Arazzo Criterion

Apache-2.0

A parser, validator and evaluator for the Arazzo Criterion Object — the success-criteria conditions in `simple`, `regex`, `jsonpath` and `xpath` types that decide whether a step succeeded. Isolates the one piece of Arazzo where two runners are most likely to disagree, which is exactly what a conformance suite would test.

Where it applies

Jobs this tool actually does, and the surface each one is exercised on.

Evaluate a step's success criteria against a captured response the same way across tools.
coding-agentci-pipeline

The maintainer has written about the one condition type no tool can evaluate safely; read that before trusting regex criteria.
