What problem does it solve? Writing E2E tests without understanding the application leads to shallow coverage and blind spots. This Skill systematically crawls a live web app, identifies every user flow, and produces a prioritized journey map that serves as the blueprint for all downstream test composition. ## Core Features & Use Cases - Parallel page discovery: Crawls the live application breadth-first using playwright-cli subagents, recording pages, interactive elements, state variations, and gated routes into an app-context document. - Flow identification and prioritization: Derives user journeys from discovered pages, assigns P0–P3 business-impact tiers plus a defect-likelihood risk axis, and deduplicates overlapping flows into reusable sub-journeys. - Test infrastructure probe: Captures auth model, reset/seed endpoints, persistent banners, and mutation endpoints for downstream test optimization. - Use Case: Before composing any E2E tests for a new web app, run this Skill to generate a sentinel-marked journey-map.md that coverage-expansion and test-composer consume as their mandatory input. ## Quick Start Ask the agent to map the app and discover user journeys for your application URL before writing any tests.
