Playwright Cli

playwright-cli

playwright-cli is a token-efficient shell interface to Playwright. It keeps browser state across commands, exposes page snapshots with stable element refs such as e15, and prints the Playwright code it ran so the interaction can be converted into tests.

Core Workflow

playwright-cli open https://example.com
playwright-cli snapshot
playwright-cli click e15
playwright-cli fill e5 "user@example.com"
playwright-cli press Enter
playwright-cli close

Use refs from the latest snapshot by default. Re-run snapshot after navigation, major DOM changes, or a failed ref action. Use CSS selectors or Playwright locators only when refs are unavailable or unstable.

Operating Rules

• Discover exact syntax with playwright-cli --help and playwright-cli --help; the CLI changes quickly.
• Use --raw when piping values into other tools. Use --json only if the installed CLI advertises it.
• Use named sessions with -s= for concurrent or long-lived work.
• Use open --persistent only when disk-persisted cookies/storage are needed.
• Prefer attach --cdp=chrome, attach --cdp=msedge, or attach --cdp=http://127.0.0.1:9222 when the task needs an existing browser/session.
• Close sessions when finished. Reserve close-all and kill-all for cleanup of stale sessions.

Common Tasks

playwright-cli open https://example.com --browser=chrome
playwright-cli snapshot --depth=4
playwright-cli screenshot --filename=page.png
playwright-cli console warning
playwright-cli network --filter="/api/.*" --request-headers
playwright-cli run-code "async page => await page.context().grantPermissions(['geolocation'])"
playwright-cli tracing-start
playwright-cli tracing-stop

Playwright Test Debugging

When a Playwright test fails, prefer the CLI debug workflow:

PLAYWRIGHT_HTML_OPEN=never npx playwright test --debug=cli
# wait for "Debugging Instructions", then attach to the printed session
playwright-cli attach tw-abcdef

Keep the test process running while inspecting the paused page. Use snapshots, console/network inspection, and generated Playwright code to identify the fix.
