Use the host-side `agent-browser` CLI for local browser smoke tests, screenshots, snapshots, and simple UI validation against forwarded localhost URLs.
# agent-browser Use this skill when verification needs a real browser after the app is booted from the sandbox. This project uses `agent-browser` on the host, not inside Shuru. The usual flow is: 1. Start the app with sandboxed bash. 2. Expose it through a forwarded localhost port. 3. Use `agent-browser` against that localhost URL. ## Requirements - The `agent-browser` CLI must be installed and available on `PATH`. - Prefer `http://127.0.0.1:<port>` or another explicit localhost URL. - Use a named browser session when there is any chance of concurrent runs. ## Core flow ```bash agent-browser --session verify open http://127.0.0.1:3000 agent-browser --session verify wait --load networkidle agent-browser --session verify snapshot -i ``` After any click or navigation, re-snapshot before using old refs again. ## Common commands ```bash # Open and wait for readiness agent-browser --session verify open <url> agent-browser --session verify wait --load networkidle # Inspect the page agent-browser --session verify snapshot -i agent-browser --session verify get title agent-browser --session verify get url # Interact with elements from snapshot refs agent-browser --session verify click @e1 agent-browser --session verify fill @e2 "text" agent-browser --session verify press Enter # Record the smoke test as video agent-browser record start .grok/verify-artifacts/verify-smoke.webm # Capture screenshot proof (use --screenshot-dir, not a positional path) mkdir -p .grok/verify-artifacts agent-browser --screenshot-dir .grok/verify-artifacts screenshot agent-browser --screenshot-dir .grok/verify-artifacts screenshot --full # Stop recording and clean up agent-browser record stop agent-browser close ``` ## Guidance - Keep browser checks narrow in phase 1: page load, one or two critical controls, and optional screenshot evidence. - Save screenshots to stable workspace-relative paths under `.grok/verify-artifacts/` so verify can report them back to the user. - Prefer `wait --load networkidle` after `open`. - If the page is dynamic, use `snapshot -i` again after each meaningful DOM change. - If the target URL is ambiguous because multiple forwarded ports exist, stop and report the ambiguity instead of guessing. - If `agent-browser` is unavailable, fall back to bash-only verification and say so clearly.
