Before writing a CREATE REPLICATION GROUP 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 REPLICATION GROUP IF NOT EXISTS.
5. Use the primary group syntax when creating in the source account; use the secondary (AS REPLICA OF) syntax when creating in a target account.
6. OBJECT_TYPES is required — always confirm which object types the user wants to replicate.
7. When DATABASES is in OBJECT_TYPES, ALLOWED_DATABASES is also required. Similarly, ALLOWED_SHARES is required when SHARES is included, ALLOWED_EXTERNAL_VOLUMES for EXTERNAL VOLUMES, and ALLOWED_INTEGRATION_TYPES for INTEGRATIONS.
8. ALLOWED_ACCOUNTS is required and must use org_name.account_name format.
9. Unlike failover groups, replication groups do not support automatic failover — clarify this distinction if the user's intent is high availability.
