Exclusions are design decisions

The model fills every open slot with its most probable content, and exclusions close slots.

When to use

Every image brief, and any text brief where the model keeps adding something you did not ask for. Exclusions are the last slot of the seven-slot brief and the one most often left empty.

The method

Run the brief once without exclusions. Read the output for what arrived uninvited: people, planting, warm fairy lights, a second storey, a glass balustrade. Name each one and forbid it: "no people", "no planting", "no artificial light". Put the exclusions on their own line, not buried in the description. Run again. Keep the exclusions that changed something. Record them with the brief, because each one is a decision about what your building is not.

Watch for this

Some image tools, especially older diffusion pipelines, read the noun in an exclusion as the thing itself: "no trees" can add trees. Many tools therefore give exclusions their own field, often called a negative prompt. Where that field exists, use it: a "no" in the prose asks; the negative-prompt field is the control the tool actually reads. Test how your tool handles a "no" before you trust one.

Try it

Take a brief you have run. Add three exclusions chosen from what the first output added on its own. Run it again and mark what changed. Then remove one exclusion and watch the default return.

Prove it

Name a default the model kept adding until you excluded it by name, and show the before and the after.

How it works

Every slot you leave open, the model fills with its most probable content. Exclusions close slots. That is why they carry design intent: "no glass balustrade" is a decision about material, just as "brick parapet" is. The card is marked EVOLVING because how tools handle negation is changing — image-reasoning models increasingly read "no" the way a person does, while older diffusion pipelines still need a separate negative field. The method works either way.
