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.

What it costs to keep this loaded
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 | $0.00058 | $0.00526 |
| Opus 5 | $0.00029 | $0.00263 |
| Sonnet 5 | $0.00012 | $0.00105 |
| Haiku 4.5 | $0.00006 | $0.00053 |
Grade A, and why
canva-resize-for-all-social-media 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 12d 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.

Canva Resize For Social Media
Overview
Use this skill to take one Canva design and create a multi-platform set of resized variants. Identify the source design, generate the requested social formats, export each version, and present the results in a scan-friendly way.
Preferred Deliverables
- A confirmed source design with the right title and edit context.
- Resized variants for the requested social platforms.
- Direct export links and Canva edit links for each successful output.
Workflow
- Identify the source design from a design ID, Canva URL, design name, or the current conversation context.
- Confirm the source design exists and is accessible before starting any resize work.
- Resize the design into the standard target formats for Facebook post, Facebook story, Instagram post, Instagram story, and LinkedIn post. Run independent resize operations in parallel when the tool flow supports it.
- Continue with the formats that succeed even if one or more resize attempts fail.
- Export each successful resized design as a high-quality PNG and collect the download links.
- Present the finished set grouped by platform, including both the PNG download link and the Canva edit link.
Write Safety
- Keep the original design unchanged and work from resized copies.
- If a name search returns multiple designs, identify the right one before resizing.
- Use exact target dimensions for each platform rather than approximations.
- Report partial failures clearly instead of hiding them behind a generic success message.
Output Conventions
- Lead with a short summary of which formats were created successfully.
- List each platform separately with its dimensions, export link, and edit link.
- Mention when two outputs share the same dimensions, such as Facebook Story and Instagram Story.
- If some formats fail, separate successes from failures so the user can act quickly.
Example Requests
- "Resize this Canva design for Facebook, Instagram, and LinkedIn."
- "Make all the social versions of this campaign graphic."
- "Take my flyer design and export all the social post sizes."
- "Resize this Canva link for every major social format."
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
