description	Create new SQL migration files for multiple database dialects (sqlite3, mysql, postgres, tidb, redshift, clickhouse)
disable-model-invocation	true
allowed-tools	Bash
argument-hint	["migration_name"]

Create new migration files named $ARGUMENTS for all configured database dialects.

Run the wrapper script:

bash scripts/create-migration.sh $ARGUMENTS

If the script is not found, fall back to finding all rockhopper_*.yaml config files and running rockhopper --config <config> create --type sql $ARGUMENTS for each.

After creation, list the newly created files and remind the user to edit all migration files since each dialect may need different SQL syntax. OLAP dialects diverge the most — e.g. ClickHouse tables need a MergeTree() / ORDER BY engine clause instead of a primary key, use Int64/String/DateTime types, and have no AUTO_INCREMENT.

Migration file format reference

-- @package packagename
-- +up
CREATE TABLE example (id INT PRIMARY KEY);

-- +down
DROP TABLE example;

For multi-statement blocks, use -- +begin / -- +end. Use -- !txn to disable transaction wrapping.
