Stop re-typing your best prompts. Upload them once.
Twenty Claude skills, each one a teaching workflow I run on my own courses: triaging a stack, cheating my own assignment before students do, resurrecting a dead lecture, stress-testing a syllabus.
Download the zip. Upload it to Claude. Type one sentence and the whole procedure runs, same format every time, with the privacy rules built in.

The Gem orphan
You built a Gem or a custom GPT that did one job well, and the platform is retiring it. A skill is the same idea with a file you own. Upload it once and it stays yours.
The prompt re-typer
You have a good prompt saved somewhere and you paste it in by hand every Sunday. A skill is that prompt with the paste step removed and the output format locked.
The never-started
You have read a hundred posts about teaching with AI and run none of them. Each skill here does one job in one sitting. Pick one and type the sentence on the card.
Who built these
I am a professor of entrepreneurship at John Carroll University and the Founding Director of the Bill & Sue Donnelly School of Leadership and Social Innovation. I cofounded the Experiential Entrepreneurship Curriculum, used at about 200 colleges. Thousands of teachers read my newsletter, How to Teach With AI.
Every skill here started as a prompt I ran by hand on my own grading, my own assignments, my own lectures. The skill is the version that stopped needing me to remember the steps.
Why a prompt in a note is not enough
A prompt you paste by hand drifts. You trim it when you are tired, the output format changes, and three weeks later you cannot tell which version produced the feedback you liked.
A prompt also forgets the rules. The privacy scrub, the no-grading line, the question it should ask before it starts: those live in your head, and your head is at paper 23 of 40 on a Sunday night.
A skill holds all of that in one file. You type one sentence. The procedure runs the same way every time, and you spend your attention on the judgment calls that are actually yours.
The library
Twenty skills in four groups. Each card names the job and the sentence that starts it. Every zip carries a README with the install steps for Claude.ai, the Claude desktop app, and Claude Code, plus the paste-in fallback for ChatGPT, Gemini, and Copilot.
Grading and feedback
Feedback In My Voice
Paste three or four pieces of feedback you have written. Every draft after that sounds like you, not like a bot.

Open the library to downloadRubric Calibration
Reads your rubric against an A, a B, a C, and a D and reports where the criteria cannot tell them apart.
Type: “Calibrate my rubric.”
Open the library to downloadGrade-Along Partner
You grade one paper and say why. It pre-reads the rest and flags where it predicts you will land. You decide every grade.

Open the library to downloadThe Feedback Audit
After grading, reads everything you wrote and reports what you praised, what you dinged on repeat, and which comments went tired.

Takes the assignment plus the confession and rewrites it so the graded object includes the student's decisions. Learning goal untouched.

Runs your exam question by question and labels each one: answerable by a phone under the desk, or not, with the reason.

Reads a deck outline, cuts it to what earns class time, and moves the rest into a handout it drafts for you.
Type: “Operate on this deck.”
Open the library to downloadReading Guide Builder
Turns an assigned reading into a guide that forces engagement: predictions before, checkpoints during, one argument to attack after.

Five minutes after class: what the plan predicted, what happened, the revision list, and the updated plan.

Open the library to downloadQuestions teachers ask before downloading
What is a skill, in plain terms?
A folder with one instruction file in it. You upload the zip to Claude once. From then on, when you type the trigger sentence, Claude follows the procedure in the file: what to ask you for, what to produce, what format to use, what it is never allowed to do.
Do I need a paid Claude account?
No. Skills upload on the free plan once you switch on code execution under Settings, then Capabilities. The README in every zip also tells you how to run the same workflow in ChatGPT, Gemini, or Copilot by pasting the instructions as your first message.
Why are these free?
Because they fill my newsletter with the exact teachers I write for, and because each one is the lite version of a workflow I sell in full. The README in each zip says what the full version adds. Nothing inside a skill asks you to buy anything.
What about student privacy?
Every skill carries the same rule: names, grades, student IDs, and accommodation details never go into a chat. The skills that touch student work tell you to swap names for Student A, B, C before they continue, and refuse to proceed until you do.
Do the skills grade for me?
No. They sort, flag, draft, predict, and rewrite. Every grade and every judgment stays yours, and the output formats say so out loud.
Can I edit them?
Yes. SKILL.md is a plain text file: change the output format, add your own rubric language, tighten a rule, then re-zip and re-upload.
Twenty jobs. One sentence each.
By Sunday you can have the triage skill sorting your stack, the cheat skill doing your own assignment the way a student would, and the debrief skill waiting for you after Monday's class.
Or the prompt stays in the note, and you keep re-typing it.
