Windcraft vs prompt engineering
You can write an ever-longer prompt begging the model to match the last screen. It will try, and it will still guess. Windcraft removes the guessing: the model reads your real values, and a checker confirms it used them.
Prompt engineering encodes your design system in words the model interprets fresh on every generation. Windcraft encodes it in values the model reads — tokens, contracts, patterns over MCP — and verifies the result with a static analyzer. One depends on interpretation; the other on retrieval and a check.
| Aspect | prompt engineering | Windcraft |
|---|---|---|
| How design intent is conveyed | Adjectives in a prompt ("calm", "consistent") | Exact tokens and contracts the model reads |
| Repeatability | Re-interpreted differently each generation | Same values returned every time, deterministically |
| Context cost | Eats tokens; long prompts crowd the window | Values fetched on demand over MCP, not pasted |
| Verification | You hope the prompt worked | Static analyzer confirms the output is on-token |
When prompt engineering is the right call
For a one-off screen or a quick experiment, a good prompt is faster than any setup — you describe what you want and move on. Prompting also handles the things Windcraft does not: tone, copy, and one-off layout intent. Windcraft wins for the measurable design language that must hold identical across many generations.
FAQ
- Can I just write a really detailed prompt?
- You can, and it helps — but words are interpreted, not read. "Use our blue" still leaves the model picking a hex. Windcraft gives it the exact value, so there is nothing left to interpret for the measurable parts of your design.
- Does Windcraft replace prompting?
- No. You still prompt for behavior, copy, and layout intent. Windcraft owns the design values underneath, so your prompts can be about what to build, not a re-description of how it should look.
- Why is reading values better than a longer prompt?
- Longer prompts are still probabilistic and they consume context. Windcraft serves the values deterministically over MCP and checks the result with the analyzer, so consistency does not ride on prompt wording.
