Interactive UI
Running hermes plugins with no arguments opens a composite interactive screen: General Plugins section - checkboxes, toggle with SPACE. A row opens checked when the plugin is active right now: listed in plugins.enabled , or a bundled platform, backend or model provider (on without a list entry), or the selected provider of a category. Only rows you flip are written on exit: unticking adds the plugin to plugins.disabled (explicit off), ticking adds it to plugins.enabled and clears a stale disable. Opening the picker and leaving changes nothing. Provider Plugins section - shows current selection. Press ENTER to drill into a radio picker where you choose one active provider. Bundled plugins appear in the same list with a [bundled] tag. Provider plugin selections are saved to config.yaml :
