Plugins

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.

Continue the sessions on your computer from a phone browser: scan a QR code, approve the device on the computer, then chat, answer approvals, browse workspace files and manage settings in a mobile interface; connects over the same Wi-Fi or through a Cloudflare Quick Tunnel.

Circuit breaker for idle agent turns: watches agent/assistant-stream and cancels a turn that produces only reasoning — no text and no tool call — after 45s, after 80000 reasoning characters, or on a degenerate repetition pattern (exact repeat unit, sentence-template repeat, sparse repeat, or 6-gram density). On trip it injects a continue instruction that requires the next action to be a tool call, and ships 11 regression cases plus per-gate tuning.

Configuration UI for the official OpenViking memory plugin: connection and user-key setup, local connection diagnostics, a per-session memory toggle in the composer, memory isolation that keeps recall inside the current topic, and recall tuning for score threshold, injected item count, query expansion and excluded URIs.

Web reading tools for text-only agents. Five read-only tools: web_fetch (any URL rendered as clean Markdown or plain text), web_links (inventory of a page's links), web_feed (RSS 2.0 / Atom entries), web_headers (HTTP status, response headers and redirect chain without downloading the body, HEAD with automatic GET fallback), and web_table (HTML tables extracted as structured rows with header detection and colspan/rowspan grid expansion). Transport is Node fetch plus a zero-dependency HTTP proxy implementation (CONNECT tunnelling, absolute-URI requests, NO_PROXY with suffix/wildcard/IPv4-CIDR matching, Proxy-Authorization). Zero runtime dependencies.

Scan a QR code in Settings to open the DeepSeek Harness web UI on your phone inside the active session via a cloudflared quick tunnel.

Add a theme-adjustment panel under Appearance to customize accent, background, foreground, contrast and gradient, applied live through theme token overrides.

AI fortune-telling skill for DeepSeek Harness: feng shui, face reading, BaZi, zodiac, daily divination and Chinese almanac.

Enhanced auto-compaction defaults for DeepSeek Harness agent presets: apply tuned threshold/retention budgets and per-model policies with one command, idempotent with backups and rollback.

Reverse tunnel for the DSH Web GUI: exposes a `dsh --profile web` deployment at a public frp URL and switches the directory picker to the in-app browser, so a phone or remote machine can open and manage the workspace.

Five-layer intent recognition pipeline (rules, pgvector retrieval, Jev scoring, fine-tuned arbitration, LLM fallback) with scenario management UI, PostgreSQL storage and distributable API services.

Remote access gateway for DSH: a browser, or the optional 4 MB Android app, scans a QR code and joins the session already running on the desktop. One-time QR tickets (10 minutes, single use), a 6-digit pairing code matched on both screens, four network entries (SakuraFrp / Cloudflare quick tunnel / LAN / Tailscale), and per-device admission: an online-device limit, online devices pinned first with a green dot, and remove = disconnect plus revoke trust. The gateway listens on 127.0.0.1 only.

Black-box GUI testing for DeepSeek Harness: an AI tester drives a real Windows virtual machine using only screenshots and mouse/keyboard, so its verdicts rest on pixels instead of logs or source code. Ships the dsh-vm-tester plugin with twelve vm_* tools (status, UI tree, screenshot, click, type, type-secret, key, basic key, wait, snapshot, upload, download), a reverse-tunnel guest agent for Windows, and run verification scripts. Needs Windows, VirtualBox 7 and a Windows guest VM with the bundled agent before any vm tool works.

Database access for DeepSeek Harness through the DBHub MCP server: configure MySQL, MariaDB, PostgreSQL, SQLite and SQL Server connections per workspace and environment, then let the agent configure, list, query and search SQLite objects through four fixed tools. Passwords and full connection strings are entered in the settings UI and never accepted as tool arguments, so the model only sees metadata such as mysql://host:3306/db; each environment can be read-only (the model may enable it but not clear it) or reached through a manual SSH tunnel. Every call runs its own short-lived dbhub process and dbhub installs itself when missing.

Screen-sense mode for the dsh-pet desktop pet: captures the primary display every 30 seconds, compares an 8x8 average hash of each frame, and sends the screenshot to the session model when the frame changed (and again after the idle interval even if unchanged) so the pet comments in one short bubble line. Adds /fish, /fish_look and /fish_screen commands, a status and control HTTP pair, and a change threshold plus an idle repeat interval that can be tuned in the plugin config. Windows only (PowerShell WinForms).

Makes the built-in web_fetch tool work when Clash / mihomo runs in TUN mode with fake-ip: it lets the fake-ip address ranges (198.18.0.0/15, fdfe:dcba:9876::/64, 2001:2::/48) past the public-address check that otherwise rejects them, while loopback, private and link-local addresses stay blocked as before. Works with no proxy environment variables and no Clash changes.

Trip-planning agent preset for mainland China that answers in Chinese: queries 12306 train availability, Fliggy and Tuniu flight and hotel prices, and real Amap transit routes, checks closures and weather, and delivers a single offline HTML roadbook with draggable maps, three hotel price tiers and an itemized budget. Ships 9 skills, an environment doctor that walks users through missing API keys, and a patch for the 12306 MCP server; it plans and queries but never books or pays.

Run one instruction on every online Windows and macOS machine, across networks and regions: a dependency-free relay talks to each machine over outbound connections only (Tailscale, a public VPS behind TLS, or a tunnel), every machine runs the command in its own checkout, and results come back with a commit, a working-tree fingerprint and a command hash so an environment mismatch is reported as unverifiable instead of being mistaken for a different result. Sending work needs its own operator token, separate from the per-machine device token.

English edition of Weiwen's Law (KISS's Law): the first and only domain-agnostic white-box causal adjudication middleware for AI agents. Unlike domain-specific causal-inference tooling (statistics/economics/ML) or evidence-gated agent firewalls, it adjudicates *every* tool call along a deterministic structural causal chain (R->S->D->H->M) before execution - across any domain, with no training or per-domain tuning. It blocks destructive and credential-file operations, escalates repeated boundary violations, cuts faulting links until verified-fixed, and gives risk verdicts on un-auditable execution; runs fully local with zero API cost.

Forwards an unattended DeepSeek Harness run's tool-call approvals and ask_user_question prompts to Feishu cards on your phone. The desktop GUI answers first — a card is only sent after `delaySeconds` (120 by default) with no answer there — and a phone approval grants `allowed-once`, so no authority accumulates on the phone. One outbound WebSocket long connection to Feishu: no public IP, domain, tunnel or relay.

Wishing House theme skin with warm amber glow, live moon phases, meteors, typing sparks, procedural chime audio, and daily fortune slips.

Network and proxy doctor for DSH: checks system proxy settings, probes local proxy ports, detects TUN adapters, tests GitHub, TCP and HTTP reachability, scans hosts conflicts and prints concrete suggestions for what to change.

Adds a row at the top of the sidebar that switches the whole Web GUI to another DSH host reached over a loopback port, and shows that host's session state on the row (running, unread activity, or waiting for your answer).

Customer-machine access plugin for deepseek-harness-gateway: opens a single outbound WebSocket to the gateway and relays the machine local dsh web UI over that tunnel using pairing-code + HMAC auth, so no inbound port, port mapping, or public IP is needed.
