11 條工藝原則。.
與品牌無關的工藝規則——可達性、RTL、動效曲線、攝影倫理。技能透過 `od.craft.requires` opt-in，外掛自動繼承相應嚴謹度。
- 01 Accessibility baseline Universal rules for the legal floor of accessibility plus the craft commitments that go beyond it. The active DESIGN.md decides brand appearance; this file decides which rules an artifact has to clear before it ships.
- 02 Animation discipline Universal rules for when motion earns its place in a UI and what numbers constrain it. The active DESIGN.md decides brand-specific motion personality; this file decides whether motion should run at all and at what duration, easing, and accessibility floor.
- 03 Anti-AI-slop rules Concrete, checkable rules that distinguish "designed by a human who has shipped product" from "default LLM output." Several rules below are auto-enforced by the daemon's lint-artifact linter — failing an enforced rule is not a style preference, it is a regression. The rest are guidance for agents and reviewers and are flagged inline as "(guidance, not auto-checked)" so the contract with the linter stays honest.
- 04 Editorial typography hierarchy Extends typography.md + typography-hierarchy.md. Defines hierarchy behavior for editorial surfaces: long-form articles, magazine layouts, digital guides, editorial landing pages, and blog posts.
- 05 Form validation Universal rules for form validation lifecycle, error wiring beyond the accessibility baseline, and the schema-as-contract layer that makes the same validation work on the server and the client. The active DESIGN.md decides how the field looks; this file decides when the field tells the user it's wrong, how the error reaches assistive tech, and where the rule lives.
- 06 Laws of UX Universal cognitive, perceptual, and behavioral heuristics that decide what a UI composes — how many pricing tiers fit on a screen, where a primary action anchors in scanning order, when a progress indicator earns its place, why a settings list needs grouping. The active DESIGN.md decides brand visual language; the existing craft files decide rendering rules (color, typography, motion, states, ARIA, RTL, forms); this file decides composition rules grounded in named research.
- 07 RTL 與雙向文字工藝規則 這條 Open Design 工藝規則定義 RTL 與雙向文字 的執行標準，幫助代理在生成 artifact 時保持一致、可讀和可交付。
- 08 State coverage Universal rules for what every interactive surface must render. The active DESIGN.md decides how each state looks; this file decides which states must exist and what they must contain. The single most reliable AI-design failure is shipping only the populated state.
- 09 Typography hierarchy Shared hierarchy contracts that layer on top of typography.md. This file does not repeat scale ranges or tracking values — those live in typography.md. This file defines how hierarchy behaves: entry points, rhythm, tension, and the conditions under which controlled violations are allowed. This contract applies per-surface (a page with multiple pacing resets may establish new primaries at intentional intervals), not globally.
