econnx/student-skills

A Claude Code plugin with five skills for students:
| Skill | What it does |
| essay-check | Grades your essay draft against the course rubric like a strict teacher: score per criterion, quotes from your text, the 3 fixes that add the most points. It does not rewrite the essay for you. |
| solution-check | Checks your own homework solution step by step from photos of your notebook, a PDF or text: finds the first wrong step in each task, says what kind of mistake it is (sign, chain rule, missing endpoint check…) and gives a hint instead of a ready answer. Every verdict is double-checked numerically. |
| doc-privacy | Checks a .docx, .xlsx, .pptx or .pdf before you submit it: your name in the metadata, editing time, comments, tracked changes, hidden or white text, invisible zero-width characters. Can make a clean copy. |
| exam-prep | Turns your lecture notes or slides into a practice exam with an answer key, then quizzes you one question at a time and lists your weak spots. |
| cheatsheet | Builds the one A4 page you may bring to a test from the syllabus and your notes: two columns, every formula with its conditions, ready to print or copy by hand. It follows your course's rules for the sheet. |

"Check my essay essay.docx against the rubric in criteria.pdf"
"Here are photos of my calculus homework and the task PDF. Where did I go wrong?"
"Does report.docx have any hidden data before I send it?"
"Make me a practice exam from the slides in lectures/"
"We can bring one A4 sheet to the calculus test. Make it from syllabus.pdf"
