shotpilot 是做什么的？
Autonomous image-generation director. Use whenever the user asks to create, generate, render, edit, transform, restyle, translate, repair, or improve an AI image or image prompt. Converts the user's request into a precise canonical JSON image spec, validates it, adapts it to the available image-generation tool/provider, and dispatches generation automatically so the user does not need to copy JSON or prompts. Handles references, identity preservation, products, people, photorealism, illustrations, posters, UI, text-in-image, aspect ratios, camera perspective, and negative constraints.
