403-frameworks-quarkus-validation
Use when you need to design, review, or improve validation in Quarkus applications — including Bean Validation on JAX-RS resources, @Valid on parameters and CDI beans, constraint groups, @ConfigMapping validation, custom constraints, nested DTO validation, and ExceptionMapper-based error mapping. This should trigger for requests such as Add validation support in Quarkus; Review Quarkus validation rules; Improve request validation in Quarkus REST APIs; Add custom validation constraints in Quarkus; Validate Quarkus @ConfigMapping properties.

What does this agent skill do?
Quarkus Validation Guidelines
Apply Quarkus validation best practices at REST boundaries.
What is covered in this Skill?
- Bean Validation annotations on DTOs and command models
- @Valid and boundary validation in Jakarta REST resources
- Validation groups and custom constraints
- Validation error mapping for client-safe responses
- Consistent handling of invalid inputs across endpoints
Scope: Apply recommendations based on the reference rules and good/bad examples.
Constraints
Before applying validation changes, ensure the project compiles. After improvements, run full verification.
- MANDATORY: Run
./mvnw compileormvn compilebefore applying any change - SAFETY: If compilation fails, stop immediately
- VERIFY: Run
./mvnw clean verifyormvn clean verifyafter applying improvements - BEFORE APPLYING: Read the reference for detailed rules and examples
When to use this skill
- Add validation support in Quarkus
- Review Quarkus validation rules
- Improve request validation in Quarkus REST APIs
- Add custom validation constraints in Quarkus
- Validate Quarkus @ConfigMapping properties
- Improve validation error mapping with ExceptionMapper in Quarkus
Workflow
- Read reference and assess project context
Read references/403-frameworks-quarkus-validation.md and inspect the current project setup before proposing changes.
- Gather scope and decide target improvements
Identify requested outcomes, constraints, and the minimum safe set of changes to apply.
- Apply framework-aligned changes
Implement or refactor validation-related configuration/code following the reference patterns and project conventions.
- Run verification and report results
Execute appropriate build/tests and summarize what changed, what was verified, and any follow-up actions.
