Screenshots

The DeckSeek reading view: the execution record folds away and the final answer renders in full; the message rail hugs the right edge; spacing above the task bar and composer stays compact — no hollow gaps under long task lists.

Features

• Reading view: live native steps, thinking, and progress during execution; the process folds away on successful completion, leaving the final answer and interactive cards. An independent DeckSeek tab keeps the original Chat / Trajectory views, input box, model selector, tools, and approvals intact. Every known record kind (system prompts, turn processes, turn stats, …) is adapted; unknown kinds fall back to a copyable raw-record card — DSH is not stable yet, so the fallback stays. Failed tools / commands render as unified error cards: reason, exit code, and an expandable raw record.
• Answer cards: the reply and its copy action sit in a card matching the reasoning/tool surfaces; the copy chip floats over the card's top-right corner on hover, keeping the answer at full density.
• Three reading skins: Paper (typographic flow), Soft (cards), and Terminal (rows) — switch from the dedicated DeckSeek page in DSH settings and it takes effect immediately. Skins express structure, density, type, and radii only; colours always come from host theme tokens, so dark and light themes adapt automatically. Soft is the default.
• Message navigation rail: a minimal right-edge rail of tiny pill marks — one per message you sent, editor-minimap style. It takes no layout space and the reading column stays truly centered; the mark at your reading position widens and highlights, hovering shows a styled "Turn N · title" info bubble, and clicking scrolls that message into view with a landing flash (at the document end the newest message owns the highlight; hidden on narrow widths). Marks compress to fit when turns pile up, so every mark stays visible.
• Conversation export — one click in the reading-view toolbar exports the conversation as a Markdown file (your prompts + the assistant answers, in display order, process folded), filename auto-timestamped.
• Turn keyboard navigation — Alt+Up / Alt+Down jump between your messages using the same landing logic as the rail highlight and flash (inactive while typing in an input).
• Status & follow: the thinking card follows the latest lines and settles at the end; the open-turn status shows "BigFatFish is thinking… {time}" with a live clock, and tools show per-family start/done labels (Reading…/Read, Searching…/Found, Writing…/Written); scrolling up reveals a centered ⬇ back-to-latest button floating above the composer. Sending or steering a message returns the reader to the bottom (pinned follow takes over).
• In-view search: live search across your questions and the model's answers; Cmd/Ctrl+F opens the panel; every match keeps a quiet tint with character-exact highlighting (CSS Custom Highlight API) and the active hit inverts; match counts, previous / next navigation, and jumps that scroll the exact hit into view with a flash highlight.
• Reading position memory: reopening a session returns to your previous reading position with a brief notice; "Back to latest" jumps to the bottom anytime.
• Copy enhancements: one-click code-block copy; every table shows a hover "Copy as CSV" action (RFC 4180 — quotes and newlines handled).
• Bilingual UI (i18n): all reading-view copy follows the DSH app language (Chinese / English) with no restart.
• Long-thinking follow: thinking folds into a fading card that follows two lines; expanding pauses scrolling; resume anytime.
• Generative MCP Apps (SEP-1865): any mcp-app code block in the final answer is auto-mounted as a live interactive card inside a sandbox="allow-scripts allow-forms" iframe, communicating with the host via JSON-RPC postMessage (ui/initialize, ui/resize, ui/submit, ...).
• Adaptive theme & height: live dark/light sync with zero first-frame flash; container height smoothly follows content (60–2400px).
• Lossless fidelity: native Markdown, syntax-highlighted code, math, tables, images, and tool facts render faithfully.
• 120 unit and component tests covering message projection, the Markdown pipeline, SEP-1865 parsing, adaptive height budgeting, two-line streaming follow, and the search / copy / reading-position interactions (happy-dom).

Installation & listings

Published on npm: dsh-deckseek

dsh plugin add dsh-deckseek

Listed in:

• awesome-dsh-plugin (PR #4528 merged)
• awesome-deepseek-harness-plugins / deepseek1024.com (PR #367 merged; the entry upgrades to one-click install once the published npm package is detected)

Development

• Dependencies come from a DSH checkout, not from npm: dev dependencies are linked to a built Harness checkout via node scripts/link-harness-dependencies.mjs <checkout>; do not run pnpm install / pnpm add in this directory.
• package-lock.json is a best-effort artifact refreshed under --legacy-peer-deps: the published @deepseek-ai/dsh-client-ui-settings declares a ^0.0.1-rc.1 peer on @deepseek-ai/dsh-client-ui-primitives that cannot intersect this plugin's 0.1.x range, so strict resolution always ERESOLVEs.
• Therefore do not run npm ci in this directory — it will not reproduce a usable dependency tree.

Other

• Features and usage are also described in the upstream repository: aa2246740/dsh-better-display
• Third-party notices: THIRD_PARTY_NOTICES.md · Changelog: CHANGELOG.md · Design contract: DESIGN.md

v0.7.4 · An unofficial DSH display & interaction enhancement plugin. It only changes presentation and interaction views — never the Agent's core execution, SDK, or model credentials.
