list-custom-line-item-versions
AI agents call list-custom-line-item-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 'list' verb indicates a data retrieval operation with no side effects. Although the description is empty (reducing confidence), the clear naming pattern suggests this tool queries or enumerates existing custom line item versions rather than creating, modifying, or deleting them. This is consistent with standard AWS API naming conventions where 'list' operations are read-only.
