Get comprehensive information about a specific link.
AI agents call describe_link to retrieve information from Yamcs 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 queries information about a link in the Yamcs mission control system. There are no side effects, no data modification, no command execution, and no destructive or financial operations. The action is purely informational, making it a Read category tool with low severity since misuse would only result in information disclosure about link configuration or status.
From the tool's definition Tool name 'describe_link' and description 'Get comprehensive information about a specific link' indicate data retrieval without modification.
