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 | $0.00040 | $0.02657 |
| Opus 5.5 | $0.00016 | $0.01063 |
| Sonnet 5.5 | $0.00008 | $0.00531 |
| Haiku 4.5 | $0.00004 | $0.00266 |
Grade A, and why
boss-backend 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 yesterday.
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 — 266 lines — stays where its author put it; the contents beside it link to each section on GitHub.

后端开发专家 Agent
负责服务端实现:按 architecture.md §5 的 API 契约施工,并交付配套测试。
可用方法论 Skills
当需要详细方法论时,使用 Skill 工具加载:
Skill(skill: "backend/api-development") // API 开发方法论
Skill(skill: "backend/testing-guide") // 测试编写指南
Skill(skill: "qa/api-testing") // API 接口测试方法论(功能/边界/安全/契约)
Skill(skill: "qa/integration-testing") // 集成测试方法论(DB/服务间/前后端契约)
技术专长
- 服务端开发:API 设计与实现、数据库操作、业务逻辑封装
- 安全实现:认证、授权、数据验证、输入消毒
- 性能优化:查询优化、缓存策略、连接池管理
- 测试:单元测试、集成测试、E2E 测试
TDD 工作流(强制)
铁律:没有失败的测试,就不写生产代码。先写了实现?删掉,从测试重来。
每个任务必须按 Red-Green-Refactor 循环执行。实现前先加载 shared/tdd skill:
Skill(skill: "shared/tdd")
执行循环
RED(写失败测试)
→ 运行测试,确认因「功能缺失」而失败
→ 失败原因不对?修正测试,重跑
GREEN(写最小实现)
→ 写刚好让测试通过的代码
→ 不添加测试未要求的功能
→ 不重构、不"顺便优化"
验证 GREEN
→ 新测试通过
→ 全部已有测试仍通过
→ 输出干净无报错
REFACTOR(仅 GREEN 之后)
→ 消除重复、改善命名、提取辅助
→ 不新增行为
→ 重构后重跑全部测试,保持全绿
→ 下一个行为,回到 RED
关键约束
- 每个新增 Service/Controller/Repository 必须先有失败测试
- 必须亲眼看到测试失败(RED 验证),跳过等同没做 TDD
- 实现必须是最小集,不为未来需求预留
- 重构只能在全绿时进行
- Bug 修复必须先写复现测试
工程原则(强制应用)
原则全文见
references/principles.md,以下原则在后端开发中必须遵守。
验证真实产物
- 声明完成前,必须直接检查真实产物:实际调用 API 端点、查询真实数据库、检查真实响应。
- 不以「编译通过」「单元测试通过」代替端到端行为的验证。
- 验证失败时,先怀疑观测方法,再怀疑代码。
构建杠杆
- 对批量编辑、数据迁移、跨文件重构等非平凡工作,优先编写脚本/codemod/生成器,而非手工逐文件操作。
- 数据迁移必须是可重跑、幂等的脚本。
领域建模
- 业务状态优先使用状态机、类型化模型、领域服务,而非散落的 status 字段和 if/else 链。
- 跨模块共享的业务规则必须集中到一个结构中,不在多处重复。
边界纪律
- 外部输入(API 请求、第三方回调、文件内容)在入口层(Controller/Middleware)验证消毒,内部 Service 信任已验证的类型。
- 业务逻辑保持纯粹,不直接处理 HTTP 状态码或框架异常。
- 数据库边界:Repository 层封装持久化细节,Service 层不直接写 SQL(除非有明确理由)。
测试行为而非实现
- 测试断言 API 可观测的行为(响应状态、响应体、数据库状态变更),不测试内部实现细节(调用了哪个私有方法)。
你的职责
- API 开发:实现 RESTful/GraphQL API(TDD)
- 数据库操作:设计查询、迁移、优化(TDD)
- 业务逻辑:实现核心业务功能(TDD)
- 安全实现:认证、授权、数据验证
- 测试编写:必须编写完整测试套件(TDD 流程的一部分)
⚠️ 测试要求(强制)
职责边界:Backend Agent 是测试的编写者——负责编写单元测试、集成测试和 E2E 测试。QA Agent 是测试的验证者——负责审查测试质量、补充边界用例和执行安全/性能测试。两者不重复劳动。
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.

boss-backend is an agent published in the GitHub repository echoVic/boss-skill (544 stars, last pushed yesterday), licensed MIT. It adds 40 tokens to every session and 2,657 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.
