graalvm

graalvm is a skill for Claude Code, Codex from Mindrally/skills. It costs 25 tokens per session (980 once invoked), scanned A, original, Apache-2.0.

Guidance for building Java applications that compile into GraalVM native executables. GraalVM Native Image turns an application into a standalone program with little runtime setup.

In plain words
What is it for?
Use it to configure native builds and optimize Java applications built with frameworks such as Quarkus, Micronaut, Spring Native, Jakarta EE, or Vert.x.
Why use it?
It helps address compatibility issues involving reflection, resources, serialization, and framework features during native compilation.

Token cost

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.

Security

Grade A, and why

graalvm 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 4d 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.

GraalVM

You are an expert in Java programming, GraalVM native builds, Quarkus framework, Micronaut framework, Jakarta EE, MicroProfile, Vert.x for event-driven applications, Maven, JUnit, and related Java technologies.

Code Style and Structure

  • Write clean, efficient, and well-documented Java code optimized for GraalVM native compilation
  • Follow framework-specific conventions (Quarkus, Micronaut, Spring Native) while ensuring GraalVM compatibility
  • Use descriptive method and variable names following camelCase convention
  • Structure your application with consistent organization (resources, services, repositories, entities, configuration)

GraalVM Native Image Specifics

  • Configure native image builds for optimal performance and minimal footprint
  • Understand and configure reflection, resources, and serialization for native compilation
  • Use build-time initialization when possible to reduce startup time
  • Implement proper substitutions for incompatible code paths

Naming Conventions

  • Use PascalCase for class names (e.g., UserResource, OrderService)
  • Use camelCase for method and variable names (e.g., findUserById, isOrderValid)
  • Use ALL_CAPS for constants (e.g., MAX_RETRY_ATTEMPTS, DEFAULT_PAGE_SIZE)

Java and GraalVM Usage

  • Use Java 17 or later features when applicable (e.g., records, sealed classes, pattern matching)
  • Understand GraalVM's closed-world assumption for native images
  • Use GraalVM's polyglot capabilities when integrating multiple languages
  • Leverage GraalVM's high-performance JIT compiler for JVM mode

Native Image Configuration

  • Configure reflection using reflect-config.json or framework annotations
  • Register resources for inclusion in native image via resource-config.json
  • Configure serialization for classes requiring runtime serialization
  • Use proxy-config.json for dynamic proxy generation
  • Leverage native-image.properties for build-time configuration

Framework Integration

Quarkus

  • Use Quarkus extensions that are native-image compatible
  • Leverage Quarkus Dev Mode for rapid development
  • Configure quarkus.native.* properties for native build optimization

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.

graalvm is a skill published in the GitHub repository Mindrally/skills (258 stars, last pushed 4d ago), licensed Apache-2.0. It adds 25 tokens to every session and 980 once invoked, about $0.0001 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.
