ChatGPT Pro Oracle

ChatGPT Pro Oracle

Send prompts to ChatGPT (including project GPTs) via Playwriter and get responses back. Connects to your existing Chrome session - no need to quit Chrome or manage cookies.

When to use

• Cross-validate complex reasoning with a second model
• Leverage GPT-5.2 Pro's extended thinking for research tasks
• Query a ChatGPT Project that has custom instructions/​files

Requirements

• Chrome with Playwriter extension installed and activated on at least one tab
• User must be logged into ChatGPT in Chrome
• Package: npm install -g @erwinkn/​chatgpt-oracle

Configuration

Set CHATGPT_ORACLE_URL to use a custom default URL (e.g., a ChatGPT Project).

Option 1: .env file in repo root

# .env
CHATGPT_ORACLE_URL="https://chatgpt.com/​g/​g-p-.../​project"

Option 2: Environment variable

export CHATGPT_ORACLE_URL="https://chatgpt.com/​g/​g-p-.../​project"

If not set, defaults to https://chatgpt.com/.

As a module

import { askChatGPT, sendChatGPT, pollChatGPT, continueChatGPT } from '@erwinkn/​chatgpt-oracle';

// Standard usage - wait for response
const result = await askChatGPT({
  prompt: 'Your question here',
  model: 'pro'
});
console.log(result.response);
console.log(result.sessionId); // Use for follow-ups

// Async mode - send and poll later
const { sessionId } = await sendChatGPT({ prompt: 'Complex question' });
// ... do other work ...
const pollResult = await pollChatGPT({ sessionId, wait: true });

// Follow-up in same conversation
const followUp = await continueChatGPT({
  sessionId: result.sessionId,
  prompt: 'Follow-up question'
});

Functions

askChatGPT(options) - Standard usage

Sends a prompt and waits for the complete response.

Returns:

{ success, response, url, sessionId, elapsed, timedOut, error }

sendChatGPT(options) - Async mode

Sends a prompt and returns immediately with a session ID for polling.

Returns:

{ success, sessionId, url, error }

pollChatGPT(options) - Check/​wait for response

Checks if a response is ready or waits for completion.

Returns:

{ success, complete, response, url, sessionId, elapsed, timedOut, error }

continueChatGPT(options) - Follow-up messages

Sends a follow-up message in an existing conversation.

Returns:

{ success, response, url, sessionId, elapsed, timedOut, error }

Utility functions

• closeSession(sessionId) - Close an active session and clean up resources
• listSessions() - List all active sessions with their elapsed time

Models

• auto: ChatGPT decides how long to think
• instant: Fast responses
• thinking: Extended thinking for complex questions
• pro: Research-grade intelligence (can take 10+ minutes)

Examples

Simple question

import { askChatGPT } from '@erwinkn/​chatgpt-oracle';

const result = await askChatGPT({
  prompt: 'What are the key differences between REST and GraphQL?',
  model: 'instant'
});

With a project GPT

import { askChatGPT } from '@erwinkn/​chatgpt-oracle';

const result = await askChatGPT({
  url: 'https://chatgpt.com/​g/​g-p-69590661701c8191958b62e91c543dfb/​project',
  prompt: 'Review this architecture decision',
  model: 'pro',
  timeout: 1800000  // 30 min for complex analysis
});

With file attachments

import fs from 'node:fs';
import { askChatGPT } from '@erwinkn/​chatgpt-oracle';

const result = await askChatGPT({
  prompt: 'Find bugs in this code',
  files: [
    { path: 'src/​main.py', content: fs.readFileSync('src/​main.py', 'utf-8') }
  ]
});

Async mode with polling

import { sendChatGPT, pollChatGPT } from '@erwinkn/​chatgpt-oracle';

// Start a long-running request without blocking
const { sessionId, url } = await sendChatGPT({
  prompt: 'Analyze this complex codebase architecture',
  model: 'pro'
});
console.log(`Started session: ${sessionId}`);

// Do other work while waiting...

// Check if ready (non-blocking)
let result = await pollChatGPT({ sessionId });
if (!result.complete) {
  console.log(`Still working... ${result.elapsed}s elapsed`);
  // Wait for completion
  result = await pollChatGPT({ sessionId, wait: true });
}
console.log(result.response);

Multi-turn conversation

import { askChatGPT, continueChatGPT } from '@erwinkn/​chatgpt-oracle';

// Initial question
const first = await askChatGPT({
  prompt: 'Explain the SOLID principles',
  model: 'pro'
});

// Follow-up using the same session
const second = await continueChatGPT({
  sessionId: first.sessionId,
  prompt: 'Can you give examples in TypeScript?'
});

// Another follow-up
const third = await continueChatGPT({
  sessionId: first.sessionId,
  prompt: 'How does this apply to React components?'
});

Long-running requests

GPT-5.2 Pro can take 10+ minutes for complex tasks. Use sendChatGPT + pollChatGPT for async operation, or run as a background task in Claude Code.

Troubleshooting

• "Extension not running": Click the Playwriter extension icon in Chrome on any tab (icon should turn green)
• "Failed to connect": The CLI auto-retries and kills stale processes. If persistent:
  • Ensure Chrome is running with Playwriter extension active
  • Run lsof -ti:19988 | xargs kill -9 to clear stuck processes
• Model not switching: ChatGPT may have changed their UI; check data-testid values
• Empty response: Increase timeout (-t flag) or check if ChatGPT is rate-limiting
