Get the count of unread messages in the inbox.
AI agents call keyid_get_unread_count to retrieve information from KeyID Agent Kit without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool merely retrieves and returns a count of unread messages—a simple data query with no side effects, no code execution, no data modification, and no destructive capability. It falls squarely into the Read category. Severity is low because misuse by an AI agent would only expose message statistics, not sensitive message content or enable harmful actions.
From the tool's definition Tool name 'keyid_get_unread_count' and description 'Get the count of unread messages in the inbox' indicate a read-only query operation that retrieves message count metadata without modifying, executing, or deleting any data.
