JetBrains' Koog 1.0 locks stable API for agent tools, workflows, and observability across Kotlin/Java, with one-year breaking-change guarantee and OpenTelemetry support.
July 7, 2026
Summary
Reduces risk for production agent deployments on JVM—stable core modules eliminate migration churn, while decoupled HTTP transport and improved persistence let you integrate agents into existing infrastructure without framework rewrites.

Implementation verdict
Replaces internal agent scaffolding if you're building on Kotlin/JVM. Requires learning Koog's tool/workflow patterns. Worth adopting now if you need multiplatform observability or plan long-running agents; skip if your stack is Python-first.
