AI agents call pr_get to retrieve information from Pr Review without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves existing pull request comment data without creating, modifying, deleting, or executing operations. The blast radius of misuse is minimal—an agent could over-retrieve comments but cannot cause data loss or trigger external actions. Therefore, it is categorized as Read with low severity.
From the tool's definition Tool retrieves 'detailed comment information including full body and AI prompt' with no indication of modification or side effects. The verb 'Get' and action of retrieving data classifies this as a Read operation.
