Web search returning results as clean numbered markdown. Two selectable backends: a local SearXNG instance (SEARXNG_URL, the default path for everyone) and TinyFish's hosted API (opt-in: SEARCH_BACKEND=tinyfish plus a TINYFISH_API_KEY or ask-auth credentials key). The capability layer (WebSearch.search); the native Ask::Tools::WebSearch agent tool is an optional integration that registers when ask-tools is present.
