SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps teams identify and fix slow frontend experiences, sluggish backend endpoints, and inefficient database queries before they reach production.

Core Features & Use Cases

  • Frontend auditing: Checks Lighthouse scores so teams can spot load-speed and quality regressions early.
  • Backend latency review: Evaluates response-time targets for non-AI and AI endpoints during gate close or pre-deploy reviews.
  • Database performance checks: Flags slow queries, missing foreign-key indexes, and vector index issues that can degrade application performance.
  • Use case: A developer preparing a release can use this Skill to verify that a new endpoint, page, or query change stays within performance thresholds.

Quick Start

Ask the performance skill to audit the current app for frontend, backend, and database bottlenecks before deployment.

Frequently Asked Questions about performance

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I catch performance regressions before deploying my web app?▼

You can audit frontend load speed, backend response time, and database query performance during gate-close reviews to verify Lighthouse scores, latency thresholds, and required indexing before production release.

How do I audit database query performance and check for missing indexes?▼

Auditing database query performance involves flagging slow queries, verifying required foreign-key indexes, and checking vector index issues to prevent SQL workload degradation before deployment.

Can I check Lighthouse score targets for frontend load speed during a pre-deploy review?▼

Yes, frontend auditing checks Lighthouse scores during pre-deploy reviews to spot load-speed and quality regressions early before production deployment.

What is the best way to evaluate backend endpoint latency for AI and non-AI workloads?▼

Evaluating backend latency involves reviewing response-time targets for non-AI and AI endpoints during gate-close or pre-deploy reviews to ensure they stay within acceptable performance thresholds.

Does this performance audit work for both frontend load speed and backend response time?▼

Yes, the performance audit evaluates frontend load speed via Lighthouse scores and backend response time via endpoint latency thresholds, alongside database query efficiency, for comprehensive production readiness.
