gpt-image-gen skillA

gpt-image-gen is agent-read markdown (skill) from code-yeongyu/senpi: MUST read before generating images. Detailed prompt-crafting guide for gpt-image models, covering tool routing (native image_generation server tool vs the generate_image tool), prompt structure from subject to background, verbatim text rendering, anti-patterns, and the revised_prompt feedback loop for iteration..

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.

How to install

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
