dsh-plugin-youcom

The DeepSeek Harness web seam (ctx.web) needs third-party plugins to actually reach the internet. dsh-plugin-youcom fills both slots at once: it registers a You.com-powered WebSearchProvider and a WebFetchProvider, so an AI assistant can run web searches and pull cleaned page content mid-conversation without you wiring up a separate fetch service.

On the search side, POST /v1/search returns web results and, by default, merged news items, with numResults letting you set a default page size. On the fetch side, POST /v1/contents is handled server-side by You.com, which extracts the readable text and returns it as content. Both endpoints share a single configurable baseURL, making it straightforward to route through a reverse proxy or an internal gateway. The only mandatory setting is a You.com API key; everything else has sensible defaults, so the setup is a few lines of YAML.

This plugin is aimed at developers building on DeepSeek Harness who want to give their model a quick "look it up" and "read this page" capability without rolling their own provider. It is framework-agnostic and plugs straight into the dsh web seam. A few protocol-level caveats worth knowing: the fetch endpoint always reports statusCode 200 and truncated false (You.com's API does not surface the origin status or a truncation flag), and search responses are source lists only with no AI-generated answer attached. The plugin passes these through faithfully rather than masking them.
