Plugins

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.

Text-first computer use for DSH: background Chromium control via Playwright/CDP plus accessibility-first macOS control; actions stay pinned to the right process and window without taking the user's pointer, ships a Developer ID signed, notarized Universal 2 DMG.

File upload with color-coded attachment cards (session-isolated storage, sha256 dedup, TTL sweep) plus a content-sniffing read_document tool for PDF/DOCX/XLSX/TXT.

Permanently delete DSH conversations with optional recursive deletion of forked and subagent sessions.

Controls your real Chrome from DSH over a local WebSocket bridge: tab management, navigation, DOM snapshots, page JS evaluation, clicks, typing, screenshots, waits and dialog handling behind a Settings toggle.

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.

Feishu/Lark bridge for DeepSeek Harness: scan-to-connect PersonalAgent binding, streaming cards, git-worktree project workspaces, parallel per-scope tasks, multi-role agents, cross-session notify, in-chat model/key management, and a safety-net guardian that still answers in Feishu after dsh crashes.

One-command backup, restore & migration for all DSH user data (~/.dsh) with a visual Settings panel: scheduled auto-backup with tiered retention, sha256 verification, hardened restore with auto-rollback and a result receipt, typed sub-backups (--types), credential redaction into a local vault, private-repo GitHub sync for moving to a new machine, and an out-of-process rescue console (zero-dependency rescue web UI in the backup dir) that works even when the host won't boot. /backup doctor checks and repairs corrupt session logs from a known-good backup and quarantines them before rotation; migrate-check statically predicts which sessions a host upgrade would break (frozen event-list rules, filename/generation mismatch, hardlink support, legacy credentials); the credential sentinel preserves pre-migration copies before the host rewrites them; smart backup snapshots before host upgrades; /backup check-update and /backup update report and install new releases (snapshotting first). Restore handles attachment hard links and arbitrarily large archives (streamed listing). Current npm version 0.13.4; spans DSH 0.1.1-rc.2 through 0.2.0-rc.1, including 0.2.0's install-time peer gate. macOS/Linux/Windows.

Dual-brain Chrome automation: registers the browserpaw skill and browserpaw_session tool to connect with the local BrowserPaw host (127.0.0.1:12306 via bridge-token), driving Chrome without losing logins.

SkillRoute by JEStats: skill routing for DeepSeek Harness agents.

Minecraft development for DeepSeek Harness (dsh), covering Minecraft 1.7.10 through 26.3: 9 skills for Paper/Spigot plugins, Fabric, Forge and NeoForge mods, addon development against major mods, and Gradle/JDK setup per era; the mc_scaffold generator and mc_gradle runner; 18 offline API signature indexes generated from the pinned artefacts with provenance headers; and mc_arbitrate, a deterministic sharded pipeline (contract freeze, per-shard briefs, 21 high-confidence audit rules including 5 cross-shard checks, manifest merge, compile-error routing) that calls no model inside the engine. Apache-2.0 with NOTICE.

Unified multi-provider web search and fetch: BYOK key pools, health monitoring, and deterministic fallback.

Multi-agent workflow for math-modeling contests: the "UltraMath" preset runs a problem from reading through framework, derivation, coding, verification, paper and review, plus 4 single-stage role presets (mathematician, engineer, writer, reviewer) and 33 model-library skill docs.

Research-only trading workbench bundle: typed market-data provider seam with a CSV reference provider, multi-timeframe indicator regime snapshot and OHLCV tools, interactive chart cards in dsh web with provenance-gated model annotations, and a risk-guard denying execution-shaped tool calls at tools/pre-execute.

In-GUI skill hub for DeepSeek Harness: browse, search, toggle, inspect, diagnose and scaffold local skills from the official ctx.skills registry, plus a skill market with tracked source sync and one-click update-all. It uses the same package name (dsh-skill-hub) and mount id (skill-hub) as hoshino114/dsh-skill-hub and amd47802574/dsh-skill-hub, so only one of the three can be installed.

Manage soul.md persona cards and long-term memory, with workspace and session persona selection and tools to read and update them.

Cross-instance message and event handoff between DSH instances via an interconnect server.

LAN/remote access for the Web UI: injects a crypto.randomUUID polyfill on plain-HTTP origins so the frontend survives LAN or Tailscale IP direct links.

Deep PTC mode is an open-source agent preset for DeepSeek Harness that keeps the built-in PTC tool surface and replaces the persona with a working contract: a DeepSeek identity and unlimited-token-budget instruction so the model does not skip reads, commands or checks to save tokens; planning by estimated size (internal up to 5 minutes, shown without approval up to 20, approval required beyond); and asking about unclear intent instead of guessing. Waiting is limited in code by wrapping the official shell, job and question tools: foreground commands move to background jobs after 30 s (configurable), a steered user message ends the current wait so the model reads it, foreground pauses over 5 s and long timers in run_code are refused, and questions run in timed mode. The mode derives its preset from the official PTC declaration shipped by the installed Harness and inherits upstream composition changes, so an official PTC update — including removed or renamed modules — does not break existing sessions. A settings card selects the preset executor — Automatic, WSL Bash, Windows PowerShell, native Zsh or native Bash.

One-click prompt enhancement in the composer — rewrites the draft into a structured prompt (role and goal, executable steps, output format, acceptance criteria, edge cases) with before/after preview, fill-back, and undo. Never changes intent, never fabricates requirements.

Runs scheduled coding tasks in isolated DeepSeek Harness sessions, managed from Settings or the agent.

Douyin assistant plugin: picks a daily round of videos, reads comments, writes a dated report, can like and comment with an @ mention (both off by default), and publishes clips rendered by your own ComfyUI. Windows only; needs Python 3 and a system Chrome, and the first run needs the install-main-dependencies step plus a QR-code login.

Reflective self-evolution plugin for local Qwen3.8 27B/3.8 Flash and online APIs: a coding-loop convergence steerer curbs Qwen3.8 27B/Flash repeated-verification deep-thinking to converge faster and cut thinking time; a five-state delivery guard detects and corrects stuck turns and infinite loops; model-agnostic host logic, mostly compatible with online APIs; per-use continual self-improvement with counter-reason self-checks, critic escalation, inverted-index memory retrieval, coding-loop convergence steering, and a five-state delivery guard.
