Unverified工具可分为「补偿智能不足的工具」和「随智能增长的工具」，前者会强迫特定写代码顺序且无法随模型变强受益，后者随模型越强越有用73% similarUnverifiedThe per-agent code wrapper approach breaks down when managing dozens of agents each with their own tools, MCP servers, and credentials; policy needs to be centralized into a single layer through which all calls pass.73% similarUnverifiedThe way to fix MCP tool bloat is to filter by tool name and keep only the tools the task needs; in the demo this reduced 16 tools to 2 essential tools.72% similarUnverifiedIn agent development, rather than repeatedly polishing prompts, it is better to spend effort on designing tool interfaces.72% similarUnverifiedIf an agent frequently selects the wrong tool or passes the wrong parameters, one should prioritize optimizing the prompt, tool descriptions, and model selection, rather than switching the tool protocol (such as switching from function calling to MCP).71% similar
