Plugins

Renders assistant replies with numbered citation chips and a sources panel for web-search results, inline pictures with their source captions, and KaTeX formulas, Mermaid diagrams and highlighted code in streaming Markdown.

Markdown conversation theme plugin — 4 built-in themes with light and dark variants, user-editable CSS themes, system-aware auto-switching, an in-browser editor with syntax highlighting and save-time validation, and a theme selection that persists across reloads and tabs. Also ships a version-history panel. Windows and DSH Desktop supported.

Renders every file mutation in the web chat as one collapsed diff card with per-line highlighting — MCP filesystem edit_file/write_file and the built-in edit/write.

Adds selection quoting and anchored annotations to DSH conversations: selected text enters the composer as an anchored quote reference, a quote bar jumps back to the source message and highlights it, and the sent quote block names the turn and role it came from.

Paper reading workbench: a paper library, the PDF beside Markdown notes and one dedicated AI session per paper. Highlights and region screenshots go straight into notes; select-to-ask sends the passage with its page; notes are editable in place with autosave; sessions can be combined into a Summary.

Select text in the dsh web conversation to attach it as an annotation to your next message. The source text keeps a dashed highlight with an ordinal badge in place, and the composer summary lists, edits and jumps back to each annotation.

In-chat preview for produced files: click a produced-file chip to render Markdown (server-side markdown-it + highlight.js), images, or plain text right in the conversation; system-app open and reveal-in-folder stay one click away.

Feynman learning-mode plugin: teach → teach-back → judge → re-explain loop rendered as rich HTML lesson cards (mermaid diagrams + shiki code highlighting).

Code workbench in the right sidebar: a workspace file tree and a multi-tab Monaco editor with syntax highlighting and version-guarded saving, Tab completion from DeepSeek fill-in-the-middle, per-save checkpoints with rollback, codebase search (plus a codebase_search tool for the agent), and reference chips that insert a selection into the chat as an @path mention.

Your real Obsidian vault in the DSH right Sidebar: vault tree, full-vault search, read-view typography, wikilinks and heading anchors, properties, backlinks, highlights, in-place editing, an outline, and a right-click menu for handoff, rename and .trash.

One-click standalone two-column code review page for Git diffs in the conversation: line numbers, add/delete coloring, character-level highlight, hunk-aware per-file sections, a file nav sidebar and a stats bar; line comments submit back to the DSH composer, and the UI follows the DSH locale.

ChatGPT-style question nav rail with up/down arrow buttons — per-question tick marks on the chat edge, hover-triggered drawer listing every user question with real-time search filter, one-click smooth-scroll jump, and active-question highlight synced to scroll position.

Renders edit and write tool calls as always-expanded side-by-side diffs styled like git diff, with optional syntax coloring and word-level highlighting.

Signature escook theme ported from VS Code: 4 classic aesthetic color schemes (Dark, Dark Soft, Light, Light Soft) with high-contrast syntax highlighting for DeepSeek Harness.

Windows desktop UI context picker for Codex, DeepSeek Harness, and MCP clients: select windows, UI elements, or screen regions with hover highlighting, UI Automation, screenshots, and local OCR, then review and approve Markdown/JSON context before output.

File-change monitor and code editor for the DSH Web UI. Agent edits appear beside your conversation as real-time line-by-line diffs, with a syntax-highlighted editor, one-click revert, change history, workspace switcher, and per-session isolation.

Code preview for dsh-better-sidebar with per-language syntax highlighting, symbol outline, in-file search, and selection-to-conversation.

Browser-style in-page find bar (Cmd/Ctrl+F) for the desktop app, with highlight-all, a match counter, and a scope picker for the conversation or the right panel.

Select text in a conversation to attach a numbered highlight with a colour stored per note, keep every mark in an outline panel that jumps back to its quote, and let a corner self-check badge report style, selector and saved-key problems without opening dev tools.

Change review for a turn's edited files: a pill above the composer counts this turn's files and lines and floats the file list up on hover, and a right-sidebar page shows each file's diff with syntax highlighting and a one-click revert.

Pins a selected passage of a finished user or assistant message as source text and keeps it in the model input across context compaction: each pin is recall-on-demand by default, or can be moved to a neutral resident system-prompt section or an emphasised highlighted one. Selections are aligned back to the source text with source-exact, source-normalized or rendered fidelity, and each of the three levels has its own character budget.

Native right-sidebar Markdown preview with Mermaid diagrams, KaTeX math, GFM tables and syntax highlighting — rendering engine bundled, fully offline.

Select text in a reply and quote it into the composer as an atomic reference chip: delete the whole chip in one keystroke, click it to scroll back and highlight the quoted turn, and expand it into a bounded reference block at send time so the model can tell the quote apart from what the user typed. Also opens the snippet in a side chat, or copies it to the clipboard.

Renders Jupyter notebooks in the document preview, with syntax-highlighted code, offline KaTeX for inline and display math, and a zoomable figure viewer.
