Use when validating application performance under load conditions or identifying bottlenecks. Trigger with phrases like "run load test", "create stress test", or "validate performance under load". version: 1.21.0 allowed-tools: Read, Write, Edit, Grep, Glob, Bash(k6:*), Bash(jmeter:*), Bash(artillery:*), Bash(performance:*) license: MIT author: Jeremy Longshore tags: - performance - testing - load-tests compatibility: Designed for Claude Code --- # Load Test Runner Create and execute load tests using k6, JMeter, and Artillery to validate application performance under stress, spike, soak, and scalability scenarios. ## Overview This skill empowers Claude to automate the creation and execution of load tests, ensuring applications can handle expected traffic and identify potential performance bottlenecks. It streamlines the process of defining test scenarios, generating scripts, and executing tests for comprehensive performance validation. ## How It Works 1. **Analyze Application**: Claude analyzes the user's request to understand the application's endpoints and critical paths. 2. **Identify Test Scenarios**: Claude identifies relevant test scenarios, such as baseline load, stress test, spike test, soak test, or scalability test, based on the user's requirements. 3. **Generate Load Test Scripts**: Claude generates load test scripts (k6, JMeter, Artillery, etc.) based on the selected scenarios and application details. 4. **Define Performance Thresholds**: Claude defines performance thresholds and provides execution instructions for the generated scripts. ## When to Use This Skill This skill activates when you need to: - Create load tests for a web application or API. - Validate the performance of an application under different load conditions. - Identify performance bottlenecks and breaking points. ## Examples ### Example 1: Creating a Stress Test User request: "Create a stress test for the /api/users endpoint to simulate 1000 concurrent users." The skill will: 1. Analyze the request and identify the need for a stress test on the /api/users endpoint. 2. Generate a k6 script that simulates 1000 concurrent users hitting the /api/users endpoint. ### Example 2: Validating Performance After a Code Change User request: "Validate the performance of the application after the recent code changes with a baseline load test." The skill will: 1. Identify the need for a baseline load test to validate performance. 2. Generate a JMeter script that simulates normal traffic patterns for the application. ## Best Practices - **Realistic Scenarios**: Define load test scenarios that accurately reflect real-world usage patterns. - **Threshold Definition**: Establish clear performance thresholds to identify potential issues. - **Iterative Testing**: Run load tests iteratively to identify and address performance bottlenecks early in the development cycle. ## Integration This skill can be integrated with CI/CD pipelines to automate performance testing as part of the deployment process. It can also be used in conjunction with monitoring tools to correlate performance metrics with application behavior. ## Prerequisites - Load testing tools installed (k6, JMeter, or Artillery) - Access to target application endpoints - Test scenario definitions and expected load patterns - Results storage location at ${CLAUDE_SKILL_DIR}/load-tests/ ## Instructions 1. Analyze application architecture and identify critical endpoints 2. Define test scenarios (baseline, stress, spike, soak, scalability) 3. Generate appropriate load test scripts using selected tool 4. Configure performance thresholds and acceptance criteria 5. Execute load tests and capture metrics 6. Analyze results and identify performance bottlenecks ## Output - Load test scripts (k6, JMeter, or Artillery format) - Test execution logs and metrics - Performance reports with response times and throughput - Threshold violation alerts - Recommendations for performance improvements ## Error Handling If load test execution fails: - Verify tool installation and configuration - Check network connectivity to target endpoints - Validate authentication and authorization - Review test script syntax and parameters - Ensure sufficient system resources for test execution ## Resources - k6 documentation and examples - JMeter user manual and best practices - Artillery load testing guides - Performance testing methodology references --- Source attribution: jeremylongshore Original project: https://github.com/jeremylongshore/claude-code-plugins-plus-skills/blob/ab85a061f7bcc039dac13ee193de7a4cd4388571/plugins/performance/load-test-runner/skills/running-load-tests/SKILL.md License: MIT License information: https://opensource.org/license/mit Original upstream instructions; downloaded from Mega AI Hub. ## Upstream license notice MIT License Copyright (c) 2026 Claude Code Plugins Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
