dsh-teaching-board

When an agent emits a self-contained HTML document, a text-only chat makes it hard to actually explain what is on the page. dsh-teaching-board projects that HTML into a sandboxed iframe inside a dedicated "teaching board" tab of the DSH conversation, turning raw markup into a visual surface where both sides can point, annotate, and iterate together.\n\nThe board model treats one board as one topic: the same board id can be appended to, patched by region, or partially cleared without a full reload, so scroll position, hand-drawn strokes, and animation state all survive. Users can sketch with four colors, erase, undo, and capture a zero-network screenshot (document cloned to canvas) that is delivered back as a genuine user message the agent can see on the next turn. The plugin also ships a bundled skill set covering typography, layout, visual guidelines, and asset libraries, activated immediately upon install with no extra preset required.\n\nIt fits workflows where structured in-chat explanation matters: walking through code concepts, visualizing reports and proposals, classroom-style demonstrations, or any loop in which the agent produces a board, the human adds strokes and questions, and the conversation keeps building on the same surface. It does not replace long documents or slideshows; it gives every agent output a living board you can keep writing on and share back.
