AI agents call jira_get_comments to retrieve information from Atlassian 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 comments associated with a Jira issue. It performs a read-only operation that does not modify, delete, execute, or create any data. The blast radius of misuse is minimal — an AI agent could only retrieve comments that already exist, potentially exposing sensitive information in comments but not causing irreversible damage or executing external code.
From the tool's definition Tool name is 'jira_get_comments' and description states 'Gets all comments for a Jira issue' — a retrieval operation with no side effects.
