Rubric Builder Skill

A good rubric turns "this feels like a B" into a defensible, repeatable judgment — and tells students exactly how to do better. This skill builds one with observable descriptors at each level.

Working from a brief

Given the assignment and level, build the full rubric anyway, inferring sensible criteria and weighting. Mark anything assumed. Never leave "[describe level]"; write concrete descriptors.

Required Inputs

Ask for (if not already provided):

• The assignment / task being graded and grade or level
• What matters most (the criteria, or let the skill propose them)
• Scale (e.g. 4-level: Exemplary/Proficient/Developing/Beginning) and total points
• Type — analytic (per-criterion) or holistic (single overall judgment)
