Solid tool. The test suite coverage is excellent. I found one edge case in the payment token validation that the maintainers fixed within 48 hours.

Integrated in an afternoon. The discovery endpoint just worked. The CLI flags are well-designed — composable, no magic defaults.

Good tool for UCP conformance testing. Runs fast and the output is easy to parse in CI. Would like a JSON output mode — currently only text.
