Markdown notebook open above the plain composer
Third-party DeepSeek Harness web plugin: a rich Markdown notebook for the composer region. Its browser half contributes two entries to the composer region that dsh-client-ui-conversation owns: a tool-row toggle (conversation.input.left) and an editor card in the composer context stack (conversation.input.dock). Both entries share one per-session store handle, so the in-progress draft survives closing and reopening the panel, surface remounts, and — because the engine scopes session stores by session id — each session keeps its own notebook.
The editor is a CodeMirror 6 instance over the Markdown language: syntax highlighting for the draft (GFM tables included), native undo/redo and selection, and Enter-key list editing in the Codex style — pressing Enter on a non-empty list item opens the next item (ordered markers increment 1. → 2., checkbox items reopen unchecked, indentation is preserved, and a mid-line caret splits the item), while Enter on an empty item drops the marker and returns the line to plain-text editing. Enter on a non-list line falls through to a plain newline. Tab and Shift-Tab steer list depth: Tab on a list item indents it one level, Shift-Tab outdents one level, and Shift-Tab on a top-level item exits the list (marker and checkbox drop, the text stays); both decline on non-list lines to the editor defaults. Mod+Enter submits.
An Edit / Preview pair of tabs sits at the card's top edge. Preview renders the live draft through marked and sanitizes the result with DOMPurify before it touches the DOM — a read-only look at the formatted Markdown (GFM tables, task lists, fenced code, blockquotes), never a modification of what gets submitted: the draft text rides the send path verbatim. Toggling to Preview hides the CodeMirror host instead of unmounting it, so undo history and caret survive the round-trip.
Enter-key list editing: next item, unchecked checkbox, marker dropped
Submission rides the scope-addressed conversation service's send verb — the same path the plain composer's submit rides — so adjudication, queueing, and prompt-error reporting behave exactly like a typed prompt. A failed send surfaces on the session's composer notice channel and the panel keeps its draft.
The notebook and the native composer are two editing surfaces over one draft: opening the panel adopts whatever the native editor already holds (an empty composer instead receives the notebook's kept draft); while the panel is open, every edit on either side mirrors live to the other — notebook edits ride the session input facade's single setDraft write path, native edits flow back through a subscription on the facade's InputState store applied as a minimal-diff splice (an equality guard breaks the echo loop and preserves a caret outside the edited range); closing leaves the final text in the native editor, and a successful submit clears both surfaces.
How the pieces connect: two composer slots, one session store, one send verb
dsh plugin --profile web add @mars.liu/dsh-rich-editor
The package carries its own bundle patch (cordis.patch.yml adds the ui-rich-editor row); list the bundle in the profile's dsh.profile.bundles if you compose profiles by hand. From a checkout:
pnpm install && pnpm run build && pnpm test
Requires the dsh family at ^0.1.2-alpha.5 (published on npm; the 0.1.2 line removed dsh-client-runtime / dsh-client-web-react, whose APIs now come from dsh-client-store, dsh-client-ui-renderer, dsh-api-session-controller and dsh-session) and a dsh web composition that mounts dsh-client-ui-conversation.
The npm 0.0.1-rc.1 dsh snapshot ships browser loader bundles only — its node halves export almost nothing, and several pre-rename dependency names (dsh-compact, dsh-user-interaction, dsh-type-meta, dsh-client-ui-slash) were never published. This repo works around both:
package.json > overrides points the missing names at empty stubs under vendor/stubs/ (nothing in this plugin's surface imports them);vitest.config.ts resolves every @deepseek-ai/* specifier through the paths map of a local harness checkout's tsconfig.base.json (DSH_CHECKOUT, default ../deepseek-harness) and inlines all @deepseek-ai/dsh-client-* packages, mirroring how in-repo dsh tests reach client APIs.Drop both workarounds when the dsh family republishes a complete, installable closure.
/ and @ trigger integration yet — the notebook does not participate in the slash-command and file-mention pipeline; those gestures belong to the plain composer below it.@codemirror/lang-markdown statically depends on @codemirror/lang-html (which pulls the JavaScript and CSS parsers) even with embedded code highlighting off (codeLanguages: []), and the client bundler inlines the whole chain; a deferred trim would split the editor mount behind a dynamic import.MIT
