One thing to look at

no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.

What its author says it does

Copied from the file, not written here

Use when running performance benchmarks, establishing baselines, or validating regressions with sequential runs. Enforces 60s minimum runs (30s only for binary search) and no parallel benchmarks.

SKILL.md

1.0 KB, as published. Nobody here has run it

perf-benchmarker

Run sequential benchmarks with strict duration rules.

Follow docs/perf-requirements.md as the canonical contract.

Required Rules

Benchmarks MUST run sequentially (never parallel).
Minimum duration: 60s per run (30s only for binary search).
Warmup: 10s minimum before measurement.
Re-run anomalies.

Output Format

command: <benchmark command>
duration: <seconds>
warmup: <seconds>
results: <metrics summary>
notes: <anomalies or reruns>

Output Contract

Benchmarks MUST emit a JSON metrics block between markers:

PERF_METRICS_START
{"scenarios":{"low":{"latency_ms":120},"high":{"latency_ms":450}}}
PERF_METRICS_END

Constraints

No short runs unless binary-search phase.
Do not change code while benchmarking.
