create-visual-asset

create-visual-asset is a skill for Claude Code, Codex from comfuture/novelist. It costs 62 tokens per session (1,223 once invoked), scanned A, original, MIT.

A guide for creating book covers and illustrations with an available image-generation service. It also keeps the visual style consistent across the novel's images.

In plain words
What is it for?
Use it to plan, generate, refine, and save covers, chapter illustrations, spot illustrations, visual motifs, and image prompts.
Why use it?
A book project may need several related images, and creating them without shared direction can make them look unrelated. This organizes the visual work around the project's existing style and story context.

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

create-visual-asset 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 3d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/invoke_image_provider.py, tests/test_invoke_image_provider.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Create Visual Asset

Overview

Use this skill to create project-bound cover and illustration assets for the novel.

Always preserve visual consistency by reading style/visual-style-guide.md first. Detect the image-generation capabilities available in the current host, then use the matching guide:

  • Codex: references/codex-image-generation.md
  • Claude Code: references/claude-image-generation.md
  • Antigravity CLI: references/antigravity-image-generation.md
  • External API or CLI provider: references/external-image-provider.md

Save final project-bound assets under assets/cover/ or assets/illustrations/; never leave a referenced asset only in a provider's default output location.

Required Context

Read before generating:

  • AGENTS.md
  • project.md
  • style/visual-style-guide.md
  • relevant chapters/*.md, outlines/, plot/, world/, characters/, materials/, and macguffins/ files for the requested asset
  • existing files in assets/cover/ and assets/illustrations/

If style/visual-style-guide.md is incomplete, ask the user for missing visual direction before generating a final asset.

Workflow

1. Identify Asset Type

Classify the request as one of:

  • cover: front cover image for EPUB packaging
  • chapter-illustration: full-width or full-page illustration tied to a chapter
  • spot-illustration: smaller image embedded within a chapter
  • motif: reusable visual symbol, object, or atmospheric plate
  • reference: visual exploration not yet used in the manuscript

Confirm the intended destination and filename slug before saving.

2. Gather Direction

Summarize the likely image in Korean:

  • subject
  • narrative moment or symbolic function
  • setting and time period
  • characters shown or deliberately omitted
  • composition and crop
  • mood, lighting, palette, and texture
  • continuity constraints from source files
  • whether text should be included

Ask for missing direction when it affects the image. For covers, ask about tone, central image, and whether the title/author text should be left out for later typography. Prefer no generated text unless the user explicitly asks for it.

Changes

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.
