subagent-driven-development is an AI agent execution pattern that uses a fresh subagent for each independent task within a session. It is defined by a mandatory two-stage review process conducted after each task: a specification compliance review followed by a code quality review.
systematic-debugging is an AI Agent skill that enforces a strict debugging process. It prohibits proposing fixes until a root cause investigation is complete, ensuring that solutions address underlying issues rather than just symptoms.
Test-driven development is a software development process that relies on the repetitive cycle of writing tests before writing implementation code.

springboot-tdd is an AI agent skill that provides a structured test-driven development workflow for Spring Boot applications. It guides developers through writing tests first with JUnit 5 and Mockito, implementing minimal code, and enforcing code coverage with JaCoCo.
swift-concurrency-6-2 is a concurrency model in Swift 6.2 that runs code single-threaded by default and introduces concurrency explicitly using @concurrent for background offloading and isolated conformances for main actor types.
swift-protocol-di-testing is a protocol-based dependency injection approach for creating testable Swift code. It abstracts external dependencies like file systems, network calls, and external APIs behind focused protocols using Swift Testing, enabling deterministic tests without actual I/O operations.
