Plugins

Right-click session menu and sidebar session manager: pin, rename, archive, fork, export, copy cwd/id/deep link, and open in explorer or a new window.

VS Code/Codex-style file pane for DeepSeek Harness (DSH): split the right sidebar into viewer + file tree, with preview/pin tabs, right-click terminal, and Copy to Chat.

FOFA cyberspace mapping inside the conversation: check the account quota, run FOFA queries and export the full result set into CSV/JSON/TXT files in the session workspace by paging through a time cursor. A CSV or TXT export stopped by its time budget or by an upstream error continues into the same file from the saved cursor, so rows already fetched are kept. Results render as conversation cards (query, match count, file path), and the API key is saved from the plugin page into the Harness credential store.

IMPORTANT: refresh immediately after installation or open /login. An old page showing connection failure or HTTP 401 needs sign-in, not reinstalling; it may be unable to load the plugin notice. Windows 11 Web users can enable background power services from the Power menu without a terminal. Initial setup displays a temporary password on the page, never in terminal logs; initialize in a trusted network and change it immediately. Web-profile lock screen with password/OTP/Passkey, persistent sessions and custom wallpapers. Linux/macOS power controls need the bundled systemd/launchd controller; npm updates require a dedicated managed install, never a shared/global prefix. Electron Desktop is not supported. Stopping interrupts active tasks. Auth kernel adapted from xbzbing/dsh-auth-gateway (MIT); do not co-install, both own the web gateway port.

Deck-generation skill for the National College Student Career Planning Competition. It takes a contestant's profile, materials and photographs, drafts a page-by-page outline for confirmation, then renders a 15-20 page reading-type PPTX (under 15 pages is flagged as a page-count error) using 17 page types, three built-in themes or a user-supplied template; the build audits the estimated layout (text overflow, per-page word count, missing evaluation dimensions, material gaps) and the rendered PDF is checked again for out-of-bounds and overlapping text. Requires Python 3.9+ with python-pptx, python-docx and Pillow; LibreOffice (soffice) and pdftotext are optional for the PDF layout re-check.

Precomputes the compaction summary in the background and commits the held result when pressure compaction fires, removing the foreground model round-trip. Registers itself as the session compaction engine, pins the span it summarised so the payload fingerprint still matches at commit time, prunes tool results before committing, and falls back to the stock foreground path on payload drift or context overflow.

Provider-first model picker for the composer. Every provider is listed in the left rail and its models in the right pane. Providers, models within a provider, and pins reorder by drag or Alt+Arrow; providers take a local display alias; one provider can be the panel default; a model's reasoning levels expand inline; search matches model names, provider names and aliases. Switching goes through the shipped model directory service, so the /model popup and this panel always agree.

Deep-sea tidal-blue theme for the DeepSeek Harness Web client with a single accent color and matte (non-glass) surfaces in light and dark modes. Same-token UI additions: a single-line dock HUD reading real session projections (context usage vs. window, TPS, cache-hit rate, elapsed time), per-turn subagent delegation cards showing token usage and an optional cost estimate from OpenRouter public prices, sidebar pagination with pinned sections and type-to-filter, and model / reasoning-effort / permission controls under the composer. Each addition can be toggled in the plugin settings.

Right-click menus for DSH sidebar rows: on DSH 0.2.2+ both rows use the host menus — workspace rows follow the session grouping (new session, copy path and reveal, pinned open-with apps, an open-with submenu, bulk delete) and session rows extend the menu that opens at the pointer with pinned open-with apps, an open-with submenu and permanent deletion of archived sessions; entries stay in the right-click menu by default and can be opted one by one into the shared "…" menu. On 0.2.1 the workspace menu is drawn by the plugin. Adapted from miao-ge/dsh-sidebar-context-menu and 0imzero/dsh-workspace-menu; do not install it alongside either - all of them attach right-click menus to the same sidebar rows.

In-chat image viewer for DeepSeek Harness: wheel and trackpad pinch zoom at the pointer, two-finger and drag panning, gallery navigation, downloads named from the image description and timestamp, and opening workspace originals in the system default app.

Expose a second-opinion tool: when the main agent is stuck it hands the problem to an independent session, receives a plan back, and continues — without waking or impersonating the user.

Opens chat.deepseek.com in the right sidebar pane from one row in the left sidebar, leaves the current conversation untouched, expands to fullscreen on demand, and shares the sidebar browser cookie jar; a bundled script makes the login survive restarts. Desktop (Electron) only; keeping the login across restarts needs the bundled PowerShell patch, which is Windows-only and must be re-applied after every DSH upgrade.

Mirrors an Android phone or tablet into the DSH right sidebar over adb with mouse and keyboard control, keeping videos, clips and chats next to the desktop instead of in your hand; Opus audio needs Android 11+, Windows only.

Multi-session overview: list every session grouped by workspace with live status, pin up to three side by side to read their conversation text, and send a message or interrupt any of them without switching away.

Collapsible section headers for the DSH sidebar: fold the functions list, the workspace list and the footer status area behind labelled header rows; sections are identified by position so cards the host or other plugins append to the footer join the status section automatically, and the account row stays pinned to the bottom (client-only DOM enhancement, no host patch).

One MCP tool surface over two Windows desktop-automation backends (dsh-computer-use-win and windows-mcp). Both must be installed first: dsh-computer-use-win as a DSH plugin, windows-mcp via uv tool install windows-mcp --python 3.14, then run the bundled scripts/patch-backend.mjs once (it rewrites the local windows-mcp source; without it screenshot/read_webpage/launch_app fail) and disable the standalone wincu mount. It merges their 44 tools into 29 by dropping 10 duplicates, 4 dangerous ones (PowerShell, Registry, FileSystem, Process) and 1 tool-management entry, and blocks dangerous calls before forwarding through a reversibility-graded guard.

Pins the first prompt of the current session in a scroll-proof bar above the conversation: one-click copy, a panel listing every prompt you sent (click a row to jump straight to that message, paging back through history when needed), and ten switchable looks (four of them light) you pick from inside the panel.

Saves tokens in DeepSeek Harness sessions by reading any file by line range or symbol mention instead of whole, and by bounding oversized tool results while keeping a recovery path. Pruning happens at the source, not after content reaches the context. Measured 43.9% fewer prompt tokens in a modelled 30-step session.

Shows a dimmed suggestion of the user's next message in the empty composer after a settled turn; Tab accepts it into the draft and Escape or typing dismisses it.

Adds a button to the composer that restates your draft, then asks a few questions with clickable options — every question offers an "I don't know, you decide" escape — and only then rewrites the draft into a request an agent can start on. The whole flow can be finished without typing, and it never sends for you.

Windows only: a night-and-moon themed floating button (a sleepy DeepSeek-chan whale mascot, awake/sleeping artwork) in the bottom-right corner arms the plugin — click it to power the machine off once every root Agent session has gone idle, and click it again to disarm. The button is draggable (position remembered in localStorage), automatically dodges other plugins' corner popups, and survives the frontend re-rendering it away. When the batch finishes a 60 s cancellable countdown starts (configurable 10–600 s) with the remaining seconds on the button and a matching banner: clicking Cancel runs shutdown /a and disarms the mode, and any new session starting during the countdown aborts it. A right-click menu on the button switches the shutdown condition between only-on-success and shutdown-regardless, persisted across restarts in $DSH_HOME/deepseek-chan-sleep-shutdown.json. Zero runtime dependencies.

Edit a sent message in place and resend it as a forked chat, keeping the original: change the text, remove, reorder or add images and files, with session image limits checked before sending (the first message opens a new chat in the same workspace). Also @-references pending images by file name, drag-reorders composer attachments, copies messages together with their images, and adds copy, download and drag-to-composer for images in the conversation.

Native generation-time Mixture-of-Agents: every turn, reference models run the same session context in parallel as pre-run drafts and one aggregator executes with full tooling; config-as-model recipes, F mirror / R trimmed views, enforced subagent gating (dual-shape session indexing), derived per-recipe vision (vision refs relay image reads to text-only aggregators), tiered cadence with separate steering and patrol rosters plus frozen reuse between beats, degeneration guard dropping degenerate reference output, anonymized model face (failure notices carry no provider identity), and cache-friendly guidance placement (the rehearsal record is pinned where it was produced instead of appended to every request, so the cached prefix covers it and each step pays only for what was added since - on by default across every cadence).

DeepSeek Harness plugin: a Sourcetree-style Git workspace — branches, diff, history, fetch/pull/push, AI-written commit messages and AI-assisted conflict resolution, with pinned and usage-ordered repositories.
