I need to compute distribution statistics for all numeric columns in the dataset. From the evidence so far, I can see that step-5 gave me the columns of `beer_ratings`, but I need to systematically query all numeric columns across all tables in the dataset.

Let me write a comprehensive SQL query to get min, max, mean, median, and standard deviation (spread) for all numeric columns across all tables.

```json
{
  "action": "tool_call",
  "reasoning": "I need to compute distribution statistics (min, max, mean, median, stddev) for all numeric columns across all tables. I'll query the metadata to identify numeric columns, then compute their statistics in a single query per table. Starting with the largest table (beer_ratings) which I know has several numeric columns from step-5.",
  "tool": "query_sql",
  "args": {
    "sql": "SELECT 'beer_ratings' as table_name, 'aroma' as column_name, MIN(aroma) as min_val, MAX(aroma) as max_val, AVG(aroma) as mean_val, MEDIAN(aroma) as median_val, STDDEV(aroma) as stddev_val FROM raw.beer_ratings UNION ALL SELECT 'beer_ratings', 'flavor', MIN(flavor), MAX(flavor), AVG(flavor), MEDIAN(flavor), STDDEV(flavor) FROM raw.beer_ratings UNION ALL SELECT 'beer_ratings', 'mouthfeel', MIN(mouthfeel), MAX(mouthfeel), AVG(mouthfeel), MEDIAN(mouthfeel), STDDEV(mouthfeel) FROM raw.beer_ratings UNION ALL SELECT 'beer_ratings', 'appearance', MIN(appearance), MAX(appearance), AVG(appearance), MEDIAN(appearance), STDDEV(appearance) FROM raw.beer_ratings UNION ALL SELECT 'beer_ratings', 'overall', MIN(overall), MAX(overall), AVG(overall), MEDIAN(overall), STDDEV(overall) FROM raw.beer_ratings UNION ALL SELECT 'beer_ratings', 'total_score', MIN(total_score), MAX(total_score), AVG(total_score), MEDIAN(total_score), STDDEV(total_score) FROM raw.beer_ratings UNION ALL SELECT 'beer_ratings', 'description_score', MIN(description_score), MAX(description_score), AVG(description_score), MEDIAN(description_score), STDDEV(description_score) FROM raw.beer_ratings",
    "purpose": "Get distribution statistics for all numeric measure columns in beer_ratings table",
    "source": "raw"
  }
}
