What problem does it solve?

This Skill helps you systematically diagnose slow systems and performance regressions by turning vague “it’s slow” complaints into measurable bottleneck hypotheses.

Core Features & Use Cases

  • Structured bottleneck discovery (USE Method): Evaluate utilization, saturation, and errors across resources such as CPU, memory, disk, and network.
  • Service-level latency diagnosis (RED Method): Analyze request rate, error rate, and latency duration percentiles for services and microservices.
  • Thread and CPU hot-spot visibility (TSA + Flame graphs): Break down time spent across OS thread states and visualize CPU stack hotspots to find what code paths consume time.
  • Workflow support: Provides problem-statement framing, workload characterization, drill-down analysis, and elimination-based root-cause testing, plus anti-methodologies to avoid.

Quick Start

Ask your AI to apply the USE method to identify CPU, memory, disk, or network bottlenecks and then use flame-graph guidance to pinpoint the hot code paths causing the slowdown.
