Runs load and stress tests with k6 or Artillery to measure throughput, latency, and breaking points.
Overview
This specialized quality agent is adept at rigorously evaluating system performance under duress. It orchestrates comprehensive load and stress tests using industry-standard tools like k6 and Artillery, meticulously simulating high user traffic and complex request patterns. Its core function is to push applications to their limits, revealing critical bottlenecks and performance degradation before they impact end-users.
Leveraging its expertise in k6 scripting, the agent can design and execute highly customized test scenarios tailored to specific application architectures and business logic. It precisely measures key performance indicators such as throughput, response times, and error rates, providing granular data on how well a system handles varying levels of concurrent users and data volumes.
Furthermore, this agent excels in breaking point analysis, systematically increasing load until system failures or unacceptable performance thresholds are reached. By identifying these breaking points, it provides invaluable insights into system scalability and resilience, empowering development teams to proactively optimize infrastructure and code for robust, high-performance operations.

Process
Load Tester follows a systematic process to deliver consistent, high-quality results.
Crawls your application to map every page, route, form, and interactive element. Builds a complete sitemap of testable surfaces.
Creates comprehensive test scenarios covering user flows, edge cases, and regression paths based on the discovered application structure.
Runs all test scenarios across browsers and viewports, capturing screenshots, console logs, and network requests at each step.
Generates a detailed report classifying issues by severity (CRITICAL/HIGH/MEDIUM/LOW) with reproduction steps and fix suggestions.
Use Cases
Before a major software release, this agent rigorously tests the application's stability and speed under peak expected load, ensuring a smooth launch without performance issues. It identifies potential bottlenecks that could arise from increased user traffic.
The agent can be deployed to stress test critical APIs, measuring their throughput and latency under heavy concurrent requests. This helps determine the API's capacity and identifies areas for optimization to handle future growth.
By systematically increasing load, this agent uncovers the exact point at which your current infrastructure (servers, databases, network) begins to degrade or fail. This data is crucial for informed scaling decisions and capacity planning.
Integrated into CI/CD pipelines, the agent automatically runs load tests on new code deployments to detect any performance regressions. It ensures that new features or bug fixes don't inadvertently impact system speed or stability.
Capabilities
DIY Guide
Follow these steps to create a similar agent for your own workflow — or let us handle it for you.
Define what to test — UI, API, performance, security, or all of the above. Each scope requires different tooling and configuration.
Build an automated crawler that discovers all routes, forms, and interactive elements in your application.
Create test case generators that produce scenarios from your application map, covering happy paths, edge cases, and failure modes.
Set up parallel test execution with screenshot capture, network logging, and console monitoring across multiple browsers.
Build a reporting system that classifies findings by severity, includes reproduction steps, and generates fix suggestions.
