AI Provider Bridge — Unified API for Anthropic/OpenAI/Google/xAI/Mistral/Ollama

One interface to call 6 AI providers. Swap models with a config change, not a code rewrite. Zero external dependencies.

Unified interface for 6 AI providers. One function call, any model.

Supported Providers

Provider	Models	API Key Env Var
Anthropic	Claude Opus, Sonnet, Haiku	INLINECODE0
OpenAI

Usage

CODEBLOCK0

Switching Providers

Change the model — provider is inferred from the prefix:

CODEBLOCK1

Model prefix → provider mapping:

- anthropic/ → Anthropic API
INLINECODE6 → OpenAI API
INLINECODE7 → Google Gemini API
INLINECODE8 → xAI Grok API
INLINECODE9 → Mistral API
INLINECODE10 → Local Ollama (no API key needed)

Zero Dependencies

Uses only Node.js built-in https and http modules. No npm install needed.

Changelog

v1.0.3

- Fixed API usage examples — config object uses camelCase property names (anthropicApiKey, openaiApiKey, googleApiKey, xaiApiKey, mistralApiKey), not flat apiKey or env var names. Model prefix determines provider (anthropic/model-name). Clarified sendMessage() as the correct method name.

v1.0.2

- Removed require('./token-compressor') reference entirely. TokenCompressor is now an inlined no-op pass-through class — no missing dependency, no external file needed. To enable compression, install the companion token-compressor skill and swap the class as noted in the code comments.
Removed automatic "Do not store or train on this data." appended to system prompts in OpenAI-compatible requests. This is the caller's responsibility — pass it via setSystemPrompt() if needed.

v1.0.1

- TokenCompressor dependency made optional — no-op fallback added when ./token-compressor is not present. Bridge works without it; messages pass through uncompressed.
Removed buildSystemPrompt() and workspaceContext option. These allowed embedding workspace files into system prompts sent to external APIs — data exposure risk. Use setSystemPrompt() directly.
Added env: section to frontmatter declaring required API keys per provider. All optional — only keys for providers you use are needed.

技能名称: AI Provider Bridge — Anthropic/OpenAI/Google/xAI/Mistral/Ollama统一API

详细描述:

AI Provider Bridge — Anthropic/OpenAI/Google/xAI/Mistral/Ollama统一API

一个接口调用6家AI提供商。通过配置更改即可切换模型，无需重写代码。零外部依赖。

6家AI提供商的统一接口。一次函数调用，任意模型。

支持的提供商

提供商	模型	API密钥环境变量
Anthropic	Claude Opus、Sonnet、Haiku	ANTHROPICAPIKEY
OpenAI

使用方法

javascript
const { AIBridge } = require(./src/ai-bridge);

const ai = new AIBridge({
currentModel: anthropic/claude-sonnet-4-20250514,
anthropicApiKey: process.env.ANTHROPICAPIKEY, // 仅Anthropic模型需要
openaiApiKey: process.env.OPENAIAPIKEY, // 仅OpenAI模型需要
googleApiKey: process.env.GOOGLEAPIKEY, // 仅Google模型需要
xaiApiKey: process.env.XAIAPIKEY, // 仅xAI模型需要
mistralApiKey: process.env.MISTRALAPIKEY, // 仅Mistral模型需要
ollamaHost: http://127.0.0.1:11434 // 可选，默认值如上
});

const response = await ai.sendMessage(法国的首都是哪里？);
console.log(response);

切换提供商

更改模型——提供商从前缀推断：

javascript
// 从云端切换到本地Ollama
ai.setModel(ollama/llama3.1:8b);

// 相同接口
const response = await ai.sendMessage(相同问题，免费模型);

模型前缀 → 提供商映射：

- anthropic/ → Anthropic API
openai/ → OpenAI API
google/ → Google Gemini API
xai/ → xAI Grok API
mistral/ → Mistral API
ollama/ → 本地Ollama（无需API密钥）

零依赖

仅使用Node.js内置的https和http模块。无需npm安装。

更新日志

v1.0.3

- 修复了API使用示例——配置对象使用驼峰命名属性名（anthropicApiKey、openaiApiKey、googleApiKey、xaiApiKey、mistralApiKey），而非扁平化的apiKey或环境变量名。模型前缀决定提供商（anthropic/model-name）。澄清了sendMessage()为正确的方法名。

v1.0.2

- 完全移除了require(./token-compressor)引用。TokenCompressor现在是一个内联的无操作透传类——无缺失依赖，无需外部文件。如需启用压缩，请安装配套的token-compressor技能，并按代码注释中的说明替换该类。
移除了在兼容OpenAI的请求中自动追加到系统提示的Do not store or train on this data.。这是调用者的责任——如有需要，请通过setSystemPrompt()传递。

v1.0.1

- TokenCompressor依赖变为可选——当./token-compressor不存在时添加了无操作回退。Bridge无需它即可工作；消息以未压缩形式透传。
移除了buildSystemPrompt()和workspaceContext选项。这些选项允许将工作区文件嵌入发送到外部API的系统提示中——存在数据泄露风险。请直接使用setSystemPrompt()。
在frontmatter中添加了env:部分，声明每个提供商所需的API密钥。全部可选——仅需使用到的提供商的密钥。
