## Why kb_search is rated Low

Based on the tool name 'kb_search', this appears to be a read-only operation that queries a knowledge base and returns results without side effects. While the empty description reduces confidence slightly, the semantic meaning of 'search' in this context implies data retrieval. Confidence is not higher due to the lack of explicit documentation confirming no write or execute capabilities.

## Use case

AI agents call kb_search to retrieve information from Container-MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)
