p90-xray

Analyze real user performance (p90/p95) for a specific route — not averages. This skill maps your route end-to-end (UI → server → DB → external calls), detects tail-latency bottlenecks, and suggests fixes with measurable impact and safety guardrails (so you don’t introduce regressions). If your stack or structure is different, paste this into your AI agent and ask it to adapt the workflow: "Adapt this p90 performance analysis workflow to my tech stack and project structure, then analyze my route and return prioritized bottlenecks with safe, measurable fixes."
