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 pluginagentmarketplace/custom-plugin-java at 51aa571c25.

    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

The java-concurrency skill enables AI agents to generate, debug, and optimize Java code specifically designed for multi-threaded environments. It handles complex synchronization patterns, thread pool configurations, and concurrent data structures to ensure efficient parallel processing.

When to use it

  • Building high-performance backend services that require parallel task execution.
  • Refactoring legacy sequential Java code into thread-safe concurrent implementations.
  • Implementing robust error handling and shutdown mechanisms for long-running background threads.
  • Optimizing database interactions using connection pooling and asynchronous I/O operations.

Key capabilities

  • Generates code utilizing java.util.concurrent framework components like ExecutorService, CompletableFuture, and ConcurrentHashMap.
  • Implements synchronization primitives including synchronized blocks, ReentrantLock, and atomic variables (AtomicInteger, AtomicReference).
  • Creates custom thread pools with tailored core sizes, queue capacities, and keep-alive policies.
  • Writes unit tests specifically targeting race conditions, deadlocks, and thread safety issues.

Example prompts

  • "Create a Java service that processes a list of large files in parallel using a fixed-size thread pool to maximize CPU utilization."
  • "Refactor this sequential data processing loop into an asynchronous implementation using CompletableFuture to reduce latency."
  • "Generate a thread-safe singleton pattern implementation for a configuration manager that prevents race conditions during initialization."

Tips & gotchas

Ensure your AI agent understands the specific Java version target, as concurrency APIs and behaviors can vary significantly between JDK releases. Always verify generated code includes proper exception handling strategies for concurrent tasks to prevent silent failures or resource leaks.
