Tracks JavaScript bundle sizes over time and blocks merges that exceed defined budgets.
Overview
This specialized agent continuously monitors the JavaScript bundle sizes within your development pipeline. Leveraging sophisticated size tracking capabilities, it meticulously records and analyzes the impact of every code change on your application's overall footprint, ensuring that performance remains a top priority from commit to deployment. It provides granular insights into which files or components contribute most to the bundle size.
Beyond mere observation, the monitor actively enforces predefined size budgets. When a pull request introduces changes that would push your bundle over an acceptable threshold, it automatically blocks the merge, preventing performance regressions before they ever reach your main branch. This proactive budget enforcement mechanism safeguards your user experience and keeps your application lean.
Furthermore, the Agentik OS Bundle Size Monitor offers insightful trend analysis, visualizing how your bundle size evolves over time. It annotates pull requests directly with crucial size metrics and warnings, empowering developers with immediate feedback and fostering a culture of performance awareness. This integration streamlines the identification of potential issues and encourages optimization at every stage.

Process
Bundle Size Monitor 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
Automatically block pull requests that increase your JavaScript bundle size beyond a set limit, ensuring consistent application performance and preventing regressions.
Gain insights into how individual code changes or new features impact your bundle size, helping developers pinpoint and address performance bottlenecks early.
Track and visualize your JavaScript bundle size trends over weeks or months, enabling data-driven decisions for long-term optimization strategies.
Receive immediate, automated feedback on bundle size changes directly within your pull request, making performance considerations an integral part of every code review.
