Why does the skill enforce a 60-second minimum run?

Longer run times minimize the impact of transient system noise and ensure the resulting metrics represent a statistically significant steady state of the application.

What format are the results provided in?

Benchmarks emit a standardized JSON metrics block between specific markers (PERF_METRICS_START and PERF_METRICS_END) for consistent data parsing.

Can I modify code while a benchmark is active?

No, the skill requires that no code changes be made during the benchmarking process to ensure the integrity and repeatability of the results.

Is there a warmup period included?

Yes, a minimum 10-second warmup period is required before measurements begin to allow for JIT compilation, cache warming, or connection pooling.

Security & Testing

Conducts standardized performance benchmarks with strict duration rules to ensure accurate baselines and regression detection.

The Performance Benchmarker skill automates the process of running consistent, high-fidelity benchmarks within your development environment. It enforces industry best practices by requiring sequential runs, minimum 60-second durations, and mandatory 10-second warmups to eliminate environmental noise and anomalies. This skill is essential for developers who need to establish reliable performance baselines, validate hardware-specific regressions, or perform binary search optimizations while ensuring metrics are captured in a standardized JSON format for automated analysis.
