Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00112 | $0.00723 |
| Opus 5 | $0.00056 | $0.00362 |
| Sonnet 5 | $0.00022 | $0.00145 |
| Haiku 4.5 | $0.00011 | $0.00072 |
Grade A, and why
411-frameworks-quarkus-jdbc scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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; 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 compileormvn compilebefore 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 verifyormvn clean verifyafter 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
- Read reference and assess project context
Read references/411-frameworks-quarkus-jdbc.md and inspect the current project setup before proposing changes.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

411-frameworks-quarkus-jdbc is a skill published in the GitHub repository jabrena/plinth (438 stars, last pushed today), licensed Apache-2.0. It adds 112 tokens to every session and 723 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
