Before writing a CREATE FILE FORMAT statement:

1. Read references/parameters.md to review all available parameters and their defaults.
2. For each parameter, decide whether the user's request implies a non-default value.
3. Include only the parameters that differ from the default or that the user explicitly requested — do not bloat the DDL with unnecessary clauses.
4. Never use CREATE OR REPLACE — always use CREATE FILE FORMAT IF NOT EXISTS.
5. Always specify the TYPE parameter explicitly, even though CSV is the default, to make the format self-documenting.
6. For CSV formats, pay special attention to FIELD_OPTIONALLY_ENCLOSED_BY, NULL_IF, SKIP_HEADER, and COMPRESSION — these are the most commonly customized options.
7. AVRO, ORC, and XML formats are for loading only; do not use them for unloading.
8. Do not combine OR REPLACE and IF NOT EXISTS in the same statement — they are mutually exclusive.
