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 | $0.00046 | $0.01035 |
| Opus 5.5 | $0.00018 | $0.00414 |
| Sonnet 5.5 | $0.00009 | $0.00207 |
| Haiku 4.5 | $0.00005 | $0.00103 |
Grade A, and why
feature-design 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
功能设计
按用户当前要作出的决定组合专业方法,逐步形成可评审、可实现、可验证的方案。本技能(Skill)不成为所有修改的前置,不规定固定阶段、必交文档或批准门禁,也不新增应用状态或能力契约(Capability Contract)。
收敛本轮目标
核对真实产品、已有方案和用户已确认的决定,区分当前事实、建议与未知项。说明本轮解决什么问题、用户得到什么结果、哪些方向暂不展开。较大目标可以保留整体关系,但先深入足以支持当前判断的一块,不把未来所有系统和模块变成本轮清单。
可从代码、页面、规范和权威资料核实的事实自行调查。次要缺口不改变方向时说明假设并继续;只有会改变目标、核心体验、权限或实际副作用的未知项才请求决定。用户已给出的范围、原型偏好和同范围授权持续有效。
围绕真实对象选择方法
按当前决定所需的深度,明确涉及的操作对象、身份、事实来源、实际使用入口及完成标准,再判断模块职责;不要求早期讨论先补齐底层模型,智能体(Agent)入口按实际适用性考虑。分别说明领域或模块负责什么、对象归谁维护,以及界面从哪里进入;导航位置不能代替架构决定,资料存放位置也不等于职责归属。检查已有能力能做什么,不从接口清单或统一增删改查开始设计。
按实际问题使用当前可用的专业技能(Skill),不要求每轮全部加载:
- 智能体(Agent)参与产品结果交付、共享成果或工作系统职责:
agent-first-design。 - 代码模块、对象职责及依赖:
code-architecture。 - 导航、信息层级、交互及反馈:
ux-design-laws。 - 需要独立查看的架构、时序、数据流或状态图:
archify。 - 已获制作授权的界面原型(UI Prototype):
ui-prototype。
方法的组合由当前问题决定,不建立固定调用顺序;专业能力缺失只影响依赖它的成果,其他设计继续。
用图示和界面支持判断
对象关系、执行边界、权限或环境隔离难以用文字判断时,用图示表达实际身份、事实来源、动作方向和边界。涉及外部资源时区分共享声明、执行位置、认证身份及真实目标;目录分组或颜色不等于访问隔离。明确哪些能力已经存在、哪些只是拟议设计,不以产品标志和连线代替关系说明。
涉及界面实质选择时,结合真实入口和关键状态说明方案。用户要求界面设计时,可用设计图或草图支持当前讨论;明确要求交互原型(UI Prototype)或已有同范围制作授权时,直接交给 ui-prototype,不重复询问。尚未明确偏好时只询问确会改变本轮成果的选择,不把普通界面讨论自动扩展为持久原型(UI Prototype)。原型(UI Prototype)放回现有导航、相邻模块和完整页面;制作、保存、任务归入及浏览器验证由该技能(Skill)负责,不复制其流程。未授权制作时继续其他已授权设计,不创建占位成果。
用代表场景检验并接续
涉及多种技术或系统时,按真实目标选一种有代表性的首例,把本轮决定涉及的使用路径讲清;发现、读取、操作、冲突和验证只展开当前判断需要的部分。其余技术只核对当前抽象能否容纳必要差异,不提前穷举或实现全部对接;发现共性不足时调整模型,不强行统一专业动作。
每轮只交付当前决定所需的推荐方案、边界、关键权衡、已确认与待解决事项,以及明确下一步。已有成果就地接续;需要正式规范时交给对应 OpenSpec 技能(Skill),不因讨论自动创建变更或重复文档。
仅认可设计、图示或原型(UI Prototype)不构成新的实现授权。没有对应授权时停在设计成果,不修改正式功能或操作外部系统;已有同范围实现授权且副作用未变化时继续有效,不因采用本技能(Skill)重复确认。
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.
- 10d ago First seen · 43 lines · 46 tokens per session scan A 1a12dcfeeb70
feature-design is a skill published in the GitHub repository BuildrAI/Buildr (28 stars, last pushed yesterday), licensed MIT. It adds 46 tokens to every session and 1,035 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 2026-10-16.
