performance-test-harness

What problem does it solve?

This Skill designs the measurement harness that proves whether software got slower, replacing guesswork with reproducible performance evidence.

Core Features & Use Cases

• Surface-specific measurement design: Defines what to measure for APIs, database queries, frontend pages, jobs, and edge functions.
• Environment contracts and baselines: Requires pinned hardware, declared cache state, representative data volume, and versioned baselines so results are comparable.
• Variance-aware regression gates: Uses repeated runs, noise bands, and CI tiers to detect real regressions without relying on single-run diffs.
• Honest reporting: Stamps conditions on every result, reports UNRUN clearly, and keeps production load tests approval-gated.
• Use case: A team needs to catch a slower release before it reaches customers and wants a reliable nightly and pre-release perf gate.

Quick Start

Ask for a performance test harness design for your product that names the measured surfaces, environment contract, baseline rules, variance-aware detection, and CI gating.
