HarmonyOS device bridge: hdc screenshot/install/log/crash/UI automation loop with read_image, official-first versioned API knowledge (SDK .d.ts + offline bundled docs), and a DevEco CLI build/sign/lint lane.

Academic writing guard (EN/ZH bilingual rules): local-regex linter for revision-process residue, defensive writing and AI-writing tells (em-dash abuse, not-X-but-Y, LLM word spikes, rule of three); writing_audit + writing_rules with incremental auto-audit that only reports new/resolved issues on paper file writes.

Add a WSL workspace from the web GUI without needing to install dsh or related tools again inside WSL. Bash commands and file read/write operations run within the local WSL distribution on the host machine, while Windows files remain accessible.

Connect multiple Overleaf projects to DSH through OverleafMCP for browsing, analysis, and Git-based file updates.

US stock quotes, price history, financial statements, analyst consensus and news via yahoo-finance2.

DSH↔Godot engine runtime bridge: launch and drive a running Godot 4.x game through its in-game TCP interaction server — 8 tools (scene/UI inspection, GDScript eval, input simulation, screenshots, headless static ops, script validation), replaces godot-mcp.

Safe math expression evaluator, zero-dependency recursive-descent parser.

A web-novel writing engine for DeepSeek Harness: parallel drafting, outlining and brainstorming with a separate DeepSeek key, lore and foreshadowing management, semantic vector retrieval, a corpus library, usage ledger, mechanical proofreading, and a local serialization plan.

Free, keyless web search for DSH: 7 engines (DuckDuckGo/Bing/SearXNG free + Exa/Perplexity/DeepSeek paid), auto-failover, settings-page UI with API key inputs and official links, web_fetch, and an engine test tool.

Bridge plugin for the [Better DeepSeek](https://github.com/EdgeTypE/better-deepseek) Chrome extension: exposes HTTP handshake and session-filtered SSE event streams over the web server, enabling browser-extension UI integrations with DeepSeek Harness.

Batch-port official Codex plugins into DSH skills (measured: 186 plugins / 583 skills, 577 ported, 0 failures).

IMAP/SMTP email tools (list/read/search/send/folders/attachment) with QQ/163/126/Sina/Aliyun/Gmail/Outlook/iCloud presets, multi-account support and a send-approval gate.

Zero-config Exa web search provider for the ctx.web seam: anonymous MCP fallback without an API key, plus keyed REST search.

Talk to Excel in DeepSeek Harness: create, edit, repair, and verify spreadsheets by conversation, with automatic formula health checks after every edit.

Descriptive statistics, percentiles, frequency distributions, and correlation.

Shared real browser for DSH: a native Electron window the human can watch and take over, driven by the agent over CDP with 20 browser_* tools (open/snapshot/execute/fill/screenshot/download/auth), per-task session isolation, cookie persistence, CAPTCHA detection; self-hosts on plain dsh web without a desktop shell.

HeartFlow (心虫) AGI layer-1 discriminator gate as a DSH plugin: 47-dimension rule-based text checking (heartflow_check tool) plus automatic output supervision at tools/post-execute, fail-closed when engine missing.

Secondary working directories for a DSH project: the agent keeps the primary workspace as cwd and gains equal read/write/exec permissions on configured secondary directories, configurable from the session header and the new-session page.

Fine-grained permission gateway: per-category tool-call review (outside-workspace directories, commands, file read/write, subagents, repeated actions) with global & per-project allow/deny exceptions, quick-tool defaults, custom rules, a bilingual approval modal with inline diff details, custom rejection reasons and a sandbox-upgrade flow.

LSP action surface for DSH: diagnostics, formatting, completion, code actions, symbols, signature help, inlay hints and rename, all backed by real language servers.

Upload local images and files to your image host through PicGo's existing configuration (PicGo Cloud, GitHub, S3, COS, Qiniu, or any installed uploader plugin), via a `picgo_upload` tool and a `/picgo` command.

Hash-anchored read / edit / batch_edit / undo_last_edit tools: every line gets a unique 3-character content hash, edits target hashes instead of line numbers, and served-state verification rejects stale ranges with fresh anchors.

Let agents search, read, and cite your local Zotero library: find papers, view notes and annotations, pull evidence by question, open the source document, and generate citations.

Session execution analytics: steps, tool calls, failures, repeated actions, token usage and verification signals, rendered as text/Markdown/JSON reports.
