Browser Automation Agent Skill

Browser Automation

What I Do

• Attach OpenCode browser tools to the iPolloWork Electron app during local development.
• Drive the app UI through Electron's Chrome DevTools Protocol endpoint.
• Send a task/session from the composer and confirm the response in the UI.

Local Dev Setup

pnpm dev enables Electron CDP by default:

IPOLLOWORK_ELECTRON_REMOTE_DEBUG_PORT=${IPOLLOWORK_ELECTRON_REMOTE_DEBUG_PORT:-9823}

The default browser URL for OpenCode browser tools is:

http://127.0.0.1:9823

The app UI normally loads at:

http://localhost:5173/

To use a different CDP port, launch with an override:

IPOLLOWORK_ELECTRON_REMOTE_DEBUG_PORT=9830 pnpm dev

To disable Electron CDP for a run:

IPOLLOWORK_ELECTRON_REMOTE_DEBUG_PORT=0 pnpm dev

Background Launch

Use a detached launch when the user wants the app running in the background:

nohup pnpm dev > /var/folders/d9/xqhkvsp94rg0n0n523snqztm0000gn/T/opencode/ipollowork-dev.log 2>&1 &

Then wait for the CDP port:

lsof -nP -iTCP:9823 -sTCP:LISTEN

Browser Tool Flow

• List targets with browser_list using browser_url: "http://127.0.0.1:9823".
• Select the iPolloWork target ID.
• Read state with browser_eval or browser_snapshot.
• Fill the Lexical composer by targeting [contenteditable="true"][data-lexical-editor="true"].
• Click the Run task button.
• Confirm the session response by checking document.body.innerText or the current URL.

Send A Session

Use this browser_eval pattern after selecting the iPolloWork target:

(() => {
  const editor = document.querySelector('[contenteditable="true"][data-lexical-editor="true"]');
  if (!editor) return { ok: false, reason: 'editor not found' };

  editor.focus();
  const data = new DataTransfer();
  data.setData('text/plain', 'Say hello from the Electron browser test.');
  editor.dispatchEvent(new ClipboardEvent('paste', {
    bubbles: true,
    cancelable: true,
    clipboardData: data,
  }));

  const run = Array.from(document.querySelectorAll('button'))
    .find((button) => button.innerText.trim() === 'Run task');
  if (!run) return { ok: false, reason: 'Run task not found', inserted };
  if (run.disabled) return { ok: false, reason: 'Run task disabled', inserted, text: editor.innerText };

  run.click();
  return { ok: true, inserted: true, text: editor.innerText };
})()

Notes

• Electron CDP is used for development test tooling. User browser tasks should use the built-in iPolloWork Browser target.
• A successful local attach should show an iPolloWork target at http://127.0.0.1:9823.
• The known-good smoke prompt is Say hello from the Electron browser test. and the expected response is Hello from the Electron browser test.
