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.
