Select it. Quote it. Ask DeepSeek.

DeepSeek Harness is a text-first terminal/agent workspace. But quoting a piece of context back into the chat should be one gesture, not a copy-paste chore. dsh-selection-ask gives the web GUI a ChatGPT-style selection helper: select text in a conversation and a floating 「询问 DeepSeek」 button appears beside it. Click it — the selection is quoted into the composer as a Markdown blockquote (>), the composer is focused, and the caret is parked at the end. Just type your follow-up and send.

Why

• Zero friction quoting — the exact gesture you know from ChatGPT, in DeepSeek Harness.
• Official integration, no hacks — writes through the harness's inputActions.setDraft input-machine API, so undo history and draft persistence keep working. It never touches DSH internals or DOM state directly.
• One command to install — the compiled lib/ is committed, so a github: install fetches ready-to-load artifacts with no build step.

Features

• Button follows the selection — positioned at the selection's screen coordinates (position: fixed), clamped to the viewport, hidden once the selection scrolls away.
• Quotes conversation text only — selections must be inside the transcript ([data-conversation-scroll]); selecting inside the composer itself does nothing (quoting the draft back into itself is nonsense).
• Quote-aware append — every selected line gets a > prefix; an empty draft is replaced, a non-empty draft gets the quote appended as its own paragraph (blank line in between).
• Session-scoped — the button state resets on session switch, and the button hides while a takeover composer (question/approval) replaces the default one.

Requirements

• DeepSeek Harness with the web profile (dsh web), DSH packages of the 0.1.0-rc.6 era.
• A browser page on the harness GUI (http://127.0.0.1:3080 by default).
• Building from source needs Node ^22.19.0 || >=24 and pnpm. Installing the prebuilt package does not (compiled lib/ is committed).

Installation

1. Install the package

From GitHub (recommended)

dsh plugin --profile web add github:lzbaclz/dsh-selection-ask

Pin a release for reproducibility: dsh plugin --profile web add github:lzbaclz/dsh-selection-ask#v0.1.0

From a local clone

git clone https://github.com/lzbaclz/dsh-selection-ask.git
dsh plugin --profile web add link:/absolute/path/to/dsh-selection-ask

From npm (not published yet — dsh plugin --profile web add dsh-selection-ask will work once it is; see Roadmap)

2. Activate it

dsh plugin add already registers the package in your profile's dsh.profile.bundles list, and this package ships its own cordis.patch.yml, so the entry row is inserted automatically at boot. Choose one of the two activation paths — never both.

Path A — restart (zero YAML editing; recommended for new setups)

Restart dsh web (or just start it if it is not running). Done — no config files to edit.

# stop your dsh web process, then:
dsh web

Path B — hot activation on a running server (no restart)

Use raw pnpm (not dsh plugin, which would also register the bundle) so the bundles list is untouched, then patch the profile's patch layer, which DSH watches and applies live:

cd ~/.dsh/profiles/web
pnpm add github:lzbaclz/dsh-selection-ask

Now open ~/.dsh/profiles/web/cordis.patch.yml and replace the [] with the insert block — the file must stay a valid YAML list:

# BEFORE:
# Your patch layer for this dsh profile, applied after every bundle layer:
# a top-level YAML array of loader patch entries (id-targeted config
# overrides, disables, and insert lists; `!!js` expressions allowed).
[]

# AFTER:
# Your patch layer for this dsh profile, applied after every bundle layer:
# a top-level YAML array of loader patch entries (id-targeted config
# overrides, disables, and insert lists; `!!js` expressions allowed).
- insert:
    - id: dsh-selection-ask
      name: dsh-selection-ask
      config: {}

Save the file and refresh the browser page — the plugin is loaded.

⚠️ Do not combine Path A and Path B (e.g. dsh plugin add + a manual patch row): the entry would be registered twice and dsh web fails to boot with duplicate loader entry id: dsh-selection-ask.

⚠️ Do not append the YAML block after an existing [] — that produces an invalid file and dsh web fails to boot with failed to parse patches. Replace the [] as shown above.

If your profile is not named web, substitute your profile name; if you set a custom harness home, substitute your $DSH_HOME for ~/.dsh.

Older profiles (created by an earlier dsh version) may lack the autoInstallPeers: false line in pnpm-workspace.yaml. Add it so pnpm never tries to auto-install pre-release peers:

packages:
  - .

nodeLinker: hoisted
autoInstallPeers: false

3. Verify

Refresh the GUI page and select a sentence in the chat flow — the 「询问 DeepSeek」 button floats beside the selection. Click it: the text lands in the composer as a quote.

Usage

1. Select text anywhere in the conversation transcript.
2. Click the 「询问 DeepSeek」 button floating beside the selection.
3. The selection is quoted into the composer (> selected text), the composer is focused and the caret is at the end — type your follow-up question and send.

Uninstall

dsh plugin --profile web remove dsh-selection-ask

If you used Path B, also remove the insert block from cordis.patch.yml (put the [] back), then refresh / restart.

Troubleshooting

Development

The compiled lib/ is committed, so normal installs never need a build. To hack on it:

git clone https://github.com/lzbaclz/dsh-selection-ask.git
cd dsh-selection-ask
pnpm install
pnpm typecheck   # host + client tsc programs, zero errors
pnpm build       # tsc(host) + tsc(client) + tsdown bundle
pnpm verify      # offline smoke checks over the built artifacts

• src/index.ts — host half (empty apply; exists so the roster scan finds the package).
• src/client/index.tsx — browser half: injects CSS, registers into the conversation.input.overlay slot.
• src/client/SelectionAskButton.tsx — the floating button: selection detection, positioning, quote writing.
• src/client/quote.ts — pure buildQuote / appendQuote helpers (exercised offline by verify).
• src/client/styles.ts — button CSS + HMR-safe <style> injection.

After changing src/, rebuild, reinstall (or re-link:), and refresh the page.

How it works

The plugin registers a component into the session-scoped conversation.input.overlay slot, which grants it the session input kit (useInput, inputActions). A document-level selectionchange/mouseup listener detects selections inside the transcript and renders a position: fixed button at the selection's bounding rect. Clicking builds a Markdown quote, joins it with the current draft, writes the full draft through inputActions.setDraft — the input machine's official write path — then focuses the composer textarea.

Roadmap

• [ ] Publish to npm (dsh plugin --profile web add dsh-selection-ask).
• [ ] Optional keyboard shortcut (e.g. ⌘⇧Q) to quote the current selection.
• [ ] Configurable button label / language.
