Plugins

DSH input assistant for next-message prediction, draft autocomplete (text completion), and prompt polishing/rewrite. Session-local suggestions; Tab accepts into the draft without sending. Requires a configured model; calls may incur charges. Source-available; modifications require prior written permission.

Typora-style Markdown editor for the DSH right sidebar: live math and Mermaid rendering, click right of an image to keep writing on the next line, Ctrl/Cmd+S with version-guarded saves that also work outside the session workspace, and selections inserted into chat with their absolute file path.

Terminal-style composer for the DSH web GUI: shell prompt history (↑/↓, prefix search, Ctrl+R), Codex-style completion and next-prompt prediction (Tab or → to accept), selection toolbar (copy / quote / ask in side chat), right-click paste, draggable chat TOC, and a parallel side-chat thread in the right sidebar.

Input prediction for the DSH composer: your next prompt suggested as ghost text after each turn, accepted with Tab. (autocomplete / input prediction / prompt suggestion)

Prompt optimization, next-sentence prediction, inline completion, and per-session draft stashing for the DSH input box.

Tab autocomplete for the DeepSeek Harness desktop and web composer: next-message ghost text, inline draft completion, and Alt+Up/Alt+Down candidate cycling.

DeepSeek Harness 输入框的下一句建议：助手回复完，空输入框里出现一句灰色建议，按 Tab 填入。Prompt suggestions for the DSH composer.

Input prediction for the DSH composer: your next prompt suggested as ghost text after each turn, accepted with Tab. (autocomplete / input prediction / prompt suggestion)

Input prediction: the likely continuation of your draft appears as grey ghost text after the caret and Tab accepts it, and after each assistant turn 1-3 clickable follow-up suggestions appear above the input box and send on click. Ghost completion, suggestions and the suggestion count can be toggled in Settings, Built-in plugins.

The composer predicts what you are about to type. Inline ghost text sits on the caret, measured against the editor's own font and line box, and Tab turns it into real text (Esc ignores it). The prediction is one short call through the session's own model router, seeded with your draft and the last few turns of the conversation, so an empty composer also gets a next-prompt guess written in the user's voice; suggestions that merely restate the assistant are dropped. Host side is one HTTP route with sub-path endpoints (loopback-only, 64 KB body cap, 2-minute result cache, 20-second miss cache, one in-flight call per session); client side is one 0-height overlay registered on conversation.input.overlay, with insertion guarded by the composer's draftRev CAS and a setDraft fallback. IME composition and slash commands are skipped. 16 node:test cases, zero runtime dependencies, real screenshots in docs/.

Predicts your next message after each completed turn and shows it as ghost text in the composer: press → to accept, or keep typing and finish it word by word with Ctrl+→, Esc to dismiss. The prediction model follows the session by default or can be picked in the settings card, which also has an on/off switch and a speed test.

Completes @path references in the Web composer: type @ (optionally ./src/ma) to list matching files and directories, pick one with the arrow keys, and the draft receives an @./relative/path reference (quoted when the path has spaces).
