    Perf Budget Audit Results

    • Severity: HIGH | Rule: INITIAL_JS_BUDGET
    • File: dist/assets/index-D4f2a.js (450KB)
    • Message: Exceeds initial budget of 200KB.
    • Remediation: Use dynamic imports to code-split non-critical modules or check for duplicate dependencies.

    About this skill

    What it does

    Perf Budget Auditor is a specialized developer tool designed to automatically detect frontend performance regressions before they reach production. It scans build artifacts, manifests (stats.json), and asset folders to identify oversized bundles, unoptimized images, leaked source maps, and unminified JavaScript.

    Why use this skill

    Manually checking file sizes after every build is tedious and error-prone. This skill automates the audit process by comparing your build output against defined performance budgets (perf-budget.json). It provides actionable remediation guidance rather than just raw numbers, helping developers pinpoint exactly which chunks or assets are bloating the application.

    Supported tools

    • Standard web build folders (dist, build, out)
    • Webpack/Rollup/Vite manifest files (stats.json)
    • Custom performance budget configurations
    • Common frontend assets (JS, CSS, WASM, Images)

    Output Expected

    You will receive a structured report detailing the inspected scope, specific rule violations, severity levels, and precise file paths. Each finding includes "evidence" (e.g., actual size vs. budget) and clear remediation steps to fix the bloat.

    I already had a forecasting tool but this gave us more detail that I had Claude take the best parts and merge it into my current agent to make it more robust.

    JustHandled Labs builds focused agent skills for the work nobody wants to do by hand. Each one is a single repeatable job done well: catching the security and data mistakes that quietly ship, keeping docs and tests honest, gating the commands an agent is about to run, sharpening writing, and handling the founder chores around launches, outreach, and brand setup. Not generic AI productivity. Specific workflows that are easy to run, review, and repeat. Maintained by H.J. Westerfield, with a background in communications, editing, project coordination, customer support, and practical AI systems. Tools for people who want useful automation without theatrical complexity.
