Each opt-in DeepSeek Harness plugin has a settings page

Project overview

One settings page for every plugin that opts in. An adopting plugin declares its fields; this plugin renders the form, stores the values, serves the browser, and enforces the route's admission check.

If Fabric's split is the analogy: dsh already ships the Mod Menu part — the Settings shell, the Plugins section, and the settings.plugins.tab slot. What was missing is Cloth Config: a declarative form API. That is this.

The first design was a page that auto-discovered every plugin's configuration. It was measured and abandoned, because the premise did not hold.
