dsh-screenshot-chat
DSH composer 的屏幕截图功能：在聊天输入框的 + 菜单中添加 Screenshot 选项，支持区域截图和隐藏窗口变体。该变体会在原生 macOS 选择叠加层出现前隐藏当前窗口，并在之后恢复；截图会作为图像附件添加到输入框中。
插件会安装到这里；不确定时保持 web。

A DeepSeek Harness plugin that adds a Screenshot entry to the chat composer's + menu, so a region captured on your Mac lands in the input box as an image attachment.

Pressing Esc or right-clicking cancels silently.○ Hide window). Turn it on and the window that is frontmost when you click is hidden first, then the selection overlay appears; when the capture finishes or is cancelled, the window is restored and brought back to the front.localStorage and survives page reloads. While it is on, the menu item's description also shows the active mode, so you can see it without hovering.screencapture (anything other than macOS).dsh plugin add dsh-screenshot-chat
Then restart DeepSeek Harness (or reload the web client) so the bundle is composed.
Point a profile at a checkout instead of the published package:
{
"dependencies": {
"dsh-screenshot-chat": "link:/absolute/path/to/dsh-screenshot"
},
"dsh": { "profile": { "bundles": ["...", "dsh-screenshot-chat"] } }
}
Run pnpm install in the profile. With HMR enabled, config changes apply immediately; otherwise restart DSH. Host-side edits (index.js) take effect after touching the profile's cordis.patch.yml (any change re-composes the tree without a restart); client-side edits (client.js) are hot-replaced by the client HMR poll.
+ → Screenshot in the composer.To capture without the DSH window in the shot, hover the menu entry, switch on Hide window, then click Screenshot. The window disappears during selection and comes back afterwards.
Override the defaults from your profile patch, keyed by the plugin id:

config:
timeoutMs: 180000 # how long the region selection may stay open
index.js)Registers same-origin routes under /.dsh-screenshot on the host web server:
POST /capture with body { "hide": true | false }
screencapture -i -x -o <tempfile>, waits for the selection, then returns the PNG as base64 and deletes the temp file immediately. A cancelled selection returns { cancelled: true }.hide: true it first resolves the frontmost process name through AppleScript (System Events) and hides it (the equivalent of ⌘H, with a system-level denylist — Finder, Dock, System Settings and friends are never hidden), waits for the hide animation to settle (350 ms), then captures. A finally block restores and re-focuses the window whether the capture succeeded, was cancelled, or timed out.GET /health lets the browser half probe platform support (the entry is hidden off macOS).Only one capture may run at a time. A capture that stays open longer than timeoutMs (default 180 s) is terminated, and osascript calls time out after 60 s.
client.js)Contributes a screenshot command to the + menu through commandUi.register (kind: 'action', so a click runs the current mode). A document-level mouseover delegate spots the menu row carrying the data-dsc-icon marker and mounts the hover toggle inside it, using native listeners and inline styles so it does not depend on the menu component's internal class names. mousedown and click on the toggle stop propagation so the row is not selected.
The returned image is wrapped in a File and handed to conversation.createDrafts plus the composer's addFiles — the exact same attachment path as pasting an image, so previews, size limits, and upload encoding all run through the host's existing logic.
screencapture -i, so the plugin works on macOS only; the menu entry hides itself elsewhere.MIT
