canvas-design

A method for creating original visual artwork as PNG or PDF files by first defining an artistic direction and then expressing it through layout, colour, shapes, images, and space.

In plain words
What is it for?
It is for creating posters, static art, and other visual designs where the result should be mostly visual with only a small amount of text.
Why use it?
It gives visual projects a coherent design idea before the final artwork is made.

Token cost

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.

Security

Grade A, and why

canvas-design 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 2d 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 — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.

These are instructions for creating design philosophies - aesthetic movements that are then EXPRESSED VISUALLY. Output only .md files, .pdf files, and .png files.

Complete this in two steps:

  1. Design Philosophy Creation (.md file)
  2. Express by creating it on a canvas (.pdf file or .png file)

First, undertake this task:

DESIGN PHILOSOPHY CREATION

To begin, create a VISUAL PHILOSOPHY (not layouts or templates) that will be interpreted through:

  • Form, space, color, composition
  • Images, graphics, shapes, patterns
  • Minimal text as visual accent

THE CRITICAL UNDERSTANDING

  • What is received: Some subtle input or instructions by the user that should be taken into account, but used as a foundation; it should not constrain creative freedom.
  • What is created: A design philosophy/aesthetic movement.
  • What happens next: Then, the same version receives the philosophy and EXPRESSES IT VISUALLY - creating artifacts that are 90% visual design, 10% essential text.

Consider this approach:

  • Write a manifesto for an art movement
  • The next phase involves making the artwork

The philosophy must emphasize: Visual expression. Spatial communication. Artistic interpretation. Minimal words.

HOW TO GENERATE A VISUAL PHILOSOPHY

Name the movement (1-2 words): "Brutalist Joy" / "Chromatic Silence" / "Metabolist Dreams"

Articulate the philosophy (4-6 paragraphs - concise but complete):

To capture the VISUAL essence, express how the philosophy manifests through:

  • Space and form
  • Color and material
  • Scale and rhythm
  • Composition and balance
  • Visual hierarchy

CRITICAL GUIDELINES:

  • Avoid redundancy: Each design aspect should be mentioned once. Avoid repeating points about color theory, spatial relationships, or typographic principles unless adding new depth.
  • Emphasize craftsmanship REPEATEDLY: The philosophy MUST stress multiple times that the final work should appear as though it took countless hours to create, was labored over with care, and comes from someone at the absolute top of their field. This framing is essential - repeat phrases like "meticulously crafted," "the product of deep expertise," "painstaking attention," "master-level execution."
  • Leave creative space: Remain specific about the aesthetic direction, but concise enough that the next Claude has room to make interpretive choices also at a extremely high level of craftmanship.

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.

canvas-design is a command published in the GitHub repository hamr0/agentic-toolkit (22 stars, last pushed 3d ago), licensed Apache-2.0. It adds 59 tokens to every session and 2,353 once invoked, about $0.0003 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.
