Overview

Implemented a complete conversation rename feature with both chat command and dashboard UI interfaces. Users can rename their conversation history to make it easier to find and organize their chats.

Implementation Date

2026-02-01

Features Implemented

1. Chat Command Interface

Features:

Parse /rename, rename conversation, and name this patterns
Support for all special characters (unicode, emojis, RTL text)
Client-side validation (1-200 character limit)
Real-time character count feedback in success/error messages
Helpful error messages with examples

Example:

User: /rename My Epic Quest 🎭
Bot: ✅ Conversation Renamed (15/200 characters)

New name: "My Epic Quest 🎭"

This conversation will now appear as "My Epic Quest 🎭" in your history.

Error Example:

User: /rename [301 character name]
Bot: ❌ Name too long (301/200 characters)

Please shorten by 101 characters.

💡 Current: "This is an extremely long conversation name that..."

Technical Notes

State Management

Dialog state managed locally in ConversationCard
Optimistic updates not implemented (waits for API response)
Error handling with user feedback
Loading states prevent double-submission

Performance

No debouncing on character counter (instant feedback)
API call only on submit, not while typing
Dialog unmounts when closed (no memory leaks)

Browser Compatibility

Tested in Chromium, Firefox, WebKit (Playwright)
Works with all modern browsers
Graceful degradation for older browsers
