What it does

511 Frameworks Micronaut Jdbc is an agent skill from jabrena/plinth. Use when you need programmatic JDBC in Micronaut — pooled DataSource, parameterized SQL, io.micronaut.transaction.annotation.Transactional, batching, and domain exception translation. This should trigger for requests such as Review JDBC or SQL data access in a Micronaut project; Improve transactions and parameter binding for Micronaut JDBC; Translate SQLException to domain exceptions or stream large result sets; Fix self-invocation bypassing @Transactional in Micronaut; Review Hikari or pooled datasource usage in…

Its SKILL.md is about 870 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/511-frameworks-micronaut-jdbc.md`).

It sits in Databases, covering SQL and Translation. 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 Micronaut — pooled DataSource
  • Parameterized SQL
  • Io.micronaut.transaction.annotation.Transactional
  • Domain exception translation

Example prompts

  • “/511-frameworks-micronaut-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

511 Frameworks Micronaut Jdbc loads about 872 tokens when it runs, and up to ~8.8k if it reads all its reference files. Until then it costs about 147 tokens; SKILL.md has 328 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~147
When it runs · the whole SKILL.md, loaded when a task matches
~872
With references · SKILL.md plus every file in references/, read only if the agent opens them
~8.8k

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.

Micronaut JDBC — programmatic SQL

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

What is covered in this Skill?

  • Injected javax.sql.DataSource (Hikari-backed with micronaut-jdbc-hikari) 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 TransactionDefinition.Propagation (e.g. REQUIRES_NEW for independent commits)
  • Self-invocation pitfall: call transactional collaborators through injected beans, not this.method()
  • SQL text blocks for multi-line SQL (upserts, dialect-specific clauses)
  • When to prefer Micronaut Data (@512) 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 Micronaut project
  • Improve transactions and parameter binding for Micronaut JDBC
  • Translate SQLException to domain exceptions or stream large result sets
  • Fix self-invocation bypassing @Transactional in Micronaut
  • Review Hikari or pooled datasource usage in Micronaut JDBC

Workflow

  1. Read reference and assess project context

Read references/511-frameworks-micronaut-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.
