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 | $0.00075 | $0.04380 |
| Opus 5 | $0.00037 | $0.02190 |
| Sonnet 5 | $0.00015 | $0.00876 |
| Haiku 4.5 | $0.00007 | $0.00438 |
Grade A, and why
quarkus-backend 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 10d 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.

Quarkus Backend
Purpose
Define Quarkus backend application architecture: supersonic startup, live reload, native executables, reactive messaging, and extension ecosystem.
Agent Protocol
Trigger
User request includes: quarkus, quarkus backend, supersonic java, quarkus native, panache, quarkus reactive, quarkus extension, quarkus dev ui, container-first java.
Input Context
- JDK version (17+)
- Build tool (Gradle, Maven)
- Runtime (JIT, GraalVM native)
- Extensions (RESTEasy Reactive, Hibernate, Kafka, MongoDB)
- Deployment (JAR, native binary, container)
Output Artifact
A markdown document containing:
- Project structure
- RESTEasy Reactive endpoint conventions
- Panache ORM setup
- Reactive messaging configuration
- Dev Services and Dev UI usage
- Native compilation config
- Testing with @QuarkusTest
- Extension configuration
Response Format
Produce the artifact directly. No preamble, no postamble, no explanations. No filler, no hedging. Compress output.
Completion Criteria
- Application starts in dev mode with live reload
- REST endpoints use RESTEasy Reactive annotations
- Panache repository or active record configured
- Native build succeeds with application.properties tuning
- Tests pass with @QuarkusTest and Dev Services
Max Response Length
4096 tokens
Workflow
Step 1: Project Initialization
# Using Maven
mvn io.quarkus.platform:quarkus-maven-plugin:3.6.0:create \
-DprojectGroupId=com.example \
-DprojectArtifactId=order-service \
-Dextensions='resteasy-reactive,hibernate-validator,reactive-pg-client,panache'
# Using Gradle
quarkus create app com.example:order-service \
--extension=resteasy-reactive,reactive-pg-client,panache,kafka
# Using Quarkus CLI
quarkus create app order-service \
-x resteasy-reactive,reactive-pg-client,panache,kafka

What ships with it
6 files 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.

quarkus-backend is a skill published in the GitHub repository j4flmao/agent-skills (22 stars, last pushed 3d ago), licensed MIT. It adds 75 tokens to every session and 4,380 once invoked, about $0.0004 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 2026-08-30.
