MATLAB Grader Assessment Item Generator

Generate complete MATLAB Grader assessment item sets in the current agent session. Each assessment item produces a subfolder with native artifact files (description, solution, template, tests) ready to paste into MATLAB Grader. Function assessment items also include function_call.m for MATLAB Grader's "Code to call your function" area. An optional QTI 3 interchange package can be created for portability and sharing.

Terminology note: use "assessment item" in user-facing text. "Problem" may still appear only in legacy compatibility identifiers or when explaining older MATLAB Grader terminology.

Input

The user may have provided a learning objective in their request. If they did not, collect it in Step 1.

Reference Files

Before generating any artifacts, read the appropriate reference files from the references/ directory alongside this skill:

references/assessment-item-types.md — assessment item type definitions, class assessments, output structure
references/assessment-research.md — research-informed formative and summative assessment method
references/options-prompt.md — how to generate assessment item options
references/description-prompt.md — how to generate descriptions (by assessment item type)
references/solution-prompt.md — how to generate solutions (by assessment item type)
references/template-prompt.md — how to generate templates (by assessment item type)
references/function-call-prompt.md — how to generate the student call block for Function assessment items
references/tests-prompt.md — how to generate test cases (by assessment item type)
references/qti3-prompt.md — how to generate optional QTI 3 item and manifest files

Read references/assessment-item-types.md and references/assessment-research.md now to load the type definitions and assessment method.

Pipeline Overview

Step 1: Collect inputs (objective, assessment item type, class assessment if applicable, assessment purpose, output format)
Step 2: Generate 4 assessment item options (varied difficulty)
Step 3: User selects which assessment items to develop
Step 4: For each selected assessment item, generate artifacts sequentially
Step 5: Write files to output subfolders and optional QTI 3 package

Step 1: Collect Inputs

If the user provided a learning objective, confirm it. Otherwise, ask for one.

Collect the following one at a time:

1a. Learning Objective

If the user has not already provided one, ask: "What is the learning objective for these MATLAB Grader assessment items?"

1b. Assessment Item Type

Ask the user to choose an assessment item type:

Script — student submits a .m script; assessed by workspace variables
Function — student submits a .m function; assessed by input/output values
Class — student submits a classdef .m file; assessed via instantiation
Object usage — student submits a .m script that uses a provided class

1c. Class Assessment (only if assessment item type is Class)

If the user chose "Class", ask which aspect to assess:

Constructor - property assignment (blank: obj.prop = arg lines)
Constructor - computed property (blank: derived property computation)
Instance method (blank: method body)
Constant property (blank: value in properties (Constant) block)
Operator overloading (blank: overloaded operator method body)

1d. Number of Options

Ask: "How many assessment item options should I generate? (default: 4)" Accept 2-6. Default to 4 if the user just presses enter or says "default".

1e. Output Directory

Ask: "Where should I write the assessment item folders? (default: current directory)" Default to the current working directory. The user can specify a path.

1f. Assessment Purpose

Ask: "Is this assessment primarily formative, summative, or both? (default: summative)" Default to:

Formative if the user says practice, feedback, homework draft, tutoring, self-check, revision, lab prep, or low-stakes.
Summative if the user says exam, grade, final submission, high-stakes, or does not specify.
Both if the user explicitly wants practice and grading reuse.

Use references/assessment-research.md to apply the correct design rules:

Formative: smaller scope, self-checks, diagnostic test names, and feedback-oriented evidence.
Summative: objective-aligned independent tests, randomized hardcoding detection, edge cases, and minimal answer-revealing hints.
Both: formative self-checks plus summative-grade tests.

1g. Optional QTI 3 Export

Ask: "Should I also create QTI 3 interchange files for portability? (default: no)" Default to no unless the user asks for QTI, portability, standards-based assessment items, interchange files, import/export payloads, or sharing between instructional designers.

If enabled, tell the user: "I will create the normal MATLAB Grader files plus a QTI 3 package. The QTI files preserve the prompt, template, function call block when applicable, solution, tests, and metadata for interchange; they do not make a generic QTI player execute MATLAB grading logic."

Step 2: Generate Assessment Item Options

Read references/options-prompt.md to construct the prompt.

Build the system prompt by:

Starting with the base system prompt from the reference
Replacing {NUM_OPTIONS} with the user's choice
Appending the assessment-item-type-specific note (Class, Function, Object usage, or nothing for Script)

Build the user message with the learning objective and assessment item type. Use the assessment purpose to vary options:

Formative options should be short, diagnosable, and suitable for revision.
Summative options should measure a clear objective with reproducible evidence and enough complexity to distinguish levels of mastery.
Both should be usable for practice first and grading later.

You ARE the AI generating these options. Do not make an API call. Instead, directly generate the JSON array of assessment item options yourself, following the system prompt instructions exactly.

Generate exactly {NUM_OPTIONS} assessment item options as a JSON array. Each must have:

id (1-based integer)
title (descriptive assessment item name)
difficulty ("Easy", "Medium", or "Hard" — spread across options)
concept_focus (the MATLAB concept being tested)
brief_description (1-2 sentence summary)
suggested_variable (the primary variable/class name)
assessment_item_type (must match the user's selected type)
assessment_purpose ("Formative", "Summative", or "Both")

Present the options to the user in a readable table format:

| # | Title | Difficulty | Concept Focus | Description |
|---|---|---|---|---|

Step 3: User Selects Assessment Items

Ask the user: "Which assessment items would you like me to develop? Enter the numbers separated by commas (e.g., 1,3,4), or 'all' for all of them."

Parse the selection into a list of assessment item IDs.

Step 4: Generate Artifacts for Each Selected Assessment Item

For each selected assessment item, generate artifacts sequentially (each builds on the previous). Tell the user which assessment item you're working on: "Generating artifacts for Assessment Item N: {title}..."

4a. Description

Read references/description-prompt.md. Select the correct branch for the assessment item type. Construct the system prompt by filling in {TITLE}, {DIFFICULTY}, {OBJECTIVE}, {ASSESSMENT_ITEM_TYPE}, {ASSESSMENT_PURPOSE}, and for Class assessment items: {CLASS_NAME}, {ASSESSMENT_CONTEXT}, and the assessment-specific extra rules. For Object usage: {OUTPUT_VAR}. Placeholder definitions used across the reference prompts: {ASSESSMENT_CONTEXT} is a one-sentence restatement of the class aspect selected in Step 1c; {CLASS_ASSESSMENT} is that Step 1c option label verbatim.

Generate the description following the prompt instructions exactly. The output must be plain text — no markdown headers, no bold/italic markers.

4b. Solution

Read references/solution-prompt.md. Select the correct branch for the assessment item type. Fill in {TITLE}, {DIFFICULTY}, {OBJECTIVE}, {SUGGESTED_VARIABLE}. For Function: compute {SNAKE_TITLE} from the assessment item title (lowercase, spaces to underscores, strip non-alphanumeric). For Class: {CLASS_NAME}. For Object usage: {OUTPUT_VAR}.

Generate the solution following the prompt instructions exactly. The output must be pure MATLAB code — no markdown fences, no explanation text.

4c. Template

Read references/template-prompt.md. Select the correct branch for the assessment item type. The template prompt REQUIRES the solution from step 4b as context. For Class: select the correct blank rule based on the class assessment type. For Object usage: extract only the student script portion.

Generate the template following the prompt instructions exactly. The output must be pure MATLAB code with % YOUR CODE HERE blanks.

4d. Function Call (only if assessment item type is Function)

Read references/function-call-prompt.md.

Generate function_call.m, the student-facing pre-submit run block used in MATLAB Grader's "Code to call your function" area. Use the required function name and representative sample inputs from the generated solution. The output must be pure MATLAB code: comments plus a simple call that assigns the function output to the primary output variable. Do not include grading assertions, randomized hidden tests, or assessment logic.

4e. Tests

Read references/tests-prompt.md. Select the correct branch for the assessment item type. The tests prompt REQUIRES the solution from step 4b as context. Always include the shared quality rules. Select the correct test order based on assessment item type and class assessment. Apply the assessment-purpose rules from references/assessment-research.md:

Formative tests should be diagnostic and interpretable.
Summative tests should be independent, objective-aligned, randomized, and robust against hardcoding.
Both should include a basic correctness test plus summative-grade edge and transfer tests.

Generate the tests following the prompt instructions exactly. The output must be pure MATLAB code with %% Test N: section headers and assessVariableEqual calls.

4f. QTI 3 Item (only if QTI export is enabled)

Read references/qti3-prompt.md.

Generate one QTI 3 item XML document and one QTI 3 manifest for each selected assessment item after the description, solution, template, optional function call, and tests exist. Use those generated artifacts as source content.

QTI 3 export intent:

Support portability, review, and sharing of self-describing assessment items.
Preserve enough MATLAB Grader-specific content for a future MATLAB Grader importer or agent workflow to reconstruct the native assessment item folder.
Do not claim that a generic QTI runtime can execute MATLAB code or MATLAB Grader tests.

Required source fields:

{TITLE}, {SNAKE_TITLE}, {DIFFICULTY}, {OBJECTIVE}, {ASSESSMENT_ITEM_TYPE}
{ASSESSMENT_PURPOSE}
{CLASS_ASSESSMENT} if applicable
{DESCRIPTION}, {TEMPLATE}, {SOLUTION}, {TESTS}
{FUNCTION_CALL} if assessment item type is Function
{SUPPORTING_CLASS} if object usage

Generate the QTI item XML following the reference exactly. The output must be XML only: no markdown fences and no explan

## Step 4: Generate Artifacts for Each Selected Assessment Item

For each selected assessment item, generate artifacts **sequentially** (each builds on the previous).
Tell the user which assessment item you're working on: "Generating artifacts for Assessment Item N: {title}..."

### 4a. Description

Read `references/description-prompt.md`. Select the correct branch for the assessment item type.
Construct the system prompt by filling in {TITLE}, {DIFFICULTY}, {OBJECTIVE}, {ASSESSMENT_ITEM_TYPE},
{ASSESSMENT_PURPOSE}, and for Class assessment items: {CLASS_NAME}, {ASSESSMENT_CONTEXT}, and the assessment-specific extra rules.
For Object usage: {OUTPUT_VAR}.
Placeholder definitions used across the reference prompts: {ASSESSMENT_CONTEXT} is a
one-sentence restatement of the class aspect selected in Step 1c; {CLASS_ASSESSMENT}
is that Step 1c option label verbatim.

Generate the description following the prompt instructions exactly.
The output must be plain text — no markdown headers, no bold/italic markers.

### 4b. Solution

Read `references/solution-prompt.md`. Select the correct branch for the assessment item type.
Fill in {TITLE}, {DIFFICULTY}, {OBJECTIVE}, {SUGGESTED_VARIABLE}.
For Function: compute {SNAKE_TITLE} from the assessment item title (lowercase, spaces to underscores, strip non-alphanumeric).
For Class: {CLASS_NAME}.
For Object usage: {OUTPUT_VAR}.

Generate the solution following the prompt instructions exactly.
The output must be pure MATLAB code — no markdown fences, no explanation text.

### 4c. Template

Read `references/template-prompt.md`. Select the correct branch for the assessment item type.
The template prompt REQUIRES the solution from step 4b as context.
For Class: select the correct blank rule based on the class assessment type.
For Object usage: extract only the student script portion.

Generate the template following the prompt instructions exactly.
The output must be pure MATLAB code with `% YOUR CODE HERE` blanks.

### 4d. Function Call (only if assessment item type is Function)

Read `references/function-call-prompt.md`.

Generate `function_call.m`, the student-facing pre-submit run block used in MATLAB Grader's
"Code to call your function" area. Use the required function name and representative sample
inputs from the generated solution. The output must be pure MATLAB code: comments plus a simple
call that assigns the function output to the primary output variable. Do not include grading
assertions, randomized hidden tests, or assessment logic.

### 4e. Tests

Read `references/tests-prompt.md`. Select the correct branch for the assessment item type.
The tests prompt REQUIRES the solution from step 4b as context.
Always include the shared quality rules.
Select the correct test order based on assessment item type and class assessment.
Apply the assessment-purpose rules from `references/assessment-research.md`:
- Formative tests should be diagnostic and interpretable.
- Summative tests should be independent, objective-aligned, randomized, and robust
against hardcoding.
- Both should include a basic correctness test plus summative-grade edge and transfer
tests.

Generate the tests following the prompt instructions exactly.
The output must be pure MATLAB code with `%% Test N:` section headers and `assessVariableEqual` calls.

### 4f. QTI 3 Item (only if QTI export is enabled)

Read `references/qti3-prompt.md`.

Generate one QTI 3 item XML document and one QTI 3 manifest for each selected assessment item after
the description, solution, template, optional function call, and tests exist. Use those generated
artifacts as source content.

QTI 3 export intent:
- Support portability, review, and sharing of self-describing assessment items.
- Preserve enough MATLAB Grader-specific content for a future MATLAB Grader importer or
agent workflow to reconstruct the native assessment item folder.
- Do not claim that a generic QTI runtime can execute MATLAB code or MATLAB Grader tests.

Required source fields:
- `{TITLE}`, `{SNAKE_TITLE}`, `{DIFFICULTY}`, `{OBJECTIVE}`, `{ASSESSMENT_ITEM_TYPE}`
- `{ASSESSMENT_PURPOSE}`
- `{CLASS_ASSESSMENT}` if applicable
- `{DESCRIPTION}`, `{TEMPLATE}`, `{SOLUTION}`, `{TESTS}`
- `{FUNCTION_CALL}` if assessment item type is Function
- `{SUPPORTING_CLASS}` if object usage

Generate the QTI item XML following the reference exactly. The output must be XML only:
no markdown fences and no explan
