# Playwright CLI Validation Use Playwright CLI for low-level browser control and deterministic UI evidence. Required rules: - Use named sessions with `PLAYWRIGHT_CLI_SESSION` or `playwright-cli -s=<session>`. - Store screenshots, snapshots, traces, and temporary browser evidence under `browser/`. - Capture before/after or state-specific screenshots when visual behavior changed. - Use `playwright-cli show --annotate` for human-visible inspection in headed or cmux workflows when useful. - Mark unavailable runtime as `NOT_PROVEN`; do not invent browser evidence. Common commands: ```bash playwright-cli --help playwright-cli -s="${RY_PROJECT_SLUG:-rldyour}" open "$URL" playwright-cli -s="${RY_PROJECT_SLUG:-rldyour}" snapshot --filename browser/snapshot.yaml playwright-cli -s="${RY_PROJECT_SLUG:-rldyour}" screenshot --filename browser/ui.png playwright-cli -s="${RY_PROJECT_SLUG:-rldyour}" tracing-start playwright-cli -s="${RY_PROJECT_SLUG:-rldyour}" tracing-stop ```
