Plugins

Zero-dependency toolkit: time / encoding / json / calculator / csv / regex / markdown / diff / stat / schema — ten deterministic tools in one install.

H.D.D skin for the DSH Web UI: a voiced full-screen boot animation, an animated eye core (idle / thinking / done) you can drag or hide, a brand swap on the new-chat hero, a time-of-day greeting, a usage bubble with balance, today spend and the peak/off-peak countdown, the Fairy-mode agent preset, and optional local GPT-SoVITS voice.

Isolated-environment browser verification skill for DSH plugin development: a throwaway DSH_HOME, its own `verify_<random>` profile, its own port and its own browser instance in one command, cleaned up on exit, so the profile you are actually using is never touched; ships a zero-dependency raw-CDP driver (snapshot / click / screenshot / eval) and an optional isolation audit.

Multi-provider usage stats framework (v2 adapter contract): persistent capsule plus detail panel; DeepSeek official (interval-bookkeeping daily usage derivation with a peak/valley countdown badge, working even without an official usage endpoint) and OpenCode Go built in; any other data source joins by dropping in a single mjs adapter file, hot-swappable from the settings page, with API keys kept on the host.

Visual multi-agent DAG workflows for DeepSeek Harness with live execution, restart recovery, and Feishu integration.

Free conversational ChatGPT Web (GPT 5.6 Luna) model provider for DeepSeek Harness with streaming Markdown.

Syncs the wallpaper currently applied in Wallpaper Engine to the DSH Web UI background through a local bridge: preview/capture/full render modes, monitor lock, a wallpaper library panel for local and market content, focus lens with eye tracking, immersive mode, and a Windows app launcher that installs software from direct links or a cloud-drive share link and starts it with one click.

A DeepSeek Harness (dsh) plugin — turns dsh web into a SillyTavern-style roleplay frontend: character cards, prompt presets, lorebooks, personas, BM25 long-term memory, world-state deltas, and rollback-able floor operations, all on the dsh agent runtime.

Embedded C/C++ firmware development toolbox: agents and skills covering FreeRTOS, interrupts, NVM storage, Keil MDK, ARMCLANG, HardFault triage, state machines, architecture, and LVGL patterns.

Full-duplex voice mode for the DeepSeek Harness Web UI: toggle (2s-pause auto-send) or hold-to-talk dictation into an editable draft with zipformer2 streaming ASR, optional wake word; sentence-by-sentence Edge TTS read-aloud with live captions, and speaking interrupts playback and the running turn (true barge-in). On-device ASR, no API key.

A polished floating whale desktop pet for the DeepSeek Harness Web UI with 95 categorized transparent animations, state-aware event reactions, customizable actions and triggers, click interactions, dragging and screen wandering.

Offline-first UI/UX design intelligence library for DeepSeek Harness: design_recommend, design_review and design_search tools with a built-in database of 84 design styles, 192 color palettes, 74 font pairings, 99 UX guidelines, 25 chart types and 22 tech stacks, Chinese-first with zero runtime dependencies.

Adds an optimize button beside the composer that analyzes and rewrites the prompt draft with SSE streaming, conversation-context awareness (template vs intent-polish strategies), an edit-continuity memory chain, undo, and model routing with fallback and a connectivity test.

Access the dsh web UI over LAN: HTTP/HTTPS/WS forwarding plus TLS (self-signed or custom certificates); adaptive Brotli/gzip compression for HTTP and permessage-deflate for WebSocket; half-open WebSocket probing keeps mobile clients from going stale after backgrounding; launch-token auto-injection lets LAN devices connect without copying the token; DNS-rebinding protection + loopback-only upstream allowlist. Retired by the author: published npm versions stay installable but receive no further DSH adaptations (migration guide: docs/migrations/dsh-lan-proxy.md in the repository).

Task-event notification center: 6 event kinds (ask / approval / completion / subagent completion / error / turn end), dual channels (browser Notification + host system toast) plus Bark/Webhook push channels (ntfy, Gotify, self-hosted gateways); quiet hours with urgent exceptions, approval-timeout re-reminders, completion-storm aggregation, and notification text redaction.

Installs a multi-agent novel-writing preset for DeepSeek Harness: one conductor agent dispatches five specialized subagents — world-building, plotting, character management, prose writing, and QA review.

MCP server manager (stdio / streamable-http): per-working-directory project and global config tiers; project-level MCP collapsed into 4 atomic tools through a middleware layer by default (`middleware: all` folds in global servers too, hot-switchable in the settings page); workspace isolation prevents cross-project interference; configs keep `${ENV}` references only, with no plaintext secrets on disk; runtime registration API for other plugins to inject MCP servers.

File-based cross-session memory: plain Markdown memory files with automatic retrieval injection, format-compatible with Claude Code's CLAUDE.md and memory files, so migrating is a manual file copy.

Four-source migration wizard: move Claude Code, Codex, OpenCode and Hermes sessions, memories, skills, instructions and slash commands into DSH (/move wizard with approval gate and idempotent move.json, resumable sessions).

Play Gomoku against the AI, or let two AIs battle it out.

Notifications for four session states, with browser alerts and prompts.

GitHub-style usage heatmap dashboard: per-workspace turn counts and token spend (with cache-hit rate), DeepSeek account balance, and workspace aliases.

Registers the fnOS CLI Skill and provides a matching CLI for fnOS device operations. For first sign-in, the user authorizes access in a browser and sends a one-time code back to the Agent; no interactive terminal is required.

Ported from the ARS Claude Code plugin (44k+ stars on GitHub): academic research skills for DeepSeek Harness — a deep-research agent team, a paper-writing pipeline, a multi-perspective peer-review panel, and an end-to-end orchestrator, plus sixteen /ars-* commands.
