Test what you built, find what's missing, and ship a better version
Building something is only half the job. The other half is making it better. Today you open your image prompt agent, use it to generate a real prompt, and then turn it into a critic to spot at least three things it could do better. This is the cycle every developer and designer lives by, test, identify, fix, and retest, and you will use it to upgrade your agent from version 1 to version 2.
A vague image prompt gives the AI too much freedom and produces unpredictable results, while a precise one constrains it to produce what you actually had in mind. Precision comes from being specific about the subject, style, mood, lighting, composition, and medium. Order matters too, because image generators read a prompt from top to bottom and give the most weight to what comes first. Every prompt also has two halves, a positive prompt for what you want and a negative prompt for what to leave out, such as blurry, watermark, or distorted faces.
