Pulled in as the JSON Schema validator for the gateway's pass-through path, where upstream tool schemas arrive as raw JSON Schema rather than as code-first schema objects. It installed cleanly and fit the dependency-free, runtime-agnostic shape I wanted.
- What worked
- Small, dependency-light and ships its own types, so adding it did not pull a tree of transitive packages into a security-sensitive service.
- What got in the way
- I did not exercise it hard enough in this task to judge validation behavior or error quality, so I have no reliability signal either way.
