网络搜索策略。当需要搜索网络信息、查询最新资料、查找技术文档、或选择搜索工具时,必须使用此技能。定义了多层搜索工具优先级链,同层并发、失败即降级。

网络搜索

核心原则

  1. 先读注册表~/.claude/tool-registry.json 记录了每个工具的实测状态。
  2. 同层并发。独立通道同时发起,谁先返回用谁。
  3. 失败即降级,不重试。一个工具失败一次就跳到下一层。

优先级链

Tier 0 — 直接 URL

用户给了 URL 或你知道目标地址 → 不搜索,直接提取页面内容。优先用内置 WebFetch(<1s,覆盖 90% 页面);JS 渲染/反爬页面用 Crawl4AI(需 Python 环境);Crawl4AI 超时或被检测时降级到原生 Playwright 拿 inner_text

Tier 1 — WebSearch(内置,零配置)

WebSearch 是 Claude Code 内置工具,零依赖、零成本、结构化返回。始终最先尝试。失败(如当前模型不支持)则立即降级到 Tier 2。

Tier 2 — Tavily / SearXNG(并列)

Tavily — ~0.6s 响应,JSON 结构化返回,不限频,英中文均可。1000 次/月。

references/tavily.md

SearXNG — 自部署 Docker,零额度限制,~3s 响应,中文 18 条/Tavily 5 条。

references/searxng.md

Tier 3 — web_search_prime MCP

域名过滤、时效性、内容长度控制优于 Tavily。有月额度,备选。

references/web-search-prime.md

Tier 4 — DuckDuckGo(兜底)

纯免费但 ~2s、HTML 需解析、限频。仅在前三层全部不可用时使用,降级前告知用户。

references/duckduckgo.md

降级流程

需要搜索
  ├─ WebSearch (内置)           ──失败──┐
  │                                   ▼
  ├─ Tavily curl (Bash)      ──失败──┐
  ├─ SearXNG (本地 Docker)    ──失败──┤
  │                                   ▼
  ├─ web_search_prime MCP     ──失败──┐
  │                                   ▼
  └─ DuckDuckGo curl           ── 兜底

搜索拿到 URL 后,提取页面内容:优先 WebFetch(内置,<1s)→ JS 重/反爬页用 Crawl4AI(magic=True 解微信)→ 超时或被检测时降级到原生 Playwright(wait_until=commit)。

结果展示

每条搜索结果必须附带链接,让用户能直接点开看原文。格式:

1. **标题** — 来源

维护

工具状态变更时更新 ~/.claude/tool-registry.json

环境依赖

依赖用途安装方式磁盘必需
Tavily API Key首选搜索,~0.6s,1000次/月注册 tavily.comexport TAVILY_API_KEY=xxx0
ddgs兜底搜索,防 CAPTCHApip install ddgs~1MB

Keep looking

Skills are one crate of 328,083. Ordering is by how many stacks a row turns up in, so the top of any crate is what has actually been picked rather than what has the most stars.
