Every time you rename a Kotlin function parameter, the hand-written JSON schema your LLM reads is wrong — and it fails silently. kotlinx-schema derives the schema from your Kotlin types directly, via three strategies that cover runtime and compile-time generation across all Kotlin Multiplatform targets.

Kotlin encourages grouping related code in a single file, which is useful — until files grow past 1,000 lines. This article explores why that happens, how it affects LLM-based tooling, and what teams can do about it.

Why unit tests alone won’t save your LLM application in production, and how Mokksy — a Kotlin mock server with true SSE and streaming support — fills the gap that WireMock leaves wide open.

Open-source libraries may power critical systems where failures have severe consequences. AI tools now eliminate the excuse of insufficient testing time, but engineers must own the final quality decision.

Generate JSON Schema for Kotlin Multiplatform models and API functions, so your schema stays in sync with your code.
