# Design Rule Matrix · 设计硬/软判据表

> Use before regenerating an interface. The matrix separates what the machine can enforce from what
> only human taste can judge.

## 1. Brief

| Field | Fill |
|---|---|
| User / audience |  |
| Job to be done |  |
| Emotional target |  |
| Anti-reference |  |
| Must preserve |  |
| Must avoid |  |

## 2. Hard Rules

These are machine-checkable. Put them into lint, tokens, tests, or review scripts where possible.

| Rule | Token / check | Pass condition | Fails block? |
|---|---|---|---|
| Palette source |  |  | yes / no |
| Contrast threshold |  |  | yes / no |
| Type scale |  |  | yes / no |
| Spacing rhythm |  |  | yes / no |
| Component constraints |  |  | yes / no |
| Forbidden AI-slop patterns |  |  | yes / no |

## 3. Soft Criteria

These require human judgment. Do not pretend they are solved by generation.

| Criterion | What good means here | Evidence to inspect | Owner |
|---|---|---|---|
| For whom |  |  |  |
| Distinctiveness |  |  |  |
| Taste / fit |  |  |  |
| Narrative hierarchy |  |  |  |
| Interaction meaning |  |  |  |

## 4. Generation Prompt Gate

Before prompting, write:

- The one user this is for:
- The one generic mean to avoid:
- The hard rules the generator may not violate:
- The soft criteria a human will judge afterward:
- The single fact that will cut the candidate set:

## 5. Decision
