Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned mindrally/skills at 7682ca7771.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

The Java skill enables AI agents to write, compile, and execute code within the Java ecosystem. It allows for building robust backend services, automating complex data processing tasks, and integrating with enterprise-grade libraries.

When to use it

  • Developing high-performance microservices or APIs that require strong typing and memory management.
  • Automating legacy system migrations or interacting with existing Java-based enterprise infrastructure.
  • Generating unit tests using frameworks like JUnit to ensure code reliability before deployment.
  • Creating command-line tools or batch scripts for heavy data transformation workflows.

Key capabilities

  • Writing standard Java classes, interfaces, and packages.
  • Utilizing core libraries for file I/O, networking, and database connectivity (JDBC).
  • Implementing logic with Spring Boot, Hibernate, or other popular frameworks.
  • Handling exception management and resource cleanup automatically.

Example prompts

  • "Generate a Java class that connects to a PostgreSQL database and retrieves user records."
  • "Write a Spring Boot REST controller that accepts JSON input and returns a processed response."
  • "Create a utility method to parse CSV files and convert them into a list of objects."

Tips & gotchas

Ensure your AI agent has access to a Java runtime environment (JRE) or a build tool like Maven/Gradle to execute the generated code. Complex dependencies may require explicit instructions on how to resolve versions within the project structure.
