image-authoring is a skill for Claude Code, Codex from kirodotdev/KiroCrew. It costs 45 tokens per session (1,823 once invoked), scanned A, original, Apache-2.0.

A way to create images and diagrams by writing code, including SVG, Pillow, Excalidraw, and Mermaid files. The result stays editable as code.

In plain words
What is it for?
Drawing illustrations, icons, logos, posters, diagrams, and other graphics, including updates to images created earlier.

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

image-authoring 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.

How it starts

The opening of the file, as written. The whole thing — 140 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Image Authoring

Create images by authoring them as code — there is no text-to-image model or image-generation tool in this environment. Use when the user says "generate/create/make an image", "draw", "illustrate", "picture of", "logo", "icon", "poster", "banner", "mascot", "sprite", "texture", "wallpaper", or asks to change/tune an image you made earlier.

HARD RULES

  1. Never look for an image-generation tool. None exists. You ARE the artist — author the image as code and save the file.
  2. Never present this as AI text-to-image generation. It is authored graphics. For photorealism requests, explain the output is stylized (vector / procedural art) and offer the closest achievable style.
  3. Never recreate from scratch when the user gives feedback. Update the brief, then make targeted edits to the existing source.
  4. Always keep the editable source. SVG is its own source; for raster output keep the generating script/HTML next to the image so it can be edited and re-run.

Workflow

1. Brief — summarize the context

Before authoring, compose a short brief from EVERYTHING relevant in the conversation (earlier descriptions, project context, corrections), not just the last message: subject, style, palette, mood, 2–3 signature details, size/aspect, output format. Echo it in one line — "Authoring: " — so the user can correct course before you draw.

2. Choose the technique

Request Technique
Illustration, character, logo, icon, scene, stylized art SVG authoring (primary)
Poster, banner, card, meme, text-heavy composition HTML/CSS → Playwright screenshot
Texture, gradient art, pixel art, noise, filters, compositing Python + Pillow (raster)
Raster copy of an SVG (user needs .png) Convert: rsvg-convert → inkscape → magick → Playwright screenshot
Flowchart, architecture, data chart Prefer mermaid / widgets; else SVG or Pillow
Hand-drawn / whiteboard-style diagram, sketch aesthetic Excalidraw scene — see below

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.
