dsh-web-search-tavily

DeepSeek Harness exposes a web search seam (ctx.web) that ships with an official channel by default. dsh-web-search-tavily lets you swap that engine to Tavily with minimal friction. It registers as a search Provider under ctx.web without modifying the seam itself or introducing a model-facing tool, so the model experience stays governed by dsh-tool-web as before. A practical standout is the keyless path: when no API key is found in any source, the plugin automatically switches to Tavily's keyless mode, sending no Authorization header and only being subject to server-side rate limits, which is enough for trials, CI demos, or evaluating search quality before keying in.

Configuration spans every official Tavily search parameter: depth, topic, time range, start/end dates, result count, domain include/exclude lists, structured answer, raw content, images, favicon, usage stats, exact match, language, country, and chunks-per-source. All fields are editable from a visual settings card or programmatically. Credentials can come from a literal value, the dsh-credentials service, or an environment variable, with a clear resolution order and guaranteed redaction from config documents. The card ships with one-click recommended defaults, auto-detected key status, and per-field token-cost hints to keep experimentation cheap.

Best suited for developers who want to replace or supplement the default search in Harness with Tavily, teams that need fine-grained control over depth, domain filtering, or structured answers, and individuals who have not yet requested an API key and want to validate search quality in keyless mode first.
