Before writing a CREATE ALERT 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.
4. Never use CREATE OR REPLACE — always use CREATE ALERT IF NOT EXISTS where supported.
5. Newly created alerts are suspended by default; remind the user to run ALTER ALERT <name> RESUME after creation.
6. The IF( EXISTS( <condition> )) block accepts SELECT, SHOW, or CALL statements; the action fires whenever one or more rows are returned.
7. For the THEN <action> block, use SYSTEM$SEND_EMAIL or SYSTEM$SEND_SNOWFLAKE_NOTIFICATION for notification-based alerts.
8. Omit SCHEDULE (or set to NULL) to create a streaming alert that triggers on new data; otherwise supply a cron expression or minute interval.
9. OR REPLACE and IF NOT EXISTS are mutually exclusive; never combine them.
