Google Flow UI Client

Generate images in Google Flow through Chrome CDP + browser UI automation.

Important constraints:

• - Project creation is UI-only
• Prompt submission is UI-only
• Do not use or describe any API-based project creation path
• Images are considered complete once the base images are visible in the browser

Script Directory

Resolve:

1. 1. {baseDir} = directory containing this INLINECODE1
2. Script path = INLINECODE2
3. INLINECODE3 = bun if installed, else INLINECODE5

Consent Check (REQUIRED)

Before first use, verify user consent for reverse-engineered API usage.

Consent file locations:

• - macOS: INLINECODE6
• Linux: INLINECODE7
• Windows: INLINECODE8

Flow:

1. 1. Check if consent file exists with accepted: true and INLINECODE10
2. If valid consent exists → print warning with acceptedAt date, proceed
3. If no consent → show disclaimer, ask user via AskUserQuestion:

- "Yes, I accept" → create consent file with ISO timestamp, proceed
- "No, I decline" → output decline message, stop

1. 4. Consent file format: INLINECODE13

Preferences (EXTEND.md)

Check EXTEND.md existence (priority order):

CODEBLOCK0

EXTEND.md Supports: Default model | Default aspect ratio | Custom data directory

Execution Envelope (REQUIRED)

Before any pre-flight check or main.ts invocation, decide one shell environment and reuse it for every command in the run.

• - Use the same INLINECODE15
• Use the same proxy variables
• Use the same CDP / Chrome profile variables

If you set any of these once, keep them identical for all later commands in the turn:

• - INLINECODE16
• INLINECODE17
• INLINECODE18 / INLINECODE19
• INLINECODE20
• INLINECODE21 / INLINECODE22
• INLINECODE23
• INLINECODE24
• INLINECODE25
• INLINECODE26

Never run pre-flight checks in one environment and main.ts in another.

Preferred proxy setup:
CODEBLOCK1

Usage

Before running any generation command, complete the Pre-flight Checks below.

CODEBLOCK2

Batch mode rules:

• - Use one command with repeated INLINECODE28
• The first prompt creates a new project through the UI unless --project-id is supplied
• Later prompts reuse that same project
• Do not run multiple separate main.ts commands for a multi-prompt batch

---

Pre-flight Checks

Run these checks in order. Each step must pass before moving to the next.

Step 1: Runtime Prerequisites (BLOCKING)

Check the Bun runtime and Python:

CODEBLOCK3

If any required command is missing, stop.

If running under WSL, also verify the Windows bridge and Chrome path assumptions:

CODEBLOCK4

If not running under WSL, ensure FLOW_WEB_CHROME_PATH is set before continuing.

Step 2: Browser Profile Check (AUTO-RESOLVE)

Check if the Chrome debug user data directory exists. Default WSL-visible path:

• - INLINECODE32
• env override: INLINECODE33

CODEBLOCK5

• - EXISTS → proceed
• INLINECODE35 → proceed, but tell the user a fresh browser profile will be created

Step 3: Network Connectivity Check (WARN + WAIT)

Test Google reachability using the same environment you will use for main.ts:

CODEBLOCK6

• - 200/301/302 → proceed
• INLINECODE38 → stop and fix proxy settings first

Do not continue into main.ts while shell networking and browser proxy settings disagree.

Step 4: Login State Check (WARN + GUIDE)

Check if cached credentials exist:

Linux default cookie file:

• - INLINECODE40

CODEBLOCK7

• - EXISTS → proceed
• INLINECODE42 → run:

  ${BUN_X} {baseDir}/scripts/main.ts --login --verbose
  

Then wait for the user to finish Google login in the browser.

Generation Rules

The skill supports exactly two generation entry modes:

• - New project: omit --project-id; the script creates a project through the Flow UI
• Existing project: provide INLINECODE44

Do not invent any third path.

Explicitly forbidden:

• - API-based project creation
• Describing API project creation as a fallback
• Mixing one failed path with a different project-creation mechanism mid-run

If automatic UI project creation fails:

1. 1. Inspect the Flow listing page in the browser
2. Fix the UI state only
3. Retry the same UI path
4. If needed, manually click 新建项目 in the browser, capture the resulting project id from the URL, then rerun main.ts with INLINECODE47

The fallback is still UI-only.

---

Task Completion (IMPORTANT)

INLINECODE48 only automates the UI. It fills the prompt, clicks Create, then exits immediately. Actual image generation continues asynchronously in the browser.

After main.ts exits with code 0:

1. 1. The script has successfully submitted all prompts. Images are now generating in the browser.
2. You MUST verify generation completion by taking a browser screenshot (via CDP or screenshot tool) and visually checking whether images have appeared on the page.
3. If the screenshot shows images are still loading (spinner, progress indicator, blank placeholders), wait 10-15 seconds and take another screenshot.
4. Repeat until all images are visible, or until 2 minutes have passed (then report a timeout).
5. Once the base images are confirmed visible, stop and report completion.
6. Do NOT download, fetch, curl, or render any URLs. Images are visible in the browser.

Important completion rule:

• - If the images are visible and Flow still shows optional HD-enhancement / download / post-processing toasts, treat the task as complete anyway.

If the script exits with a non-zero code, report the error and stop.

Optional Verification Helper

If /home/admin1/.openclaw/workspace/scripts/agent-browser-cdp.sh exists, it is a convenient helper for screenshots and browser inspection after generation:

CODEBLOCK9

This helper is optional. Generation must not depend on agent-browser being installed.
