Create a new business use case (Request + UseCase + Test) following TDD workflow. Use when user asks to implement new business logic, domain operations, or create commands/queries. Always follow Red-Green-Refactor cycle.

Comprehensive backend development guide for Node.js/Express/TypeScript microservices. Use when creating routes, controllers, services, repositories, middleware, or working with Express APIs, Prisma database access, Sentry error tracking, Zod validation, unifiedConfig, dependency injection, or async patterns. Covers layered architecture (routes → controllers → services → repositories), BaseController pattern, error handling, performance monitoring, testing strategies, and migration from legacy patterns.

Implement tasks from plans with test-first approach, user-story-centric execution, and AC verification. Use proactively when executing implementation plans. Enforces quality gates, MVP-first delivery, and Article VII story-by-story implementation.

Implementation Agent: Full TDD workflow in a single context window. Writes tests, implements code, and iterates until all tests pass.

Scaffolds new frontend pages/features with TDD approach, following established UI patterns from BuildProject/Baker pages. Generates page component, test file, updates routing, and maintains 90%+ test coverage before implementing production code. Use this when creating new pages or features in the Bucket app.

Automates TEST_CATALOG updates after test execution. Records test metrics, pass/fail status, coverage data, and execution time. Maintains single source of truth for all test files and their health status.

Debug SystemVerilog testbench failures in the SVC project. Use when a testbench fails (make <module>_tb), to analyze CHECK_* assertion failures, watchdog timeouts, or unexpected signal values. Provides systematic debugging workflow using VCD waveforms and failure output analysis.

This skill should be used when the user asks to "add unit tests", "write tests", "set up Vitest", "create a utility function", "add test coverage", or mentions TDD, test-driven development, or testing utilities. Provides guidance for unit testing with Vitest in TypeScript/Next.js projects using TDD approach.

Validate requirements quality - unique keys, acceptance criteria, testability, clarity. Sensor detecting requirement quality issues. Use before moving to Design stage or as quality gate.
