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

content-image 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 9d 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.

Content Image Skill

Important: This Skill Generates Prompts, Not Images

Claude cannot generate images. This skill produces ready-to-paste prompts optimized for AI image generation models. The output is text that the user copies into DALL-E, Midjourney, Stable Diffusion, or another image generation tool.

Every output includes:

  1. The prompt text (optimized for the target model)
  2. Recommended model and settings
  3. Negative prompt (where the model supports it)
  4. Variations to try

When This Skill Activates

  • User asks for an image, illustration, or visual asset
  • User wants to create image prompts or optimize existing prompts
  • User mentions DALL-E, Midjourney, Stable Diffusion, Flux, or other image generation tools
  • User says "generate an image of..." or "I need a visual for..."
  • User wants a hero image, social media graphic, blog illustration, or product shot

Prompt Structure

Every effective image prompt has four components:

1. Subject

What is in the image. Be specific and concrete.

  • Bad: "a person working"
  • Good: "a software developer sitting at a standing desk with dual monitors, writing code, coffee mug nearby"

The subject should be described in enough detail that two different artists would produce recognizably similar images.

2. Style

The visual treatment. Reference a specific style from the style library or describe it explicitly.

  • Bad: "nice looking"
  • Good: "editorial photography, shallow depth of field, natural window light, 35mm lens"

See style-library/ for pre-built style descriptions:

  • style-library/editorial.md -- Clean, professional photography
  • style-library/flat-illustration.md -- Bold, geometric, vector-like
  • style-library/3d-render.md -- Soft lighting, smooth surfaces, product-shot feel
  • style-library/film-still.md -- Cinematic, dramatic, atmospheric

3. Mood / Atmosphere

The emotional tone of the image.

  • Calm, focused, productive
  • Energetic, vibrant, optimistic
  • Dramatic, tense, high-stakes
  • Warm, inviting, approachable
  • Minimal, quiet, contemplative

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.
