Admin Debug Context

Performance guarantee

The entire debug system is zero cost for non-admins:

• AdminIndicatorWrapper checks selectIsAdmin from Redux and returns null immediately if false
• Both AdminIndicatorIsland (ssr layout) and DynamicAdminIndicatorWrapper (authenticated layout) use dynamic(..., { ssr: false }) — the admin bundle never downloads for non-admins
• useDebugContext is a no-op when isAdmin is false — no dispatch, no effect, no render cost

What is auto-captured (no route work needed)

AdminDebugContextCollector runs at layout level inside AdminIndicatorWrapper. For every admin session it automatically captures:

Data	How
Current pathname	usePathname() on every navigation
Search params	useSearchParams() on every navigation
Browser viewport	window.innerWidth/Height
User agent	navigator.userAgent
Navigation count	increments on each pathname change
console.error calls	patches console.error while mounted
unhandledrejection events	window.addEventListener
window.error events	window.addEventListener

This is available instantly in the "Copy Full Context" snapshot even for routes that add zero custom debug code.

Adding route/feature debug data

The hook — use this everywhere

import { useDebugContext } from '@/hooks/useDebugContext';

export default function MyComponent({ sessionId }: { sessionId: string }) {
    const session = useAppSelector(s => selectSession(s, sessionId));
    const { publish, isActive } = useDebugContext('Chat');  // namespace

    useEffect(() => {
        publish({
            'Session ID': sessionId,
            'Status': session?.status,
            'Message Count': session?.messages.length,
            'Conversation ID': session?.conversationId,
        });
    }, [isActive, session?.status, session?.messages.length, sessionId]);
}

Key rules:

• First arg is the namespace — appears as group header in the debug panel
• Keys are auto-prefixed: "Chat:Session ID", "Chat:Status", etc.
• isActive is true only when isAdmin && isDebugMode — use it in useEffect deps to gate expensive collection
• The hook auto-clears all namespace keys on unmount — no manual cleanup needed
• Safe in any component tree — pure no-op for non-admins

Hook API

const { publish, publishKey, isActive } = useDebugContext('Namespace');

publish({ 'Key': value, 'Other Key': otherValue });  // merge namespaced data
publishKey('Key', value);                             // set single key
isActive  // boolean — true only when admin AND debug mode is on

---

Adding a debug module panel

For richer feature-specific UIs (not just JSON data), create a debug module:

Step 1 — Create the component

// components/admin/debug/MyFeatureDebug.tsx
'use client';
import { useAppSelector } from '@/lib/redux/hooks';

export default function MyFeatureDebug() {
    // Read exclusively from Redux selectors — no local fetch, no useState for data
    const data = useAppSelector(selectSomething);
    return <div className="p-4 text-xs font-mono">{JSON.stringify(data, null, 2)}</div>;
}

Step 2 — Register in the registry

// components/admin/debug/debugModuleRegistry.tsx
import MyFeatureDebug from './MyFeatureDebug';
import { Zap } from 'lucide-react';

export const debugModules: DebugModule[] = [
    // ... existing modules ...
    {
        id: 'my-feature',
        name: 'My Feature',
        icon: Zap,
        component: MyFeatureDebug,
        description: 'Live state of my feature',
        color: 'text-purple-400',
    },
];

The icon appears in the MediumIndicator debug row. Clicking opens the panel modal. Component only mounts when the panel is open — zero overhead when closed.

Copy Full Context — the AI agent workflow

The Copy button in LargeIndicator assembles a complete markdown snapshot:

# Admin Debug Context Snapshot
Generated: 2026-03-27T10:42:00.000Z
Admin: admin@example.com

## Route
- **Path:** /demos/chat/c/abc-123
- **Viewport:** 1440×900
- **Render Count:** 3

## API Config
- **Active Server:** localhost
- **Backend URL:** http://localhost:8000
- **Health:** healthy (42ms)

## Feature Debug Data
### Chat
- **Session ID:** sess-xyz
- **Status:** streaming
- **Message Count:** 7

## Recent API Calls
| Status | Method | Path | HTTP | Duration |
...

## Console Errors
No errors captured.

Workflow: Admin sees a bug → opens LargeIndicator → clicks Copy → pastes into AI agent chat. Agent gets full context: what page, what state, what the API is doing, any errors.

Viewing debug context

1. Small indicator — two colored dots (server env, health)
2. Medium indicator — debug icon row; click any icon for that feature's panel
3. Large indicator — full admin dashboard:
   • Copy button (always visible) — one click to copy everything for an AI agent
   • Console Errors panel — auto-captured, collapsible, shows stack traces
   • Debug Data section (debug mode on) — namespaced JSON from useDebugContext
   • API calls log and all environments health grid

Enable debug mode: click the Debug toggle in MediumIndicator or LargeIndicator.
