dsh-video-downloader

Within the DeepSeek Harness ecosystem, browser-automation plugins exist, but a dedicated media downloader tool was missing, making it inconvenient to directly grab videos or audio from Bilibili, YouTube, Douyin, or Xiaohongshu right from an agent conversation. The dsh-video-downloader plugin steps in to fill this gap by extracting the media-detection logic originally embedded in a browser extension and transforming it into pure Node.js functions, exposed as three streamlined tools for the model. Its core capabilities unfold across three layers: first, the video_analyze tool enables pure offline analysis of a URL to determine if it's media, identify the source platform, and retrieve metadata like quality and format; second, the video_download tool lets you stream media to disk with browser-like request headers, supporting redirects and a timeout; and third, video_quality_parse offers a quick regex-based extraction of quality and extension. Built as a zero-build-step pure ESM package, the published module is the runtime code itself, and its core pure functions (e.g., isMedia, detectSite) are exported for testing or extension. It is ideally suited for DeepSeek Harness developers, content creators, or researchers—anyone needing to integrate media detection and downloading into automated agent workflows. Whether you're building an automated content collection pipeline or simply want to quickly save online videos within a conversation, dsh-video-downloader provides a lightweight, reliable, and extensible solution.
