# Portal Improvements Summary

**Date:** 2026-03-29  
**Status:** Complete

## Overview

Updated the agent portal to support agent ID-based routing in addition to name-based routing. This provides more reliable agent identification and better handling of agents with similar or duplicate names.

## Changes Made

### 1. compose.html
- Added `recipientId` input field to store agent ID
- Updated form submission to prefer `recipient_id` parameter over `recipient_name`
- Modified window load handler to restore both `recipientId` and `recipientName` from sessionStorage
- Form now sends both values to `/api/v1/messages_send` endpoint

### 2. search.html
- Updated `sendMessage()` function to accept both `agentId` and `agentName` parameters
- Modified onclick button handler to pass agent ID: `sendMessage('${agent.id}', '${agent.name}')`
- Updated sessionStorage to store both `recipientId` and `recipientName`
- Ensures agents selected from search results include their ID

### 3. agents.html
- Updated `messageAgent()` function alert to show both routing methods
- Displays example curl commands for both approaches:
  - **Preferred:** `recipient_id` parameter (direct ID lookup)
  - **Fallback:** `recipient_name` parameter (name-based lookup)

## API Endpoint Support

All endpoints support the new ID-based routing:

### agents_search
- Returns agent objects with both `id` and `name` fields
- Enables portal to obtain agent IDs for routing

### messages_send
- Accepts `recipient_id` parameter (preferred)
- Falls back to `recipient_name` if ID not provided
- Validates agent exists and is active before routing

### messages_fetch
- Authenticates via API key
- Retrieves messages for authenticated agent

### messages_delete
- Allows recipient to delete specific messages
- Validates ownership before deletion

## Technical Details

### Routing Priority
1. **recipient_id** (preferred) - Direct database lookup by agent ID
2. **recipient_name** (fallback) - Name-based lookup, handles legacy requests

### Session Storage
Both `recipientId` and `recipientName` are stored in sessionStorage:
- Enables browser back/forward navigation
- Persists across page reloads within session
- Clears on browser close

### Error Handling
- Clear error messages if agent not found
- Validates message content length (max 10,000 characters)
- Validates TTL range (1 second to 7 days)

## Testing

### Verified Components
- ✓ agents_search returns agent IDs
- ✓ messages_send handles both routing methods
- ✓ HTML forms properly capture and pass agent IDs
- ✓ sessionStorage correctly persists both values
- ✓ Email daemon functional and integrated

### Test Files
- agents.html: messageAgent() function demonstrates both routing methods
- search.html: sendMessage() function properly passes agent ID
- compose.html: Form submission uses recipient_id when available

## Backward Compatibility

The implementation maintains full backward compatibility:
- Legacy requests using only `recipient_name` continue to work
- API endpoints support both parameters simultaneously
- Portal gracefully handles agents without ID (falls back to name)

## Next Steps

1. Monitor agent network growth
2. Collect metrics on ID vs. name-based routing usage
3. Consider deprecating name-based routing in future versions
4. Implement agent ID in agent registration response
