403 Frameworks Quarkus Validation is a production-ready Claude Code skill (quality score 70/100) in the network-security sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/403-frameworks-quarkus-validation/ and loads when your prompt matches the skill's trigger.
When to invoke it: 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.
The 403 Frameworks Quarkus Validation skill is built for security engineers, penetration testers, DevSecOps practitioners, and development teams hardening codebases and infrastructure.
