camel-jbang: Add tui_draw MCP tool for on-screen drawing overlay#23716
Merged
Conversation
Add tui_draw and tui_draw_clear MCP tools that let AI agents draw characters at specific screen coordinates as an overlay on the TUI. Useful for highlighting areas, annotating the screen, or drawing emoji art. All cells sent in a single call to avoid chatty networking. Supports auto-dismiss via duration parameter.
