image-generation

image-generation is a skill for Claude Code from Galbaz1/video-research-mcp. It costs 45 tokens per session (1,547 once invoked), scanned A, original, MIT.

A guide for improving prompts used to generate images by describing the subject, its surroundings, and the visual style.

In plain words
What is it for?
It is for writing prompts for illustrations, photographs, and other generated images, including choices about lighting, camera, materials, and composition.
Why use it?
It helps turn vague image requests into clearer instructions while preserving the user's original idea and keeping recurring characters consistent.

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-generation 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 25d 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.

Image Generation Prompt Best Practices

This plugin does not bundle an image-generation tool. Discover the active provider, inspect its schema, and confirm spend/attempt limits before requesting images. Provider-specific parameter names such as inputImagePath are not portable.

Verified on 2026-09-29: Google documents gemini-3.1-flash-image for general generation/editing, gemini-3.1-flash-lite-image for inexpensive 1K work, and gemini-3-pro-image for complex design. See official image guidance for exact API, supported references, sizes, and pricing; use the provider available to the session.

Prompt Structure

Enhance every image generation prompt around three core elements:

1. SUBJECT (What)

The main focus of the image.

  • Physical characteristics: textures, materials, colors, scale
  • Actions, poses, expressions if applicable
  • Distinctive features that define the subject

2. CONTEXT (Where/When)

The environment and conditions.

  • Setting, background, spatial relationships (foreground, midground, background)
  • Time of day, weather, atmospheric conditions
  • Mood and emotional tone of the scene

3. STYLE (How)

The visual treatment.

  • Artistic or photographic approach: reference specific artists, movements, or styles
  • Lighting design: direction, quality, color temperature, shadows
  • Camera/lens choices: specify focal length, aperture, and shooting angle when photographic

Core Principles

  • Preserve intent -- Enrich the user's original vision, never override it
  • Preserve constraints -- Describe desired elements positively and retain explicit exclusions using supported instructions or a negative-prompt field
  • Specific over vague -- "golden hour sunlight at 15 degree angle" beats "nice lighting"
  • Natural flow -- Weave elements into a single flowing description, not a bullet list

Enhancement Patterns

Hyper-Specific Details

Add concrete visual details where the user left gaps:
