# 🔍 Cross Search — DSH-Plugin

> **多引擎交叉驗證搜索**:Brave / Tavily / DuckDuckGo / Wikipedia(可選 Bing / Mojeek)並行查詢,URL 去重,**按獨立引擎同意數分置信度**——單引擎結果誠實標為 LOW。

## Confidence tiers

| Tier | Condition | Meaning |
| --- | --- | --- |
| 🟢 HIGH | ≥ 50% of running engines agree | independently verified |
| 🟡 MEDIUM | ≥ 2 engines agree | partially verified |
| 🔴 LOW | single engine | honest unverified |

## Tool

`cross_search { query, engines?, limit? }` — parallel fetch, URL dedupe
(tracking params stripped), tiered ranking, engine provenance per result.

## API keys (env)

| Engine | Env var | Keyless fallback |
| --- | --- | --- |
| Brave | `BRAVE_API_KEY` | — |
| Tavily | `TAVILY_API_KEY` | — |
| Bing | `BING_API_KEY` | — |
| Mojeek | `MOJEEK_API_KEY` | — |
| DuckDuckGo | — | ✅ (HTML endpoint) |
| Wikipedia | — | ✅ (REST API, `wikiLang` config) |

Missing keys skip that engine; the report always states which engines ran.
