Character Card Editor

The Character Card Editor is Luker's built-in AI-assisted editing tool that lets you modify character card settings and World Info entries using natural language instructions. Every modification made by the AI is presented as a diff comparison for your item-by-item approval before taking effect — ensuring your character card always remains under your control.

AI Edit Popup

For standard character cards without CardApp, clicking the "Open Editor" button opens an AI conversation panel as a popup. You can describe desired modifications in natural language within the popup, and the AI will understand your intent and execute automatically via tool calls.

Supported Operations

The AI in the edit popup can perform the following operations:

• Modify character card fields — Name, description, personality, scenario, first message, example dialogue, system prompt, jailbreak prompt, creator's notes, etc.
• Manage World Info entries — Create, update, delete World Info entries
• Query World Info — Search entries by keyword, query by activation conditions, get entry details
• Set primary World Info — Change the character card's bound primary World Info book
• Simulate Prompt — Preview the actual prompt structure sent to the model under current settings

Diff Approval

After each AI modification, the system displays a diff comparison of the before-and-after content. You can:

• Approve individually — Approve or reject each modification operation separately
• Batch approve — Approve or reject all modifications from the same round at once
• View detailed diff — Expand to see line-by-line differences, with zoom view support
• Rollback — Revert a specific field to a previous version

Only modifications you explicitly approve take effect; rejected modifications are discarded.

Session Management

• Supports multiple editing sessions — you can create, switch, and delete sessions
• Each character retains up to 24 sessions; the earliest sessions are automatically cleaned up when exceeded
• Session content is persistently saved and won't be lost when the popup is closed and reopened

Modification History

All modifications made through the AI are recorded in the modification history. You can:

• View the detailed diff of each modification
• Roll back to any historical version
• Delete individual records or clear all history

World Info Sync

When you import a new character card via replace or update operations, if the old and new character cards are bound to different World Info books, the editor assistant will display a World Info sync popup offering three options:

• Analyze and update with model — AI analyzes the differences between old and new World Info books and intelligently merges them
• Direct replace — Completely replace the old World Info book with the new one
• Don't replace — Keep the existing World Info book unchanged

CardApp Studio

Studio is the editor assistant's full development environment, designed specifically for character cards that contain CardApp. For character cards with CardApp, clicking "Open Editor" automatically opens Studio instead of the popup.

Interface Layout

Studio uses a three-panel layout:

• Left panel — AI conversation area for describing requirements in natural language
• Center area — Live chat interface / CardApp preview
• Right panel — CodeMirror 6-based code editor + file management

Supported Operations

The AI in Studio has a richer toolset than the popup:

CardApp file operations:

• List all files
• Read file contents
• Create or overwrite files
• Patch files (find and replace)
• Delete files
• Rename / move files

Character card field operations:

• Read all editable fields
• Update one or more fields

World Info operations:

• List associated World Info books
• Get World Info entries
• Create, update, delete entries

Code Editor

The right panel integrates a CodeMirror 6 editor with support for:

• Syntax highlighting (automatic file type detection)
• File switching and management
• Creating new files
• Save and reload

File Change Approval

AI modifications to files also require your approval. The system displays a diff of file changes, and you can choose to approve or reject.

Session Management

• Supports multiple editing sessions — you can create, switch, and delete sessions
• Each character retains up to 20 sessions
• Session content is persistently saved in character state

Version History

Studio records file version history via Git, supporting viewing historical versions and rollback.

Configuration Options

In the editor assistant's settings panel, you can configure:

• World Info sync popup — Whether to enable the World Info sync popup after replacing/updating character cards
• LLM Preset — The prompt preset used by the editor assistant (leave empty to use the current preset)
• API Preset — The API connection configuration used by the editor assistant (leave empty to use the current configuration)
• Tool call retry count — Number of retries when the AI returns invalid tool calls
