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 leavesfly/jimi at 75e1158344.

    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

What it does

This skill assists with Java development by providing guidance on best practices for backend services and APIs. It covers coding conventions, common design patterns, Stream API usage, exception handling, concurrent programming, and Optional usage. The skill aims to improve code quality and maintainability through adherence to established standards.

When to use it

  • When needing help with Java naming conventions (class names, methods, constants, packages).
  • To understand and implement common design patterns like Singleton, Factory, and Builder.
  • For guidance on using the Stream API for data processing.
  • When implementing exception handling strategies in Java code.
  • To ensure correct usage of Optional to handle potential null values.

Key capabilities

  • Naming Conventions: Provides rules for class names (PascalCase), methods/variables (camelCase), constants (UPPER_SNAKE_CASE), and packages (lowercase).
  • Singleton Pattern: Demonstrates implementation using an enum.
  • Factory Pattern: Shows how to create objects based on a type parameter.
  • Builder Pattern: Illustrates building objects with chained method calls.
  • Stream API Usage: Provides examples of filtering and mapping data streams.
  • Exception Handling: Covers best practices for try-catch-finally blocks, including logging and throwing custom exceptions.
  • Concurrent Programming: Shows how to use ExecutorService for asynchronous task execution.
  • Optional Usage: Demonstrates using orElseThrow to handle missing values gracefully.

Example prompts

  • "What is the correct naming convention for a Java constant?"
  • "Show me an example of implementing the Singleton pattern in Java."
  • "How do I use the Stream API to filter and transform a list of users?"
  • “Give me an example of exception handling with logging.”

Tips & gotchas

  • This skill focuses on established Java best practices; ensure these align with your project's specific requirements.
  • The provided examples are illustrative and may need adaptation for your particular use case.
  • Familiarity with basic Java syntax is assumed to effectively utilize this skill’s guidance.
