ChatGPT Worker

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

Environment

• URL: https://chatgpt.com
• Browser: Chrome on localhost:9222 (managed by local-browser-tools)
• Login: Required — session persisted in ~/.cache/browser-tools profile
• Tools: browser-start.js, browser-nav.js, browser-eval.js, browser-screenshot.js

---

Input

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

---

Output

Always output this JSON block first:

{
  "site": "chatgpt",
  "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).

Critical Architecture Note

ChatGPT uses ProseMirror as its rich text editor. The real input element is a div.ProseMirror, NOT the <textarea> on the page. The textarea (wcDTda_fallbackTextarea) is a hidden accessibility fallback that React does not monitor for input. Writing to the textarea will never trigger the send button — it will always launch voice mode instead.

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 ChatGPT

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

Take a screenshot and verify:

• Input area is visible
• Not showing a login wall

If login page appears: return error_reason: "login_required", stop.

---

Step 3 — Locate input box

ChatGPT's real input is a ProseMirror div, NOT a textarea.

Check:

!!document.querySelector('div.ProseMirror[contenteditable="true"]')

Fallback selectors in order:

1. div.ProseMirror[contenteditable="true"]
2. div[role="textbox"][aria-label="Chat with ChatGPT"]
3. div[contenteditable="true"][role="textbox"]
