At a glance

A skill your agent uses when you need programmatic JDBC in Quarkus — Agroal DataSource, parameterized SQL, transactions, batching, and Dev Services.

  • You need programmatic JDBC in Quarkus — Agroal DataSource
  • SKILL.md covers Constraints, When to use this skill, Workflow and Reference
  • Calls mvn
  • Parameterized SQL

What it does

411 Frameworks Quarkus Jdbc is an agent skill from jabrena/plinth. Use when you need programmatic JDBC in Quarkus — Agroal DataSource, parameterized SQL, transactions, batching, and Dev Services. This should trigger for requests such as Review JDBC or SQL data access in a Quarkus project; Improve transactions and parameter binding for Quarkus JDBC; Translate SQLException to domain exceptions or stream large result sets; Fix CDI self-invocation bypassing @Transactional in Quarkus; Review Agroal DataSource usage in Quarkus JDBC. Part of Plinth Toolkit

Its SKILL.md is about 830 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/411-frameworks-quarkus-jdbc.md`).

It sits in Databases, covering SQL. It works with SQL. 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 programmatic JDBC in Quarkus — Agroal DataSource
  • Parameterized SQL
  • Requests such as Review JDBC
  • SQL data access in a Quarkus project

Example prompts

  • “/411-frameworks-quarkus-jdbc”

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

411 Frameworks Quarkus Jdbc loads about 826 tokens when it runs, and up to ~8.7k if it reads all its reference files. Until then it costs about 129 tokens; SKILL.md has 322 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~129
When it runs · the whole SKILL.md, loaded when a task matches
~826
With references · SKILL.md plus every file in references/, read only if the agent opens them
~8.7k

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 JDBC — programmatic SQL

Apply programmatic JDBC patterns in Quarkus with safe SQL and clear transactions.

What is covered in this Skill?

  • Injected javax.sql.DataSource (Agroal-backed) and try-with-resources for Connection / PreparedStatement
  • PreparedStatement with bind parameters — never string concatenation
  • Mapping ResultSet rows to Java records (dedicated mapRow method)
  • Safe single-row queries with Optional<T>; never assume rs.next() succeeds
  • SQLException translation to domain exceptions (catch-translate-rethrow)
  • Streaming large result sets with setFetchSize to avoid OOM
  • Batch updates with addBatch / executeBatch for bulk inserts
  • @Transactional service boundaries and propagation types (TxType.REQUIRES_NEW for independent commits)
  • CDI self-invocation pitfall: always call transactional methods through the injected proxy
  • Dev Services for databases in dev/test
  • When to prefer Panache (@412) vs raw JDBC

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

Constraints

Compile before JDBC refactors; verify after changes.

  • MANDATORY: Run ./mvnw compile or mvn compile before applying any change
  • PREREQUISITE: Project must compile before applying JDBC improvements
  • SAFETY: If compilation fails, stop immediately
  • BLOCKING CONDITION: Compilation errors must be resolved by the user before proceeding
  • 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

  • Review JDBC or SQL data access in a Quarkus project
  • Improve transactions and parameter binding for Quarkus JDBC
  • Translate SQLException to domain exceptions or stream large result sets
  • Fix CDI self-invocation bypassing @Transactional in Quarkus
  • Review Agroal DataSource usage in Quarkus JDBC

Workflow

  1. Read reference and assess project context

Read references/411-frameworks-quarkus-jdbc.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 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.
