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 | $0.00063 | $0.01369 |
| Opus 5 | $0.00032 | $0.00685 |
| Sonnet 5 | $0.00013 | $0.00274 |
| Haiku 4.5 | $0.00006 | $0.00137 |
Grade A, and why
canva-resize-for-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
Automatically resize a single Canva design into multiple social media formats.
Overview
This skill enables rapid multi-platform content distribution by taking a single Canva design and creating optimized versions for:
- Facebook post
- Facebook story
- Instagram post
- Instagram story
- LinkedIn post
All resized versions are provided with Canva edit links so users can further edit or download them directly from Canva.
Workflow
Step 1: Identify the Source Design
Determine which Canva design the user wants to resize. This can be provided in three ways:
-
Direct design ID: User provides a design ID (starts with "D")
- Example: "resize design DABcd1234ef for all social media"
- Use the design ID directly with
get-designtool to retrieve design information
-
Direct design URL: User provides a Canva design link
- Example: "resize https://www.canva.com/design/DABcd1234ef/... for all social media"
- Extract the design ID from the URL (the part after
/design/and before the next/or query parameter) - Use the extracted design ID with
get-designtool
-
Search by design name: Use
search-designstool with the design name as the query- Example: "resize my Demo Brand Template: Brix&Hart Flyer design for all social media"
- Use the exact name/phrase the user provides as the search query
- If multiple matches are found, present options and ask the user to select one
-
Current context: If the user just created or edited a design in the conversation, use that design ID
Implementation note: When searching by name, pass the design name directly to search-designs as the query parameter. The tool will find the best match based on the design title.
Step 2: Retrieve Source Design Information
Use the get-design tool with the design ID to:
- Confirm the design exists and is accessible
- Get the design title (for naming resized versions)
- Verify design type compatibility
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.
