Strategic guidance for choosing and implementing testing approaches across the test pyramid. Use when building comprehensive test suites that balance unit, integration, E2E, and contract testing for optimal speed and confidence. Covers multi-language patterns (TypeScript, Python, Go, Rust) and modern best practices including property-based testing, test data management, and CI/CD integration.
Comprehensive testing specialization covering test strategy, automation, TDD methodology, test writing, and web app testing. Use when setting up test infrastructure, writing tests, implementing TDD workflows, analyzing coverage, integrating tests into CI/CD, or testing web applications with Playwright. Framework-agnostic approach with framework-specific guidance via reference files.
Comprehensive thoroughness framework. Auto-invoked when planning features, implementing code, fixing bugs, writing tests, analyzing existing code, auditing features, reviewing architecture, or investigating issues. Forces systematic consideration of all edge cases, failure modes, error scenarios, security implications, state transitions, and hidden assumptions so nothing gets missed. Do NOT invoke for trivial changes like typos, renames, single-line fixes, adding imports, or updating config values.
Detailed development workflow patterns, checklists, and standards. Auto-loads for complex tasks, planning, debugging, testing, or when explicit patterns are needed. Contains session protocols, git conventions, security checklists, testing strategy, and communication standards.
Use when an agent is asked to define, review, or write acceptance criteria for a request or plan. Derives acceptance criteria from the current request context, confirms them with the user, and writes them into the plan file or a standalone acceptance_criteria.md file.
2. Create Feature Design Document
Generates technical implementation plans and architectural strategies that enforce the Project Constitution. Use when designing new features, starting implementation tasks, refactoring code, or ensuring compliance with critical standards like Testability-First Architecture, security mandates, testing strategies, and error handling.
Core code quality principles for writing maintainable code. Use when reviewing code for design violations, assessing code quality, or applying architectural patterns like composition, immutability, and fail-fast.
Complete workflow for developing new features from design to deployment. Use when starting a new feature, adding functionality, or building something new.
Implement a full-stack feature following an approved plan. Builds database layer, backend API, frontend components, and tests. Use after plan-feature has produced an approved implementation plan, or when you have a clear set of tasks to implement across the stack.
Architecture principles, module boundaries, folder structure, and project type profiles
Use when choosing a testing strategy, right-sizing test coverage, or understanding test categories. Covers the Test Trophy model, test type tradeoffs, and guidance on balancing static analysis, unit, integration, and end-to-end tests. USE FOR: testing strategy, Test Trophy, test type selection, right-sizing test coverage, balancing test categories, choosing testing tools, test automation architecture DO NOT USE FOR: specific test category implementation (use static-analysis, unit-testing, integration-testing, e2e-testing, etc.), BDD specification authoring (use specs/documentation/gherkin)
