It is uniquely useful when you need BM25-focused extraction around a specific query topic with a hard token ceiling, or when you want quantified ROI proof of compression savings. Prefer it over generic scrapers when you care about LLM cost efficiency and need clean, agent-ready output rather than raw HTML.","instructions":null,"reviewSummary":null,"reviewSummaryHighlights":null,"reviewSummaryConcerns":null,"reviewSummaryGeneratedAt":null,"activationCount":0,"lastUsedAt":null,"lastSuccessfullyRanAt":null,"lastHealthCheckAt":"2026-10-21T07:26:20.499Z","isFirstParty":false,"canonicalSlug":"mcp-security-agentdiet-dev-web-url-prompt-compressor-with-bm25-budget-0e244da9"}
