Fetch the WASP structural index for a webpage. Returns a manifest with the page title, summary, keywords, language, and a list of heading sections (chunks) with their anchors and token estimates. Checks /.well-known/wasp.json first (native manifest); falls back to DOM-generated manifest if not found.

Fetch the plain-text content of a specific section of a webpage by its CSS anchor. Call get_manifest first to discover available anchors. Uses a three-stage anchor resolution: getElementById → querySelector → fuzzy heading match.

Ask a natural-language question about a webpage. Internally runs the full WASP two-tier retrieval pipeline: fetch manifest → score relevant chunks → fetch chunk content → call Claude API → return answer with inline citations. Requires ANTHROPIC_API_KEY environment variable (or OPENAI_API_KEY for provider=openai).
