Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00082 | $0.01137 |
| Opus 5 | $0.00041 | $0.00568 |
| Sonnet 5 | $0.00016 | $0.00227 |
| Haiku 4.5 | $0.00008 | $0.00114 |
Grade A, and why
ux-design-laws scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
用户体验设计法则
把用户体验法则当作发现问题和比较方案的启发式工具，不把法则名称当作设计结论。目标是帮助用户更可靠、更轻松地完成真实任务。
1. 建立设计现场
先确认当前工作属于哪一种：
- 设计：从目标和约束形成信息架构、页面结构或交互方案。
- 审查：从截图、原型、页面、代码或操作路径中发现问题。
- 权衡：比较多个方案，解释哪些用户收益与代价不同。
读取用户提供的真实材料；存在代码、现有页面或设计系统时先调查当前事实。至少明确主要用户、首要任务、使用环境、平台与输入方式。缺少的信息不会改变方向时作显式假设并继续；会改变核心流程、安全、权限或不可逆结果时再询问。
2. 选择相关法则
先读 法则索引，根据当前界面的可观察信号选择一至两个相关分组，再读取对应参考文件。不要为了展示完整而套用全部法则。
- 熟悉度、偏差、复杂度归属或整体策略：读 基础与设计策略。
- 信息密度、选项、注意力或记忆负担：读 信息与决策。
- 分组、层级、强调或视觉关系：读 视觉感知与布局。
- 点击、输入、响应、引导或连续操作：读 操作与系统反馈。
- 进度、完成动力、情绪高点或结束体验：读 旅程、动机与记忆。
每次只引用真正改变判断的法则。法则互相支持时合并为一个建议；法则产生不同方向时显式说明权衡。
3. 形成建议
按以下顺序判断：
- 用户明确目标、业务事实与授权边界。
- 安全、隐私、无障碍与结果可逆性。
- 首要任务能否正确完成。
- 用户已有心智模型与产品现有一致性。
- 理解成本、操作效率与错误恢复。
- 审美、愉悦和品牌表达。
法则只能支持建议，不能覆盖更高优先级的事实。把观察与推断分开，不把个人偏好包装成心理学结论，不声称某条法则必然提高转化率或满意度。
对每个重要问题给出：
- 证据：页面、流程或输入中的具体观察。
- 影响：它怎样阻碍主要用户完成首要任务。
- 法则：一至三条直接相关法则及其作用方向。
- 建议：具体到层级、位置、文案、状态或交互的变化。
- 权衡：收益、代价、例外和可能引入的新问题。
- 验证：可观察的任务结果、用户行为或产品指标。
优先处理阻断任务、造成严重误解或不可恢复错误的问题；其次处理高频任务的效率与理解；最后处理愉悦和视觉润色。默认给出最重要的三至五项，不用低价值建议淹没用户。
4. 约束与停止条件
- 法则是启发式原则，不替代真实用户研究、可用性测试、无障碍标准、平台规范或领域安全要求。
- 进度、稀缺、等待和视觉强调必须表达真实状态；避免虚假进度、制造焦虑、隐藏退出或诱导用户作出非自愿选择。
- 对现有界面做审查时只报告证据可支持的问题。看不到交互状态、响应时间或真实用户行为时，将结论标为待验证。
- 用户只要求分析或审查时停在建议，不生成原型、不修改代码。用户明确要求产出原型或实现时，把本技能的结果作为设计输入交给相应能力。
5. 输出格式
先给一句结论，再按优先级列建议。每项使用紧凑格式：
[优先级] 问题或机会
证据：...
影响：...
依据：<中文名称（English Name）>
建议：...
权衡：...
验证：...
设计模式还应给出核心流程与关键状态；审查模式应区分已观察事实和待验证假设；权衡模式应说明推荐方案及不选其他方案的具体原因。
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 3d ago First seen · 78 lines · 82 tokens per session scan A 553bd301687d
ux-design-laws is a skill published in the GitHub repository BuildrAI/Buildr (24 stars, last pushed 2d ago), licensed MIT. It adds 82 tokens to every session and 1,137 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-07.
