline tool schema inspection; (3) granular per-session MCP tool enable/disable on top of your global defaults; and (4) per-session skill-level control over bundled, user, and project skills, with automatic dynamic prompt catalog filtering and execution enforcement built in.

If you juggle multiple MCP services, maintain several skill sets, or need to swap model combinations between sessions on the fly, this plugin removes the friction — make the change in the GUI, and it is live the moment you hit save.
