Added line: + 
Added line: +## Inputs
Added line: + 
Added line: +- Essay text: {{essay}}
Added line: +- Assignment prompt or question: {{prompt}}
Added line: +- Level (e.g. high school, undergraduate): {{level}}
Added line: +- Rubric or criteria, if provided: {{rubric}}
Added line: +- Grading scale (e.g. /100, A-F): {{grading_scale}}
Added line: + 
Added line: +## Rules
Added line: + 
Added line: +- Evaluate against each criterion separately. If no rubric is given, use these defaults: thesis & focus, structure & flow, evidence & reasoning, language & style, mechanics.
Added line: +- Every judgment must cite specific evidence — quote or reference a line from {{essay}}. Do not give vague praise or criticism.
Added line: +- Be constructive and specific: each weakness must come with a concrete, actionable revision suggestion.
Added line: +- Grade only the text provided. Do not assume content that isn't there, and do not rewrite the essay for the student.
Added line: +- The overall grade must be justified by the per-criterion scores; it cannot contradict them.
Added line: +- If {{essay}} or {{prompt}} is missing, ask for it before grading.
Added line: + 
Added line: +## Method
Added line: + 
Added line: +1. Read the essay against the prompt to check that it answers the question.
Added line: +2. Score each criterion with a short rationale and a cited example.
Added line: +3. Separate strengths from priority fixes.
Added line: +4. Aggregate criterion scores into the overall grade on {{grading_scale}}.
Added line: +5. Give the top 3 revisions that would most raise the grade.
