Ideal for agent orchestrators building swarms that need to dynamically find the right tool at runtime. The built-in Prompt-Guard firewall makes it preferable over raw tool registries when security against prompt injection is a concern. The 85% token compression is especially valuable when running many discovery queries in a token-constrained context.","instructions":null,"reviewSummary":null,"reviewSummaryHighlights":null,"reviewSummaryConcerns":null,"reviewSummaryGeneratedAt":null,"activationCount":0,"lastUsedAt":null,"lastSuccessfullyRanAt":null,"lastHealthCheckAt":"2026-10-23T06:31:27.705Z","isFirstParty":false,"canonicalSlug":"serp-extract-agentdiet-dev-universal-a2a-mcp-tool-discovery-safe-8d70db86"}
