Perf Benchmarker
If you're chasing down performance regressions or establishing real baselines, this enforces the discipline most benchmark scripts skip. It mandates 60 second runs with proper warmup, blocks parallel execution that pollutes results, and makes you re-run anomalies instead of cherry-picking good data. The tool expects structured JSON output between markers and won't let you take shortcuts with quick 5-second tests unless you're actively binary-searching for a threshold. It's opinionated about measurement rigor, which is exactly what you need when numbers actually matter for production decisions.

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.
