What problem does it solve? Manually verifying that a branch's changes actually work in a running app is slow and error-prone: you must start the dev stack, log in, click through affected pages, and remember to clean up. This Skill automates that entire loop with Playwright driven by your real browser session. ## Core Features & Use Cases - Isolated dev stack startup: Launches your app on isolated ports so multiple worktrees can run in parallel against a shared database and storage. - Real session authentication: Extracts the session cookie from the user's actual browser (Arc, Brave, Chrome, Edge) and injects it into Playwright, so tests run as a logged-in user. - Diff-aware testing: Analyzes the branch's git diff to map changed files to the UI surfaces that exercise them, then verifies happy paths and edge cases with screenshots. - Use Case: After finishing a feature branch, ask the agent to "e2e verify this branch" — it boots the stack, signs in, exercises the changed flows, persists key assertions into your e2e spec suite, and tears everything down. ## Quick Start Ask the agent to e2e verify the current branch, optionally passing an app URL or port if your stack is already running.
