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.

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 | $0.00102 | $0.01913 |
| Opus 5 | $0.00051 | $0.00957 |
| Sonnet 5 | $0.00020 | $0.00383 |
| Haiku 4.5 | $0.00010 | $0.00191 |
Grade A, and why
canva-classroom-helper 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 11d 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 — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Canva Classroom Helper — Lesson Plan to Deck
Transform a lesson plan into a clear, teachable presentation: learning goals on screen, logical flow, and slide-by-speaker-notes so the teacher can run the class from one deck.
Workflow
-
Get the lesson plan source (always do this first — no substitute checklist)
- Do not open with a generic two-part prompt (e.g. “paste the plan” and then “describe the topic and key points”). The lesson plan already carries topic and key points; asking twice is redundant and skips this step’s real work (text vs Canva link vs search).
- If the user has not yet given a source, ask one short question that matches this step only, for example: Paste your full lesson plan here, or give a Canva design link or design ID, or the exact title to search in Canva; if the plan is in a file, paste the contents or give a path you can read. Then proceed along the branch below.
- If the user provides the lesson plan as text in chat, use that as the full source
- If the user provides a Canva design ID directly (the identifier from a design URL—typically starts with
D, e.g.DABcd1234ef), use that value asdesign_idwithCanva:start-editing-transactionto read its text content (same as reading from a link, without URL parsing) - If the user provides a Canva design link (e.g.,
https://www.canva.com/design/DAG.../...), extract the design ID from the path and useCanva:start-editing-transactionto read its text content - If the user references a Canva doc or design by name, use
Canva:search-designsto find it, thenCanva:start-editing-transactionto read its contents
-
List available brand kits
- Call
Canva:list-brand-kitsto retrieve the user's brand kits - If only one brand kit exists, use it automatically without asking
- If multiple brand kits exist, present the options and ask the user to select one (school or district brand, if relevant)
- Call
-
Generate the presentation
- Call
Canva:generate-designwith:design_type: "presentation"brand_kit_id: the selected brand kit IDquery: follow the Lesson plan → deck query format below (always a multi-slide deck—see opening lines of that format)
- Show the generated candidates (thumbnails/previews as returned) to the user
- Call
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.
