Show HN: A Specialized Grok Prompt Refiner for Vision API

Hi HN,

I’ve been working on a specialized tool designed to optimize the Grok prompt experience: Grok Bikini (grok-bikini.com).

The Engineering Goal: My focus is on the Grok prompt refinement logic. While the Grok Vision API is powerful, standard inputs often fail to capture the high-fidelity nuances required for fashion synthesis. I built a layer that programmatically wraps a simple Grok prompt into a structured, photography-spec instruction set—handling lighting, textures, and lens parameters within the model's latent space.

Experimental Setup: To test this, I automated a multi-lingual TDK system for 19 languages. The goal is to see how different cultural contexts interact with the same Grok prompt engine through a semantic buffer (using /grok-prompt-swimwear paths) to balance high-intent keywords with safety filters.
