# Harness Graders Agent Notes

Graders are reusable scripts or prompts that score eval outputs.

- Code-based graders: shell scripts or test files that check structured outputs deterministically.
- LLM-judge graders: prompt templates that ask a model to score free-text output against a rubric.

Prefer code-based graders. Add LLM-judge graders only when deterministic checking is impossible.
