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 | $0.00050 | $0.01157 |
| Opus 5 | $0.00025 | $0.00579 |
| Sonnet 5 | $0.00010 | $0.00231 |
| Haiku 4.5 | $0.00005 | $0.00116 |
Grade A, and why
bp-architecture-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 7d 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.

架构设计
使用场景：
workflow-system-designskill 在讨论 spec.md 4.1 方案概览 时加载本 skill。
第一性原理
架构设计的本质：在约束条件下，选择最优的 trade-off 来满足业务目标。
设计前：回顾 spec.md 前三节
在提出架构方案前，确保已理解：
| spec.md 章节 | 要回答的问题 |
|---|---|
| 1. 背景 | 要解决什么问题？现状是怎样的？ |
| 2. 目标 & 非目标 | 成功的标准是什么？什么不做？ |
| 3.1 功能性需求 | 系统需要具备哪些能力？ |
| 3.2 非功能性需求 | 性能、兼容性、可维护性约束？ |
如果非功能性需求可以量化，尽量量化（如 p99 延迟 < 100ms），但不强制要求所有场景都能量化。
模块划分
好的划分 = 减少协调成本 + 包含变化。
划分原则
| 原则 | 说明 | 检查点 |
|---|---|---|
| 按功能域划分 | 围绕业务能力而非技术层 | 相关的代码是否在一起？ |
| 高内聚 | 一起变化的代码放一起 | 修改一个功能要改几个模块？ |
| 低耦合 | 模块间依赖最小化 | 模块能否独立理解和测试？ |
| 明确所有权 | 每个模块有明确的数据和不变量 | 谁负责维护这块数据的一致性？ |
边界定义
// ✅ 明确的模块边界
namespace compaction {
// 公开接口
class CompactionScheduler { ... };
// 内部实现（不暴露）
namespace internal {
class CompactionTask { ... };
}
}
依赖管理
依赖方向
层次结构（从高到低）：
- 应用层 - 业务逻辑、用例编排
- 领域层 - 核心抽象、接口定义
- 基础设施层 - 具体实现（RocksDB、网络等）
依赖原则：高层依赖低层，依赖抽象接口而非具体实现
依赖规则
| 规则 | 说明 |
|---|---|
| 单向依赖 | 只能向下依赖，禁止向上依赖 |
| 禁止循环 | A→B→C→A 必须打破 |
| 依赖抽象 | 依赖接口而非具体实现 |
数据架构
数据决策决定正确性和运维复杂度。
| 决策点 | 需要明确 |
|---|---|
| 数据所有权 | 哪个模块是这份数据的 source of truth？ |
| 一致性模型 | 强一致 vs 最终一致？ |
| Schema 演进 | 向前/向后兼容？回滚方案？ |
接口设计
架构层关注接口原则，详细设计参见
bp-component-design的 4.2.2 节。
| 原则 | 说明 |
|---|---|
| 最小化 | 只暴露必要的接口 |
| 不泄露内部 | 使用专用 DTO |
| 版本兼容 | 接口变更需考虑向后兼容 |
与其他 Skill 协同
| 场景 | 加载 Skill |
|---|---|
| 涉及网络通信、多节点、一致性、故障恢复 | bp-distributed-systems |
| 涉及类/接口详细设计 | bp-component-design（4.2 节使用） |
4.1 方案概览 Checklist
在 spec.md 4.1 节，确认以下内容已讨论：
- 整体思路：用 1-2 句话描述方案核心
- 模块划分：涉及哪些模块？边界在哪？
- 依赖方向：模块间的依赖关系
- 数据流：数据如何流转？
- 关键 trade-off：为什么这样设计？牺牲了什么？
反模式
| 反模式 | 改进 |
|---|---|
| 循环依赖 (A→B→C→A) | 引入接口打破循环 |
| 边界模糊（多模块修改同一份数据） | 明确数据所有权 |
| 过度抽象 | 简单优先，按需抽象 |
| Big Ball of Mud | 逐步引入边界 |
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.
- 7d ago First seen · 135 lines · 50 tokens per session scan A cd68dfc049a0
bp-architecture-design is a skill published in the GitHub repository davidYichengWei/agentic-engineering-framework (158 stars, last pushed 5mo ago), licensed MIT. It adds 50 tokens to every session and 1,157 once invoked, about $0.0003 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 2026-08-30.
