dsh-ventus-search

Running web searches inside DeepSeek Harness with a single engine often means dealing with timeouts, anti-bot redirects, ad clutter, and the absence of any unified ranking or fault tolerance. dsh-ventus-search registers Bing, 360, and Bilibili as a group of concurrent providers under ctx.web. Results are scored by title hit, snippet hit, and rank weight, then normalized, deduplicated, redirect-decoded, and capped per domain so a single query returns clean, clickable sources.

The resilience chain is thorough: a failing engine is isolated automatically, a backup query retries, an overall timeout returns whatever partial results exist, and if every engine fails the plugin returns an empty array instead of throwing. A query-level LRU cache (capacity 100, TTL 300 s) combined with AbortSignal propagation keeps repeat requests nearly free. The fetch side includes an ad and tracker domain blacklist with subdomain matching, a Readability-style content extractor, mirror-domain fallback, and a size cap, so consumers get readable article text rather than raw HTML.

It is aimed at developers who need frequent Chinese and English web lookups inside DSH conversations without hand-wiring each search engine API, as well as teams building agents that require dependable web_search and web_fetch primitives with observable per-engine health, a visual settings card, and graceful degradation out of the box.
