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 poletron/custom-rules at aba6668777.

    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

The poletron-java skill allows AI agents to execute Java code snippets. It provides a runtime environment for running Java, enabling tasks like data manipulation, calculations, and interacting with external APIs through Java libraries. The agent can receive Java code as input and return the output of its execution.

When to use it

  • Data Transformation: Use this skill when you need to perform complex data transformations that are easier or more efficient in Java than in other languages.
  • API Interaction: Leverage existing Java libraries to interact with specific APIs or services where a Java client library is readily available.
  • Complex Calculations: Execute computationally intensive tasks or algorithms best implemented in Java.
  • Code Execution: Run small code snippets for quick calculations and data processing.

Key capabilities

  • Java Code Execution: Executes provided Java code snippets.
  • Runtime Environment: Provides a Java runtime environment within the agent.
  • Output Handling: Returns the output of executed Java code.
  • Library Support: Supports use of standard Java libraries.

Example prompts

  • "Run this Java code: System.out.println(2 + 2);"
  • "Calculate the factorial of 5 using Java."
  • "Use Java to convert this JSON string into a map: { 'name': 'John', 'age': 30 }"

Tips & gotchas

  • The skill requires basic knowledge of Java syntax and programming concepts.
  • Keep code snippets concise for optimal performance and avoid complex dependencies.
