SymPy-backed exact computation and independent verification for China's postgraduate entrance exam Mathematics I: 14 tools over 214 operators, exact symbolic results by default, and every result re-checked by a separate mechanism (requires Python 3.10+ with sympy and mpmath).

Config-only DeepSeek Harness bundle that mounts the in-box MCP client bridge against CursorTouch/Windows-MCP, excluding PowerShell, FileSystem, Registry, Process and Scrape by default (16 of the 21 tools upstream 0.8.8 publishes). Requires uv on PATH.

Runs a Claude Code project's .claude/ slash commands and permissions.deny rules inside DeepSeek Harness. Command bodies expand $ARGUMENTS, positional arguments and @file references into the agent's next turn; matching tool calls are denied before they run. Every host service is probed, so a host without a command registry, working-directory service or TUI status line degrades one feature instead of failing the boot.

Requires Python 3.12+; Xiaohongshu reading needs the xiaohongshu-mcp backend and a QR sign-in (ffmpeg/OCR optional). Batch-read Xiaohongshu notes and WeChat public-account articles: per-note body, image text via local OCR, video frame text and comment samples, structured JSON/Markdown output, and the original source URL on every result. Read-only: it never publishes, likes, follows or comments.

Run the local Cursor CLI agent on a coding task in a workspace and continue the run by chat id.

Read Bilibili and Douyin from a session: WBI-signed Bilibili API calls behind one shared pacer (4 req/s, per-host cooldown after a 412) for video, feed, search, author, comments, danmaku and subtitles, plus Douyin hot list, video, feed and search rendered in a locally launched Edge over CDP.

System One decision runtime for dsh. Ships fast non-generative tools (choice, score, screen, gate) on a local or hosted System One gateway, and — without the model calling anything — prunes oversized tool output segment by segment, refuses repeated identical calls once System One confirms stagnation, verifies completion claims against real tool evidence, and corrects failing retries. Published on npm as dsh-harness-reflex (plugin) and harness-reflex (core, also a stdio MCP server).

macOS cross-application desktop tools for DSH using CuaDriver, with a hidden agent cursor, background window selection and post-action observations.

Genspark tools for DeepSeek Harness - web search, crawl, image/video/audio generation, media analysis, X/Instagram/Reddit search and model listing through @genspark/cli, with 17 typed tools and 18 /genspark-* commands. Requires @genspark/cli installed and logged in (gsk login), or GSK_API_KEY set.

Prompt enhancement: click the star button in the composer to have the current model rewrite the draft more clearly, with one click back to the original; the template is editable.

Exposes a stdio MCP server as native DeepSeek Harness tools. Ships with the official Microsoft Playwright MCP preset, so the agent browses through the Edge or Chrome you already have open, with your logins intact; any other stdio MCP command can be configured instead. Host-only, no client bundle, no npm dependencies. To drive your own browser, start Edge/Chrome with remote debugging and allow npx to fetch @playwright/mcp.

AI research toolkit for DSH: a model release radar, a per-model benchmark and community report from 13 structured leaderboards plus Chinese and English community discussion, and an AI news radar over 46 feeds and 22 official X accounts; registers four tools and three skills and renders every report to Markdown with a generated table of contents.

Adds extra working directories to a workspace, each read-write or read-only, from a folder button next to the composer or the `/add-dir`, `/remove-dir` and `/dirs` commands; the model sees them in its runtime context, and `write` and `edit` calls into read-write directories skip the sandbox escalation prompt by default while shell commands still ask.

Bridges the Cua Driver MCP server into DSH: installs the cua-driver executable when it is missing, starts it over stdio through the in-box MCP client, and registers its 60 accessibility-first window, input, menu, and browser tools with a bundled workflow skill and one-time macOS permission guidance.

Translates user prompts before sending and translates model reasoning and replies back into the user's language via translation APIs or configured DSH models, with independent content toggles and a composer menu.

Six RF calculators as agent tools: level conversion, link budget and maximum range, cascade noise figure, Shannon capacity, and impedance match.

One switch that takes an MCP server's tool schemas and its instructions block out of the model context for every agent, live and without a restart, built for the 207 tool schemas REA registers whether or not a task is reverse engineering. A pill in the composer dock, /rea on|off|status|toggle, and GET/POST /rea-toggle/state; the position is remembered across restarts and subagents are covered before their first step.

Read, edit, export and verify Excel VBA projects through a real Excel COM instance: modules, UserForm code, procedure lists and .frm/.frx exports. Windows only, with desktop Excel installed, Python 3.10+ with pywin32, and AccessVBOM=1.

Ship a local DSH plugin project to GitHub and the plugin market in one call: preflight, per-file upload with byte verification, the market registry PR, then pull every published file back and compare bytes.

Release gate for AI answer quality. Two channels: replay an existing VeriScope archive through the original Python quality gate, or run a threshold gate over a Ragas per-row export with Node only — no VeriScope, Python or pandas. Returns PASS, FAIL or REVIEW with source evidence and a re-checkable receipt; supports per-row thresholds and exact decimal comparison. It never re-evaluates and never calls a model, and REVIEW never becomes PASS.

Notes-backed context compression for DeepSeek Harness: replaces LLM-summarized compaction with a model-written persistent notebook plus recoverable raw history, so the rollover boundary itself costs zero model calls.

Archives the QQ Zone posts you published yourself into a local library, auto-sorted into three columns — thoughts, dreams and reviews (book/film recommendations) — all three of which can be corrected by hand, one column at a time, and undoing a correction never disturbs the other two. Ships a private web viewer that can be locked with a password, repairs long posts that the upstream API truncates to its first ~500 characters, counts words by year and month, and backs up attached images for offline reading. The cookie is stored on the local machine only.

Runs the upstream Headroom compression toolkit (headroom-ai, Apache-2.0) inside DeepSeek Harness over MCP: headroom_compress, headroom_retrieve and headroom_stats are exposed as mcp__headroom__* tools backed by the upstream server, installed on demand by uvx. Compression is lossy but reversible — originals are fetched back by hash from a local CCR store. Also ships a registrar that adds DeepSeek Harness to Headroom's own MCP registry, and a model-header sanitizer for the upstream proxy.

Registers the Akasha Book memory server over stdio and exposes its 22 akasha_* tools to DeepSeek Harness, covering lookup, briefs, revision chains, audits and session recall. Companions: Hindsight (repo memory), OpenViking (user memory), and the built-in session search (see repo README). Setup: clone the repo, copy core/ aside, then replace <AKASHA_DIR> in cordis.patch.yml with its absolute path (or set the AKASHA_DIR env var); plugins fail loudly while the placeholder remains.
