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 | $0.00056 | $0.01086 |
| Opus 5.5 | $0.00022 | $0.00434 |
| Sonnet 5.5 | $0.00011 | $0.00217 |
| Haiku 4.5 | $0.00006 | $0.00109 |
Grade A, and why
frontend-development 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 10d 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
前端开发
先找到本次界面对应的真实页面、组件(Component)、主题和交互来源,再决定复用、扩展或新增。遵循项目技术栈和目录约定,不要求引入 Buildr Web 的框架或重构整个前端。
按实际职责开发
- 页面负责装配完整业务场景;组件(Component)承接可独立理解的展示与交互,相关输入、等待、成功和失败反馈保持在一起。
- 优先复用已有组件(Component)、主题变量和完整交互;有意改变已有行为时明确原因并修改共同来源,不能默默复制近似实现。复用范围包含产品导航与页面框架;修改或模拟局部内容不授权重画外围界面。
- 局部实现先留在所属功能,真实跨功能复用再提升到公共位置。不要为每个元素拆文件,也不要求所有组件(Component)无状态。
- 确需两种运行入口时,由入口接入数据、导航和业务操作,共享界面不直接绑定真实写入。保留正式入口的保存时机、错误反馈和版本校验。
- 样式延续当前主题与局部作用范围;新增颜色、间距或交互前先检查已有语义。让相关示例就近说明输入、操作结果及关键状态,不另建组件登记平台。
原型选择与授权
识别新增关键页面、主要布局或核心功能交互变化;这类变化存在实质设计选择且用户尚未表达偏好时,先询问是否需要界面原型(UI Prototype)。只有用户明确同意,才使用原型技能(UI Prototype Skill)。识别为“大改动”本身不是制作授权。
普通小改动、已明确的局部文案、样式和交互修复直接实现,不默认生成原型。只说“继续开发”不构成原型授权;同一任务已有明确授权或拒绝继续适用,不逐轮重复询问。此技能(Skill)可以持续指导开发,但不自动触发原型技能(UI Prototype Skill)。
用户决定按已有原型实施时,先核对确认版本与保存位置;尚未归入任务或仅留在临时预览位置时,在正式前端编辑前接续 ui-prototype 的“成果保存与接续”,由它保全成果、更新引用并验证适用的任务内展示,不重新询问是否制作原型。没有原型的普通局部修复仍直接实施。
原型源码已有执行位置时,在正式前端编辑前消费 task-triage 已核验的接续结果,在同一工作树(Worktree)和分支(Branch)继续开发;不因开始正式实现另建一套候选源码,也不因页面归档复制共享组件。没有源码位置时由任务分流按正常策略选择。
已有原型时先核对它与当前设计及源码的差异;以当前已确认设计和行为规范为准,不让演示中的临时操作覆盖真实业务语义。
已授权原型与正式页面的共同来源
需要原型时,两种入口导入同一份相关界面与主题源码。原型入口只提供模拟数据(Mock Data)、内存操作和受控导航,不导入真实会话、请求初始化或业务写入。仅替换数据不够:保存、跳转、上传等副作用也必须可替换。
例如现有下拉选择是“选中即保存”,正式入口传入已有保存能力,演示入口传入本地保存;不改成另一套多选确认流程。需要侧边说明时,复用已有侧边阅读容器与交互,只替换内容。
无可用来源或无法隔离真实操作时说明具体限制,不用手写近似冒充共同源码。新界面可以在已授权的隔离位置先形成候选组件(Component),审看后完善同一来源。
完成判断
指出本次复用或扩展的源文件,核对调用方、样式和副作用归属。按影响验证真实交互及必要状态;存在模拟入口时对照两种入口,说明模拟边界和未覆盖范围。共同源码变化后重建受影响原型并重新验证,不把旧画面的验证当成当前结果。
代码结构取舍沿用适用的代码架构技能(Code Architecture Skill);体验设计取舍沿用适用的体验设计技能(UX Design Skill)。不要求一次普通开发完整执行所有相关技能(Skill),不创建额外审批或验证状态。
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.

frontend-development is a skill published in the GitHub repository BuildrAI/Buildr (28 stars, last pushed yesterday), licensed MIT. It adds 56 tokens to every session and 1,086 once invoked, about $0.0002 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 2026-09-27.
