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.
Move quality earlier in the development lifecycle. Covers dev/QA pairing patterns, Three Amigos sessions, TDD facilitation (Red-Green-Refactor), PR review checklists for testability, and Definition of Done with quality gates. Includes shift-left maturity model for team assessment. Use when: "shift left," "TDD," "dev-QA pairing," "definition of done," "testability," "quality culture," "QA in sprint planning." Not for: writing the unit tests themselves — use unit-testing; automated PR test-quality review at scale — use ai-qa-review; multi-quarter QA direction or roadmap — use test-strategy. Related: unit-testing, ai-qa-review, test-strategy.
Reviews feature specifications for completeness, testability, and implementation readiness. Validates acceptance criteria, edge cases, and technical constraints. Use when reviewing feature specs before implementation or during sprint planning.
Use when writing unit tests, adopting Swift Testing framework, making tests run faster without simulator, architecting code for testability, testing async code reliably, or migrating from XCTest - covers @Test/@Suite macros,
Critical Akka.NET best practices including EventStream vs DistributedPubSub, supervision strategies, error handling, Props vs DependencyResolver, work distribution patterns, and cluster/local mode abstractions for testability.
Implement VIP (View-Interactor-Presenter) Clean Architecture for iOS apps requiring maximum testability, unidirectional data flow, and protocol-based boundaries. Use when refactoring complex features or building enterprise apps with strict separation of concerns.
Expert guidance on The Composable Architecture (TCA) for Swift, focusing on ReducerProtocol, macros, and testability.
Generate a requirements-quality checklist for an OpenSpec change and run it against the proposal/design/tasks/delta — validating completeness, clarity, consistency, and testability BEFORE you approve the spec. Modeled on GitHub Spec-Kit's /checklist. Use when reviewing a spec at the human approval gate, or before launching implementation, to catch under-specified requirements early.
Provides implementation patterns for Clean Architecture, Hexagonal Architecture (Ports & Adapters), and Domain-Driven Design in Java 21+ Spring Boot 3.5+ applications. Use when structuring layered architectures, separating domain logic from frameworks, implementing ports and adapters, creating entities/value objects/aggregates, or refactoring monolithic codebases for testability and maintainability.
Conduct context-driven code reviews focusing on quality, testability, and maintainability. Use when reviewing code, providing feedback, or establishing review practices.
Safely refactor code to improve structure, clarity, or testability without changing intended behavior. Use when the user says "refactor it", asks to clean up a module, extract helpers, reduce duplication, or prepare code for a feature — not for product behavior changes (use fix-it) or pure test adds (use test-it). Prefer small steps with tests green between steps.
Builds and stress-tests implementation plans in two modes. Create mode scans code and docs, asks one question at a time with a recommended answer, runs a blindspot pass when the user is new to the area, then writes a plan file. Review mode scores completeness, feasibility, scope, testability, risk, and assumptions, verifies checkable claims, and writes resolutions back until every dimension reaches 5/5. Use when asked to "create a plan", "plan this feature", "I want to build X", "grill me", "think this through", "blindspot pass", "unknown unknowns", "this is new to me", "review my plan", "rubber duck this", "stress test this plan", "is this plan ready", "get this plan to 5/5", "what am I missing", "verify this claim", "prove this plan", "fact-check this plan", "split this into tickets", "break this down into slices", "this is too big for one plan", or when the user explicitly wants a plan artifact before implementation. For code review use pr-reviewer; for architecture briefs use codebase-architecture.
