Zod

Developer Tools

TypeScript-first schema validation library with static type inference. Define schemas (z.string(), z.object(), z.array()) and Zod derives both runtime validation and TypeScript types from them — single source of truth. Used extensively for form validation, API input parsing, environment variable validation, and OpenAI function calling schemas in TypeScript agents.

ArchUnit

Developer Tools

Java architecture testing library that validates architectural constraints as unit tests. ArchUnit imports Java bytecode and applies rule checks: no cycles between packages, layered architecture rules (controllers don't import repositories), naming conventions, annotation requirements, dependency restrictions, and custom rules. Rules run as standard JUnit 5 or JUnit 4 tests — architecture violations appear as test failures with detailed violation messages. Catches architecture drift before it becomes technical debt. Rules expressed in fluent DSL: classes().that().resideInPackage('..controller..').should().onlyDependOnClassesThat()...
