go-goose

Expert guidance for using pressly/goose to create and run database migrations via the CLI or Go library.

When to trigger

• The user mentions goose, pressly/goose, database migrations in Go, or asks how to run SQL/Go migrations.
• The task involves embedding migrations, provider API usage, or CI workflows with goose.

Core rules

• Follow the repository's existing migration layout, dialect, and naming conventions first.
• Ensure the database driver and goose dialect match (e.g., postgres driver with postgres dialect).
• Prefer SQL migrations for schema changes; use Go migrations for complex data backfills or code-driven steps.
• Keep migrations deterministic and idempotent within goose's rules (one Up, optional Down).

Workflow

1. Clarify context: target DB/dialect, driver, migration directory, SQL vs Go migration needs, and desired command (create/up/down/status/etc).
2. Choose interface:
   • CLI for ad-hoc runs or CI/CD.
   • Library/Provider when migrations are executed inside Go services or tests.
3. Author migrations:
   • SQL: use goose annotations and statement rules (see references/sql-annotations.md).
   • Go: register migrations in init and wire into a custom binary or Provider (see references/go-migrations.md).
4. Run migrations:
   • CLI usage, commands, and env vars in references/cli.md.
   • Library/Provider patterns in references/library.md.
5. Versioning + ordering:
   • Use hybrid versioning during development and fix for production sequencing if required (see references/versioning.md).

Output expectations

• Provide exact commands or code snippets that match the user's dialect and environment.
• Warn about missing Down migrations when rollbacks are required.
• If a migration requires special parsing or non-transactional execution, call it out explicitly.
