WHAT IT DOES

What witness_export does on Hamza Agent Hub 252

AI agents call witness_export to retrieve information from Hamza Agent Hub 252 without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why witness_export is rated Low

'Export' of an audit chain is primarily a read/retrieval operation — it extracts and outputs existing data for review. No mutation, deletion, or execution is implied. Severity is medium because the exported chain may contain sensitive agent state, memory, or workflow data that could be leveraged if exfiltrated.
