dsh-addtochat

Select text inside a conversation reply and add it to the composer input as a fenced code block — one button replaces select → copy → paste.

![interaction: select a reply → floating button "添加到会话" / "add to chat" appears above the selection → click → the selection is appended to the main input as a ``` block → type your question → Enter]

What it does

1. Select any text inside a conversation message (not streaming).
2. A small floating button appears above the selection:
   • Chinese UI: 添加到会话
   • anything else: add to chat
3. Click it: the selected text lands in the main composer wrapped in a fenced code block (``` on its own lines), followed by a blank line — anything you already typed stays above it, and your next keystroke starts right below the fence.
4. Type your question and hit Enter — the block rides along with your normal submission.

That is the whole feature. No badges, no bubbles, no persistence, no reply tracking. The plugin does exactly what the button says: moves the selected text into your input so you can ask about it.

Zero-hack contract

• Selection capture: browser-native selectionchange / getSelection().
• Composer write: the OFFICIAL inputActions.setDraft face that ui-conversation injects into conversation.input.dock slot entries (standard-props), bridged to the plugin's own overlay host.
• No renderer replacement, no session.prompt monkey-patching, no composer DOM interception, no localStorage, no sending logic — the plugin never submits anything; your Enter does.

Install

dsh plugin --profile web add dsh-addtochat

or, from a local checkout, link it into the profile package:

"dependencies": { "dsh-addtochat": "link:/path/to/dsh-addtochat" },
"dsh": { "profile": { "bundles": [ ..., "dsh-addtochat" ] } }

then restart the web app.

Build & test

pnpm install
pnpm test     # unit tests (pure text/layout helpers)
pnpm build    # host ESM + browser client bundle (lib/)

Layout

• src/index.ts — host half (placeholder).
• src/client/index.tsx — apply(): selection controller, overlay host, floating button, conversation.input.dock slot entry.
• src/client/selection.ts — selection capture + validation.
• src/client/format.ts — pure helpers (block building, draft append, label, button placement).
• src/client/bridge.ts — dock-slot → overlay bridge for the official composer faces.
