516 Frameworks Micronaut Mongodb Migrations Mongock Agent Skill

Use when you need to add or review Mongock MongoDB data migrations in a Micronaut application — including Mongock runner/driver selection, Micronaut bean wiring, migration scan packages, @ChangeUnit classes, lock/transaction settings, and Testcontainers verification. This should trigger for requests such as Add Mongock migrations in Micronaut; Review Micronaut MongoDB data migrations; Configure Mongock change units with Micronaut Data MongoDB; Create Mongock change units for Micronaut MongoDB; Review Mongock migration ordering in a Micronaut service.

Micronaut - MongoDB migrations (Mongock)

Apply Mongock migration guidelines for Micronaut and Micronaut Data MongoDB.

What is covered in this Skill?

Mongock runner/driver selection for Micronaut projects
Micronaut bean wiring for MongoDB client access and controlled migration execution
Code-first @ChangeUnit migrations with @Execution and rollback hooks
Locking, idempotency, transaction limits, and startup/runtime trade-offs
Integration tests with @MicronautTest and Testcontainers MongoDB
Coordination with @515-frameworks-micronaut-mongodb

Scope: Apply recommendations based on the reference rules and good/bad examples.

Constraints

Compile before Mongock or MongoDB migration changes; verify after changes.

MANDATORY: Run ./mvnw compile or mvn compile before applying any change
SAFETY: If compilation fails, stop immediately
VERIFY: Run ./mvnw clean verify or mvn clean verify after applying improvements
BEFORE APPLYING: Read the reference for detailed rules and good/bad patterns
EDGE CASE: If a Micronaut-specific Mongock runner is unavailable or incompatible, use an explicit standalone runner bean/job and document that trade-off

When to use this skill

Add Mongock migrations in Micronaut
Review Micronaut MongoDB data migrations
Configure Mongock change units with Micronaut Data MongoDB
Create Mongock change units for Micronaut MongoDB
Review Mongock migration ordering in a Micronaut service

Workflow

Read references and inspect MongoDB setup

Read references/516-frameworks-micronaut-mongodb-migrations-mongock.md, references/516-frameworks-micronaut-mongodb-migrations-mongock-antipatterns.md, and references/516-frameworks-micronaut-mongodb-migrations-mongock-parallel-change.md, then inspect pom.xml, Micronaut MongoDB configuration, and existing @515-frameworks-micronaut-mongodb persistence patterns.

Choose runner, driver, and execution policy

Select compatible Mongock coordinates, wire the runner through Micronaut beans, configure migration scan packages, and decide startup vs controlled-job execution.

Apply framework-aligned migrations

Implement/refactor @ChangeUnit classes with idempotent operations, explicit ordering, rollback hooks, and safe lock/transaction settings.

Run verification and report results

Execute build/tests, including @MicronautTest with Testcontainers MongoDB where feasible, and summarize outcomes and follow-up risks.
