Canvas Quiz

Work a Canvas-native quiz (Classic Quizzes) — find it, open the attempt, read every question, save it to output/, fill the answers, and stop short of submitting. Use whenever Max points at a Canvas quiz, asks about a "syllabus quiz" or a quiz he still has to take, asks what a quiz is asking, or when a Canvas assignment turns out to have submission_types ["online_quiz"] with a quiz_id. Not for MyOpenMath quizzes — those are external_tool assignments and belong to the myopenmath skill.

Canvas quizzes

Drives a Canvas Classic Quiz end to end with the Claude in Chrome tools. The full runbook — every trap, with the fix — is tooling/CANVAS_QUIZZES.md. Read it before the first interaction; what follows is the shape of the job.

The page helper is tooling/canvas-quiz.js, the CLI is scripts/canvas-quiz.mjs.

Which runbook

Check the assignment's submission_types:

["online_quiz"] + a quiz_id → this skill.
["external_tool"] at myopenmath.com → myopenmath skill. Different machinery entirely (LTI iframe, MathQuill, per-question submits).

Ask first

Three separate asks, and they do not imply each other:

Opening the attempt — the one people underestimate. On a 1-attempt or timed quiz this is the irreversible step, not the submit. Always check info first and quote the numbers when you ask.
Typing answers.
Submitting. Never on your own initiative.

Never enter credentials anywhere.

Steps

Find it — node scripts/canvas-quiz.mjs list <courseId>. The /quizzes API index is disabled on many courses; this walks assignments instead, which always works.
Pre-flight — node scripts/canvas-quiz.mjs info <courseId> <quizId> and attempts <courseId> <quizId>. Read allowed_attempts and time_limit out loud before doing anything. A timed quiz means the clock runs while you think — plan the answers before opening it.
Open the attempt — a real click on Take the Quiz. A GET on /take silently re-renders the landing page and starts nothing; it looks broken but isn't. Confirm #submit_quiz_form exists and the .display_question count matches question_count.
Read and save, before answering. Paste tooling/canvas-quiz.js, call __QDUMP(). javascript_tool truncates around 1 KB — chunk via JSON.stringify(__QDUMP()).match(/[\s\S]{1,900}/g). Then node scripts/canvas-quiz.mjs render <dump.json> output/<name>.md.
Fill — __QSET(n, choice): index or text for choice questions, an array for multiple-answers, a string for text, an object for blanks/matching.
Verify — __QVERIFY() re-reads the DOM, and __QSTATE() shows the Quiz saved at ... stamp. Screenshot: the sidebar checkmarks confirm the whole quiz at a glance. A save stamp is what proves the server has it.
Stop. Leave the attempt open, answered, and saved for Max to submit — unless he says otherwise in the moment.

The four that actually cost something

Opening is the irreversible step, not submitting, when attempts are limited.
GET /take starts nothing. Click the button.
Multiple-answers checkboxes all have value="1" — match by text or index. __QSET clears the group first, so an array is the final state.
A DOM-only answer is not saved. Check the Quiz saved at stamp before walking away or reloading.

Answering from a source document

Syllabus and policy quizzes should trace to the source. Put the trace in each question's rationale field — render prints it as a > Why: line, which makes the saved markdown reviewable instead of a bare answer key. Call out real judgment calls explicitly rather than letting them pass as quotes.
