dsh-appshots: Capturing the Foreground Window and Injecting Context

dsh-appshots is an automation plugin designed for DeepSeek Harness Desktop, addressing the challenge of large language models understanding application interfaces. It supports macOS and Windows, accurately captures the frontmost window, adds the screenshot as a draft attachment, and extracts window text to inject into the model context. After installation, users can trigger screenshots with a keyboard shortcut; DSH automatically brings the window to the front, requiring no manual operation. It provides rich configuration options, including skipping its own window and controlling text injection. When using it, users should grant the system Screen Recording and Accessibility permissions. Text extraction depends on the system accessibility tree, so some terminals or protected content may not be readable.
