Inspired by ChatGPT's "Ask ChatGPT" selection popover: select any text in a conversation reply — one line or many — and a floating ❝ 引用 (Quote) button appears above the selection's first line. Click it and the selection lands in the composer as a Markdown blockquote, with the caret ready on the line right below. Type your follow-up question immediately.

Features

• Floating quote button — appears on selection over conversation text; hides on scroll, resize, or clicking elsewhere
• Clean Markdown output — one > per line; multi-line selections carry proper > continuation lines and render as a standard blockquote after sending
• Chained quotes — quoting again appends a new block separated by exactly one blank line, handy for asking about several passages at once
• Writes through the front door — inserts via inputActions.setDraft, the input machine's single public write path, so undo history, reference chips, and draft stats all keep working
• Follows the app language — the button label renders through DSH's locale service: 「引用」 on a Chinese UI, "Quote" on an English one
• Zero dependencies, zero build — plain JavaScript shipped as-is; installing from GitHub runs no code and needs no pnpm allowBuilds permission

Install

# From GitHub (pinning to a tag or commit is recommended)
dsh plugin --profile web add github:lianginx/dsh-quote-selection
# Or locked:
dsh plugin --profile web add github:lianginx/dsh-quote-selection#v0.1.0

dsh --profile web   # or: dsh web

Local development install (with this checkout kept next to deepseek-harness):

dsh plugin --profile web add ../dsh-quote-selection

add links the checkout (link: semantics), so editing client.js takes effect after restarting dsh web — no reinstall needed.

Requires node ^22.19 || >=24 and a profile containing the official @deepseek-ai/dsh-web-app layer (the shipped web template has it).

Usage

1. Select some text in any assistant reply;

2. Click the floating ❝ 引用 button;

3. The composer now holds:

   > The quoted first line
   >
   > The second line
   

   with the caret on the line below — start typing your question;

4. Select other text and quote again: the new block joins with exactly one blank line between quotes.

Uninstall / upgrade

dsh plugin --profile web remove dsh-quote-selection
dsh plugin --profile web update dsh-quote-selection

How it works

Piece	Slot / mechanism
Floating button	shell.overlay (additive list slot, click-through by default); selection validated against the product anchors [data-conversation-scroll] / [data-composer-seat]
Draft write	An invisible bridge component on conversation.composer.dock holding inputActions.setDraft — the input machine's only public write path
Styling	A data-plugin-tagged stylesheet injected inside the factory closure, built on theme tokens (--dsw-alias-*) so light and dark both adapt
Timers	The Cordis timer service (inject: ['timer']); no native timer globals
Copy	A plugin-private locale namespace registered through the Cordis locale service (zh/en, English fallback)

The browser half depends only on baseline module-table entries (react) and Cordis services (slots, timer) — no other @deepseek-ai/* value imports. The package follows the DSH publishing conventions (publish tutorial): manifest dual declaration dsh.bundle.patch + dsh.client { platform: 'web' }, and a patch that only inserts rows.
