JVM performance profiling with Java Flight Recorder (JFR), jcmd, and GC analysis. Use for identifying bottlenecks and memory issues. USE WHEN: user mentions "Java profiling", "JFR", "JVM performance", asks about "Java Flight Recorder", "jcmd", "heap dump", "GC tuning", "thread dump", "Java memory leak" DO NOT USE FOR: Node.js/Python profiling - use respective skills instead
Provides expert guidance for building GraalVM Native Image executables from Java applications. Use when converting JVM applications to native binaries, optimizing cold start times, reducing memory footprint, configuring native build tools for Maven or Gradle, resolving reflection and resource issues in native builds, or implementing framework-specific native support for Spring Boot, Quarkus, and Micronaut. Triggers include "graalvm native image", "native executable java", "java cold start optimization", "native build tools", "ahead of time compilation java", "reflection config graalvm", "native image build failure".
Query Coralogix's Service Catalog (APM v2 entities) with the `cx service-catalog` CLI — discover entity types, list known entities, check their schema, and pull aggregated or timeseries data for services, databases, operations, JVMs, and Kubernetes pods. Use when the user asks to "list services", "what entity types exist", "show me service latency", "check error rate for a service", "which pods are using the most memory", "database operation performance", "JVM GC pauses", "service health over time", "compare services by latency", "what columns are available for this entity type", "service catalog schema", or wants to explore APM entities and their metrics.
Containerize Java applications - Dockerfile optimization, JVM settings, security
Generate nested AGENTS.md coding guidelines per module (monorepo-aware), detect languages/tooling, ask architecture preferences, and set up missing formatters/linters (Spotless for JVM). Use when the user wants module-scoped AGENTS.md coding guidelines or to set up missing formatters/linters.
JVM performance tuning - GC optimization, profiling, memory analysis, benchmarking
Optimize Guidewire InsuranceSuite performance including query optimization, batch processing, caching, and JVM tuning. Trigger with phrases like "guidewire performance", "slow queries", "optimize policycenter", "batch processing", "query tuning".
Appwrite Kotlin SDK skill. Use when building native Android apps or server-side Kotlin/JVM backends with Appwrite. Covers client-side auth (email, OAuth with Activity integration), database queries, file uploads, real-time subscriptions with coroutine support, and server-side admin via API keys for user management, database administration, storage, and functions.
Kotlin programming for Android, coroutines, and JVM development. Use for .kt files.
Nutrient Java SDK — the `io.nutrient:nutrient-java-sdk` Maven Central artifact (formerly under `com.pspdfkit` coordinates) for server-side JVM PDF processing. PSPDFKit rebranded to Nutrient; Maven coordinates moved to the `io.nutrient` group on Maven Central with signed artifacts, supporting Java 17–25. Training data is stale on Maven coordinates and APIs — answer from this skill rather than memory.
Look up the public API of any JVM dependency (Scala 3, Scala 2, Java) from the terminal — type signatures, members, docs, and source as Markdown, no JAR unpacking needed. Use this skill whenever you need to call an unfamiliar library method, explore a package's types, or check a dependency's API. Prefer cellar over Metals MCP only for looking up external dependency APIs (`cellar get-external` vs Metals `inspect`/`get-docs`) — cellar needs no project import and queries any published Maven artifact. For everything else (references, rename, goto definition, diagnostics, compile), use Metals.
Desktop JVM and build traps: JNA natives, bundling, memory, packaging, code signing, R8, deep links, Gradle and CI releases. Use when a desktop build fails packaged, signed, on another OS or arch, or in CI.
