Why this needs a proper prompt

Grading 30+ essays with meaningful feedback takes 15-20 hours. Most teachers resort to generic comments because individual feedback at scale is unsustainable.

Why Claude for this

Three reasons this actually lands.

The prompt, the codes, the fit. Each one on its own is a nice-to-have. Together, they change the workflow.

The prompt is the product.

One tested prompt, copy-paste ready. Rules baked in, placeholders marked, tone locked down. No prompt-engineering trial runs, no back-and-forth.

Codes that stack.

Prefix with PERSONA, TONE:, REFINE for compound effects. Each code is a documented technique, not a magic word.

Built for the role.

Tuned for education workflows. Not a generic template, and not another "you are a helpful assistant" hack.

Without the pattern vs with it.

What the day looks like when you keep winging the prompt, and what it looks like when you stop.

The prompt
Without it

Generic prompt. Claude writes something that could be about anyone, in any industry, from anywhere. Sounds like a template because it is one.

With it

The CLSkills prompt with placeholders for your context. Claude writes it like a specialist who actually knows the work. Publishable after one edit pass.

The workflow
Without it

You paste, Claude answers, you rewrite, you paste again. Ten minutes of back-and-forth per output. Three hours across a batch of five.

With it

Prompt loaded once. You feed the specifics, Claude returns the finished output. Two minutes per, twenty across five. Same tone, same structure, every time.

The result
Without it

Middle-of-the-road copy that reads AI-flavoured. Recipients notice. Response rates stay low. You end up rewriting most of it anyway.

With it

Rubric-aligned grading with specific, actionable feedback that students can actually use to improve. Quotes their own words to show you read carefully. Cuts grading time by 60%.

The prompt

Copy this, replace the placeholders, ship.

Help me grade this student essay.

Assignment: [WHAT WAS THE PROMPT]
Grade level: [GRADE]
Rubric criteria:
- [CRITERION 1]: [DESCRIPTION + POINT VALUE]
- [CRITERION 2]: [DESCRIPTION + POINT VALUE]
- [CRITERION 3]: [DESCRIPTION + POINT VALUE]

Student essay:
[PASTE ESSAY]

Provide:
1. **Score**: Points for each rubric criterion with brief justification
2. **Strengths** (2-3): Specific things the student did well (quote their words)
3. **Areas for growth** (2-3): Specific, actionable feedback (not "needs improvement")
4. **One next step**: The single most important thing this student should focus on
5. **Margin notes**: 3-5 inline comments I can paste at specific spots in their essay

Tone: Encouraging but honest. This is feedback for learning, not just evaluation.
Be specific — "Your thesis on line 2 makes a clear claim" not "Good thesis."

Replace the [BRACKETED] placeholders with your context.

Codes that help

Stack these prefixes for compound gains.

Prepend one or more of these to the prompt above. Each code is documented on its own page with before and after examples.
