Generate a plain-English data dictionary from a table schema

I want to create a data dictionary for a database table so that analysts unfamiliar with it can use it independently. Here is the context:

- Table name: {{TABLE_NAME}}
- Schema / column list (paste DDL, column names + types, or a header row): {{SCHEMA_INPUT}}
- Business domain this table lives in: {{BUSINESS_DOMAIN}}
- Any column names or codes whose meaning I already know: {{KNOWN_DEFINITIONS}}

Please do the following:

1. Produce a table with these columns: Column Name | Data Type | Plain-English Description | Example Values | Common Pitfalls.
2. For any column whose name is ambiguous or abbreviated, write two plausible interpretations and mark them clearly so I can confirm the correct one.
3. Identify columns that are likely foreign keys or join candidates based on naming conventions (e.g., suffixes like _id, _key) and note what table they probably link to.
4. Flag any columns where nullability or data type suggests a data-quality risk (e.g., a revenue column stored as VARCHAR).
5. Write a 2-sentence table-level summary I can paste at the top of the dictionary that describes what this table represents and its typical grain (one row per what?).

Note: if the schema is very large (50+ columns), focus the pitfalls column on the 10 highest-risk columns and note which ones you skipped.
