What it does

403 Frameworks Quarkus Validation is an agent skill from jabrena/plinth. 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…

Its SKILL.md is about 680 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/403-frameworks-quarkus-validation.md`).

It sits in Backend & APIs, covering REST APIs, Deep learning and Design review and critique. The repository describes itself as: Plinth is an AI-native engineering toolkit for modern Java enterprise SDLC, built around reusable Commands, Agents, Skills, and MCP Servers. The licence is Apache-2.0.

When your agent uses it

  • You need to design
  • Improve validation in Quarkus applications — including Bean Validation on JAX-RS resources
  • @Valid on parameters and CDI beans
  • Constraint groups

Example prompts

  • “/403-frameworks-quarkus-validation”

What it can do on your machine

Read from SKILL.md and the folder at commit dca88dc. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • mvn

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

403 Frameworks Quarkus Validation loads about 684 tokens when it runs, and up to ~3.1k if it reads all its reference files. Until then it costs about 151 tokens; SKILL.md has 238 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~151
When it runs · the whole SKILL.md, loaded when a task matches
~684
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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 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 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

  1. Read reference and assess project context

Read references/403-frameworks-quarkus-validation.md and inspect the current project setup before proposing changes.

  1. Gather scope and decide target improvements

Identify requested outcomes, constraints, and the minimum safe set of changes to apply.

  1. Apply framework-aligned changes

Implement or refactor validation-related configuration/code following the reference patterns and project conventions.

  1. Run verification and report results

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