rcode-perf

What problem does it solve?

This Skill turns vague performance complaints into measurable engineering work, so you can identify the true bottleneck instead of guessing.

Core Features & Use Cases

• Baseline-first workflow: Captures a concrete metric before any change and uses it as the source of truth.
• Stack-specific optimization: Adapts the approach to Next.js web vitals, Three.js frame rates, PostgreSQL query plans, and Vercel or Kubernetes runtime limits.
• Single-change iteration: Applies one targeted fix at a time, then re-measures to verify whether the budget is met.
• Use case: A slow page load, a dropped animation frame rate, or a query that regressed in production can each be diagnosed and improved with the same disciplined loop.

Quick Start

Use the rcode-perf skill to measure the slowest surface, identify one specific bottleneck, apply a single targeted fix, and re-measure until the performance budget is met.
