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 | $0.00117 | $0.00764 |
| Opus 5 | $0.00059 | $0.00382 |
| Sonnet 5 | $0.00023 | $0.00153 |
| Haiku 4.5 | $0.00012 | $0.00076 |
Grade A, and why
401-frameworks-quarkus-core 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 6d 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 Core Guidelines
Apply Quarkus core guidelines for CDI beans, configuration, profiles, and lifecycle.
What is covered in this Skill?
- @QuarkusMain and application entry (when custom main is needed)
- CDI scopes: @ApplicationScoped, @Singleton, @Dependent; bean disambiguation (@Default, @Alternative, @Named)
- Constructor injection with @Inject
- CDI interceptors (@Interceptor, @InterceptorBinding) for cross-cutting concerns
- CDI events: @Observes StartupEvent / ShutdownEvent, @ObservesAsync for async dispatch
- Programmatic injection with Instance for dynamic bean selection
- @ConfigMapping and structured configuration with Bean Validation (@Valid)
- Profile-specific properties (%dev, %test, %prod) and @IfBuildProfile
- Startup and shutdown observers (@Startup, @PreDestroy)
- Virtual threads with @RunOnVirtualThread (Java 21+)
- Native-image safety: @RegisterForReflection, @DisabledOnNativeImage
Scope: Apply recommendations based on the reference rules and good/bad code examples.
Constraints
Before applying any Quarkus changes, ensure the project compiles. If compilation fails, stop immediately. After applying improvements, run full verification.
- MANDATORY: Run
./mvnw compileormvn compilebefore applying any change - PREREQUISITE: Project must compile successfully before applying Quarkus core improvements
- SAFETY: If compilation fails, stop immediately — compilation failure is a blocking condition
- 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, good/bad patterns, and constraints
When to use this skill
- Review Java code for Quarkus application structure and CDI
- Apply best practices for Quarkus configuration and beans
- Improve CDI interceptors, events, or programmatic injection in Quarkus
- Add virtual-thread configuration or tune CDI lifecycle
- Review Quarkus CDI bean lifecycle and configuration
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.

401-frameworks-quarkus-core is a skill published in the GitHub repository jabrena/plinth (437 stars, last pushed yesterday), licensed Apache-2.0. It adds 117 tokens to every session and 764 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.
