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 | $0.00127 | $0.02550 |
| Opus 5 | $0.00063 | $0.01275 |
| Sonnet 5 | $0.00025 | $0.00510 |
| Haiku 4.5 | $0.00013 | $0.00255 |
Grade A, and why
api-first-modular scanned grade A with 1 finding 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 3d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

API-First 模块化开发框架
后端每个功能 = 一个独立 API 包。前端只调 API + 渲染页面。全栈只做多个 API 包之间的编排。
这是强制约束,所有涉及前后端的开发和调试任务都必须遵循。

层级判断规则

|---|---|---|
| 页面布局、组件、样式、用户交互 | 前端 | 前端开发 |
| 数据库操作、算法、业务规则 | 后端API包 | 后端开发 |
| 多个API的组合调用、数据聚合 | 中间层 | 全栈开发 |
| 前后端数据格式不匹配 | 集成问题 | 先查API文档契约 |
后端 API 包标准开发流程(5 步闭环)
每个后端功能必须走完以下 5 步:
开发 ──► Checkfix ──► 封装 ──► API端点 ──► API文档
- 开发 (Implement) — 实现核心业务逻辑,编写单元测试,遵循单一职责
- Checkfix 闭环 — 执行技术栈对应的 lint/build 检查,失败则修复并复跑直至通过
- 封装 (Encapsulate) — 封装为独立模块/类/包,明确输入输出接口,隐藏内部实现
- API 暴露 (Expose) — 创建 API 端点(REST/GraphQL/RPC/WebSocket/SSE),统一响应格式,添加输入验证、错误处理、鉴权
- API 文档 (Document) — 按标准模板生成文档,文档是前端开发的唯一依据,必须与代码同步
API 文档标准模板
每个 API 包完成后,在 docs/api/ 或模块目录下生成:
# [模块名] API 文档
> 最后更新: [YYYY-MM-DD] | 版本: v1.0
## 概览
[模块的业务功能简介,1-2 句话]
## Base URL
`/api/v1/[module-name]`
## 认证方式
[Bearer Token / API Key / Session / 无认证]
## 端点列表
| 方法 | 路径 | 功能 | 认证 |
|------|------|------|------|
## 详细接口
### [接口名称]
- **路径**: `[METHOD] /api/v1/xxx`
- **功能**: [功能描述]
- **认证**: [是/否]
#### 请求参数
| 参数 | 类型 | 必填 | 默认值 | 说明 |
|------|------|------|--------|------|
#### 响应格式
**成功 (200)**:
{ "code": 0, "data": {...}, "message": "success" }
**失败 (4xx/5xx)**:
{ "code": 40001, "data": null, "message": "参数错误:field1 不能为空" }
#### 错误码
| 错误码 | HTTP状态码 | 含义 | 处理建议 |
|--------|-----------|------|----------|
#### 调用示例
[curl 示例]
## 特殊协议
[WebSocket / SSE / 长轮询等非标准协议的连接方式、事件格式、重连策略]
What ships with it
1 file 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.

api-first-modular is a skill published in the GitHub repository samqin123/Claude_skill_pool (2 stars, last pushed 6mo ago), licensed Apache-2.0. It adds 127 tokens to every session and 2,550 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
