Plugins

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

JSON Schema validation: validate/paths/explain/normalize.

Test/extract/safe-replace/statically explain regexes without executing code.

HTML↔Markdown conversion, GFM table normalization, and TOC generation.

JSON queries with a JMESPath subset.

HeartFlow (心虫) AGI layer-1 discriminator gate as a DSH plugin: 47-dimension rule-based text checking (heartflow_check tool) plus automatic output supervision at tools/post-execute, fail-closed when engine missing.

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.

Vector + graph memory backend: observe/remember/search/recall tools against a local memoria server, fusing HNSW semantic recall, FTS5 keyword search, and knowledge-graph signals via RRF ranking, with automatic turn-end persistence and per-agent namespace isolation.

Export the current session to portable, schema-versioned Markdown and JSON files via the `session_export` tool and slash commands, with cross-platform-safe filenames.

Render local image paths from assistant replies inline in the message body (9 formats, click-to-zoom lightbox, adjustable size).

Microphone voice input for the composer: browser Web Speech API live transcription, dedupe/auto-continue, smart punctuation, language and auto-send settings.

Desktop pet for the DSH Web UI: sprite-sheet animation, agent state linkage, drag, alarm (daily/one-shot) and pomodoro widgets, skin picker with preview.

Audio/video FileViewer for dsh-better-sidebar: native inline playback for mp4/webm/mkv/mov and mp3/flac/wav, served by a Range-capable streaming media route.

Deep links: open a specific session or workspace via `?session=` / `?workspace=`.

Upload arbitrary local files from the Web composer, show pending cards, and manage stored files in Settings.

Search and insert workspace file and directory paths with `@`, plus a `/h` menu for reusing prompts from the current session.

The generic New Session action opens a default-directory workspace instead of requiring a folder pick, and the workspace picker lists that workspace as a no-folder choice.

Niubash-only shell executor and Bash-dialect teaching for DeepSeek Harness (dsh 0.2.0-rc.2, and the 0.1.7-rc.x line it shares its shell seam with): every ctx.shell execution runs as `niu -c`, PowerShell/cmd/WSL/nu handoffs are refused, PowerShell habits a
