canvas-design

canvas-design is a skill for Claude Code, Codex from Prismer-AI/PrismerCloud. It costs 59 tokens per session (2,730 once invoked), scanned A, a copy of canvas-design, MIT.

A skill for creating original static visual artwork as PNG images or PDF documents. It is intended for posters, illustrations, and other designed pieces.

In plain words
What is it for?
Use it to create posters, artwork, and other static designs that need to be delivered as PNG, PDF, or related document files.
Why use it?
It gives the agent a defined process for making a finished visual artifact and delivering it as a file. It also keeps the work original rather than copying another artist.

About the project

Prismer Cloud is an infrastructure layer for AI agents that provides shared learning, compressed context, persistent memory, collaboration, messaging, tasks, identity, and workspaces. It is for agents and the people building or using long-running agent systems that need information and outcomes to persist across sessions. The catalogue entries provide skills, hooks, agents, instructions, and a plugin for using Prismer Cloud.

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 17d 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.

Origin

This is a copy

92% identical to canvas-design — 33 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 158 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Delivering the finished artifact

When this skill finishes producing a .png / .pdf (or .md) artifact, write it into the dispatch artifacts dir and deliver it with cloud deliver <abs-path> — this is the one command for a final artifact: it attaches the file to your current reply (one message = your text + the attachment). Run cloud deliver once per output file. See the office-artifacts delivery contract for the full rules (incl. the hermes --run-id / --conversation-id flags).

Do NOT also run cloud file send on the same file — that posts a separate file-only message, so the artifact gets delivered twice (a split "file message" + "text message"). cloud file send is only for ad-hoc mid-conversation sharing, never for your final deliverable. And cloud file upload is NOT a delivery command at all (it only uploads bytes and returns an uploadId — nothing reaches the user) — always use cloud deliver.

Do NOT hand-build POST /api/im/assets calls or assemble ContentBlock JSON yourself, and do NOT paste local file paths (./output.png), data: URIs, or raw bytes into the reply body — the delivery commands register the asset and surface the image preview / PDF card automatically.

Never claim a file you didn't actually write: only describe an artifact as delivered after cloud deliver exits 0 and prints an assetId.

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.

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.
