Rubric

A rubric is a structured set of explicit criteria and guidance for evaluating and assigning judgments or scores to an output, artifact, or behavior.

How 4 Manning books explain it

Build an AI Agent (From Scratch)

An explicit framework of criteria and performance standards for judging the quality or success of an output.

How it is used
Gives human evaluators and LLM judges explicit criteria for assessing open-ended agent behavior.
How deep it goes
Develops criteria from trace review and failure taxonomy, then specifies PASS/FAIL decisions, aggregate metrics, and an LLM-judge prompt.
Examples
Uses PASS/FAIL checks for answer relevancy, citation reliability, and requirement compliance in a research-agent evaluation prompt.
What you can do after
Build it from scratch by converting observed failures into criteria and using them to grade responses and track pass rates.

AI Agents in Action, Second Edition

A rubric is a structured set of criteria and standards for evaluating the quality of an output or behavior.

How it is used
Evaluates open-ended agent outputs against explicit quality criteria when a single correct answer or accuracy score is insufficient.
How deep it goes
Develops objectives, criteria, scales, thresholds, human validation, and a critic-agent workflow rather than stopping at a definition.
Examples
Uses recommendation criteria and an image-style critic with a five-point scale, pass threshold, and typed feedback.
What you can do after
Build it from scratch for an open-ended output, then use a critic agent to score it and guide revision.

AI Agents in Action

A rubric is a structured set of criteria used to specify or evaluate the quality of an agent profile or response.

How it is used
Guides profile and prompt evaluation when accuracy alone cannot capture use-case-specific quality.
How deep it goes
Details objectives, criteria, scales, descriptions, scoring, and automated evaluation, but does not specify a universal rubric.
Examples
Scores recommendations by genre, subject, and format using a one-to-five alignment scale.
What you can do after
Apply it via Prompt flow to score recommendations automatically or establish a manual evaluation baseline.

Reinforcement Learning from Human Feedback

A rubric is a structured set of weighted evaluation criteria for judging the quality of a response to a specific task or prompt.

How it is used
Uses prompt-specific criteria as rewards for improving multiple generated answers through reinforcement learning.
How deep it goes
Defines hard rules and principles, demonstrates them on a prompt, and specifies a weighted configuration schema.
Examples
Uses a museum exhibit request requiring five culturally and historically distinct artifacts with significance, mystery, and engaging presentation.
What you can do after
Apply it via reinforcement learning to evaluate and improve responses without clearly verifiable answers.
