⚡ Mokksy 0.10 is out! This release focuses on more realistic integration testing: • YAML-based stub loading • multipart & form body matching • improved verification APIs Built for testing modern HTTP & streaming APIs on the JVM. github.com/mokksy/mokks... mokksy.dev

Direct prompt injection is only the first layer. Higher-order attacks embed malicious intent in the code an agent dependencies it adds, and the trust chains it inherits — executing later in CI, production, or downstream agents. kpavlov.me/blog/agent-h... #ai #security #AttackVector

Mokksy just got a facelift✨💄 The go-to toolkit for mocking HTTP APIs with SSE streaming and LLMs now has a brand new design. Explore the update at mokksy.dev #AI #DeveloperTools #OpenSource #Kotlin #Mokksy #SoftwareTesting #ServiceVirtualization

Kotlin MCP SDK 0.11.0 is out! Highlights: - Elicitation support - Upgraded to Kotlin 2.3, Ktor 3.3, serialization - Configurable max request payload size + automatic JSON setup - Full conformance test suite is finally green github.com/modelcontext... #Kotlin #MCP #AI #SDK #APIs #DeveloperTools

#Javable: generate Java-friendly wrappers for #Kotlin with #KSP Annotate your Kotlin class and functions, and Kotlin Symbol Processor generate #CompletableFuture-based async adapters, blocking wrappers, and Java Stream-based #Flow collectors — with correct #CoroutineScope lifecycle management.

kotlinx-schema v0.4 is out — with first-class sealed class support! Excited to announce the release of kotlinx-schema 0.4.0, bringing one of the most requested features: polymorphic type support for JSON Schema and LLM function calling schemas. github.com/kotlin/kotli...

Kotlin’s flexibility — multiple classes and extension functions in one file — is a feature, not a bug. But without team conventions and static analysis, files can quietly grow past 1,000 lines. kpavlov.me/blog/kotlin-...

Spring Modulith is very valuable tool to avoid dependency cycles between modules in enterprise applications. Must-have tool for every serious project.

Unit tests won’t catch what breaks in production. If your service talks to external HTTP systems — mocking isn’t enough. You miss real config, timeouts, retries, and streaming behaviour. #Mokksy is a #Kotlin mock server with real HTTP & SSE support for black-box integration tests.
