sigrank-standard (Python)
Portable five-metric core for AI operator token-processing efficiency.
Install
pip install sigrank-standard
Usage
Compute metrics
from sigrank_standard import compute_metrics, build_record
# Four token pillars: input, output, cache_write, cache_read
result = compute_metrics(
input_tokens=1_251_211,
output_tokens=11_296_121,
cache_write=128_196_310,
cache_read=2_555_179_769,
)
print(result["metrics"])
# {'yield': 18436.98, 'leverage': 2042.2, 'velocity': 9.028, 'snr': 0.9, 'dev10x': 3.31}
Build a full record
from sigrank_standard import build_record
import json
record = build_record(
input_tokens=1_251_211,
output_tokens=11_296_121,
cache_write=128_196_310,
cache_read=2_555_179_769,
provider="anthropic",
model="claude-sonnet-4",
tool="claude-code",
)
print(json.dumps(record, indent=2))

Metrics
| Metric | Formula | Description |
|---|---|---|
| Yield (Υ) | (cache_read * output) / input^2 |
Token cascade efficiency |
| Leverage | cache_read / input |
Context reuse |
| Velocity | output / input |
Output amplification |
| SNR | output / (input + output) |
Signal cleanliness |
| 10xDEV | log10(cache_read / input) |
Dev leverage |
Null semantics
- When a denominator is zero, the metric is
None(not 0 or Infinity) - When
cache_readisNone, Yield, Leverage, and 10xDEV areNone - When
cache_writeisNone, 10xDEV isNone
