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 | $0.00084 | $0.00704 |
| Opus 5.5 | $0.00034 | $0.00282 |
| Sonnet 5.5 | $0.00017 | $0.00141 |
| Haiku 4.5 | $0.00008 | $0.00070 |
Grade A, and why
apply-yliu-frontend-practices 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 1mo 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
Apply Yliu Frontend Practices
对浏览器端 React、Vue 前端代码应用 Yliu 的个人工程实践。覆盖编写、重构和代码审查，不处理服务端模块。
确定优先级
按以下优先级决策：
- 用户本次明确要求。
- 项目已经稳定使用的规范、封装和依赖。
- 本技能的默认实践。
先检查依赖清单和任务涉及的现有实现。复用项目已有的成熟方案，不并行引入功能重复的库，也不为应用本技能而迁移无关代码。
按需读取规范
只完整读取当前任务涉及的引用文件；任务跨多个类别时读取所有相关文件：
- 涉及 Axios、API 模块、请求 Hook、业务错误或操作反馈时，读取 requests-and-feedback.md。
- 涉及 Hook/Composable 抽取、请求执行时机、路由性能、详情页面或 Pinia 数据来源时，读取 hooks-and-routing.md。网络 Hook 同时读取请求规范。
- 涉及 Loading、Error、Empty、布局稳定、危险操作、组件库、UnoCSS 或样式时，读取 ui-states-and-styling.md。
- 涉及新增、调整或审查测试时，读取 testing.md。
不要为了“了解全貌”默认加载全部引用；根据任务实际范围选择。
执行工作
编写或重构
- 读取相关引用文件。
- 查看项目中同类代码和依赖，确认已有约定。
- 只实现任务所需的最小改动。
- 让新增代码与项目风格一致，并应用引用文件中的默认实践。
- 运行与改动风险相称的检查。
代码审查
- 读取审查范围涉及的引用文件。
- 只报告真实、可定位的问题，说明影响和最小修复方向。
- 按严重程度排序，避免把个人偏好包装成缺陷。
- 用户没有要求修复时不要直接修改代码。
核心约束
- 不猜测业务成功状态；优先从项目中查找，仍不清晰时询问用户。
- 不让公共抽象隐式启动当前页面不需要的请求。
- 不让详情页依赖上一页内存状态，使用 URL 核心参数请求当前详情。
- 不重复展示请求反馈，也不把失败伪装成成功返回值。
- 不为了复用制造万能组件、薄包装 Hook 或新的重复依赖。
- 不测试普通文案和易变展示细节，除非用户明确要求。
What ships with it
5 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.

apply-yliu-frontend-practices is a skill published in the GitHub repository bosens-China/tc39-atlas (0 stars, last pushed yesterday), licensed MIT. It adds 84 tokens to every session and 704 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-08-31.
