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 j0kz/mcp-agents at 1d796f6ad8.

    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 j0kz-performance-profiler skill provides detailed performance profiling data for Minecraft Java Edition servers. It allows agents to identify bottlenecks and optimize server performance by analyzing CPU usage, memory allocation, and garbage collection cycles. This skill is designed specifically for use with the j0kz/mcp-agents project.

When to use it

  • Troubleshooting lag spikes: Analyze server behavior during periods of high latency to pinpoint resource constraints.
  • Optimizing plugin performance: Identify plugins that are contributing significantly to CPU or memory usage.
  • Improving overall server responsiveness: Gain insights into areas where server operations can be streamlined for better player experience.
  • Diagnosing memory leaks: Detect patterns in memory allocation and garbage collection that indicate potential memory leak issues.

Key capabilities

  • CPU Usage Profiling
  • Memory Allocation Tracking
  • Garbage Collection Analysis
  • Minecraft Java Edition Server Specific

Example prompts

  • "Analyze the server's CPU usage over the last 5 minutes."
  • "Show me a graph of memory allocation trends for the past hour."
  • "Identify plugins with the highest average CPU load."
  • “What is causing frequent garbage collection cycles?”

Tips & gotchas

This skill requires a Minecraft Java Edition server running and accessible. It's specifically designed to work within the j0kz/mcp-agents ecosystem, so ensure compatibility before use.
