List all comments on a Fizzy card, sorted chronologically (oldest first).
AI agents call fizzy_list_comments to retrieve information from Fizzy 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 displays existing comments on a card in chronological order. It performs no creation, modification, deletion, or execution of external operations. The read-only nature and lack of side effects place it squarely in the Read category with low severity, as comment data is typically non-sensitive task management information and misuse would only expose data rather than cause harm.
From the tool's definition Tool name 'fizzy_list_comments' and description 'List all comments' indicate data retrieval with no side effects. The phrase 'sorted chronologically' confirms a query/fetch operation with no modification capability.
