dsh-tavern-renderer

DeepSeek Harness message bubbles are plain by default: rich Markdown ends up as flat black-on-white text with no visual layering. dsh-tavern-renderer plugs into the native Cordis keyed slot on the display side only, injecting an ordered rendering pipeline into assistant-step, user, and steering nodes without touching host source code. The pipeline covers regex replacement, scoped macro variables, a constrained inline expression evaluator (eval, function calls, prototype access, and constructors are all rejected), Markdown parsing, HTML/CSS whitelist sanitization, and semantic document templates. Every stage can be toggled off or flanked by custom extensions, and none of them modify persisted session events or the model prompt.

The standout feature is eight immersive document templates: a letter with fold crease and wax seal, an exam sheet with scoring boxes, a postcard with stamp and address lines, a classified cipher with redaction bars, a telegram with operator and priority fields, a newspaper clipping with edition and headline, a dossier with agency and handler, and a diary with weather and mood. A model only needs a short fenced block with a template name on the first line followed by regular Markdown; the plugin assembles the full visual structure. All metadata is text-escaped before rendering, and field values can never produce class names, styles, or attributes.

It suits users running role-play, long-form narratives, or document-style outputs in Harness who want SillyTavern-grade visual richness without introducing arbitrary JavaScript execution.
