What it does

Anthropic Art is an agent skill from HalfAI1102/anthropic-art. Generate full-background editorial illustrations in Anthropic's hand-drawn visual language: warm or muted opaque color fields, irregular ivory carrier shapes, and bold black gestural linework. Use when the user asks for an Anthropic-style, Claude-style, hand-drawn AI editorial, newsroom, blog hero, social card, or conceptual illustration, especially when they explicitly require a colored background rather than a transparent icon.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including reference files and assets (for example `agents/openai.yaml` and `references/style-spec.md`).

It sits in Media & Creative, covering Social media graphics. The repository describes itself as: Generate full-background Anthropic-style editorial illustrations with verified palette and hand-drawn visual rules.

When your agent uses it

  • The user asks for an Anthropic-style
  • Hand-drawn AI editorial
  • Conceptual illustration
  • Especially when they explicitly require a colored background rather than a transparent icon

Example prompts

  • “/anthropic-art”

Workflow steps

8 steps, taken from the first numbered list in SKILL.md.

  1. Extract the subject, intended use, aspect ratio, and any exact text. Default to a square editorial card when the user does not specify…
  2. Treat supplied images and bundled assets as style references, not edit targets, unless the user explicitly asks to alter one.
  3. Select one full-bleed opaque background color from the verified palette in the style spec. Never default to transparency or a white outer…
  4. Reduce the concept to one visual metaphor with one dominant object or relationship. Prefer symbolic clarity over a busy literal scene.
  5. Build a structured prompt using the prompt contract below.
  6. Use the built-in image generation tool. Include the smallest useful set of bundled references, normally all three for a new topic.
  7. Inspect the result. Reject or revise when the outer canvas is transparent, white, photographic, glossy, finely vectorized, text-heavy, or…
  8. Iterate with one targeted correction. Save project-bound final images in the workspace and report the final path and prompt.

What it can do on your machine

Read from SKILL.md and the folder at commit feef1e9. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Anthropic Art loads about 1.1k tokens when it runs, and up to ~2.2k if it reads all its reference files. Until then it costs about 112 tokens; SKILL.md has 377 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~112
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 377 words (~1,117 tokens).

“Create a new bitmap illustration from the user's topic. Preserve the visual system, not the literal objects in the references.”
