📄 Description

Changelog Entry

Description

Implements automatic Chat Context injection that adds recent or pinned chat history to conversation context.
I believe this feature will enhance the user experience by personalizing model context. Find an example in the screenshot below.

Added

Backend config: ENABLE_CHAT_CONTEXT, CHAT_CONTEXT_MODE, CHAT_CONTEXT_TOP_K in config.py
Middleware handler chat_context_handler() in utils/middleware.py supporting:
- Recent mode: retrieves last N chats (skip=1 to exclude current)
- Pinned mode: retrieves user-pinned chats (early return if none exist)
- Structured extraction: first_user_message + last_messages{user, assistant}
- Conditional prompts: encouraging for pinned, discouraging for recent
- JSON-in-XML injection format
Admin UI in General.svelte: enable toggle, mode dropdown, top K input
Feature flag in Chat.svelte: checks $config.chat_context.enable
Config exposure via /api/config endpoint

Changed

AdminConfig model now includes chat context fields
get_admin_config() and update_admin_config() handle chat context settings
Middleware pipeline calls chat_context_handler() when feature enabled

Additional Information

Design decisions:

Skip=1 in recent mode prevents self-reference
No skip in pinned mode
Early return for empty pinned chats
Multimodal content support extracts text from arrays

Chat format injected:
```json
[
{
"title": "Chat Title",
"created_at": "2024-01-15T10:30:00-0500",
"updated_at": "2024-01-15T11:45:00-0500",
"first_user_message": "...",
"last_messages": {
"user": "...",
"assistant": "..."
}
}
]
```

Testing: Manual testing of enable/disable, mode switching, top K validation, pinned empty/full, recent mode, config persistence, feature flag, JSON structure, multimodal handling.
