Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00141 | $0.06322 |
| Opus 5.5 | $0.00056 | $0.02529 |
| Sonnet 5.5 | $0.00028 | $0.01264 |
| Haiku 4.5 | $0.00014 | $0.00632 |
Grade A, and why
post-quiz scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 360 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Post Quiz
Draft and create a Canvas Quiz with AI-generated (or extracted) questions, anchored to source citations the teacher can verify in seconds. Always a draft. Teacher publishes manually.
This skill never publishes anything. The Canvas Quiz is created with
published: false(enforced server-side by the MCP). Teachers review in Canvas and click Publish themselves when ready. This is a hard policy — don't try to flip the published flag, and don't describe what the skill does as "publishing."
When to use
A teacher wants a Canvas Quiz built from something they have. Common phrasings:
- "Create a quiz on the water cycle from this lesson page"
- "Convert this Word doc / PDF / Google Doc to a Canvas quiz"
- "Make 10 multiple-choice questions about my photosynthesis reading"
- "I have a paper quiz I need to put in Canvas — here it is"
- "Quiz this lesson — 20 questions, no essay"
- "Add the actual quiz object for the assessment page I just made" (compose-with-plan-assessment case)
When NOT to use
- Just a Canvas Page describing an assessment (no actual quiz questions inside) — that's
plan-assessment. Some assessments need BOTH a description page (plan-assessment) AND a graded quiz object (post-quiz) — they compose, see "Linkage with plan-assessment" below. - Wholesale rebuilding an existing Canvas Quiz — prefer editing in place: the MCP has
list_quizzes/get_quizto inspect,update_quizfor settings, andupdate_quiz_question/delete_quiz_question/create_quiz_questionfor question-level edits. On New Quizzes,question_idin the edit/delete tools is the item id fromget_quiz→items[].id. There is nodelete_quiztool — removing a whole quiz is a Canvas-UI action.
Prerequisites
- canvas-mcp installed and configured (v0.5.0+, the New Quizzes release).
- New Quizzes enabled in the target Canvas course (Canvas's default). This skill builds a New Quiz via the
/api/quiz/v1service. Classic Quizzes are no longer supported by these tools. - For Google Docs input: the Claude Drive MCP (already authenticated in the Claude.ai / Claude Desktop session).
- A school config is not required.
list_competenciesis consulted only if the teacher asks for competency-aligned questions.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

post-quiz is a skill published in the GitHub repository awesome-town/canvas-mcp-skills (1 stars, last pushed 1mo ago), licensed MIT. It adds 141 tokens to every session and 6,322 once invoked, about $0.0006 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
