Individual skill

rubric-builder

Builds grading rubrics - analytic, holistic, or single-point - with criteria traced to learning objectives, 3-5 performance levels, observable behavior in every cell, and defensible weighting. Use when someone asks "make a rubric for this essay", "how should I grade this project", "turn these objectives into scoring criteria", or "my rubric feels vague, fix it". Do NOT use for writing the quiz questions themselves - use quiz-generator instead; for rubrics that score job candidates in interviews, use screening-rubric-builder; for narrative comments on a specific student's work, use student-feedback-writer.

# Rubric Builder

A rubric does two jobs: it tells students exactly what mastery looks like before they begin, and it gives teachers a consistent, defensible standard when scoring. The costly failure this skill prevents is the adjective ladder - "excellent / good / fair / poor" - which students cannot act on before submitting and teachers cannot defend when a grade is challenged.

## Operating procedure

### Step 1: Gather inputs

1. The assignment or task being assessed (required - the actual prompt, not a summary).
2. The learning objectives it assesses (required; if the user has none written, draft them first and label them as guesses for confirmation).
3. Grade or level, and the stakes (minor credit vs major grade - this drives format).
4. Point total, if the gradebook requires one (default: 100).
5. Whether a student-facing version is needed (default: offer one).
