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 enables AI agents to write Java code using a data-oriented programming (DOP) approach. It focuses on structuring applications around data transformations and minimizing mutable state, leading to more predictable and performant systems. The skill facilitates the creation of efficient algorithms by prioritizing data layout and access patterns.

When to use it

  • Performance optimization: When existing Java code is slow or resource-intensive due to excessive object manipulation.
  • Data processing pipelines: For building applications that involve complex transformations of large datasets, such as image processing or financial analysis.
  • Game development: To create efficient game logic and simulations by optimizing data structures for rapid access.
  • High-frequency trading systems: Where low latency and predictable execution are critical.

Key capabilities

  • Data-oriented Java code generation
  • Focus on immutable data structures
  • Emphasis on data layout optimization
  • Minimization of mutable state

Example prompts

  • "Write a Java function to sort this list of customer records using a DOP approach."
  • "Generate a data-oriented implementation for calculating the shortest path in a graph."
  • "Create a Java class representing a 2D grid with immutable cells, optimized for spatial queries."

Tips & gotchas

  • Requires familiarity with core Java programming concepts.
  • The generated code may require adjustments to integrate seamlessly into existing projects due to its distinct style.
