java-foundation

A shared set of Java development rules for projects using the Java Virtual Machine, including coding style, build tools, dependencies, and testing.

In plain words
What is it for?
Use it as a base for Java projects with Maven or Gradle and tests using tools such as JUnit, Mockito, AssertJ, or Testcontainers.
Why use it?
It gives Java framework-specific add-ons a common foundation for readable code, consistent builds, and reliable tests.

Grade A, and why

java-foundation 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 2d 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.

  "name": "java-foundation",
  "version": "1.3.0",
  "description": "Shared Java foundation skills for the SDLC marketplace. Contains stack-agnostic conventions: java-conventions (modern Java idioms — records, sealed types, Optional, streams, immutability, null discipline), build-tooling (Maven vs Gradle detection, wrappers, dependency/BOM management, semver) and jvm-testing (JUnit 5, Mockito, AssertJ, Testcontainers). Referenced cross-plugin by every Java framework provider (java-plugin, spring-boot-plugin). No agent, no stack profile — pure shared library.",

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.
