Prerequisites — API Key

Before generating, check if the environment variable EVOLINK_API_KEY is set:

Windows: echo %EVOLINK_API_KEY%
Unix: echo $EVOLINK_API_KEY
If it is empty or not set, ask the user to provide their Evolink API Key.
If the user does not have a key, tell them to register at: https://evolink.ai/signup , then go to https://evolink.ai/dashboard/keys to create an API Key.
Once the user provides the key, save it as a variable in your context for use in subsequent steps. Do NOT use set or export — they will not persist across Bash calls.

Instructions

The user wants to generate an image. If the user did not provide a prompt, ask them first before proceeding.

Extract the following from their request:

prompt: The image description (required — must ask if missing, max 2000 characters)
size: Image aspect ratio (optional, default "1:1"). Options: "1:1", "2:3", "3:2", "3:4", "4:3", "9:16", "16:9", "1:2", "2:1", or custom "WxH" (376-1536px)
seed: Random seed for reproducibility (optional, range: 1-2147483647)
nsfw_check: Enable stricter NSFW content filtering (optional, default false). Ask the user if they want to enable it.
