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

Higher-Order Attacks on AI Code Agents

Beyond direct prompt injection lies a more dangerous class of attacks: manipulating the agent into writing malicious code that executes later in CI or production. This article examines second-order co...

#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.

Javable: generate Java-friendly wrappers for Kotlin with KSP

When building a Kotlin library, the JVM interop story is often painful: suspend functions expose a raw Continuation parameter in Java, Flow has no Java equivalent, and data classes with many parameter...

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-...

Large files in Kotlin: causes, trade-offs, and practical remedies

Kotlin's permissive file organization model enables expressive, cohesive code — but it also explains why large files are commonplace even in mature Kotlin libraries. This article examines the cultural...

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.

Mokksy: A Mock Server That Actually Streams — and Why Your AI App Needs Integration Tests

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.
