What snow_auth_diagnostics does on Serac
AI agents call snow_auth_diagnostics to retrieve information from Serac without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why snow_auth_diagnostics is rated Low
The tool reads and tests authentication state, token validity, and permission configurations. It does not modify, execute, or delete anything — it diagnoses and reports. However, it exposes sensitive security configuration details (OAuth tokens, API access, table permissions), which raises the severity to medium since misuse could leak credential or permission information useful for privilege escalation.
From the tool's definition Performs comprehensive authentication and permission diagnostics. Tests OAuth tokens, API access, table permissions, and provides specific remediation steps.
