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.

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 provides expertise in Java Generics, enabling the AI agent to write type-safe code and avoid runtime errors. It allows for the creation of generic classes, methods, and interfaces that can operate on different types without sacrificing type safety. The skill also facilitates better code reusability and maintainability through parameterized types.

When to use it

  • Generating Java code snippets that require type safety and flexibility.
  • Debugging existing Java code involving generics and identifying potential type-related issues.
  • Explaining the concepts of generics, wildcards, and bounded parameters in Java.
  • Creating reusable data structures or algorithms that can work with various object types.

Key capabilities

  • Generic classes
  • Generic methods
  • Type inference
  • Wildcard types
  • Bounded type parameters

Example prompts

  • "Write a generic method to find the maximum element in an array of comparable objects."
  • "Explain how wildcard characters work with generics in Java."
  • "Create a generic class for a linked list that can store any type of object."

Tips & gotchas

Requires a foundational understanding of Object-Oriented Programming principles and Java syntax. Generics introduce complexity, so ensure the agent is given clear instructions regarding desired type constraints.
