A test case the skill fixed. Same model, same prompt, with and without the skill.
Prompt
We need an LLM workflow to grade student essays against a 5-criterion rubric. Passing the entire essay and all 5 rubrics in one prompt yields inconsistent scores. How can progressive disclosure or multi-step prompting improve grading accuracy?
