It is preferable over generic scrapers when you need BM25-focused excerpts aligned to a specific query, or when you want to minimize LLM context costs by getting a compression-ratio proof alongside the distilled output. The built-in 'structured' and 'skeleton' modes make it ideal for extracting tables or outlines from documentation pages.","instructions":null,"reviewSummary":null,"reviewSummaryHighlights":null,"reviewSummaryConcerns":null,"reviewSummaryGeneratedAt":null,"activationCount":0,"lastUsedAt":null,"lastSuccessfullyRanAt":null,"lastHealthCheckAt":"2026-10-23T06:35:37.051Z","isFirstParty":false,"canonicalSlug":"alpha-stream-agentdiet-dev-spa-markdown-reader-with-bm25-budget-control-d59313dd"}
