dsh-storyboard

End-of-chat Doubao-style visual storyboard for DeepSeek Harness Web.

When a substantive conversation ends (real work done, a plan produced, or a concept explained), the model calls the storyboard tool once and a compact visual card summarizing what was done and how it works appears in the sidebar. A /storyboard [focus] command forces one on demand.

Why it is light

• Server-only plugin — no client bundle, no extra JS shipped to the browser.
• Zero runtime dependencies — node built-ins only (crypto, fs, os, path).
• One self-contained HTML file per storyboard (~5–20 KB): system fonts, inline SVG, no network requests, no CDN, works offline.
• Tiny prompt footprint — the injected guidance section is ~500 characters.
• Storyboards are written under $DSH_HOME/storyboard/<session>/ (default ~/.dsh/storyboard/<session>/).

Install

# from a workspace containing this folder:
dsh plugin --profile web add file:C:\path\to\dsh-storyboard

# or by package name once published:
dsh plugin --profile web add dsh-storyboard

The bundle patch inserts one row (id: storyboard) into the web profile. Disable it by removing that row from the profile (the prompt section, tool, and command are all registered by the row's presence).

Usage

1. Automatic — at the end of a substantive exchange the model generates the card and opens it in the sidebar by itself.
2. On demand — type /storyboard (optionally /storyboard the install steps) in the chat input.

Card sections

Section	Field	Notes
Title / subtitle	title, subtitle	title required, max 40 / 80 chars
How it connects	diagram	≤8 nodes, ≤12 edges, rendered as inline SVG with layered DAG layout + arrowheads
What was done	flow	≤8 numbered steps with optional notes, connected by a vertical rail
Key facts	facts	≤8 label/value pairs in a two-column grid
Timeline	timeline	≤8 dotted-rail events with optional time labels
How it works	howItWorks	≤8 mechanism bullet points

Every string is length-capped and HTML-escaped on the host side; omit a section when you have no content for it.

Development

node test/smoke.mjs   # standalone renderer + registration smoke test (no DSH host needed)

Limitations

• v1 has no settings toggle: presence of the profile row enables the feature.
• Diagram layout is a simple longest-path layering (cycles are capped, not drawn as true cycles).
• The automatic trigger is instruction-based (the model decides a conversation is ending); it is deliberately not a hard hook.
