Tools & Capabilities

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.

Per-agent on-demand tool discovery and progressive schema disclosure.

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

Bring your existing Agent Skills (SKILL.md) library to DSH: discover skills across Claude/Codex/Cursor/Gemini paths, inject a progressive-disclosure index, and load bodies on demand.

Build auditable KB packs (SQLite FTS5) from md/txt/docx/pdf with deterministic retrieval and original-text reading.

Codex-backed `web_search`, `image_gen`, and `image_vision` tools for DeepSeek Harness, reusing ChatGPT OAuth login state.

Native LLM-provider vision bridge: images pasted in the chat are described by a vision model (Qwen3-VL via pi-ai/llama.cpp) and the text description is fed to text-only DeepSeek for the reply — image admission, routing and compaction all run through harness-native mechanisms, with an LRU description cache and 503 retry.

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

Cooperative timeout guard for ask_user_question: lost or unanswered questions resolve as a structured ASK_TIMEOUT instead of hanging the turn forever.

Download progress panel: URL downloader, agent shell/SSH transfer tracking and workspace black-box file-growth monitoring, shown in a draggable floating panel with live bytes, speed, percentage and ETA.

Pin assistant replies from the Web action strip and recall them into the next model turn (`/pin` `/recall`, with optional wake).

Two-tier model router for DeepSeek Harness — LLM-Judge routing, multi-model fallback chains, exponential-backoff failover, and task-level orchestration (DSH adaptation of pi-shift-router)

Voice for DeepSeek Harness（dsh） — speech-to-text input + read-aloud TTS for text-only DeepSeek, zero API key.

DSHWeb 审批增强插件：无感替代内置审批窗口，支持「拒绝并附言」，并在拒绝后终止当前回合、让模型重新结合附言思考

DeepSeek Harness tools for finding and inspecting plugins in the dshhub catalog

DeepSeek Harness plugin: per-request thinking-mode switch (enable_thinking) for Qwen3-family models on OpenAI-compatible endpoints

DeepSeek Harness plugin: secondary working directories for a project. The agent keeps the primary workspace as cwd, gains equal write/exec permissions on configured secondary directories under workspace-write mode, and is notified of configuration changes

Git-aware write guard plugin for DeepSeek Harness: blocks whole-file writes that would overwrite the user's uncommitted changes, and reports what happened to protected files at turn end
