media-prompt-craft skillA

media-prompt-craft is agent-read markdown (skill) from lukaskellerstein/claude-my-marketplace: Craft effective prompts for AI image/video generation and search queries for stock photo services. Translates design direction and styleguide choices into specific, style-consistent prompts. Use when the user asks to "find images for my site", "generate a hero image", "what kind of images should I use", "create image prompts for my project", "write prompts for image generation", "Unsplash query for...", or when building a media asset list for a design project. Works with any styleguide and deleg.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
