Integration and E2E test design principles, ROI calculation, test skeleton specification, and review criteria. Use when designing integration tests, E2E tests, or reviewing test quality.

Language-agnostic testing principles including TDD, test quality, coverage standards, and test design patterns. Use when writing tests, designing test strategies, or reviewing test quality.

Test implementation patterns and conventions. Use when implementing unit tests, integration tests, or E2E tests, including RTL+Vitest+MSW component testing and Playwright E2E testing.

Test implementation patterns and conventions. Use when implementing unit tests, integration tests, or E2E tests, including RTL+Vitest+MSW component testing and Playwright E2E testing.

Executes implementation tasks through Todo, In Progress, To Review. Use when task needs coding with KISS/YAGNI. Not for test tasks.

Detects tests proving platform behavior instead of local product behavior. Use when auditing product-behavior focus.

Executes optimization hypotheses with keep/discard testing loop. Use when applying validated performance improvements.

Performs manual testing of Story AC via executable bash scripts in tests/manual/. Use when Story implementation needs hands-on AC verification.

Audits whether test results can be trusted: flakiness, isolation, real external dependencies, time/random/order dependency, and shared state. Use when auditing test trustworthiness.

Orchestrates test planning pipeline: research, manual testing, automated test planning. Use when Story needs comprehensive test coverage planning.

Creates complete project documentation system (project docs, reference, tasks, tests). Use when bootstrapping docs from scratch or regenerating all.

Reviews task implementation for quality, code standards, and test coverage. Use when task is in To Review. Sets task Done or To Rework.
