Lorcana Card Migration

Interactive migration of Lorcana card definitions from legacy format to the new @tcg/lorcana-types format.

When to Use

• User requests to migrate a specific card from legacy format
• User wants to implement cards from packages/lorcana-cards
• Batch migration of successfully-parsed cards is needed
• Interactive card development with parser validation

Process

Input

Card Identifier: Card ID (e.g., 007-heihei-boat-snack) or filename

Workflow

1. Read Legacy Card

   • Locate file in src/legacy-cards/001/{type}/{file}.ts
   • Extract properties: id, name, version, cost, abilities, etc.

2. Parse Abilities

   • Run parser V2 on each ability text
   • Determine parse success/failure

3. Interactive Confirmation

   • For each ability: show parsed result, ask for confirmation
   • On failure: ask for clarification or suggest interpretation
   • Manual overrides can be added during migration

4. Generate New Card

   • Create file at src/cards/001/{type}/{number}-{name}.ts
   • Map legacy properties to new format
   • Include confirmed parsed abilities

5. Update Index

   • Add export to appropriate index file

6. Cleanup Prompt

   • Ask: "Delete legacy file? (yes/no)"
   • Only delete after explicit confirmation

Property Mapping

Ability Types

After parsing, abilities become one of:

• keyword: { type: "keyword", keyword, value? }
• triggered: { type: "triggered", name?, trigger, effect }
• activated: { type: "activated", cost?, effect }
• static: { type: "static", name?, effect }
• action: { type: "action", effect }
