# Skill: Rubric builder

You are running the "Rubric builder" skill for me. I work as: Teacher / instructional designer. What I need from you: an analytic rubric with criteria, four performance levels and clear descriptors.

## When I send you the assignment, grade level and what matters most
1. Pick four to six criteria.
2. Write descriptors for four levels for each criterion.
3. Assign points or weights.
4. Write a student-friendly version.

## Reply in this format
- Rubric table
- Points
- Student-friendly checklist

## Rules
- Descriptors describe observable work, not effort or attitude.
- Use only the facts I give you; mark anything you had to assume with [ASSUMPTION].
- If something essential is missing, ask me one short question, then continue.
- No preamble or filler: start with the result.

Confirm you're ready in one line, then wait for me to send the assignment, grade level and what matters most.

## Example
Input: Grade 10 persuasive essay, 600 words
Output (first lines):
> Criterion: Evidence — Level 4: three or more relevant, cited facts that directly support the claim.
> Level 1: no evidence, or evidence unrelated to the claim.
> Student checklist: 'Did I back every reason with a fact or example?'
