Plugins

Floating workspace file-preview window for the Web client: lazy file tree, CodeMirror preview and in-window edit with save, Markdown and image preview, Quick Open search, and opening paths clicked in the conversation.

Persistent image or MP4 wallpaper for the DSH Web profile: a wallpaper card under Settings -> General selects a local image or MP4 (up to 300 MB), tunes surface opacity and blur, compresses video locally to H.264 when ffmpeg/ffprobe are on PATH, stores media under ~/.dsh/wallpapers, and pins the Web server to port 9191 so the saved wallpaper survives restarts.

Self-protection guardrails for the DeepSeek Harness: protected-path interception, backup-before-destroy, CLI self-recovery commands, and strict sandbox defaulting

Global experience archive for DeepSeek Harness on Windows: probes local tools (with versions and PATH-first hits), convenient paths, network latency and disk speed; folds per-session stats from session/event; LLM-extracts durable facts; env_profile tool with remember; byte-stable summary injected every turn to speed up sessions and cut token use.

Model-facing image_describe (识图) tool over the DashScope OpenAI-compatible API (qwen3.7-flash), plus a paste bridge: on text-only sessions, pasted images auto-convert to file paths at send time and render back in the transcript, so they never trip image admission. Bring your own DASHSCOPE_API_KEY; endpoint/model/budgets configurable, redirect-proof HTTP client, works in every agent preset.

DSH Web skin manager for mainstream DSH skin packages: import local paths or GitHub collections, scan installed skins from the web profile, preview/use/disable/refresh/delete, with host-side persistence.

Ctrl+click file paths and links in chat: paths open their folder in the OS file manager (with the file selected), links open in a new browser tab.

Line-range selection: browse workspace files, preview code with line numbers, visually select a line range, and write a `@path:start-end` reference into the composer; the agent receives the exact selected lines on send.

Bring any file into the conversation — stashed to the workspace and referenced by path; zero type rejection

DSH plugin: Windows correctness layer — GBK/GB18030/UTF-16/Big5/Shift-JIS encoding detection with confidence and lossy reporting, Windows path legality (reserved device names, 8.3, UNC, MAX_PATH), netstat interpretation and bounded read-only disk inspecti

DSH plugin: 29 deterministic, offline tools for JSON validation with exact line/column, JSONPath queries, YAML/CSV conversion, text diff, regex capture, encodings, hashes, Unicode, CIDR, JWT structure and timestamps. Every call returns a { result, meta }

Synchronize DSH sessions, settings, attachments and project files using a user-configured private HTTPS Git repository or SFTP, with safe-scope online application, offline restore plans and user-confirmed plugin updates. Requires Node.js 24+; the SFTP path also requires OpenSSH (ssh/sftp).

An independent permission gate above the built-in sandbox. It blocks writes outside the workspace and to protected paths even under danger-full-access, refuses whole-file overwrites without a complete fresh read, and keeps ZIP restore points plus Recycle Bin copies before destructive actions.

Pre-execution guard: a `tools.guard` predicate decides allow, ask or refuse per permission preset for dangerous shell commands (git hook bypass, catastrophic `rm`, download-and-run, git history rewrites) and for edits to credential paths or to files the turn never read, and hands the model the reason plus a working alternative.

Windows only; the upgrade path needs DSH_AUTO_UPDATE_LAUNCH_CMD configured. Checks, installs and rolls back DeepSeek Harness CLI updates from the web settings page, switching the launcher pointer only after the new version passes a config-tree check and a health-checked restart, and reverting automatically when it does not boot.

Outbound route pool for DeepSeek Harness. Ships 15 seed routes plus a 20-entry candidate pool covering 7 target kinds (GitHub raw/codeload/main, npm registry, PyPI index, HuggingFace, general). Routes are verified before use: upstream IP lists go through a TLS handshake with full certificate-chain validation (a bare TCP check can be answered locally and report dead IPs as healthy), and failures advance a cooldown ladder of 2/5/15 minutes with the fastest healthy route picked per target kind. Routes are applied by rewriting the URL with one of four rules (prefix, registry, index, host-replace), reaching git, pip, npm, pnpm, gh, curl and wget through three paths: the shell seam (download commands the model runs through the bash tool are intercepted and rewritten automatically; commands wrapped by the pwsh tool, and fetches made by the host itself or the renderer, are not covered), two registered tools the model can call directly (line_pool_status, line_pool_run), and child-process spawn. Multi-line commands keep their line breaks and only the download segment is touched. URLs carrying credentials (user:token@host) are never rewritten, so tokens are not forwarded to third-party mirrors. No global config is modified. A sidebar panel lists every route with latency, failure reason and cooldown countdown, supports per-route retest and enable/disable, and shows live TUN/proxy status from network-adapter and loopback port checks. The candidate pool is re-verified every 24 hours so newly usable routes are added and dead ones dropped. 570 tests, 87% line coverage.

Requires mise installed on the host. A mise-backed toolchain manager for the host machine — a settings page listing the active, installed and available versions, with .mise.toml-driven install, use, uninstall and prune, mise shims prepended to the host PATH on load, and nine agent tools for the same work (status, versions, PATH scan, install, use, prune, uninstall, activate, progress).

Hot-reloads DSH plugin modules without restarting the app (module-cache purge, junction-path matching, bust fallback) and registers a refresh button in the session header so the browser page loads the new plugin bundles.

Move an entire dsh installation to another machine and check it item by item. Three layers go across: the declaration layer (settings, credentials, plugin declarations and vendored link: sources), the state layer (sessions, storages, skills, attachments) and, optionally, the workspace project code. Sessions are rewritten at the zstd header frame only, workspace paths are remapped through an explicit path mapping, and at the end 14 checks (I1–I13 plus I6b) report PASS / FAIL / WARN. A LAN route pairs two machines and pulls the bundle over directly; merge mode diffs a bundle against a machine that has already been in use and stops before writing anything while conflicts are undecided.

Keep a DSH profile identical across machines through any WebDAV server. The plugin collects the five parts that make up a setup — models (the llm-pi-ai line of cordis.patch.yml), defaults (the agent-default-model line), patch (the remaining loader lines), plugins (package.json dependencies plus dsh.profile.bundles) and dirs (extra absolute-path directories picked in the panel, carried whole and restored to the same path, add-only, at most 5 with 2000 files / 8 MiB each) — encrypts them on this machine with a passphrase (AES-256-GCM, PBKDF2-SHA256 at 600000 iterations) and uploads one ciphertext file to <address>/dsh-webdav/dsh-profile.prop, so the server only ever holds the sealed copy (the older dsh-profile.dshsync name is still read). Merging is per part and three-way against the last synced baseline; a conflict keeps the newer copy and archives the losing one under sync/ (latest 5 per tag), every overwrite is sealed beforehand, and deletions propagate except in the plugins part, on the first sync, and in the dirs part, where dropping a directory on one machine only stops syncing it there and never deletes its files. Uploads carry ETag If-Match and If-None-Match so a concurrent change is refused instead of being clobbered. Sync runs on demand or on a 3/15/30/60 minute timer from a settings panel, and an optional local forwarder (off by default, loopback-only) re-serves the same target with locally generated credentials, rewritten PROPFIND hrefs and .prop aliases for extensionless resources. The local state lives in <profileDir>/.dsh-webdav-sync/ (sync.json is written 0600 and holds the WebDAV password and the passphrase).

Command resolution forensics: which file a command actually runs, which PATH entry won, what it shadows, how many entries are duplicates or dead, and whether the copies behind one name report the same version.

Turn-finished music reminder: when an agent turn ends, play a ringtone or any local audio file (bundled synthesised telephone ring, custom absolute path, or an in-page upload), with a floating chip to pause, resume or dismiss it and loop-until-paused playback; configured in Settings, defaults overridable per deployment.

Injects a very short conventions reminder (absolute INDEX path + version) once per session per version; when the conventions version changes, the next turn re-injects it (chat turns included). Optional hard guard: on operation-like turns, write/edit tools are rejected until the session has read the index (chat turns and shell are not blocked by default). Ships example checklists or points at your own directory; zero dependencies, configurable paths. Solves: conventions are written down but never pulled up when the work starts.

Reads a local video or page link with ffmpeg and Paraformer ASR, returning a timestamped transcript plus key-frame images the agent can open; finds candidate videos by keyword and installs its own runtime dependencies on first use. Requires Python 3.8+ on PATH; video_discover also needs a one-time douyin/xiaohongshu login.
