Generic E2E patterns with Playwright—state setup, seeds, test IDs, auth, environment, and Sail integration
Use when implementing features or fixes - test-driven development with RED-GREEN-REFACTOR cycle and full code coverage requirement
How to effectively test the application, always use when writing tests
Framework for defining, monitoring, and enforcing guardrail metrics across experiments.
Design and implement visual regression testing for UI changes. Defines screenshot coverage, rendering stabilization, baseline management, and CI integration (e.g., Playwright screenshots, Percy/Chromatic). Use when UI/styling/layout changes need protection against regressions, or when adding screenshot-based tests to a web/WASM/desktop UI.
Use when running tests to validate implementations, collecting test evidence, or debugging failures. Load in TEST state. Covers unit tests (pytest/jest), API tests (curl), browser tests (Claude-in-Chrome), database verification. All results are code-verified, not LLM-judged.
Audits feature completeness by scanning codebases and comparing against PRD requirements. Identifies gaps between backend implementation and user-facing accessibility. Generates remediation tasks and integrates with prd-analyzer output. Supports multiple frameworks including Next.js, React Router, TanStack, React Native, Expo, and more.
AI-powered E2E testing for any app. Test 8 platforms with natural language — no test code needed.
Self-contained test automation — invoke directly, do not decompose. End-to-end integration test that assembles a fixture, deploys Connect + Cloudflare, and presents a live URL for browser verification.
Test coverage, code quality, defect metrics, and QA KPIs
Systematic debugging playbook for application errors and incidents: crashes, regressions, intermittent failures, production-only bugs, performance issues, stack traces, log/trace analysis, profiling, and distributed systems root cause analysis.
Testing frameworks for web, mobile, API, and unit testing
