qikairo7/dsh-web-search-fetch

Aggregated web_search and web_fetch providers for DeepSeek Harness, sitting behind the built-in tools. Search fans one query out to AnySearch, Zhipu and Zhihu concurrently, dedupes URLs, fuses ranks with Reciprocal Rank Fusion and optionally reranks through SiliconFlow. Fetch is URL-aware: static pages pass through the built-in HTTP fetcher, dynamic ones fan out to Firecrawl and AnySearch extract and pick one body by quality. One shared circuit breaker skips an engine for the day after a quota or 429 signal, and a settings card keeps each engine API key in the credential store without ever showing its value.
