Reusable subagent definitions managed from a Settings page and dispatched through a single delegate_agent tool; ships with a built-in read-only Explorer preset and a nested-delegation policy toggle.

Durable DAG workflows for DeepSeek Harness with Agent authoring tools, SQLite persistence, resumable runs, and a visual Canvas Studio.

Claim-verification skill that checks design documents and plans against codebase facts, escalating behavioral claims to executable logic-primitive verification with structural checks and adversarial probes.

Embedded C/C++ firmware development toolbox: agents and skills covering FreeRTOS, interrupts, NVM storage, Keil MDK, ARMCLANG, HardFault triage, state machines, architecture, and LVGL patterns.

A document preview / edit / management plugin for DeepSeek Harness. It provides a VSCode-style "Document Center" workbench inside the DSH Web GUI: a file tree on the left, click-to-preview, editable code & Markdown with Ctrl/Cmd+S save; and exposes three document tools (doc_read / doc_edit / doc_create) to agents, letting models read and write workspace documents through natural language.

An Obsidian-style knowledge base: ingest sources, let the LLM build and maintain an interlinked wiki, and ask questions grounded in it.

Port of ponytail: an always-on lazy-senior-developer coding persona with intensity levels, persistence of the default level, and review, audit, debt, gain and help skills for DeepSeek Harness.

Paste non-image files or folders into the chat composer as native @path references, or drag them in as absolute paths, instead of the images-only error.

Task panel for the DSH Web sidebar: publish tasks, auto-distill related sessions, and drive plan/develop/review stages with subagents plus in-panel acceptance.

Native side-by-side chat beside the main conversation: an independent archived DSH session with full native UI, on-demand parent-context retrieval, selection quoting, and a keep-or-delete lifecycle.

Profile-aware keyboard shortcuts for DSH Web: supports Question and Approval cards, Standard/Vim/Custom profiles, and capability-gated Session and Workspace navigation.

Sidebar session-title icons: an auxiliary model call on the same route as title generation draws a 24x24 monochrome SVG metaphor shown before each session row title, with disk caching.

Web GUI convenience suite with appearance controls, timeline navigation, project folders, prompts, conversation export, Mermaid rendering, quote reply, and DeepSeek balance and daily token usage.

Dockable DSH Web UI layout that organizes conversations as tabs across draggable split groups.

Deterministic data profiling, cleaning, and verification: data_profile / data_clean / data_verify tools plus a frozen cross-plugin verifyCitations citation-checking contract, with durable reports in a storage domain.

LLM auto-review approval answerer for sandbox escalations under the `'auto'` policy: a deterministic filter plus a clean-context reviewer model decide without a human prompt, fail-closed on every error path; requires a patched harness core (included in core-patches/).

Named credential manager: the model uses API keys, tokens, and logins by reference; secret values are injected into each shell run as `DSH_CM_*` env vars, resolved per execution, and never enter the conversation.

Per-session Web Search toggle that directs the agent to search the web before answering.

Per-round cache billing inside the composer context-meter popover: what the current call spends on cache hits, misses, and output in CNY, with automatic official peak/off-peak and per-model pricing; hidden on non-official DeepSeek routes.

Free web search with 10 engines (Bing/DuckDuckGo/SearXNG/AnySearch free + Exa/Tavily/Keenable/Perplexity/DeepSeek paid), automatic fallback chain, time-filtered advanced search, platform search (GitHub/Reddit), web page fetching, LRU caching, and a settings UI. No API keys required for basic use.
