What hippo_diagnose_failure does on Verimem
AI agents call hippo_diagnose_failure to retrieve information from Verimem without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why hippo_diagnose_failure is rated Low
The tool appears designed to analyze and retrieve diagnostic information about failures, consistent with Read category (query/analyze operations). The incomplete description ('diagnose root cause of a' cuts off mid-sentence) lowers confidence, but the diagnostic/analytical intent and absence of any write, execute, or destructive keywords supports Read classification.
From the tool's definition Tool name 'hippo_diagnose_failure' and partial description 'diagnose root cause of a' suggests analysis and querying of diagnostic data without modification. No language indicating deletion, execution, or state changes.
