What it costs to keep this loaded
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 | $0.02023 |
| Opus 5.5 | $0.00022 | $0.00809 |
| Sonnet 5.5 | $0.00011 | $0.00405 |
| Haiku 4.5 | $0.00006 | $0.00202 |
Grade A, and why
development-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 29d 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.
How it starts
The opening of the file, as written. The whole thing — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Development Design
目标
回答“采用哪条主链路,为什么”。证据不足则返回调查。
实现前冻结验收与交付,不自行缩减用户结果。明确交付物与授权,给出 1–3 条“黄金验收”链路:目标 → 前提/真实入口 → 操作 → 响应 → 后续操作 → 结果 → 成败判定。入口、功能清单或技术调用链不能代替使用链路。标明等待成本、AI 自验证据及用户判断项;安装、测试和排障由 AI 承担。黄金验收覆盖完整标准但不替代 AI 自验;active contract 复用 IDs,按行为差异补矩阵。
验收适用性按用户行为与结果是否变化判断:没有新增 UI、只改底层或尚未发布,不构成豁免。纯内部重构且用户行为不变、规则维护或用户明确限定的源码/Review/原型交付,说明依据并提供匹配产物,不虚构产品使用链路。
稳定设计写入 docs/designs/YYYY-MM-DD-<topic>.design.md;局部方案可内联。大型交付的独立结果/决策须在实现前落盘;已有设计可引用,缺口和关键变更先补原文并链接历史。影响当前实现的选择先解决;分阶段须证明必要性。
有效合同形成或变化后,核对已有方案是否仍覆盖当前目标;受影响的设计、黄金验收和旧方案 Review 结论失效,补齐并复审后才能据此实现。未受影响部分继续复用,不把早期方案中的“未来扩展”当作新合同的范围决定。
产物分级
大型交付可按独立能力或独立审查需要拆专题设计:整体设计链接专题,专题引用上位约束并注明负责范围与适用状态,不复制全局合同。当前执行状态指向本项采用的设计和 Review 结论;拆文件不新增交付阶段。
输出设计结论与 design-document: required | not-required;feature/bugfix 共用产物门。
轻量设计限单 owner、无跨层合同/状态/兼容或真实分叉、局部可逆且不复用;写清问题、主链路、理由与验证。
出现以下任一情况,必须写入或更新稳定的 docs/designs 文档:
- L3-L4,或跨 package、runtime、projection、transport、持久化边界;
- 用户可见 L2 功能存在交互、信息架构或行为取舍;
- 改变状态 owner、生命周期、不变量、协议、兼容、迁移、fallback 或失败恢复;
- 有两个以上真实可行候选,需要记录选择与放弃理由;
- 设计会跨会话、跨批次、交给他人实现,或预计成为后续判断依据。
L0 文档修正和 lifecycle 可跳过的 L1 单路径改动无需进入;不按 diff、工时或文件数决定是否建文档。
计划门
进入 Implementation 前输出 plan: required | not-required。单批无法可信闭环时使用开发执行 Plan 合同,否则不建;Plan 不是新 phase。
设计合同
只展开与当前任务相关的维度:
- 大型交付记录“来源/版本 → 有效要求/ID → 设计位置 → 验证”,保留原始输入与全局约束;偏离写依据,未经授权不改用户结果。替代的旧输入保留溯源,原型不能只核对外观。
- 用户或系统可观察问题;
- producer、owner、consumer、已有约束与现有能力复用证据;
- 真实分叉时的 2-4 个候选:用户价值、owner、复杂度、可逆性、验证成本及主链路;路径明显不虚构候选;
- 状态、生命周期、不变量、失败/恢复、目录/公共入口/依赖边界;
- 第三方框架/runtime/协议:冻结上游执行、线程、生命周期、资源与错误合同及产品保留职责;偏离须有必要性、官方依据、验证和退出条件;
- 删除或禁止的平行路径,兼容/迁移/fallback 的必要性与退出条件;
- 非目标与最小验证标准。
性能/成本影响选型时,沿同一代表性任务比较等待、资源和成本,区分实测、估算与未知;引用 active contract 门槛并给出昂贵分支验收路径。缺关键数据先做最小实验,不凭理论冻结结论;无相关取舍不加基准测试。
跨运行宿主、存储归属、能力目录或主要用户链路的设计,按功能设计关对账旧能力、用户目标和候选能力;关键入口、权限边界或验收路径未定时保持未就绪。
证据足够时冻结占优方案;仅当选择显著改变用户行为或范围且无法判断偏好时,才请求用户决定。
思考投入
新项目、技术栈替换或新增影响运行/部署的关键依赖,必须在搭建产品脚手架、安装正式依赖和编码前按技术栈选型形成技术决策与依据;限定问题的可丢弃验证实验可先执行。用户指定技术仍核对适用性。沿用现有栈的普通小改只说明沿用依据,不例行比较或加载该参考。
What ships with it
6 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.

development-design is a skill published in the GitHub repository Peiiii/nextclaw (263 stars, last pushed yesterday), licensed MIT. It adds 56 tokens to every session and 2,023 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 2026-08-30.
