Install target

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 spjoshis/claude-code-plugins at ddcf16ef7b.

    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 allows you to generate performance testing scripts. It can create load tests, stress tests, and endurance tests for various applications and systems. The generated scripts are designed to simulate user traffic and identify bottlenecks or areas of improvement in application performance.

When to use it

  • Load Testing a New Feature: Before releasing a new feature, generate a load test to ensure it can handle expected user traffic.
  • Identifying Performance Bottlenecks: Run stress tests on existing systems to pinpoint areas causing slowdowns or errors under high load.
  • Endurance Testing for Stability: Create endurance tests to evaluate the long-term stability and resource usage of an application over extended periods.
  • Validating Infrastructure Changes: After making changes to your infrastructure (e.g., scaling servers), use performance testing to confirm that the changes have improved or at least not negatively impacted performance.

Key capabilities

  • Generate load tests
  • Create stress tests
  • Produce endurance tests
  • Simulate user traffic
  • Identify performance bottlenecks

Example prompts

  • "Create a load test script for my e-commerce website, simulating 100 concurrent users browsing products and adding items to their cart."
  • "Generate a stress test to determine the breaking point of my API endpoint that handles image uploads."
  • “Develop an endurance test script to monitor memory usage of our database server over 24 hours.”

Tips & gotchas

The quality of the generated scripts depends on the clarity and detail provided in your prompts. Be specific about the application, expected user behavior, and performance goals for best results.
