List available Gas Town formulas with optional type filter
AI agents call gt_formula_list to retrieve information from Claude Flow without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

No execution, deletion, or financial operations are involved. Classification as Read with low severity is appropriate for a simple enumeration utility.
