Fetch all comments on a ProofHub task, including their full text.
AI agents call proofhub_get_comments to retrieve information from ProofHub 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 existing comment data from ProofHub tasks without creating, modifying, or deleting any information. It is a pure read operation that queries and returns data. No irreversible changes, code execution, or financial implications are possible. The low severity reflects that exposing task comments presents minimal risk compared to other tool categories.
From the tool's definition Tool name contains 'get_comments' and description states 'Fetch all comments on a ProofHub task' — a retrieval operation with no modification or side effects.
