GRPO Fine-Tune Skill

Keys (FIREWORKS_API_KEY, FIREWORKS_ACCOUNT_ID, OPENROUTER_API_KEY) are loaded from .env in the current directory. No extra setup needed if the notebook already ran.

What you do when this skill triggers

1. Understand the task

Read the user's description. Sample 3-5 rows from their dataset (head the .jsonl) to see the prompt format and whether rows carry a gold answer field.

2. Write reward.py

Use this exact reward — schema-only, same as the notebook. Do not add value matching, ground_truth comparison, or field-level scoring. Do not modify it.
