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 jabrena/cursor-rules-java at 8ac07fb219.

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

About this skill

What it does

This skill enables AI agents to write Java code that utilizes functional programming constructs and handles exceptions effectively. It allows for the creation of more concise, readable, and robust Java applications by leveraging lambda expressions, streams, and proper exception management techniques. The skill facilitates cleaner error handling and improved code maintainability within a Java development context.

When to use it

  • Generating utility functions: When you need an AI agent to create helper methods that process collections of data using functional operations (e.g., filtering, mapping).
  • Building microservices: For generating backend services in Java where concise and efficient code is crucial for performance and maintainability.
  • Automating repetitive tasks: When automating the creation of boilerplate Java code involving exception handling and functional programming paradigms.
  • Code refactoring: To assist with modernizing existing Java codebases by introducing functional patterns and improved error management.

Key capabilities

  • Lambda expressions for concise function definitions
  • Java Streams API for data processing
  • Functional interfaces implementation
  • Exception handling best practices (try-catch blocks, custom exceptions)

Example prompts

  • "Write a Java method that uses streams to filter a list of integers and return only the even numbers."
  • "Generate a Java function that reads a file, parses its contents as JSON, and handles potential IOExceptions gracefully using try-catch."
  • "Create a lambda expression in Java that calculates the square of a given number."

Tips & gotchas

  • Requires a foundational understanding of Java syntax and object-oriented programming principles.
  • The agent's output might need review to ensure adherence to specific project coding standards or architectural patterns.
