Ctrl+F find-in-session for the conversation, powered by the session store rather than the DOM - labels every hit by source (you / assistant / reasoning / tool call / tool result / system), groups results by turn, merges identical snippets, offers prose-vs-everything scope, regex / case / whole-word options, highlights all matches, and copies or exports the result set as Markdown.

Brings the free models of a locally installed OpenCode CLI into DSH: starts or reuses a local opencode serve, discovers the live catalog and refreshes it every five minutes, and bridges the session event stream to OpenAI-compatible SSE through a loopback-only shim that validates Host and Origin.

Claude Design System theme for DeepSeek Harness: warm-grey surfaces and a clay accent, refined composer, sidebar, code blocks and Markdown, localized edit/write cards with workspace-relative paths, and an ASCII ocean on the blank-session page with three whale colour modes.

An Everforest colour theme for DeepSeek Harness, for both web and desktop. Forest tones, with six dark and light palettes. Chat content (headings, code, links, tables and more) is restyled with independent colours, and every tone and saturation level is tuned individually for a warm, gentle, easy-on-the-eyes experience.

Usage panel on the blank-session hero: sessions, messages, total tokens, active days, peak hour, favourite model and a contribution heatmap, over all time, 30 days or 7 days.

Separate font slots for content, code and terminal text, plus an interface font, an interface-size stepper and an inline-code size stepper, with line-height and letter-spacing controls. Typography only — it never touches colour.

Next-prompt suggestions: after each answer it predicts your next message as grey ghost text in the composer. Tab fills it without sending, and the prediction model is selectable.

Generative UI: the model calls render_ui with a React snippet and the answer renders as an interactive card in the conversation. The snippet runs in a sandboxed iframe with an opaque origin, so it cannot read the host page, its storage or its cookies, and the frame CSP blocks the network; a message from a card is only sent after the user confirms it, and a failing card shows its error with the source behind a toggle.

Element-level PowerPoint canvas that edits the opened .pptx in place: click, marquee-select or pick a whole slide, describe the change, and the AI writes byte-preserving OOXML patches with undo and redo.

Arknights-flavoured startup animation for the DSH Web GUI: a PRTS terminal boot, sonar scan, hologram lock-on and an operator-file splash that end in a deep-sea lockup, about 4.6 seconds, with four selectable original score presets (or sound off), skippable with a click or Esc and switchable, re-timed or replayed from Settings.

Long-term memory for DSH stored as plain Markdown. Real user/assistant exchanges are captured into daily session files without a model call; an LLM pass then distils them into memories that are injected into the system prompt each turn. Retrieval is local (CJK bigram + BM25) in three levels — index, summary, full text — so the model only pays for the detail it asks for. Memories carry priorities; P0 and user-written entries are never changed automatically, and forgetting marks an entry stale instead of deleting it, so the whole chain stays auditable in status.md. Six tools cover recall, write, status, extract, feedback and the skill library; when a cluster of memories is ready to become a skill, a card appears at the end of the turn, writes the SKILL.md on click, and installs it only after you approve. Learning is on by default and follows the conversation model; turning the master switch off stops the LLM entirely while capture keeps working. Failures are surfaced in the prompt and in status.md instead of being swallowed. Pure JavaScript, no third-party runtime dependencies beyond the harness packages.

Plugin index inside DSH that lists over 10,000 third-party plugins checked against the dsh.bundle manifest in their package.json rather than by star count, with one-click install and a companion website.

Diagnoses third-party LLM API endpoints from the sidebar: a four-layer check (DNS/TCP/TLS, key and model, a real streaming conversation, then timed repeat runs) reporting time-to-first-token, output speed and success rate, with every failure attributed to the step it stalled at and the byte count that actually left the machine. 37 provider presets, no model names hardcoded.

Push DSH task results to the Huawei HarmonyOS assistant-today screen as service cards. After installing, enter the auth code on the plugin settings page: DSH top-left Plugins - dsh-harmonyos-hiboard.

Cross-session memory kept as a short Markdown living document that is rewritten in full at the end of every turn, written to by model tools, the page, and automatic rewriting alike.

Unofficial Volcengine Ark Coding Plan LLM provider: registers an `ark-coding` route with 12 models (capacity facts measured per model), multi-account with automatic rotation, a bundled pinned arkcli for the official model catalog and live plan quota, plus a settings wizard and a sidebar usage card.

A Neon Genesis Evangelion-inspired skin for DeepSeek Harness: Title Card (light) and Central Dogma (dark) modes over one removable override layer, 55 measured color tokens, a wallpaper paint layer whose two surface alphas are solved against a WCAG contrast budget, a boot mask and a brand mark. It also rewrites the sidebar identity line, replaces the new-session heading, hides six official entries, and reshapes the composer control row. Unofficial fan work, non-commercial: the background pictures are fetched from third-party URLs at paint time, not shipped in the repository.

Turn any DSH selection into a reviewable quote — chat, file preview, terminal and diff; code quotes carry path#line. A sent quote keeps a source highlight and ordinal and jumps back, then joins a searchable review list with status, tags, multi-select insert, and Markdown/JSON export. Quotes collect above the composer as a 引用 ×N bar with per-chip edit and remove; side threads can bring their conclusion back to the main draft; a sent quote can be revised, with the old capsule marked superseded; replies can answer each quote by number.

Selection quoting and anchored annotations across DSH chats and document previews: numbered quote blocks stay visible in the composer and in sent messages and click back to the source, notes from docx / PDF / Markdown / code / Excel-range previews collect into one batched send, and each note can be dictated by voice.

Model failover and turn keep-alive for DeepSeek Harness: a request that fails with a model error before any visible output falls through the models of the configured provider groups (then the next provider) until one streams; transient failures retry with backoff under a liveness watchdog, a dead turn self-resumes with templated 「继续」 wake-ups, and an optional full-auto mode auto-answers permission, question and plan approvals with every decision appended to an AUTO-MODE.md audit log.

Desktop notifications for DSH: a system toast, a per-kind chime and a tab-title marker when the agent needs you (approval, plan review, question) or a reply finishes in the background; errors, interrupts, usage limits and multi-agent workflow progress alert too. A host half adds SSE delivery, webhook push (WeCom/Feishu/DingTalk/generic), per-turn token/cache/TPS stats, plus three message-format presets (concise, detailed, custom); settings changes auto-save.

Native right-sidebar Markdown preview with Mermaid diagrams, KaTeX math, GFM tables and syntax highlighting — rendering engine bundled, fully offline.

A lightweight font and theme plugin for the DSH client: Latin/Chinese/code font pickers that list only installed families, and five official palettes (One Dark Pro, Dracula, Nord, GitHub, Catppuccin) applied through the official theme tokens, including code-block syntax colors. No bundled fonts, no dependencies, no build step. Requires DSH 0.2.0-rc.2 or newer.

Custom branding for the shared DSH Web UI: a Settings → Branding panel for the name, badge, and local logo/wordmark images with size and rounding, live preview, optional page-title brand, and reset to the official look.
