What it does

API Connector Builder is an agent skill from affaan-m/ECC. 通过匹配目标仓库现有的集成模式，构建一个新的API连接器或提供者。适用于在不发明第二种架构的情况下添加一个集成。

Its SKILL.md is about 330 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: The agent harness performance optimization system. Skills, instincts, memory, security, and research-first development for Claude Code, Codex, Opencode, Cursor and beyond. The licence is MIT.

Example prompts

  • “/api-connector-builder”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. 学习内部风格
  2. 缩小目标集成范围
  3. 按仓库原生层次构建
  4. 对照源模式验证

What it can do on your machine

Read from SKILL.md and the folder at commit ef648e0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

API Connector Builder loads about 328 tokens when it runs. Until then it costs about 20 tokens; SKILL.md has 78 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~20
When it runs · the whole SKILL.md, loaded when a task matches
~328

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

API 连接器构建器

当任务需要添加仓库原生的集成接口，而非仅通用 HTTP 客户端时使用此工具。

关键在于匹配宿主仓库的模式：

  • 连接器布局
  • 配置模式
  • 认证模型
  • 错误处理
  • 测试风格
  • 注册/发现机制

使用时机

  • "为此项目构建 Jira 连接器"
  • "按照现有模式添加 Slack 提供商"
  • "为此 API 创建新集成"
  • "构建符合仓库连接器风格的插件"

约束条件

  • 若仓库已有集成架构，不得自行发明新架构
  • 不得仅从供应商文档入手；应优先参考仓库内现有连接器
  • 若仓库需要注册机制、测试和文档，不得仅停留在传输代码层面
  • 若仓库有更新的当前模式，不得盲目复制旧连接器

工作流程

1. 学习内部风格

检查至少 2 个现有连接器/提供商，并映射：

  • 文件布局
  • 抽象边界
  • 配置模型
  • 重试/分页约定
  • 注册钩子
  • 测试夹具和命名规范
2. 缩小目标集成范围

仅定义仓库实际需要的接口：

  • 认证流程
  • 关键实体
  • 核心读写操作
  • 分页和速率限制
  • Webhook 或轮询模型
3. 按仓库原生层次构建

典型分层：

  • 配置/模式
  • 客户端/传输层
  • 映射层
  • 连接器/提供商入口
  • 注册机制
  • 测试
4. 对照源模式验证

新连接器应在代码库中显得自然，而非从不同生态导入。
