# PageAgentExt Architecture
|
||||
|
||||
MV3-compliant Chrome extension architecture.
|
||||
|
||||
## Design Principles
|
||||
|
||||
1. **Service Worker is stateless** - Only relays messages, no state
|
||||
2. **Agent runs in SidePanel** - All agent logic lives there
|
||||
3. **Unidirectional communication** - Agent → SW → Content
|
||||
4. **Storage-based coordination** - Mask state via chrome.storage
|
||||
|
||||
## Environments
|
||||
|
||||
### 1. Side Panel (Agent Host)
|
||||
|
||||
**Files:** `src/entrypoints/sidepanel/`
|
||||
|
||||
- Hosts `PageAgentCore` and execution loop
|
||||
- Manages `TabsManager` for multi-tab control
|
||||
- Uses `RemotePageController` for RPC to content script
|
||||
- Writes agent state to storage for mask coordination
|
||||
|
||||
**Key Components:**
|
||||
|
||||
- `AgentController` - Agent lifecycle, writes `agentState` to storage
|
||||
- `useAgent` hook - React integration
|
||||
- `App.tsx` - Main UI
|
||||
|
||||
### 2. Background (Service Worker)
|
||||
|
||||
**File:** `src/entrypoints/background.ts`
|
||||
|
||||
**Only two responsibilities:**
|
||||
|
||||
1. Relay `AGENT_TO_PAGE` messages to content script
|
||||
2. Broadcast `TAB_CHANGE` events
|
||||
|
||||
**No state, no agent logic.**
|
||||
|
||||
### 3. Content Script
|
||||
|
||||
**File:** `src/entrypoints/content.ts`
|
||||
|
||||
- Hosts `PageController` (lazy-initialized)
|
||||
- Handles RPC messages for DOM operations
|
||||
- Polls storage every 1s for mask state
|
||||
- Uses `document.visibilityState` to manage mask visibility
|
||||

||||

|

```
|
||||
|
||||
## Message Protocol
|
||||
|
||||
Only two message types:
|
||||
|
||||
| Type | Direction | Purpose |
|
||||
|------|-----------|---------|
|
||||
| `AGENT_TO_PAGE` | SidePanel → SW → Content | RPC call to PageController |
|
||||
| `TAB_CHANGE` | SW → All | Tab events broadcast |
|
||||
|
||||
### RPC Methods
|
||||
|
||||
- State: `getCurrentUrl`, `getLastUpdateTime`, `getBrowserState`
|
||||
- DOM: `updateTree`, `cleanUpHighlights`
|
||||
- Actions: `clickElement`, `inputText`, `selectOption`, `scroll`, `scrollHorizontally`, `executeJavascript`
|
||||
- Lifecycle: `dispose`
|
||||
|
||||
## Mask Management
|
||||
|
||||
Mask visibility is managed autonomously by content script via storage polling.
|
||||
|
||||
### Storage State
|
||||
|
||||
```typescript
|
||||
interface AgentState {
|
||||
tabId: number | null // Agent's current tab
|
||||
running: boolean // Agent is executing
|
||||
}
|
||||
// Key: 'agentState'
|
||||
```
|
||||
|
||||
### Content Script Logic
|
||||
|
||||
```typescript
|
||||
setInterval(async () => {
|
||||
const { agentState } = await chrome.storage.local.get('agentState')
|
||||
|
||||
const shouldShow =
|
||||
agentState?.running &&
|
||||
agentState?.tabId === myTabId &&
|
||||
document.visibilityState === 'visible'
|
||||
|
||||
if (shouldShow) showMask()
|
||||
else hideMask()
|
||||
}, 1000)
|
||||
```
|
||||
|
||||
### Agent Updates Storage
|
||||
|
||||
- Task start: `{ tabId, running: true }`
|
||||
- Tab switch: `{ tabId: newTabId, running: true }`
|
||||
- Task end: `{ tabId: null, running: false }`
|
||||
|
||||
## Multi-Tab Control
|
||||

### Tab Types
|
||||
|
||||
- **Initial Tab** - Where user started the task
|
||||
- **Managed Tabs** - Tabs opened by agent via `open_new_tab`
|
||||
|
||||
### Tab Grouping
|
||||
|
||||
Agent-opened tabs are grouped in Chrome tab group `Task(<taskId>)`.

||||

||||

## Security
|
||||
|
||||
1. **API Key Storage** - Keys in `chrome.storage.local`
|
||||
2. **Content Script Isolation** - Runs in isolated world
|
||||
3. **Tab Restriction** - Agent only controls its own tabs
