Toolkit for interacting with and testing local web applications using Playwright. Supports verifying frontend functionality, debugging UI behavior, capturing browser screenshots, and viewing browser logs.

Write comprehensive unit and integration tests with proper mocking and coverage

Perform cohort analysis on user data — retention curves, feature adoption, and engagement trends

Analyze A/B test results — statistical significance, sample size validation, and ship/extend/stop recommendations

Turn documented intent into a test-coverage map — inventory the tests that exist today, derive use-case cases from the system docs, separate existing coverage from proposed tests and unverified gaps, mark each unit / guarded-live / manual, and recommend a green-before-merge CI gate

Generate realistic dummy datasets for testing — CSV, JSON, SQL inserts, or Python scripts

Static performance audit of AI-built code — find N+1 queries and request waterfalls, over-fetching, missing indexes, and caching opportunities, ranked by effort and impact

Turn a vibe-coded repo into a reviewer-ready shipping packet — document the app, wire agent context, run security and performance audits, map test coverage, and compile the results

Generate comprehensive test scenarios from user stories or feature specs — happy paths, edge cases, and error handling
