Get users who liked a specific comment.
AI agents call get_comment_likers to retrieve information from Instagram without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about who liked a comment—a read-only query operation. It has no side effects, does not execute code, does not create, modify, or delete data, and does not involve financial transactions. The blast radius of misuse is minimal since it only exposes already-public engagement metrics that Instagram users can view directly.
From the tool's definition Tool name 'get_comment_likers' and description 'Get users who liked a specific comment' indicate a retrieval operation that queries publicly visible engagement data without modifying or deleting anything.
