# Rubrics

## Definition

Rubrics turn policies into reviewable checks for a specific output. A good rubric makes pass, fail, or incomplete evidence explainable without replacing the policy it tests.

Use this reference when a benchmark failure needs to show exactly which condition a candidate output satisfied or violated.

## Fields, states, or lifecycle rules

- Rubrics should be tied to a policy and an applicability boundary.
- A binary rubric should be narrow enough to judge one output clearly.
- Linked Cases make the intended boundary concrete; they do not replace the Rubric's applicability rule.
- Overlapping rubrics can make failures hard to interpret.
- Rubric versions matter when pass/fail logic changes between benchmark runs.
- This page describes rubric semantics, not a public scoring API.

Rubrics should be read with [Policies](/docs/object-model/policies), [Applicability logic](/docs/object-model/applicability-logic), [Writing Binary Rubrics](/docs/correctness-governance/binary-rubrics), and [Overlapping rubrics](/docs/troubleshooting/overlapping-rubrics).

{% example-demo title="Rubrics boundary" %}
Policy: Compatibility claims require explicit source support.

Rubric: Pass only if the answer cites explicit compatibility support or states that compatibility is uncertain.

Interpretation: A candidate output that simply says "yes, it works" fails because the rubric names the missing evidence.

## Source confidence

Code-backed: Rubric types and list/detail routes expose criteria, Policy and Case links, applicability, and versioned evaluation context. The reference explains product semantics and does not promise a public scoring schema.
