-# Multi-Page Automation Chrome Extension — Implementation Plan
-
-> **For agentic workers:** REQUIRED: Use superpowers:subagent-driven-development (if subagents available) or superpowers:executing-plans to implement this plan. Steps use checkbox (`- [ ]`) syntax for tracking.
-
-**Goal:** Build a Chrome extension (MV3) that automates a 9-step OAuth registration workflow across VPS panel, OpenAI auth, QQ Mail, and ChatGPT, controlled via a persistent Side Panel.
-
-**Architecture:** Side Panel (UI control) ↔ Background Service Worker (orchestration, state, tab management) ↔ Content Scripts (per-domain DOM automation). All state in `chrome.storage.session`. Unified message protocol across all components. Shared `utils.js` for DOM utilities.
-
-**Tech Stack:** Chrome Extension Manifest V3, vanilla JS, Chrome APIs (sidePanel, tabs, webNavigation, storage, scripting)
-
-**Spec:** `docs/superpowers/specs/2026-04-05-multi-page-automation-extension-design.md`

-```
-
-Also add to the top of `background.js`, after the LOG_PREFIX line:
-
-```js
-importScripts('data/names.js');
-```
-
-And update the `EXECUTE_STEP` handler in `handleMessage` to save email when step 3 is called from sidepanel:
-
-```js
-case 'EXECUTE_STEP': {
-  const step = message.payload.step;
-  // Save email if provided (from side panel step 3)

-
-- [ ] **Step 3: Reload extension, verify no errors**
-
-Reload extension. Open Service Worker DevTools — confirm no syntax errors. Open Side Panel — confirm step buttons still work.
-

-
-## Notes for the implementer
-
-### About TODO selectors
-
-Every content script has `// TODO: Adjust selector` comments. These are intentional — the actual DOM selectors for VPS panel, OpenAI auth, QQ Mail, and ChatGPT **must be determined by inspecting the live pages in DevTools**. The placeholder selectors are educated guesses. Tasks 10-12 are specifically for this selector tuning.
-
-### Debugging workflow
-
-When a step fails:
-1. Check Side Panel log — it shows what went wrong
-2. Open DevTools on the target tab — look for `[MultiPage:xxx]` console messages
-3. Open Service Worker DevTools — look for `[MultiPage:bg]` messages
-4. Use Elements tab to find the correct selector
-5. Update the content script, reload extension, retry
-
-### Chrome extension reload
-
-After modifying any file:
-1. Go to `chrome://extensions`
-2. Click the reload (↻) button on the extension card
-3. Refresh any open tabs that use content scripts (or close and reopen)
-4. Reopen Side Panel if it was open

-# Multi-Page Automation Chrome Extension - Design Spec
-
-## Overview
-
-A Chrome extension that automates a multi-step OAuth account registration and verification workflow. The extension operates across multiple websites (VPS panel, OpenAI auth, QQ Mail, ChatGPT) using a Side Panel as the control center and Content Scripts for DOM manipulation.
-
-## User Story
-
-The user needs to repeatedly perform a multi-step workflow involving:
-1. Getting an OAuth link from a VPS panel
-2. Registering a new account on the linked auth page (multi-page: email/password → verify code → name/birthday)
-3. Receiving email verification codes (twice: registration + login)
-4. Logging into ChatGPT with the new account
-5. Completing OAuth callback verification
-
-The extension automates DOM interactions at each step, with the user triggering steps manually via the Side Panel (semi-automatic mode, with future upgrade to full automation).
-

-
-### Components
-
-- **Side Panel**: Persistent right-side panel showing all steps with action buttons, status indicators, shared data display (OAuth URL, email, etc.), debug log area, and a reset button. On open/reload, restores full state from `chrome.storage.session`.
-- **Background Service Worker**: Central dispatcher and orchestrator. Manages tab creation/switching, stores flow state in `chrome.storage.session` (NOT in-memory, as MV3 service workers can be terminated after 30s of inactivity), relays and routes messages between Side Panel and Content Scripts, and handles tab-switching choreography between steps.
-- **Content Scripts**: Per-domain scripts injected into target pages, each responsible for DOM operations (reading, filling forms, clicking buttons). All share `utils.js` for common utilities.
-
-### Communication — Unified Message Protocol
-
-All messages between components use a standard format:
-```js
-{
-  type: "ACTION_NAME",    // e.g. "FILL_SIGNUP", "CODE_FOUND", "STEP_COMPLETE", "STEP_ERROR", "LOG"
-  source: "qq-mail",      // sender identifier
-  target: "signup-page",  // intended receiver (optional, Background uses for routing)
-  step: 4,                // which workflow step this relates to
-  payload: { ... },       // data
-  error: null             // error message string (if any)
-}
-```
-
-**Message routing:**
-- Side Panel <-> Background: `chrome.runtime.sendMessage`
-- Background -> Content Script: `chrome.tabs.sendMessage` (only after content script reports ready)
-- Content Script -> Background: `chrome.runtime.sendMessage`
-- Background is the central router: it receives all messages and forwards to the correct target based on `target` field and `tabRegistry`.
-
-### Content Script Readiness Protocol
-
-Background must NOT send messages to a content script immediately after opening/navigating a tab. Instead:
-1. Content script sends `{ type: "CONTENT_SCRIPT_READY", source: "vps-panel" }` message on load
-2. Background registers the tab as ready in the `tabRegistry`
-3. Only then does Background send action commands to that tab
-4. If Background needs to send a command but the script isn't ready yet, it queues the command and sends it when the ready signal arrives (with a 15s timeout → error)
-
-### Tab Registry
-
-Background maintains a `tabRegistry` in `chrome.storage.session`:
-```json
-{
-  "vps-panel": { "tabId": 123, "ready": true },
-  "signup": { "tabId": 124, "ready": true },
-  "qq-mail": { "tabId": 125, "ready": false },
-  "chatgpt": { "tabId": 126, "ready": true }
-}
-```
-Before operating on a tab, Background checks if the tab still exists via `chrome.tabs.get()`. If the tab was closed, it reopens and waits for the ready signal.
-
-### Tab Switching Orchestration
-
-When a step requires cross-tab coordination (e.g., step 4: get code from QQ Mail → fill into signup page), the orchestration is always handled by Background:
-1. Content script A (e.g., qq-mail.js) sends result to Background: `{ type: "CODE_FOUND", payload: { code: "123456" } }`
-2. Background stores the data in `chrome.storage.session`
-3. Background activates target tab via `chrome.tabs.update(tabId, { active: true })`
-4. Background sends command to Content script B: `{ type: "FILL_CODE", payload: { code: "123456" } }`
-5. Content script B executes and reports `STEP_COMPLETE` or `STEP_ERROR`
-
-Content scripts NEVER communicate directly with each other.
-
-## Workflow Steps
-
-| Step | Button | Executor | Action |
-|------|--------|----------|--------|
-| 1 | Get OAuth Link | `vps-panel.js` | Check VPS login state → Click OAuth login → Click Codex login → Read auth URL → Send to Background |
-| 2 | Open Signup & Click Register | Background + `signup-page.js` | Background opens auth URL in new tab → `signup-page.js` loads and clicks "Register" button |
-| 3 | Fill Email & Password | `signup-page.js` | Read email from Side Panel input (via Background) → Fill email + password (`mimashisha0.0`) → Submit |
-| 4 | Get Signup Verification Code | `qq-mail.js` → Background → `signup-page.js` | Background opens QQ Mail tab → `qq-mail.js` polls for new email from OpenAI → Extracts code → Background switches to signup tab → `signup-page.js` fills code and confirms |
-| 5 | Fill Name & Birthday | `signup-page.js` | After code verification, page transitions to profile form → Fill random English name + random birthday (age 19-25) → Click complete registration |
-| 6 | Login ChatGPT | Background + `chatgpt.js` | Background opens chatgpt.com in new tab → `chatgpt.js` clicks login → Enters email → If password field appears, fills password; otherwise waits for OTP flow → Submit |
-| 7 | Get Login Verification Code | `qq-mail.js` → Background → `chatgpt.js` | Background switches to QQ Mail tab → `qq-mail.js` polls for email newer than step 4's → Extracts code → Background switches to ChatGPT tab → `chatgpt.js` fills code → Login complete |
-| 8 | Complete OAuth | Background (`webNavigation`) + `chatgpt.js` | `chatgpt.js` navigates to step 1's `oauthUrl` → Background captures localhost redirect via `webNavigation` listener → Stores `localhostUrl` |
-| 9 | VPS Verify | `vps-panel.js` | Background switches to VPS panel tab → `vps-panel.js` pastes `localhostUrl` into input → Clicks verify button |
-
-## Content Script URL Matching
-
-| Script | Match Patterns | all_frames |
-|--------|---------------|------------|
-| `utils.js` | (included by all below) | — |
-| `vps-panel.js` | `http://154.26.182.181:8317/*` | false |
-| `signup-page.js` | `https://auth0.openai.com/*`, `https://auth.openai.com/*`, `https://accounts.openai.com/*` | false |
-| `qq-mail.js` | `https://mail.qq.com/*`, `https://wx.mail.qq.com/*` | true |
-| `chatgpt.js` | `https://chatgpt.com/*` | false |
-
-Note: `qq-mail.js` uses `all_frames: true` because old QQ Mail (`mail.qq.com`) renders inbox inside iframes.
-
-## Content Script Details
-
-### utils.js (shared)
-
-Loaded before every content script. Provides:
-
-```js
-// Wait for a DOM element to appear, with timeout
-async function waitForElement(selector, timeout = 10000)
-
-// React-compatible form filling — triggers proper event chain
-function fillInput(el, value) {
-  const nativeInputValueSetter = Object.getOwnPropertyDescriptor(
-    window.HTMLInputElement.prototype, 'value'
-  ).set;
-  nativeInputValueSetter.call(el, value);
-  el.dispatchEvent(new Event('input', { bubbles: true }));
-  el.dispatchEvent(new Event('change', { bubbles: true }));
-}
-
-// Send log message to Side Panel (via Background)
-function log(message, level = 'info')
-
-// Send step result to Background
-function reportComplete(step, data = {})
-function reportError(step, errorMessage)
-
-// Standard ready signal
-function reportReady(source)
-```
-
-### vps-panel.js
-- **Step 1**: Check login state (look for known logged-in DOM indicator); if not logged in → `reportError(1, "VPS panel not logged in, please log in first")`. Then: locate OAuth login button → click → wait for Codex login button to appear → click → wait for auth URL to appear in DOM → read it → `reportComplete(1, { oauthUrl })`
-- **Step 9**: `waitForElement` for URL input field → `fillInput` with `localhostUrl` → click verify button → `reportComplete(9)`
-
-### signup-page.js
-- **Step 2**: On ready, detect if current page has a "Register" / "Sign up" button → click it → `reportComplete(2)`
-- **Step 3**: `waitForElement` for email input → `fillInput` email → `fillInput` password (`mimashisha0.0`) → click submit → `reportComplete(3)`
-- **Step 4 (receiving end)**: `waitForElement` for verification code input → `fillInput` code → click confirm → `reportComplete(4)`
-- **Step 5**: `waitForElement` for name/birthday fields (page transition after code verification) → `fillInput` random first name, last name → `fillInput` random birthday → click complete → `reportComplete(5)`
-- All DOM operations use `waitForElement` before acting
-- All input filling uses `fillInput` (React-compatible)
-
-### qq-mail.js
-- Check login state first; if not logged in → `reportError(step, "QQ Mail not logged in, please log in first")`
-- **QQ Mail version handling**:
-  - Old version (`mail.qq.com`): Content is inside iframes. With `all_frames: true`, the script runs in each frame. Only the frame containing the inbox list should act.
-  - New version (`wx.mail.qq.com`): SPA, no iframes. All content in main frame with dynamic DOM updates.
-- **Polling strategy** (no page refresh):
-  - Click inbox refresh button (or equivalent DOM trigger) every 3 seconds
-  - Observe email list DOM for new entries matching sender filter (e.g., `openai`, `noreply`) or subject filter (e.g., `verify`, `verification`, `code`)
-  - Extract verification code from email preview/snippet if visible, or click into email and extract from body
-  - Log each poll attempt: `log("Polling QQ Mail... attempt 3/20")`
-- **Step 4**: Find email newer than flow start time → extract 6-digit code via regex → `reportComplete(4, { code, emailTimestamp })`
-- **Step 7**: Find email newer than step 4's `emailTimestamp` → extract 6-digit code → `reportComplete(7, { code })`
-- Timeout after 60 seconds (20 attempts) → `reportError(step, "No matching email found after 60s")`
-
-### chatgpt.js
-- **Step 6**: `waitForElement` for login button → click → `waitForElement` for email input → `fillInput` email → submit → detect next state:
-  - If password field appears → `fillInput` password → submit → `reportComplete(6)`
-  - If no password field (OTP flow) → `reportComplete(6, { needsOTP: true })` (code will come from step 7)
-- **Step 7 (receiving end)**: `waitForElement` for code input → `fillInput` code → submit → `reportComplete(7)`
-- **Step 8**: Navigate to `oauthUrl` (from storage) → page will redirect → `log("Navigating to OAuth URL, waiting for redirect...")` → (localhost capture handled by Background)
-
-## Data Flow
-
-Data persisted in `chrome.storage.session` (survives service worker termination), passed between steps:
-
-```
-Step 1  → oauthUrl          (authorization link)
-Step 3  → email, password   (from Side Panel input + hardcoded)
-Step 4  → lastEmailTimestamp (to distinguish step 7's email)
-Step 8  → localhostUrl      (OAuth callback URL)
-```
-
-Additionally stored:
-- `currentStep`: which step is active (for UI restore)
-- `stepStatuses`: `{ 1: "completed", 2: "completed", 3: "running", ... }` (for UI restore)
-- `tabRegistry`: tab ID mapping (for tab management)
-- `logs`: array of log entries (for UI restore)
-- `flowStartTime`: timestamp when flow began (for email filtering)
-
-## Random Data Generation (in Background)
-
-- **English names**: Built-in list of common first names + last names, randomly combined
-- **Birthday**: Current year minus 19-25 years, random month/day, formatted per the target form's expected format

-**UI behaviors:**
-- **Step interlock**: When a step is running, all other buttons are disabled. Next step button stays disabled until previous step succeeds. Failed steps show ❌ and can be retried. Completed steps show ✅ and can be re-run.
-- **State restore**: On Side Panel open/reload, read `currentStep`, `stepStatuses`, `logs`, and all data fields from `chrome.storage.session` and render.
-- **Reset button**: Clears all `chrome.storage.session` data, resets all steps to pending, clears logs. Does NOT close open tabs (user may want them).
-- **Email input**: Editable text field. User pastes DuckDuckGo-generated email here before step 3.
-- **Log area**: Scrollable, auto-scrolls to bottom. Shows timestamp, level (INFO/OK/WARN/ERR), and message. Each content script action logs what it's about to do and the result.
-
-## Debugging & Observability
-
-Every step must be fully debuggable. The user should never be stuck wondering "what went wrong".
-
-### Log Everything
-
-Each content script logs at these checkpoints:
-1. **Step start**: `"Step N started"`
-2. **Waiting for element**: `"Waiting for selector: #email-input..."`
-3. **Element found/not found**: `"Found #email-input"` or `"Timeout waiting for #email-input after 10s"`
-4. **Action taken**: `"Filled email input with xxx@duck.com"`, `"Clicked submit button"`
-5. **Page transition**: `"Page URL changed to https://..."`
-6. **Polling progress**: `"Polling QQ Mail... attempt 5/20, no match yet"`
-7. **Data extracted**: `"Verification code found: 123456"`
-8. **Step result**: `"Step N completed successfully"` or `"Step N failed: [reason]"`
-
-### Error Recovery Guide
-
-When a step fails, the error message should include actionable guidance:
-
-| Error | Guidance shown in log |
-|-------|----------------------|
-| VPS not logged in | "Please log in to VPS panel at http://154.26.182.181:8317 and retry" |
-| QQ Mail not logged in | "Please log in to QQ Mail and retry" |
-| Element not found (timeout) | "Could not find [selector] on [url]. Page may have changed layout. Check DevTools." |
-| Email not received (timeout) | "No matching email after 60s. Check QQ Mail manually. Email may be in spam." |
-| Tab was closed | "Tab [name] was closed. Will reopen on retry." |
-| Content script not ready | "Content script on [url] did not respond in 15s. Try refreshing the tab and retry." |
-| Unknown error | "Unexpected error: [message]. Check DevTools console on [tab name] for details." |
-
-### DevTools Integration
-
-- Each content script logs to the browser console with a prefix: `[MultiPage:vps-panel]`, `[MultiPage:qq-mail]`, etc.
-- Background service worker also logs with `[MultiPage:bg]` prefix.
-- All chrome.storage writes are logged: `[MultiPage:bg] storage.set: stepStatuses = {...}`
-- This allows using Chrome DevTools on any tab or the service worker to see detailed execution trace.
-
-## Robustness
-
-### Login State Detection
-- **VPS panel** (step 1): Check for known logged-in DOM indicator before operating; if absent, `reportError` with guidance and pause.
-- **QQ Mail** (steps 4, 7): Check for inbox DOM indicator; if absent, `reportError` with guidance and pause.
-
-### DOM Element Waiting
-All content script DOM operations use `waitForElement(selector, timeout)` from `utils.js`. Default timeout: 10 seconds. On timeout, `reportError` with the selector and URL for debugging.
-
-### Email Polling
-- Poll QQ Mail inbox every 3 seconds for matching email (filter by sender/subject keywords)
-- Step 7 only accepts emails newer than step 4's `lastEmailTimestamp` to avoid duplicates
-- Each poll attempt is logged with attempt count
-- Timeout after 60 seconds (20 attempts); `reportError` with guidance to check spam folder
-
-### Localhost Redirect Capture
-- `chrome.webNavigation.onBeforeNavigate` listener is registered in Background **only when step 8 starts**
-- Listener matches URL starting with `http://localhost`
-- On capture: store `localhostUrl`, remove listener, `reportComplete(8)`
-- If not captured within 30 seconds: `reportError` with guidance
-- Listener is always removed when step 8 ends (success or failure)
-
-### Page Transitions
-- After form submissions, `signup-page.js` and `chatgpt.js` must handle page navigation/SPA route changes
-- Use `waitForElement` on the NEXT expected element after submission, not just submit and hope
-- If URL changes (full navigation), the content script re-injects and sends a new READY signal; Background re-sends the pending command
-
-## Permissions (manifest.json)
-
-```json
-{
-  "permissions": [
-    "sidePanel",
-    "tabs",
-    "webNavigation",
-    "storage",
-    "scripting",
-    "activeTab"
-  ],
-  "host_permissions": [
-    "http://154.26.182.181:8317/*",
-    "https://auth0.openai.com/*",
-    "https://auth.openai.com/*",
-    "https://accounts.openai.com/*",
-    "https://mail.qq.com/*",
-    "https://wx.mail.qq.com/*",
-    "https://chatgpt.com/*",
-    "http://localhost/*"
-  ]
-}
-```
-
-Note: `scripting` permission enables `chrome.scripting.executeScript` for dynamic injection when the auth flow redirects to unexpected domains.
-
-## Technical Decisions
-
-- **Manifest V3**: Required for current Chrome extension development
-- **Side Panel API**: `chrome.sidePanel` for persistent control panel
-- **Pure Content Script approach**: No external dependencies, direct DOM manipulation
-- **State in `chrome.storage.session`**: MV3 service workers can terminate after 30s idle; all flow state must be persisted, not held in memory
-- **React-compatible form filling**: Use native setter + event dispatch pattern for all React-based target pages
-- **Content script readiness protocol**: Scripts report ready before receiving commands; commands queued if not ready
-- **Unified message protocol**: All inter-component messages use same format with type/source/target/step/payload/error
-- **Shared utils.js**: Common utilities loaded by all content scripts to avoid duplication
-- **Background as sole orchestrator**: All cross-tab coordination goes through Background; content scripts never talk to each other
-- **webNavigation listener scoped to step 8**: Registered on step start, removed on step end, avoids false triggers
-- **Semi-automatic first**: Each step triggered manually, upgrade to full automation later
-- **DuckDuckGo email generation**: Manual step (user clicks DuckDuckGo panel), user pastes email into Side Panel input
-
-## Future Enhancements
-
-- Full automation mode (single button to run all steps)
-- DuckDuckGo API integration for automatic email generation
-- Batch execution support
-- Error recovery and auto-retry logic
-- Export logs for troubleshooting
