Micronaut — MongoDB

Apply Micronaut MongoDB guidance with concrete examples for design, implementation, and error handling.

Constraints

Compile before MongoDB refactors; 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 examples

When to use this skill

• Add MongoDB in Micronaut
• Review Micronaut Mongo entities/repositories
• Improve duplicate key handling, retries, or optimistic locking in Micronaut Mongo

Workflow

1. Read reference and assess project context

Read references/515-frameworks-micronaut-mongodb.md and inspect persistence setup before proposing changes.

2. Gather scope and decide target improvements

Identify model and consistency requirements and define safe improvements.

3. Apply framework-aligned changes

Implement/refactor documents, repositories, indexes, and error handling.

4. Run verification and report results

Execute build/tests and summarize what changed, what was verified, and follow-up actions.
