List all supported oilfield unit categories and their units.
AI agents call list_oilfield_units to retrieve information from Petropt/petro without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays available unit categories and conversions—a straightforward read operation. It queries static reference data without modifying, executing external operations, or affecting any system state. The narrow scope and informational nature result in low severity and blast radius if misused.
From the tool's definition Tool name 'list_oilfield_units' and description 'List all supported oilfield unit categories and their units' indicate a data retrieval operation with no side effects.
