yarAnalyzer creates statistics on a Yara rule set and files them in a sample directory. It will generate two tables as command line output and two CSV files. (yaranalyzer_file_stats.csv, yaranalyzer_rule_stats.csv). This will create a CSV file named yara-rule-inventory.csv (default, set with '-o') with information about the initialized rules. (Rule File;Rule Name;Description;Reference).
