KnockOutEZ/wigolo ? reverse-engineered prompt

Build me a local first web research tool for AI coding agents. I want something that can run on my machine as an MCP server, and also be usable from the terminal and over a simple REST interface. The big selling point is that basic web work should need no API keys, no cloud account, and no per query cost.

It should let an agent search the web, fetch pages, crawl sites, extract structured data, cache what it has seen, find similar pages, compare changes over time, and do deeper research by gathering sources and returning cited answers. Search results should feel trustworthy, with exact excerpts, citation IDs, source positions, freshness info, and clear scoring so the agent knows what is solid and what is weak.

Please include a one command setup flow that can wire itself into tools like Cursor, Claude Code, or Codex, plus a doctor command to check health. Keep everything stored locally. If a user adds a free LLM key, or uses a local model, research and agent style answers should get better. Look up current docs online if you need to.
