Switch JDK, Kotlin, Gradle, Maven, or any SDKMAN-managed candidate when the user or runtime explicitly demands a different version. Use when the user says "switch to Java 17", "run with JDK 21", "use Gradle 8.x", asks about JAVA_HOME, a build fails with UnsupportedClassVersionError or "class file has wrong version", or the repo contains a `.sdkmanrc`. Operates on machines configured with SDKMAN (`$SDKMAN_DIR`, default `~/.sdkman`).
Browser automation toolkit using Selenium WebDriver 4+ with Java 21+ and JUnit 5. Use when asked to create, debug, or run Selenium tests, implement Page Object Model, handle explicit waits with WebDriverWait, capture screenshots, verify UI elements with AssertJ assertions, test forms, validate user flows, or set up Maven test projects. Supports Chrome, Firefox, and Edge browsers.
Generate MSBuild binary logs (binlogs) for build diagnostics and analysis. Only activate in MSBuild/.NET build context. USE FOR: adding /bl:{} to any dotnet build, test, pack, publish, or restore command to capture a full build execution trace, prerequisite for binlog-failure-analysis and build-perf-diagnostics skills, enabling post-build investigation of errors or performance. Requires MSBuild 17.8+ / .NET 8 SDK+ for {} placeholder; PowerShell needs -bl:{{}}. DO NOT USE FOR: non-MSBuild build systems (npm, Maven, CMake), analyzing an existing binlog (use binlog-failure-analysis instead). INVOKES: shell commands (dotnet build /bl:{}).
Catalog of MSBuild anti-patterns with detection rules and fix recipes. Only activate in MSBuild/.NET build context. Use when reviewing, auditing, or cleaning up .csproj, .vbproj, .fsproj, .props, .targets, or .proj files. Each anti-pattern has a symptom, explanation, and concrete BAD→GOOD transformation. DO NOT use for non-MSBuild build systems (npm, Maven, CMake, etc.).
Scan project dependencies for CVEs, outdated packages, and license compliance across npm, pip, cargo, go, maven, and other ecosystems. Use for vulnerability scanning, SBOM generation, supply chain analysis, and automated dependency updates.
Run Google's OSV-Scanner for Software Composition Analysis. Scans lockfiles and SBOMs across all major ecosystems (npm, PyPI, Maven, Go, Cargo, NuGet, RubyGems) for known vulnerabilities.
Manage Harness Artifact Registry (AR) via MCP. Configure private registries for Docker, Helm, Maven, npm, and PyPI artifacts, set up upstream proxies for caching public images, configure RBAC and cross-region replication, and define security scanning policies with CVE thresholds and license compliance checks. Use when asked to set up an artifact registry, configure Docker or Helm repositories, manage artifact security scanning, or set up replication. Do NOT use for creating connectors to external registries (use create-connector instead). Trigger phrases: artifact registry, docker registry, helm repository, artifact security, image scanning, private registry, artifact replication, CVE threshold, license compliance, SBOM.
Professional network graph analyst identifying Gladwellian superconnectors, mavens, and influence brokers using betweenness centrality, structural holes theory, and multi-source network reconstruction. Activate on 'superconnectors', 'network analysis', 'who knows who', 'professional network', 'influence mapping', 'betweenness centrality'. NOT for surveillance, discrimination, stalking, privacy violation, or speculation without data.
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".
Use when you need to set up, review, or improve Java integration tests — including generating a BaseIntegrationTest.java with WireMock for HTTP stubs, detecting HTTP client infrastructure from import signals, injecting service coordinates dynamically via System.setProperty(), creating WireMock JSON mapping files with bodyFileName, isolating stubs per test method, verifying HTTP interactions, or eliminating anti-patterns such as Mockito-mocked HTTP clients or globally registered WireMock stubs.
