Optimizes image generation prompts using Subject-Context-Style structure. Use this skill when generating images, creating illustrations, photos, visual assets, editing images, or crafting prompts for any image generation model.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Image Generation Prompt Best Practices ## Prompt Structure Enhance every image generation prompt around three core elements: ### 1. SUBJECT (What) - Physical characteristics: textures, materials, colors, scale - Actions, poses, expressions if applicable - Distinctive features that define the subject ### 2. CONTEXT (Where/When) - Setting, background, spatial relationships (foreground, midground, background) - Time of day, weather, atmospheric conditions - Mood and emotional tone of the scene ### 3. STYLE (How) - Artistic or photographic approach: reference specific artists, movements, or styles - Camera/lens choices: specify focal length, aperture, and shooting angle when photographic ## Core Principles - **Preserve intent** — Add visual details (lighting, texture, composition) only in areas the user left unspecified; keep all user-specified elements unchanged - **Positive descriptions only** — Describe what should be present; rephrase any exclusion as an inclusion - **Specific over vague** — "golden hour sunlight at 15° angle" beats "nice lighting" - **Natural flow** — Weave elements into a single flowing description, not a bullet list ## Output Format …

How to install
mdr add shinpr/mcp-image/image-generation@sha256:43acbbc6210712daThe line at the top of this page pins the label git:20260330.4cbdc1b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
