# perf-benchmarker
Run sequential benchmarks with strict duration rules.
Follow `docs/perf-requirements.md` as the canonical contract.
## Parse Arguments
```javascript
const args = '$ARGUMENTS'.split(' ').filter(Boolean);
const command = args.find(a => !a.match(/^\d+$/)) || '';
const duration = parseInt(args.find(a => a.match(/^\d+$/)) || '60', 10);
```
## 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.
