AI agents call vs_ecc_health to retrieve information from VibeServe without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves diagnostic/status information about ECC integration without modifying, executing, or deleting anything. It is a non-invasive inspection tool. Severity is low because exposing integration status poses minimal risk even if an agent calls it unexpectedly.
From the tool's definition Tool description states 'Check ECC integration status — skills loaded, rules available.' The verb 'check' and the action of querying status information indicate a read-only operation with no side effects.
