🚀 Google Flow Helper (Tampermonkey Userscript)

Google Flow Helper is a lightweight, standalone userscript that unlocks limitations in Google Flow.

It dynamically intercepts and patches API configuration responses on the fly using a remote specification.

Before installing, ensure you have a Userscript Manager extension installed in your browser.

• Tampermonkey (Recommended for Chrome, Edge, Safari, Firefox)
• Violentmonkey (Alternative)

1. Install Tampermonkey: If you haven't already, install the Tampermonkey extension from your browser's web store.
2. Open the Dashboard: Click the Tampermonkey icon in your browser toolbar and select "Create a new script..."
3. Clear the Editor: Delete any default template code currently in the editor.
4. Copy the Script: Open the google-flow-helper.user.js file in this repository, copy the entire code block.
5. Paste & Save: Paste the code into the Tampermonkey editor and press Ctrl + S (or Cmd + S on Mac) to save.
6. Activate: Navigate to https://flow.google.com and refresh the page. You should see the floating panel appear in the bottom right corner!

1. Initialization: The script runs at document-start and injects hooks into XMLHttpRequest.prototype.open and property getters (responseText, response).
2. Targeting: It identifies requests targeting Google's internal /_/AiSandboxAngularFrontend/data/batchexecute endpoint.
3. Spec Fetching: Using GM_xmlhttpRequest (to bypass CORS restrictions), it fetches a JSON specification from a remote server. This spec defines exactly which array index/flag needs to be flipped to bypass limitations.
4. Payload Patching: When the targeted XHR completes, the script parses the response, locates the specific RPC ID (cPZSdc), flips the target boolean flag to true, recalculates the frame length headers, and passes the modified string back to the Google Flow frontend.

• Panel not showing up? Ensure the script is enabled in the Tampermonkey dashboard and that you are on a URL matching https://flow.google.com/*.
• Status says "spec unavailable"? The remote configuration server (flow.cfcnode.com) might be temporarily down. The script will gracefully fail and allow Google Flow to load normally without modifications.
• CSP (Content Security Policy) Errors in Console? Tampermonkey's GM_xmlhttpRequest and unsafeWindow bypass standard browser CORS/CSP limits. If you are using a highly restrictive browser fork, ensure userscript injection is allowed.
