获取所有证据的单篇 AI 总结（收集完整的流式响应后返回）
AI agents call all_evidence_summary to retrieve information from KnowS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and analyzes medical evidence data to generate summaries. It has no side effects—it performs read-only operations on evidence data. The streaming response mechanism is a delivery detail, not an action that creates, modifies, or deletes data. This fits the 'Read' category (retrieves or queries data; no side effects).
From the tool's definition Tool name 'all_evidence_summary' and description indicate retrieval and summarization of existing evidence ('获取所有证据的单篇 AI 总结' = 'get AI summary of all evidence').
