List all comments on a Fizzy card, sorted chronologically (oldest first).
AI agents call fizzy_list_comments to retrieve information from Fizzy Do MCP 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 existing comments from a card in chronological order. It performs no data creation, modification, deletion, or execution of operations. The operation is read-only with minimal security impact even if misused by an AI agent, as it only exposes information the user already has access to in the project management system.
From the tool's definition Tool name 'fizzy_list_comments' and description 'List all comments on a Fizzy card' indicate a data retrieval operation with no modifications or side effects.
