Get detailed profile information for a specific user
AI agents call slack_get_user_profile to retrieve information from Server Puppeteer without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves user profile data from Slack without modifying, deleting, or executing any operations. It is a straightforward query operation that matches the 'Read' category. Severity is low because user profile information is typically non-sensitive metadata, and the blast radius of misuse is limited to information disclosure of publicly-available or semi-public profile data.
