Plugins

Build and manage dsh agent modes from the settings page: start each one from the official standard / PTC / minimal / Cordis composition, toggle the plugin rows it mounts one by one, rename it, and edit its system prompt — a plain file the agent loop re-reads before every model step, so an edit applies to the running session on its next step. Rows left untouched stay byte-identical to the shipped ones, platform conditions included.

Custom modes and custom prompts for DeepSeek Harness (dsh): edit a mode's system prompt on the settings page (it takes effect on the next model step), choose its base mode, switch plugins row by row, and keep several assistants side by side.
