Plugins

Automated unit-test generation: a /testgen command and generate_tests tool that scaffold, run, and fix tests until they pass (LLM + offline template generators; vitest/jest/mocha/node:test).

Evidence-first operating kit: six read-only tools (capability catalog, staged workflow plans, packaged skill reader, bounded local memory search, repository release audit, release checklist) and five packaged skills - plans and audits, never remote writes.

Native Search1API (s1) web research tools: search, news, page crawling, sitemap discovery, and trending topics as first-class `s1_*` tools, with a bundled s1 skill.

Traditional Chinese Medicine toolkit: eight-axes diagnosis and herb-pair lookup.

Real-compute verification gates: math simplification, logic proofs, regex validation, E-prover FOL, state-machine checks, and code repair, backed by Go-compiled binaries with prebuilt Windows executables.

Multi-engine reverse image search aggregator: Google Lens, Baidu, Yandex, TinEye, SauceNAO, IQDB, Ascii2d.

Extends dsh-subagent-tools with a per-call cwd for subagents, shipped with the two in-process provider patches it requires.

Per-call model, provider, persona, and toolFilter overrides for subagent delegation, with @preset: references and provider/model composite ids.

Update manager for installed plugins: check for updates, back up, and roll back.

Plugin center: discover, install, and manage DSH plugins from Settings.

Project .pack.json/.pack.zip into .agent-pack/modpacks/ and expose skills via a workspace allow-list.

Composer-attached images are transcribed to text by an OpenAI-compatible vision model before reaching text-only DeepSeek models.

Bounded, privacy-safe local scanner for Codex, Claude Code, WorkBuddy, and CodeBuddy metadata: atomically aggregates keyed evidence and deterministically advises built-in DSH presets and optional capabilities—without content retention, network access, or preset mutation.

BM25 keyword-based memory recall.

Project-scoped cross-session memory: PROJECT.md snapshot injected into the first user message, a memory_remember tool, and auto-reflection after ReAct tasks; each project keeps its own memory file.

Bounded local memory with CBDC authority gating: SQLite + FTS5 claims, scoped recall with explainable use/verify/ignore decisions and a full audit trail, /memory commands, ≤3-claim/1200-char injection per call, no extra model call.

Local, per-session LIFO prompt stash for temporarily setting aside unfinished composer text and safely restoring it later.

Cross-session task queue with handoff notes: sessions and subagents push, claim, complete and cancel tasks on a shared file-backed queue, and leave a handoff summary for whoever picks up next.

Windows tray desktop shell for DSH: auto-installs the exe from GitHub Releases, creates a desktop shortcut, and adds a desktop_launch tool to start it from chat.

One-click collapse of every expanded section (Think rows, tool cards) with a live-count pill and a customizable hotkey.

Collapsible iOS-style stats pill under the composer: session cost, DeepSeek account balance, cache-hit rate, and token usage in a frosted panel.

Region screenshot for the composer on Windows: a full-virtual-screen selector frames the region (drag the frame, eight grips, Ctrl+drag to annotate), and the finished PNG lands in the composer as a pending attachment.

Opens chat.deepseek.com in the right sidebar pane from one row in the left sidebar, leaves the current conversation untouched, expands to fullscreen on demand, and shares the sidebar browser cookie jar; a bundled script makes the login survive restarts. Desktop (Electron) only; keeping the login across restarts needs the bundled PowerShell patch, which is Windows-only and must be re-applied after every DSH upgrade.

Windows computer use for DeepSeek Harness: consented screen takeover with an interactive mask chat panel, plus screenshots, mouse, keyboard, windows and clipboard through a native helper.
