The evaluation of tools like AgentCore, Exa, GNU parallel, and Perplexity involves complex multi-layered systems, and each layer can technically succeed while failing the user's underlying goal. The analysis emphasizes the need for more granular proofs beyond transport success to accurately assess search quality and tool functionality. AI
