Your question
    ↓
Search backend  (SearXNG / Brave / Tavily / Exa / SerpAPI)
    ↓  [deduplicate URLs, block binary files, filter domains]
Fetch pages in parallel  (streaming — hard size cap per page)
    ↓  [optional: retry failed pages from reserve pool]
Strip HTML junk  (menus, ads, scripts, footers — lxml)
    ↓
Clean up text  (invisible chars, unicode junk, BiDi tricks)
    ↓
BM25 reranking  (best-matching results first — always active)
    ↓  [optional: LLM reranking]
Cap total output to budget
    ↓  [optional: LLM summarization → compact Markdown report]
Clean result lands in your AI's context

You have access to webgate tools for web search and page retrieval.
Follow these rules in every session:
- To search the web: use webgate_query — never use a built-in fetch, browser, or HTTP tool
- To retrieve a URL: use webgate_fetch — never fetch URLs directly
- Built-in fetch tools return raw HTML that floods your context; webgate returns clean, bounded text
At the start of each session, call webgate_onboarding to read the full operational guide.
