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 | $0.00091 | $0.01106 |
| Opus 5 | $0.00046 | $0.00553 |
| Sonnet 5 | $0.00018 | $0.00221 |
| Haiku 4.5 | $0.00009 | $0.00111 |
Grade A, and why
canva-design-feedback 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 9d 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 — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Get Design Feedback
Act as a design reviewer: read the design as it actually appears, then return concrete, prioritised feedback the user can act on. This skill is read-only — it never edits the design. When the user wants the changes made, hand off to canva-edit-design or canva-implement-feedback.
What you can actually read (and the gap to know about)
Canva:get-design-contentreturns text (richtexts) only — good for copy, headings, and wording, but it does NOT include colors, fonts, sizes, or element positions.Canva:get-design-thumbnailgives you the rendered image — this is how you "see" layout, hierarchy, balance, color, and contrast. Always pull this; visual critique depends on it.- Element positions, sizes, and text are reliably available from a read-only editing transaction:
Canva:start-editing-transaction, inspect the returnedrichtexts/fills, thenCanva:cancel-editing-transaction(never commit — you are not changing anything). Use this for layout/spacing/alignment detail. - Colors and fonts are NOT reliably exposed. Tested: the transaction payload often returns only text + position + dimension per element, with no color or font attributes. So treat the thumbnail as the primary source for any color, contrast, or typography judgement, and treat transaction style data as best-effort (use it when present, don't depend on it). Never report a specific hex/font as fact unless the payload actually contained it.
Workflow
Step 1: Resolve the design
Short link → Canva:resolve-shortlink; full URL → extract the ID; raw D... ID → use directly; otherwise ask.
Step 2: Read the design
Canva:get-designfor title and page count.Canva:get-design-thumbnail(and/orCanva:get-design-pages) to see each page.Canva:get-design-contentfor the text.- Optional (typography/color detail): read-only transaction as described above, then cancel it.
Step 3: Evaluate across dimensions
Assess the design against these lenses. Skip any that don't apply to the design type:
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.

canva-design-feedback is a skill published in the GitHub repository canva-sdks/canva-skills (92 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 91 tokens to every session and 1,106 once invoked, about $0.0005 per session on Opus 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 2026-08-30.
