## Usage

```python
import json

# Load tasks
tasks = []
with open("data/tasks.jsonl") as f:
    for line in f:
        tasks.append(json.loads(line))

# Each task has: task_id, title, dimension, max_score, prompt_template
print(tasks[0]["prompt_template"])
```

## Evaluation

```bash
pip install -e .
python -m src.evaluate_v2 --task T01 --response "your model output" --breakdown
```
