Test application performance, scalability, and resilience. Use when planning load testing, stress testing, or optimizing system performance.
Expert-level performance optimization, profiling, benchmarking, and tuning
When validating system performance under load, identifying bottlenecks through profiling, or optimizing application responsiveness. Covers load testing (k6, Locust), profiling (CPU, memory, I/O), and optimization strategies (caching, query optimization, Core Web Vitals). Use for capacity planning, regression detection, and establishing performance SLOs.
Thread Dump Analyzer - Auto-activating skill for Performance Testing. Triggers on: thread dump analyzer, thread dump analyzer Part of the Performance Testing skill category.
Quick API endpoint testing with comprehensive request/response validation.
Use when you need to set up JMeter performance testing for a Java project — including creating the run-jmeter.sh script from the exact template, configuring load tests with loops, threads, and ramp-up, or running performance tests from the project root with custom or default settings. Part of the skills-for-java project
k6 performance and load testing. Covers writing test scripts in JavaScript/TypeScript, all test types (load/stress/spike/soak/smoke/breakpoint), thresholds, checks, scenarios, executors, extensions, result analysis, k6 Cloud execution, and CI/CD integration. Use when writing k6 tests, debugging test failures, setting up load testing pipelines, choosing executors/scenarios, or interpreting k6 results.
