Show HN: A Swift Payment message validator built from Swift Standard rules

Operating in show hn launch, A Swift Payment message validator built from Swift Standard rules operates.

Profile

I built CBPR Star to allow engineers & testers to validate and edit SWIFT payment system messages for XSD and Business / Usage rules. The interesting bit is the Business / Usage rules, as they are provided in a mixture of prose and pseudo code by SWIFT. I used coding agents (Claude code mainly) to go from text to python, still a fairly labour intensive task - but considerably quicker than manually doing the same. SWIFT's own MyStandards is similar but less comprehensive and a lot more clunky. There's also an MCP, not fully released that.

The company sits in the show hn launch segment, where it competes on its core product or service.

It is recorded at the Show HN launch stage.
