list_api_versions
AI agents call list_api_versions to retrieve information from Awslabs Valkey without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name strongly suggests listing/retrieving API version information, which is a read-only query operation. The empty description reduces confidence slightly, but the semantic meaning of 'list' is consistently associated with non-destructive data retrieval. This poses minimal risk if misused by an AI agent.
