# PSCT → Lua

Generate working YGOPro Lua card scripts from English PSCT (Problem-Solving
Card Text).

Backed by **Qwen2.5-Coder-7B-Instruct** fine-tuned (LoRA) on ~13,000 real
card scripts from the `ygopro-scripts-master` repo, paired with their
English text from `cards_en.cdb`. Scripts in the cookbook section of the
[YGOPro Scripting Guide](https://github.com/ygopro/scripts) were
oversampled (5×) so the model has strong priors for canonical patterns.

## How it works

1. You paste a card's English text into the textarea
2. The model produces a complete `cXXXX.initial_effect(c)` Lua script
3. You copy the script into your YGOPro `script/` folder

## Caveats

- Runs on the free 2-vCPU CPU tier → **60-120 seconds per card**.
- Output is a starting point — review before using in production. The model
  is ~85-95% accurate on simple cards (draw, destroy, search), ~60-75% on
  multi-clause cards. Boss monsters with archetype-specific bookkeeping are
  largely out of distribution.
- Always verify by loading the generated script into YGOPro and probing
  the actual behavior in a duel.
