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 | $0.00083 | $0.02052 |
| Opus 5 | $0.00042 | $0.01026 |
| Sonnet 5 | $0.00017 | $0.00410 |
| Haiku 4.5 | $0.00008 | $0.00205 |
Grade A, and why
canva-presentation-time-fitting 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 8d 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 — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Presentation Time-Fitting
Take an existing Canva presentation and align it with a target speaking duration using presenter notes only. Visible on-slide text is read for context and timing, but must not be changed by this skill. The flow is: confirm design + total duration (before cloning), read slide text, divide time across slides, add, replace, or trim speaker notes per slide to match each slot, write notes only back via Canva editing tools.
Primary workflow (time-balanced presenter notes)
Step 1: Collect design and duration (before other Canva tool calls)
- Gather everything you need before calling
Canva:resize-design,Canva:get-design-contentor other editing/content tools:- Design: link (
canva.link), full Canva URL, design ID, or design name (see Step 2 for how each maps todesign_id) - Total speaking time for delivering the deck (e.g.
"15 minutes","45 min","1 hour"). Parse to total seconds (or minutes as a decimal). If the user is vague, confirm the total minutes they want for speaking through the slides (include Q&A in that total only if they say so)
- Design: link (
- If either design or duration is missing, ask and wait before proceeding
Step 2: Resolve the design
- If the user provides a short link (
canva.link), callCanva:resolve-shortlinkto get the design URL - If the user provides a full Canva URL, extract the design ID (
https://www.canva.com/design/{design_id}/...) - If the user provides a design ID directly (typically starts with
D, e.g.DABcd1234ef), use it asdesign_id; do not useCanva:search-designsfor a raw ID - If the user provides a design name (not an ID), use
Canva:search-designs; if multiple matches, ask for clarification - If you still cannot resolve a design, ask for the design ID or link
Step 3: Work on a copy (required)
- Use
Canva:resize-designwith the same dimensions as the source to clone the presentation; do not modify the original
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.
