Gemini Worker

Send a prompt to Gemini via browser and return the response.

Environment

• Browser: Chrome on localhost:9222 (managed by local-browser-tools)
• Login: Not required — Gemini guest mode is confirmed working
• Tools: browser-start.js, browser-nav.js, browser-eval.js, browser-screenshot.js

---

Input

prompt: string        # The text to send to Gemini
task_type: string     # qa | summary | translation | rewrite | extraction | comparison | brainstorming | analysis

---

Output

Always output this JSON block first:

{
  "site": "gemini",
  "task_type": "<task_type>",
  "status": "success | partial | error",
  "answer": "<extracted response text>",
  "retry_count": 0,
  "elapsed_ms": 0,
  "error_reason": null
}

Then follow with a short human-readable summary (2–3 sentences max).

Workflow

Step 1 — Start browser

node ~/.pi/agent/skills/local-browser-tools/browser-start.js

Expected: ✓ Chrome already running on :9222 or ✓ Chrome started on :9222

If fails: return error status, stop.

---

Step 2 — Navigate to Gemini

node ~/.pi/agent/skills/local-browser-tools/browser-nav.js https://gemini.google.com/app

After navigation, take a screenshot and verify:

• Input box is visible
• Page is NOT a login wall (a "Sign in" button in the top-right corner is normal and acceptable — guest mode works)

If a full-page login form appears with no input box: return error status, stop.

---

Step 3 — Locate input box

Try selectors in this order until one works:

1. [aria-label="Enter a prompt for Gemini"]
2. [contenteditable="true"][role="textbox"]
3. div.ql-editor

Use browser-eval.js to check:

!!document.querySelector('[aria-label="Enter a prompt for Gemini"]')

If no selector works after 3 attempts: trigger retry.

---

Step 4 — Insert prompt

(function() {
  const input = document.querySelector('[aria-label="Enter a prompt for Gemini"]')
    || document.querySelector('[contenteditable="true"][role="textbox"]')
    || document.querySelector('div.ql-editor');
  if (!input) return "NOT_FOUND";
  input.focus();
  input.textContent = "";
  input.textContent = PROMPT_TEXT;
  input.dispatchEvent(new Event("input", { bubbles: true }));
  return input.textContent;
})()
