claude-code-java

claude-code-java is a skill for Claude Code, Codex from autohandai/community-skills. It costs 25 tokens per session (345 once invoked), scanned A, original, Apache-2.0.

A guide for using coding-agent support in Java projects, covering project conventions, testing, refactoring, and migrations.

In plain words
What is it for?
Use it to inspect Maven or Gradle projects, plan version migrations, preserve public behavior, and validate compilation, tests, formatting, and static analysis.
Why use it?
It gives an agent a structured way to work within existing Java build tools, packages, APIs, configuration, and framework assumptions.

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

claude-code-java 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 9d 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.

What it actually says

claude-code-java

Overview

Use this skill when a Java project needs reusable coding-agent infrastructure from decebals/claude-code-java. The upstream project is optimized for Claude Code but its conventions are useful for Java agent workflows generally.

Compatibility: Java, Maven, Gradle, testing, refactoring, migration, and Claude Code-style workflows.

Workflow

  1. Identify the Java version, build tool, framework, module layout, and test stack.
  2. Inspect upstream instructions before importing conventions into the local repository.
  3. Keep work tool-native: use Maven or Gradle commands already present in the project.
  4. For migration tasks, define the source and target versions, dependency changes, and compatibility risks first.
  5. Validate compile, tests, formatting, and static analysis according to the local project.

Guardrails

  • Do not mix Maven and Gradle patterns unless the repository already does.
  • Preserve package names, public APIs, serialization contracts, and configuration keys.
  • Keep framework-specific assumptions explicit, especially for Spring Boot, Quarkus, Jakarta EE, and Micronaut.
  • Treat generated agent instructions as project support material, not application runtime code.

Expected Output

Return Java-focused implementation or migration guidance with build commands, risk notes, and validation evidence.

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.
