A tool to create a frequency table from a collection
AI agents call frequency_table_creator to retrieve information from JeffersonStats without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only statistical computation, transforming input data into a frequency table. It does not write, execute, delete, or involve financial operations. It is purely analytical, consistent with sibling tools like descriptive_statistics_summary and correlation_calculator.
From the tool's definition 'create a frequency table from a collection' — reads/analyzes input data to produce a statistical summary with no side effects
