-## Installation
+## Getting Started
 
-### Prerequisites
+CLIProxyAPI Guides: [https://help.router-for.me/](https://help.router-for.me/)
 
-- Go 1.24 or higher
-- A Google account with access to Gemini CLI models (optional)
-- An OpenAI account for Codex/GPT access (optional)
-- An Anthropic account for Claude Code access (optional)
-- A Qwen Chat account for Qwen Code access (optional)
+## Management API
 
-### Building from Source
+see [MANAGEMENT_API.md](https://help.router-for.me/management/api)
 
-1. Clone the repository:
-   ```bash
-   git clone https://github.com/luispater/CLIProxyAPI.git
-   cd CLIProxyAPI
-   ```
+## Amp CLI Support
 
-2. Build the application:
-   ```bash
-   go build -o cli-proxy-api ./cmd/server
-   ```
+CLIProxyAPI includes integrated support for [Amp CLI](https://ampcode.com) and Amp IDE extensions, enabling you to use your Google/ChatGPT/Claude OAuth subscriptions with Amp's coding tools:
 
-## Usage
+- Provider route aliases for Amp's API patterns (`/api/provider/{provider}/v1...`)
+- Management proxy for OAuth authentication and account features
+- Smart model fallback with automatic routing
+- **Model mapping** to route unavailable models to alternatives (e.g., `claude-opus-4.5` → `claude-sonnet-4`)
+- Security-first design with localhost-only management endpoints
 
-### Authentication
+**→ [Complete Amp CLI Integration Guide](docs/amp-cli-integration.md)**
 
-You can authenticate for Gemini, OpenAI, and/or Claude. All can coexist in the same `auth-dir` and will be load balanced.
+## SDK Docs
 
-- Gemini (Google):
-  ```bash
-  ./cli-proxy-api --login
-  ```
-  If you are an existing Gemini Code user, you may need to specify a project ID:
-  ```bash
-  ./cli-proxy-api --login --project_id <your_project_id>
-  ```
-  The local OAuth callback uses port `8085`.
-
-  Options: add `--no-browser` to print the login URL instead of opening a browser. The local OAuth callback uses port `8085`.
-
-- OpenAI (Codex/GPT via OAuth):
-  ```bash
-  ./cli-proxy-api --codex-login
-  ```
-  Options: add `--no-browser` to print the login URL instead of opening a browser. The local OAuth callback uses port `1455`.
-
-- Claude (Anthropic via OAuth):
-  ```bash
-  ./cli-proxy-api --claude-login
-  ```
-  Options: add `--no-browser` to print the login URL instead of opening a browser. The local OAuth callback uses port `54545`.
-
-- Qwen (Qwen Chat via OAuth):
-  ```bash
-  ./cli-proxy-api --qwen-login
-  ```
-  Options: add `--no-browser` to print the login URL instead of opening a browser. Use the Qwen Chat's OAuth device flow.
-
-
-### Starting the Server
-
-Once authenticated, start the server:
-
-```bash
-./cli-proxy-api
-```
-
-By default, the server runs on port 8317.
-
-### API Endpoints
-
-#### List Models
-
-```
-GET http://localhost:8317/v1/models
-```
-
-#### Chat Completions
-
-```
-POST http://localhost:8317/v1/chat/completions
-```
-
-Request body example:
-
-```json
-{
-  "model": "gemini-2.5-pro",
-  "messages": [
-    {
-      "role": "user",
-      "content": "Hello, how are you?"
-    }
-  ],
-  "stream": true
-}
-```
-
-Notes:
-- Use a `gemini-*` model for Gemini (e.g., "gemini-2.5-pro"), a `gpt-*` model for OpenAI (e.g., "gpt-5"), a `claude-*` model for Claude (e.g., "claude-3-5-sonnet-20241022"), or a `qwen-*` model for Qwen (e.g., "qwen3-coder-plus"). The proxy will route to the correct provider automatically.
-
-#### Claude Messages (SSE-compatible)
-
-```
-POST http://localhost:8317/v1/messages
-```
-
-### Using with OpenAI Libraries
-
-You can use this proxy with any OpenAI-compatible library by setting the base URL to your local server:
-
-#### Python (with OpenAI library)
-
-```python
-from openai import OpenAI
-
-client = OpenAI(
-    api_key="dummy",  # Not used but required
-    base_url="http://localhost:8317/v1"
-)
-
-# Gemini example
-gemini = client.chat.completions.create(
-    model="gemini-2.5-pro",
-    messages=[{"role": "user", "content": "Hello, how are you?"}]
-)
-
-# Codex/GPT example
-gpt = client.chat.completions.create(
-    model="gpt-5",
-    messages=[{"role": "user", "content": "Summarize this project in one sentence."}]
-)
-
-# Claude example (using messages endpoint)
-import requests
-claude_response = requests.post(
-    "http://localhost:8317/v1/messages",
-    json={
-        "model": "claude-3-5-sonnet-20241022",
-        "messages": [{"role": "user", "content": "Summarize this project in one sentence."}],
-        "max_tokens": 1000
-    }
-)
-
-print(gemini.choices[0].message.content)
-print(gpt.choices[0].message.content)
-print(claude_response.json())
-```
-
-#### JavaScript/TypeScript
-
-```javascript
-import OpenAI from 'openai';
-
-const openai = new OpenAI({
-  apiKey: 'dummy', // Not used but required
-  baseURL: 'http://localhost:8317/v1',
-});
-
-// Gemini
-const gemini = await openai.chat.completions.create({
-  model: 'gemini-2.5-pro',
-  messages: [{ role: 'user', content: 'Hello, how are you?' }],
-});
-
-// Codex/GPT
-const gpt = await openai.chat.completions.create({
-  model: 'gpt-5',
-  messages: [{ role: 'user', content: 'Summarize this project in one sentence.' }],
-});
-
-// Claude example (using messages endpoint)
-const claudeResponse = await fetch('http://localhost:8317/v1/messages', {
-  method: 'POST',
-  headers: { 'Content-Type': 'application/json' },
-  body: JSON.stringify({
-    model: 'claude-3-5-sonnet-20241022',
-    messages: [{ role: 'user', content: 'Summarize this project in one sentence.' }],
-    max_tokens: 1000
-  })
-});
-
-console.log(gemini.choices[0].message.content);
-console.log(gpt.choices[0].message.content);
-console.log(await claudeResponse.json());
-```

-# Quota exceeded behavior
-quota-exceeded:
-   switch-project: true # Whether to automatically switch to another project when a quota is exceeded
-   switch-preview-model: true # Whether to automatically switch to a preview model when a quota is exceeded
-
-# API keys for authentication

-  - "your-api-key-2"
-
-# API keys for official Generative Language API
-generative-language-api-key:
-  - "AIzaSy...01"
-  - "AIzaSy...02"
-  - "AIzaSy...03"
-  - "AIzaSy...04"
-  
-# Claude API keys

-    base-url: "https://www.example.com" # use the custom claude API endpoint
-
-# OpenAI compatibility providers
-openai-compatibility:

-    base-url: "https://openrouter.ai/api/v1" # The base URL of the provider.
-    api-keys: # The API keys for the provider. Add multiple keys if needed. Omit if unauthenticated access is allowed.
-      - "sk-or-v1-...b780"
-      - "sk-or-v1-...b781"
-    models: # The models supported by the provider.
-      - name: "moonshotai/kimi-k2:free" # The actual model name.
-        alias: "kimi-k2" # The alias used in the API.
-```
-
-### OpenAI Compatibility Providers
-
-Configure upstream OpenAI-compatible providers (e.g., OpenRouter) via `openai-compatibility`.
-
-- name: provider identifier used internally
-- base-url: provider base URL
-- api-keys: optional list of API keys (omit if provider allows unauthenticated requests)
-- models: list of mappings from upstream model `name` to local `alias`
-
-Example:
-
-```yaml
-openai-compatibility:
-  - name: "openrouter"
-    base-url: "https://openrouter.ai/api/v1"
-    api-keys:
-      - "sk-or-v1-...b780"
-      - "sk-or-v1-...b781"
-    models:
-      - name: "moonshotai/kimi-k2:free"
-        alias: "kimi-k2"
-```
-
-Usage: 
-
-Call OpenAI's endpoint `/v1/chat/completions` with `model` set to the alias (e.g., `kimi-k2`). The proxy routes to the configured provider/model automatically.
-
-Also, you may call Claude's endpoint `/v1/messages`, Gemini's `/v1beta/models/model-name:streamGenerateContent` or `/v1beta/models/model-name:generateContent`.
-
-And you can always use Gemini CLI with `CODE_ASSIST_ENDPOINT` set to `http://127.0.0.1:8317` for these OpenAI-compatible provider's models.
-
-
-### Authentication Directory
-
-The `auth-dir` parameter specifies where authentication tokens are stored. When you run the login command, the application will create JSON files in this directory containing the authentication tokens for your Google accounts. Multiple accounts can be used for load balancing.
-
-### API Keys
-
-The `api-keys` parameter allows you to define a list of API keys that can be used to authenticate requests to your proxy server. When making requests to the API, you can include one of these keys in the `Authorization` header:
-
-```
-Authorization: Bearer your-api-key-1
-```
-
-### Official Generative Language API
-
-The `generative-language-api-key` parameter allows you to define a list of API keys that can be used to authenticate requests to the official Generative Language API.
-
-## Hot Reloading
-
-The server watches the config file and the `auth-dir` for changes and reloads clients and settings automatically. You can add or remove Gemini/OpenAI token JSON files while the server is running; no restart is required.
-
-## Gemini CLI with multiple account load balancing
-
-Start CLI Proxy API server, and then set the `CODE_ASSIST_ENDPOINT` environment variable to the URL of the CLI Proxy API server.
-
-```bash
-export CODE_ASSIST_ENDPOINT="http://127.0.0.1:8317"
-```
-
-The server will relay the `loadCodeAssist`, `onboardUser`, and `countTokens` requests. And automatically load balance the text generation requests between the multiple accounts.
-
-> [!NOTE]  
-> This feature only allows local access because there is currently no way to authenticate the requests.   
-> 127.0.0.1 is hardcoded for load balancing.
-
-## Claude Code with multiple account load balancing
-
-Start CLI Proxy API server, and then set the `ANTHROPIC_BASE_URL`, `ANTHROPIC_AUTH_TOKEN`, `ANTHROPIC_MODEL`, `ANTHROPIC_SMALL_FAST_MODEL` environment variables.
-
-Using Gemini models:
-```bash
-export ANTHROPIC_BASE_URL=http://127.0.0.1:8317
-export ANTHROPIC_AUTH_TOKEN=sk-dummy
-export ANTHROPIC_MODEL=gemini-2.5-pro
-export ANTHROPIC_SMALL_FAST_MODEL=gemini-2.5-flash
-```
-
-Using OpenAI models:
-```bash
-export ANTHROPIC_BASE_URL=http://127.0.0.1:8317
-export ANTHROPIC_AUTH_TOKEN=sk-dummy
-export ANTHROPIC_MODEL=gpt-5
-export ANTHROPIC_SMALL_FAST_MODEL=gpt-5-nano
-```
-
-Using Claude models:
-```bash
-export ANTHROPIC_BASE_URL=http://127.0.0.1:8317
-export ANTHROPIC_AUTH_TOKEN=sk-dummy
-export ANTHROPIC_MODEL=claude-sonnet-4-20250514
-export ANTHROPIC_SMALL_FAST_MODEL=claude-3-5-haiku-20241022
-```
-
-Using Qwen models:
-```bash
-export ANTHROPIC_BASE_URL=http://127.0.0.1:8317
-export ANTHROPIC_AUTH_TOKEN=sk-dummy
-export ANTHROPIC_MODEL=qwen3-coder-plus
-export ANTHROPIC_SMALL_FAST_MODEL=qwen3-coder-flash
-```

-### 配置文件示例
-
-```yaml
-# 服务器端口
-port: 8317
-
-# 身份验证目录（支持 ~ 表示主目录）。如果你使用Windows，建议设置成`C:/cli-proxy-api/`。
-auth-dir: "~/.cli-proxy-api"
-
-# 启用调试日志
-debug: false
-
-# 代理URL。支持socks5/http/https协议。例如：socks5://user:pass@192.168.1.1:1080/
-proxy-url: ""
-
-# 请求重试次数。如果HTTP响应码为403、408、500、502、503或504，将会触发重试。
-request-retry: 3
-
-
-# 配额超限行为
-quota-exceeded:
-   switch-project: true # 当配额超限时是否自动切换到另一个项目
-   switch-preview-model: true # 当配额超限时是否自动切换到预览模型
-
-# 用于本地身份验证的 API 密钥
-api-keys:
-  - "your-api-key-1"
-  - "your-api-key-2"
-
-# AIStduio Gemini API 的 API 密钥
-generative-language-api-key:
-  - "AIzaSy...01"
-  - "AIzaSy...02"
-  - "AIzaSy...03"
-  - "AIzaSy...04"
-
-# Claude API keys
-claude-api-key:
-  - api-key: "sk-atSM..." # use the official claude API key, no need to set the base url
-  - api-key: "sk-atSM..."
-    base-url: "https://www.example.com" # use the custom claude API endpoint
-
-# OpenAI 兼容提供商
-openai-compatibility:
-  - name: "openrouter" # 提供商的名称；它将被用于用户代理和其它地方。
-    base-url: "https://openrouter.ai/api/v1" # 提供商的基础URL。
-    api-keys: # 提供商的API密钥。如果需要，可以添加多个密钥。如果允许未经身份验证的访问，则可以省略。
-      - "sk-or-v1-...b780"
-      - "sk-or-v1-...b781"
-    models: # 提供商支持的模型。
-      - name: "moonshotai/kimi-k2:free" # 实际的模型名称。
-        alias: "kimi-k2" # 在API中使用的别名。
-```
-
-### OpenAI 兼容上游提供商
-
-通过 `openai-compatibility` 配置上游 OpenAI 兼容提供商（例如 OpenRouter）。
-
-- name：内部识别名
-- base-url：提供商基础地址
-- api-keys：可选，多密钥轮询（若提供商支持无鉴权可省略）
-- models：将上游模型 `name` 映射为本地可用 `alias`
-
-示例：
-
-```yaml
-openai-compatibility:
-  - name: "openrouter"
-    base-url: "https://openrouter.ai/api/v1"
-    api-keys:
-      - "sk-or-v1-...b780"
-      - "sk-or-v1-...b781"
-    models:
-      - name: "moonshotai/kimi-k2:free"
-        alias: "kimi-k2"
-```
-
-使用方式：在 `/v1/chat/completions` 中将 `model` 设为别名（如 `kimi-k2`），代理将自动路由到对应提供商与模型。
-
-并且，对于这些与OpenAI兼容的提供商模型，您始终可以通过将CODE_ASSIST_ENDPOINT设置为 http://127.0.0.1:8317 来使用Gemini CLI。
-
-### 身份验证目录
-
-`auth-dir` 参数指定身份验证令牌的存储位置。当您运行登录命令时，应用程序将在此目录中创建包含 Google 账户身份验证令牌的 JSON 文件。多个账户可用于轮询。
-
-### API 密钥
-
-`api-keys` 参数允许您定义可用于验证对代理服务器请求的 API 密钥列表。在向 API 发出请求时，您可以在 `Authorization` 标头中包含其中一个密钥：
-
-```
-Authorization: Bearer your-api-key-1
-```
-
-### 官方生成式语言 API
-
-`generative-language-api-key` 参数允许您定义可用于验证对官方 AIStudio Gemini API 请求的 API 密钥列表。
-
-## 热更新
-
-服务会监听配置文件与 `auth-dir` 目录的变化并自动重新加载客户端与配置。您可以在运行中新增/移除 Gemini/OpenAI 的令牌 JSON 文件，无需重启服务。
-
-## Gemini CLI 多账户负载均衡
-
-启动 CLI 代理 API 服务器，然后将 `CODE_ASSIST_ENDPOINT` 环境变量设置为 CLI 代理 API 服务器的 URL。
-
-```bash
-export CODE_ASSIST_ENDPOINT="http://127.0.0.1:8317"
-```
-
-服务器将中继 `loadCodeAssist`、`onboardUser` 和 `countTokens` 请求。并自动在多个账户之间轮询文本生成请求。
-
-> [!NOTE]  
-> 此功能仅允许本地访问，因为找不到一个可以验证请求的方法。
-> 所以只能强制只有 `127.0.0.1` 可以访问。
-

+# Amp CLI Integration Guide
+
+This guide explains how to use CLIProxyAPI with Amp CLI and Amp IDE extensions, enabling you to use your existing Google/ChatGPT/Claude subscriptions (via OAuth) with Amp's CLI.
+
+## Table of Contents
+
+- [Overview](#overview)
+  - [Which Providers Should You Authenticate?](#which-providers-should-you-authenticate)
+- [Architecture](#architecture)
+- [Configuration](#configuration)
+  - [Model Mapping Configuration](#model-mapping-configuration)
+- [Setup](#setup)
+- [Usage](#usage)
+- [Troubleshooting](#troubleshooting)
+
+## Overview
+
+The Amp CLI integration adds specialized routing to support Amp's API patterns while maintaining full compatibility with all existing CLIProxyAPI features. This allows you to use both traditional CLIProxyAPI features and Amp CLI with the same proxy server.
+
+### Key Features
+
+- **Provider route aliases**: Maps Amp's `/api/provider/{provider}/v1...` patterns to CLIProxyAPI handlers
+- **Management proxy**: Forwards OAuth and account management requests to Amp's control plane
+- **Smart fallback**: Automatically routes unconfigured models to ampcode.com
+- **Model mapping**: Route unavailable models to alternatives you have access to (e.g., `claude-opus-4.5` → `claude-sonnet-4`)
+- **Secret management**: Configurable precedence (config > env > file) with 5-minute caching
+- **Security-first**: Management routes restricted to localhost by default
+- **Automatic gzip handling**: Decompresses responses from Amp upstream
+
+### What You Can Do
+
+- Use Amp CLI with your Google account (Gemini 3 Pro Preview, Gemini 2.5 Pro, Gemini 2.5 Flash)
+- Use Amp CLI with your ChatGPT Plus/Pro subscription (GPT-5, GPT-5 Codex models)
+- Use Amp CLI with your Claude Pro/Max subscription (Claude Sonnet 4.5, Opus 4.1)
+- Use Amp IDE extensions (VS Code, Cursor, Windsurf, etc.) with the same proxy
+- Run multiple CLI tools (Factory + Amp) through one proxy server
+- Route unconfigured models automatically through ampcode.com
+
+### Which Providers Should You Authenticate?
+
+**Important**: The providers you need to authenticate depend on which models and features your installed version of Amp currently uses. Amp employs different providers for various agent modes and specialized subagents:
+
+- **Smart mode**: Uses Google/Gemini models (Gemini 3 Pro)
+- **Rush mode**: Uses Anthropic/Claude models (Claude Haiku 4.5)
+- **Oracle subagent**: Uses OpenAI/GPT models (GPT-5 medium reasoning)
+- **Librarian subagent**: Uses Anthropic/Claude models (Claude Sonnet 4.5)
+- **Search subagent**: Uses Anthropic/Claude models (Claude Haiku 4.5)
+- **Review feature**: Uses Google/Gemini models (Gemini 2.5 Flash-Lite)
+
+For the most current information about which models Amp uses, see the **[Amp Models Documentation](https://ampcode.com/models)**.
+
+#### Fallback Behavior
+
+CLIProxyAPI uses a smart fallback system:
+
+1. **Provider authenticated locally** (`--login`, `--codex-login`, `--claude-login`):
+   - Requests use **your OAuth subscription** (ChatGPT Plus/Pro, Claude Pro/Max, Google account)
+   - You benefit from your subscription's included usage quotas
+   - No Amp credits consumed
+
+2. **Provider NOT authenticated locally**:
+   - Requests automatically forward to **ampcode.com**
+   - Uses Amp's backend provider connections
+   - **Requires Amp credits** if the provider is paid (OpenAI, Anthropic paid tiers)
+   - May result in errors if Amp credit balance is insufficient
+
+**Recommendation**: Authenticate all providers you have subscriptions for to maximize value and minimize Amp credit usage. If you don't have subscriptions to all providers Amp uses, ensure you have sufficient Amp credits available for fallback requests.
+
+## Architecture
+
+### Request Flow
+
+```
+Amp CLI/IDE
+  ↓
+  ├─ Provider API requests (/api/provider/{provider}/v1/...)
+  │   ↓
+  │   ├─ Model configured locally?
+  │   │   YES → Use local OAuth tokens (OpenAI/Claude/Gemini handlers)
+  │   │   NO  ↓
+  │   │       ├─ Model mapping configured?
+  │   │       │   YES → Rewrite model → Use local handler (free)
+  │   │       │   NO  → Forward to ampcode.com (uses Amp credits)
+  │   ↓
+  │   Response
+  │
+  └─ Management requests (/api/auth, /api/user, /api/threads, ...)
+      ↓
+      ├─ Localhost check (security)
+      ↓
+      └─ Reverse proxy to ampcode.com
+          ↓
+          Response (auto-decompressed if gzipped)
+```
+
+### Components
+
+The Amp integration is implemented as a modular routing module (`internal/api/modules/amp/`) with these components:
+
+1. **Route Aliases** (`routes.go`): Maps Amp-style paths to standard handlers
+2. **Reverse Proxy** (`proxy.go`): Forwards management requests to ampcode.com
+3. **Fallback Handler** (`fallback_handlers.go`): Routes unconfigured models to ampcode.com
+4. **Secret Management** (`secret.go`): Multi-source API key resolution with caching
+5. **Main Module** (`amp.go`): Orchestrates registration and configuration
+
+## Configuration
+
+### Basic Configuration
+
+Add these fields to your `config.yaml`:
+
+```yaml
+# Amp upstream control plane (required for management routes)
+amp-upstream-url: "https://ampcode.com"
+
+# Optional: Override API key (otherwise uses env or file)
+# amp-upstream-api-key: "your-amp-api-key"
+
+# Security: restrict management routes to localhost (recommended)
+amp-restrict-management-to-localhost: true
+```
+
+### Model Mapping Configuration
+
+When Amp CLI requests a model that you don't have access to, you can configure mappings to route those requests to alternative models that you DO have available. This avoids consuming Amp credits for models you could handle locally.
+
+```yaml
+# Route unavailable models to alternatives
+amp-model-mappings:
+  # Example: Route Claude Opus 4.5 requests to Claude Sonnet 4
+  - from: "claude-opus-4.5"
+    to: "claude-sonnet-4"
+  
+  # Example: Route GPT-5 requests to Gemini 2.5 Pro
+  - from: "gpt-5"
+    to: "gemini-2.5-pro"
+  
+  # Example: Map older model names to newer versions
+  - from: "claude-3-opus-20240229"
+    to: "claude-3-5-sonnet-20241022"
+```
+
+**How it works:**
+
+1. Amp CLI requests a model (e.g., `claude-opus-4.5`)
+2. CLIProxyAPI checks if a local provider is available for that model
+3. If not available, it checks the model mappings
+4. If a mapping exists, the request is rewritten to use the target model
+5. The request is then handled locally (free, using your OAuth subscription)
+
+**Benefits:**
+- **Save Amp credits**: Use your local subscriptions instead of forwarding to ampcode.com
+- **Hot-reload**: Mappings can be updated without restarting the proxy
+- **Structured logging**: Clear logs show when mappings are applied
+
+**Routing Decision Logs:**
+
+The proxy logs each routing decision with structured fields:
+
+```
+[AMP] Using local provider for model: gemini-2.5-pro          # Local provider (free)
+[AMP] Model mapped: claude-opus-4.5 -> claude-sonnet-4        # Mapping applied (free)
+[AMP] Forwarding to ampcode.com (uses Amp credits) - model_id: gpt-5  # Fallback (costs credits)
+```
+
+### Secret Resolution Precedence
+
+The Amp module resolves API keys using this precedence order:
+
+| Source | Key | Priority | Cache |
+|--------|-----|----------|-------|
+| Config file | `amp-upstream-api-key` | High | No |
+| Environment | `AMP_API_KEY` | Medium | No |
+| Amp secrets file | `~/.local/share/amp/secrets.json` | Low | 5 min |
+
+**Recommendation**: Use the Amp secrets file (lowest precedence) for normal usage. This file is automatically managed by `amp login`.
+
+### Security Settings
+
+**`amp-restrict-management-to-localhost`** (default: `true`)
+
+When enabled, management routes (`/api/auth`, `/api/user`, `/api/threads`, etc.) only accept connections from localhost (127.0.0.1, ::1). This prevents:
+- Drive-by browser attacks
+- Remote access to management endpoints
+- CORS-based attacks
+- Header spoofing attacks (e.g., `X-Forwarded-For: 127.0.0.1`)
+
+#### How It Works
+
+This restriction uses the **actual TCP connection address** (`RemoteAddr`), not HTTP headers like `X-Forwarded-For`. This prevents header spoofing attacks but has important implications:
+
+- ✅ **Works for direct connections**: Running CLIProxyAPI directly on your machine or server
+- ⚠️ **May not work behind reverse proxies**: If deploying behind nginx, Cloudflare, or other proxies, the connection will appear to come from the proxy's IP, not localhost
+
+#### Reverse Proxy Deployments
+
+If you need to run CLIProxyAPI behind a reverse proxy (nginx, Caddy, Cloudflare Tunnel, etc.):
+
+1. **Disable the localhost restriction**:
+   ```yaml
+   amp-restrict-management-to-localhost: false
+   ```
+
+2. **Use alternative security measures**:
+   - Firewall rules restricting access to management routes
+   - Proxy-level authentication (HTTP Basic Auth, OAuth)
+   - Network-level isolation (VPN, Tailscale, Cloudflare Access)
+   - Bind CLIProxyAPI to `127.0.0.1` only and access via SSH tunnel
+
+3. **Example nginx configuration** (blocks external access to management routes):
+   ```nginx
+   location /api/auth { deny all; }
+   location /api/user { deny all; }
+   location /api/threads { deny all; }
+   location /api/internal { deny all; }
+   ```
+
+**Important**: Only disable `amp-restrict-management-to-localhost` if you understand the security implications and have other protections in place.
+
+## Setup
+
+### 1. Configure CLIProxyAPI
+
+Create or edit `config.yaml`:
+
+```yaml
+port: 8317
+auth-dir: "~/.cli-proxy-api"
+
+# Amp integration
+amp-upstream-url: "https://ampcode.com"
+amp-restrict-management-to-localhost: true
+
+# Other standard settings...
+debug: false
+logging-to-file: true
+```
+
+### 2. Authenticate with Providers
+
+Run OAuth login for the providers you want to use:
+
+**Google Account (Gemini 2.5 Pro, Gemini 2.5 Flash, Gemini 3 Pro Preview):**
+```bash
+./cli-proxy-api --login
+```
+
+**ChatGPT Plus/Pro (GPT-5, GPT-5 Codex):**
+```bash
+./cli-proxy-api --codex-login
+```
+
+**Claude Pro/Max (Claude Sonnet 4.5, Opus 4.1):**
+```bash
+./cli-proxy-api --claude-login
+```
+
+Tokens are saved to:
+- Gemini: `~/.cli-proxy-api/gemini-<email>.json`
+- OpenAI Codex: `~/.cli-proxy-api/codex-<email>.json`
+- Claude: `~/.cli-proxy-api/claude-<email>.json`
+
+### 3. Start the Proxy
+
+```bash
+./cli-proxy-api --config config.yaml
+```
+
+Or run in background with tmux (recommended for remote servers):
+
+```bash
+tmux new-session -d -s proxy "./cli-proxy-api --config config.yaml"
+```
+
+### 4. Configure Amp CLI
+
+#### Option A: Settings File
+
+Edit `~/.config/amp/settings.json`:
+
+```json
+{
+  "amp.url": "http://localhost:8317"
+}
+```
+
+#### Option B: Environment Variable
+
+```bash
+export AMP_URL=http://localhost:8317
+```
+
+### 5. Login and Use Amp
+
+Login through the proxy (proxied to ampcode.com):
+
+```bash
+amp login
+```
+
+Use Amp as normal:
+
+```bash
+amp "Write a hello world program in Python"
+```
+
+### 6. (Optional) Configure Amp IDE Extension
+
+The proxy also works with Amp IDE extensions for VS Code, Cursor, Windsurf, etc.
+
+1. Open Amp extension settings in your IDE
+2. Set **Amp URL** to `http://localhost:8317`
+3. Login with your Amp account
+4. Start using Amp in your IDE
+
+Both CLI and IDE can use the proxy simultaneously.
+
+## Usage
+
+### Supported Routes
+
+#### Provider Aliases (Always Available)
+
+These routes work even without `amp-upstream-url` configured:
+
+- `/api/provider/openai/v1/chat/completions`
+- `/api/provider/openai/v1/responses`
+- `/api/provider/anthropic/v1/messages`
+- `/api/provider/google/v1beta/models/:action`
+
+Amp CLI calls these routes with your OAuth-authenticated models configured in CLIProxyAPI.
+
+#### Management Routes (Require `amp-upstream-url`)
+
+These routes are proxied to ampcode.com:
+
+- `/api/auth` - Authentication
+- `/api/user` - User profile
+- `/api/meta` - Metadata
+- `/api/threads` - Conversation threads
+- `/api/telemetry` - Usage telemetry
+- `/api/internal` - Internal APIs
+
+**Security**: Restricted to localhost by default.
+
+### Model Fallback Behavior
+
+When Amp requests a model:
+
+1. **Check local configuration**: Does CLIProxyAPI have OAuth tokens for this model's provider?
+2. **If YES**: Route to local handler (use your OAuth subscription)
+3. **If NO**: Check if a model mapping exists
+4. **If mapping exists**: Rewrite request to mapped model → Route to local handler (free)
+5. **If no mapping**: Forward to ampcode.com (uses Amp credits)
+
+This enables seamless mixed usage:
+- Models you've configured (Gemini, ChatGPT, Claude) → Your OAuth subscriptions
+- Models with mappings configured → Routed to alternative local models (free)
+- Models you haven't configured and have no mapping → Amp's default providers (uses credits)
+
+### Example API Calls
+
+**Chat completion with local OAuth:**
+```bash
+curl http://localhost:8317/api/provider/openai/v1/chat/completions \
+  -H "Content-Type: application/json" \
+  -d '{
+    "model": "gpt-5",
+    "messages": [{"role": "user", "content": "Hello"}]
+  }'
+```
+
+**Management endpoint (localhost only):**
+```bash
+curl http://localhost:8317/api/user
+```
+
+## Troubleshooting
+
+### Common Issues
+
+| Symptom | Likely Cause | Fix |
+|---------|--------------|-----|
+| 404 on `/api/provider/...` | Incorrect route path | Ensure exact path: `/api/provider/{provider}/v1...` |
+| 403 on `/api/user` | Non-localhost request | Run from same machine or disable `amp-restrict-management-to-localhost` (not recommended) |
+| 401/403 from provider | Missing/expired OAuth | Re-run `--codex-login` or `--claude-login` |
+| Amp gzip errors | Response decompression issue | Update to latest build; auto-decompression should handle this |
+| Models not using proxy | Wrong Amp URL | Verify `amp.url` setting or `AMP_URL` environment variable |
+| CORS errors | Protected management endpoint | Use CLI/terminal, not browser |
+
+### Diagnostics
+
+**Check proxy logs:**
+```bash
+# If logging-to-file: true
+tail -f logs/requests.log
+
+# If running in tmux
+tmux attach-session -t proxy
+```
+
+**Enable debug mode** (temporarily):
+```yaml
+debug: true
+```
+
+**Test basic connectivity:**
+```bash
+# Check if proxy is running
+curl http://localhost:8317/v1/models
+
+# Check Amp-specific route
+curl http://localhost:8317/api/provider/openai/v1/models
+```
+
+**Verify Amp configuration:**
+```bash
+# Check if Amp is using proxy
+amp config get amp.url
+
+# Or check environment
+echo $AMP_URL
+```
+
+### Security Checklist
+
+- ✅ Keep `amp-restrict-management-to-localhost: true` (default)
+- ✅ Don't expose proxy publicly (bind to localhost or use firewall/VPN)
+- ✅ Use the Amp secrets file (`~/.local/share/amp/secrets.json`) managed by `amp login`
+- ✅ Rotate OAuth tokens periodically by re-running login commands
+- ✅ Store config and auth-dir on encrypted disk if handling sensitive data
+- ✅ Keep proxy binary up to date for security fixes

+# Amp CLI 集成指南
+
+本指南说明如何在 Amp CLI 和 Amp IDE 扩展中使用 CLIProxyAPI，通过 OAuth 让你能够把已有的 Google/ChatGPT/Claude 订阅与 Amp 的 CLI 一起使用。

+
+## 概述
+
+Amp CLI 集成为 Amp 的 API 模式添加了专用路由，同时保持与现有 CLIProxyAPI 功能的完全兼容。这样你可以在同一个代理服务器上同时使用传统 CLIProxyAPI 功能和 Amp CLI。
+
+### 主要特性
+
+- **提供者路由别名**：将 Amp 的 `/api/provider/{provider}/v1...` 路径映射到 CLIProxyAPI 处理器
+- **管理代理**：将 OAuth 和账号管理请求转发到 Amp 控制平面
+- **智能回退**：自动将未配置的模型路由到 ampcode.com
+- **密钥管理**：可配置优先级（配置 > 环境变量 > 文件），缓存 5 分钟
+- **安全优先**：管理路由默认限制为 localhost
+- **自动 gzip 处理**：自动解压来自 Amp 上游的响应
+
+### 你可以做什么
+
+- 使用 Amp CLI 搭配你的 Google 账号（Gemini 3 Pro Preview、Gemini 2.5 Pro、Gemini 2.5 Flash）
+- 使用 Amp CLI 搭配你的 ChatGPT Plus/Pro 订阅（GPT-5、GPT-5 Codex 模型）
+- 使用 Amp CLI 搭配你的 Claude Pro/Max 订阅（Claude Sonnet 4.5、Opus 4.1）
+- 将 Amp IDE 扩展（VS Code、Cursor、Windsurf 等）与同一个代理一起使用
+- 通过一个代理同时运行多个 CLI 工具（Factory + Amp）
+- 将未配置的模型自动路由到 ampcode.com
+
+### 应该认证哪些服务提供商？
+
+**重要**：需要认证的提供商取决于你安装的 Amp 版本当前使用的模型和功能。Amp 的不同智能模式和子代理会使用不同的提供商：
+
+- **Smart 模式**：使用 Google/Gemini 模型（Gemini 3 Pro）
+- **Rush 模式**：使用 Anthropic/Claude 模型（Claude Haiku 4.5）
+- **Oracle 子代理**：使用 OpenAI/GPT 模型（GPT-5 medium reasoning）
+- **Librarian 子代理**：使用 Anthropic/Claude 模型（Claude Sonnet 4.5）
+- **Search 子代理**：使用 Anthropic/Claude 模型（Claude Haiku 4.5）
+- **Review 功能**：使用 Google/Gemini 模型（Gemini 2.5 Flash-Lite）
+
+有关 Amp 当前使用哪些模型的最新信息，请参阅 **[Amp 模型文档](https://ampcode.com/models)**。
+
+#### 回退行为
+
+CLIProxyAPI 采用智能回退机制：
+
+1. **本地已认证提供商**（`--login`、`--codex-login`、`--claude-login`）：
+   - 请求使用**你的 OAuth 订阅**（ChatGPT Plus/Pro、Claude Pro/Max、Google 账号）
+   - 享受订阅自带的额度
+   - 不消耗 Amp 额度
+
+2. **本地未认证提供商**：
+   - 请求自动转发到 **ampcode.com**
+   - 使用 Amp 的后端提供商连接
+   - 如果提供商是付费的（OpenAI、Anthropic 付费档），**需要消耗 Amp 额度**
+   - 若 Amp 额度不足，可能产生错误
+
+**建议**：对你有订阅的所有提供商都进行认证，以最大化价值并尽量减少 Amp 额度消耗。如果没有覆盖 Amp 使用的全部提供商，请确保为回退请求准备足够的 Amp 额度。
+
+## 架构
+
+### 请求流
+
+```
+Amp CLI/IDE
+  ↓
+  ├─ Provider API requests (/api/provider/{provider}/v1/...)
+  │   ↓
+  │   ├─ Model configured locally?
+  │   │   YES → Use local OAuth tokens (OpenAI/Claude/Gemini handlers)
+  │   │   NO  → Forward to ampcode.com (reverse proxy)
+  │   ↓
+  │   Response
+  │
+  └─ Management requests (/api/auth, /api/user, /api/threads, ...)
+      ↓
+      ├─ Localhost check (security)
+      ↓
+      └─ Reverse proxy to ampcode.com
+          ↓
+          Response (auto-decompressed if gzipped)
+```
+
+### 组件
+
+Amp 集成以模块化路由模块（`internal/api/modules/amp/`）实现，包含以下组件：
+
+1. **路由别名**（`routes.go`）：将 Amp 风格的路径映射到标准处理器
+2. **反向代理**（`proxy.go`）：将管理请求转发到 ampcode.com
+3. **回退处理器**（`fallback_handlers.go`）：将未配置的模型路由到 ampcode.com
+4. **密钥管理**（`secret.go`）：多来源 API 密钥解析并带缓存
+5. **主模块**（`amp.go`）：负责注册和配置
+
+## 配置
+
+### 基础配置
+
+在 `config.yaml` 中新增以下字段：
+
+```yaml
+# Amp 上游控制平面（管理路由必需）
+amp-upstream-url: "https://ampcode.com"
+
+# 可选：覆盖 API key（否则使用环境变量或文件）
+# amp-upstream-api-key: "your-amp-api-key"
+
+# 安全性：将管理路由限制为 localhost（推荐）
+amp-restrict-management-to-localhost: true
+```
+
+### 密钥解析优先级
+
+Amp 模块以如下优先级解析 API key：
+
+| 来源 | 键名 | 优先级 | 缓存 |
+|------|------|--------|------|
+| 配置文件 | `amp-upstream-api-key` | 高 | 无 |
+| 环境变量 | `AMP_API_KEY` | 中 | 无 |
+| Amp 密钥文件 | `~/.local/share/amp/secrets.json` | 低 | 5 分钟 |
+
+**建议**：日常使用时采用 Amp 密钥文件（最低优先级）。该文件由 `amp login` 自动管理。
+
+### 安全设置
+
+**`amp-restrict-management-to-localhost`**（默认：`true`）
+
+启用后，管理路由（`/api/auth`、`/api/user`、`/api/threads` 等）只接受来自 localhost（127.0.0.1、::1）的连接，可防止：
+- 浏览器探测式攻击
+- 对管理端点的远程访问
+- 基于 CORS 的攻击
+- 伪造头攻击（例如 `X-Forwarded-For: 127.0.0.1`）
+
+#### 工作原理
+
+此限制使用**实际的 TCP 连接地址**（`RemoteAddr`），而非 `X-Forwarded-For` 等 HTTP 头，能防止头部伪造，但有重要影响：
+
+- ✅ **直接连接可用**：在本机或服务器直接运行 CLIProxyAPI 时适用
+- ⚠️ **可能不适用于反向代理场景**：部署在 nginx、Cloudflare 等代理后，请求源会显示为代理 IP 而非 localhost
+
+#### 反向代理部署
+
+若需要在反向代理（nginx、Caddy、Cloudflare Tunnel 等）后运行 CLIProxyAPI：
+
+1. **关闭 localhost 限制**：
+   ```yaml
+   amp-restrict-management-to-localhost: false
+   ```
+
+2. **使用替代安全措施**：
+   - 防火墙规则限制管理路由访问
+   - 代理层认证（HTTP Basic Auth、OAuth）
+   - 网络隔离（VPN、Tailscale、Cloudflare Access）
+   - 将 CLIProxyAPI 仅绑定 `127.0.0.1`，并通过 SSH 隧道访问
+
+3. **nginx 示例配置**（阻止外部访问管理路由）：
+   ```nginx
+   location /api/auth { deny all; }
+   location /api/user { deny all; }
+   location /api/threads { deny all; }
+   location /api/internal { deny all; }
+   ```
+
+**重要**：只有在理解安全影响并已采取其他防护措施时，才关闭 `amp-restrict-management-to-localhost`。
+
+## 设置
+
+### 1. 配置 CLIProxyAPI
+
+创建或编辑 `config.yaml`：
+
+```yaml
+port: 8317
+auth-dir: "~/.cli-proxy-api"
+
+# Amp 集成
+amp-upstream-url: "https://ampcode.com"
+amp-restrict-management-to-localhost: true
+
+# 其他常规设置...
+debug: false
+logging-to-file: true
+```
+
+### 2. 认证提供商
+
+为要使用的提供商执行 OAuth 登录：
+
+**Google 账号（Gemini 2.5 Pro、Gemini 2.5 Flash、Gemini 3 Pro Preview）：**
+```bash
+./cli-proxy-api --login
+```
+
+**ChatGPT Plus/Pro（GPT-5、GPT-5 Codex）：**
+```bash
+./cli-proxy-api --codex-login
+```
+
+**Claude Pro/Max（Claude Sonnet 4.5、Opus 4.1）：**
+```bash
+./cli-proxy-api --claude-login
+```
+
+令牌会保存到：
+- Gemini: `~/.cli-proxy-api/gemini-<email>.json`
+- OpenAI Codex: `~/.cli-proxy-api/codex-<email>.json`
+- Claude: `~/.cli-proxy-api/claude-<email>.json`
+
+### 3. 启动代理
+
+```bash
+./cli-proxy-api --config config.yaml
+```
+
+或使用 tmux 在后台运行（推荐用于远程服务器）：
+
+```bash
+tmux new-session -d -s proxy "./cli-proxy-api --config config.yaml"
+```
+
+### 4. 配置 Amp CLI
+
+#### 方案 A：配置文件
+
+编辑 `~/.config/amp/settings.json`：
+
+```json
+{
+  "amp.url": "http://localhost:8317"
+}
+```
+
+#### 方案 B：环境变量
+
+```bash
+export AMP_URL=http://localhost:8317
+```
+
+### 5. 登录并使用 Amp
+
+通过代理登录（请求会被代理到 ampcode.com）：
+
+```bash
+amp login
+```
+
+像平常一样使用 Amp：
+
+```bash
+amp "Write a hello world program in Python"
+```
+
+### 6. （可选）配置 Amp IDE 扩展
+
+该代理同样适用于 VS Code、Cursor、Windsurf 等 Amp IDE 扩展。
+
+1. 在 IDE 中打开 Amp 扩展设置
+2. 将 **Amp URL** 设置为 `http://localhost:8317`
+3. 用你的 Amp 账号登录
+4. 在 IDE 中开始使用 Amp
+
+CLI 和 IDE 可同时使用该代理。
+
+## 用法
+
+### 支持的路由
+
+#### 提供商别名（始终可用）
+
+这些路由即使未配置 `amp-upstream-url` 也可使用：
+
+- `/api/provider/openai/v1/chat/completions`
+- `/api/provider/openai/v1/responses`
+- `/api/provider/anthropic/v1/messages`
+- `/api/provider/google/v1beta/models/:action`
+
+Amp CLI 会使用你在 CLIProxyAPI 中通过 OAuth 认证的模型来调用这些路由。
+
+#### 管理路由（需要 `amp-upstream-url`）
+
+这些路由会被代理到 ampcode.com：
+
+- `/api/auth` - 认证
+- `/api/user` - 用户资料
+- `/api/meta` - 元数据
+- `/api/threads` - 会话线程
+- `/api/telemetry` - 使用遥测
+- `/api/internal` - 内部 API
+
+**安全性**：默认限制为 localhost。
+
+### 模型回退行为
+
+当 Amp 请求模型时：
+
+1. **检查本地配置**：CLIProxyAPI 是否有该模型提供商的 OAuth 令牌？
+2. **如果有**：路由到本地处理器（使用你的 OAuth 订阅）
+3. **如果没有**：转发到 ampcode.com（使用 Amp 的默认路由）
+
+这实现了无缝混用：
+- 你已配置的模型（Gemini、ChatGPT、Claude）→ 你的 OAuth 订阅
+- 未配置的模型 → Amp 的默认提供商
+
+### 示例 API 调用
+
+**使用本地 OAuth 的聊天补全：**
+```bash
+curl http://localhost:8317/api/provider/openai/v1/chat/completions \
+  -H "Content-Type: application/json" \
+  -d '{
+    "model": "gpt-5",
+    "messages": [{"role": "user", "content": "Hello"}]
+  }'
+```
+
+**管理端点（仅限 localhost）：**
+```bash
+curl http://localhost:8317/api/user
+```
+
+## 故障排查
+
+### 常见问题
+
+| 症状 | 可能原因 | 解决方案 |
+|------|----------|----------|
+| `/api/provider/...` 返回 404 | 路径错误 | 确保路径准确：`/api/provider/{provider}/v1...` |
+| `/api/user` 返回 403 | 非 localhost 请求 | 在同一机器上访问，或关闭 `amp-restrict-management-to-localhost`（不推荐） |
+| 提供商返回 401/403 | OAuth 缺失或过期 | 重新运行 `--codex-login` 或 `--claude-login` |
+| Amp gzip 错误 | 响应解压问题 | 更新到最新构建；自动解压应能处理 |
+| 模型未走代理 | Amp URL 设置错误 | 检查 `amp.url` 设置或 `AMP_URL` 环境变量 |
+| CORS 错误 | 受保护的管理端点 | 使用 CLI/终端而非浏览器 |
+
+### 诊断
+
+**查看代理日志：**
+```bash
+# 若 logging-to-file: true
+tail -f logs/requests.log
+
+# 若运行在 tmux 中
+tmux attach-session -t proxy
+```
+
+**临时开启调试模式：**
+```yaml
+debug: true
+```
+
+**测试基础连通性：**
+```bash
+# 检查代理是否运行
+curl http://localhost:8317/v1/models
+
+# 检查 Amp 特定路由
+curl http://localhost:8317/api/provider/openai/v1/models
+```
+
+**验证 Amp 配置：**
+```bash
+# 检查 Amp 是否使用代理
+amp config get amp.url
+
+# 或检查环境变量
+echo $AMP_URL
+```
+
+### 安全清单
+
+- ✅ 保持 `amp-restrict-management-to-localhost: true`（默认）
+- ✅ 不要将代理暴露到公共网络（绑定到 localhost 或使用防火墙/VPN）
+- ✅ 使用 `amp login` 管理的 Amp 密钥文件（`~/.local/share/amp/secrets.json`）
+- ✅ 定期重新登录轮换 OAuth 令牌
+- ✅ 若处理敏感数据，使用加密磁盘存储配置和 auth-dir
+- ✅ 保持代理二进制为最新版本以获取安全修复

+# @sdk/access SDK Reference
+
+The `github.com/router-for-me/CLIProxyAPI/v6/sdk/access` package centralizes inbound request authentication for the proxy. It offers a lightweight manager that chains credential providers, so servers can reuse the same access control logic inside or outside the CLI runtime.
+
+## Importing
+
+```go
+import (
+    sdkaccess "github.com/router-for-me/CLIProxyAPI/v6/sdk/access"
+    "github.com/router-for-me/CLIProxyAPI/v6/internal/config"
+)
+```
+
+Add the module with `go get github.com/router-for-me/CLIProxyAPI/v6/sdk/access`.
+
+## Manager Lifecycle
+
+```go
+manager := sdkaccess.NewManager()
+providers, err := sdkaccess.BuildProviders(cfg)
+if err != nil {
+    return err
+}
+manager.SetProviders(providers)
+```
+
+* `NewManager` constructs an empty manager.
+* `SetProviders` replaces the provider slice using a defensive copy.
+* `Providers` retrieves a snapshot that can be iterated safely from other goroutines.
+* `BuildProviders` translates `config.Config` access declarations into runnable providers. When the config omits explicit providers but defines inline API keys, the helper auto-installs the built-in `config-api-key` provider.
+
+## Authenticating Requests
+
+```go
+result, err := manager.Authenticate(ctx, req)
+switch {
+case err == nil:
+    // Authentication succeeded; result describes the provider and principal.
+case errors.Is(err, sdkaccess.ErrNoCredentials):
+    // No recognizable credentials were supplied.
+case errors.Is(err, sdkaccess.ErrInvalidCredential):
+    // Supplied credentials were present but rejected.
+default:
+    // Transport-level failure was returned by a provider.
+}
+```
+
+`Manager.Authenticate` walks the configured providers in order. It returns on the first success, skips providers that surface `ErrNotHandled`, and tracks whether any provider reported `ErrNoCredentials` or `ErrInvalidCredential` for downstream error reporting.
+
+If the manager itself is `nil` or no providers are registered, the call returns `nil, nil`, allowing callers to treat access control as disabled without branching on errors.
+
+Each `Result` includes the provider identifier, the resolved principal, and optional metadata (for example, which header carried the credential).
+
+## Configuration Layout
+
+The manager expects access providers under the `auth.providers` key inside `config.yaml`:
+
+```yaml
+auth:
+  providers:
+    - name: inline-api
+      type: config-api-key
+      api-keys:
+        - sk-test-123
+        - sk-prod-456
+```
+
+Fields map directly to `config.AccessProvider`: `name` labels the provider, `type` selects the registered factory, `sdk` can name an external module, `api-keys` seeds inline credentials, and `config` passes provider-specific options.
+
+### Loading providers from external SDK modules
+
+To consume a provider shipped in another Go module, point the `sdk` field at the module path and import it for its registration side effect:
+
+```yaml
+auth:
+  providers:
+    - name: partner-auth
+      type: partner-token
+      sdk: github.com/acme/xplatform/sdk/access/providers/partner
+      config:
+        region: us-west-2
+        audience: cli-proxy
+```
+
+```go
+import (
+    _ "github.com/acme/xplatform/sdk/access/providers/partner" // registers partner-token
+    sdkaccess "github.com/router-for-me/CLIProxyAPI/v6/sdk/access"
+)
+```
+
+The blank identifier import ensures `init` runs so `sdkaccess.RegisterProvider` executes before `BuildProviders` is called.
+
+## Built-in Providers
+
+The SDK ships with one provider out of the box:
+
+- `config-api-key`: Validates API keys declared inline or under top-level `api-keys`. It accepts the key from `Authorization: Bearer`, `X-Goog-Api-Key`, `X-Api-Key`, or the `?key=` query string and reports `ErrInvalidCredential` when no match is found.
+
+Additional providers can be delivered by third-party packages. When a provider package is imported, it registers itself with `sdkaccess.RegisterProvider`.
+
+### Metadata and auditing
+
+`Result.Metadata` carries provider-specific context. The built-in `config-api-key` provider, for example, stores the credential source (`authorization`, `x-goog-api-key`, `x-api-key`, or `query-key`). Populate this map in custom providers to enrich logs and downstream auditing.
+
+## Writing Custom Providers
+
+```go
+type customProvider struct{}
+
+func (p *customProvider) Identifier() string { return "my-provider" }
+
+func (p *customProvider) Authenticate(ctx context.Context, r *http.Request) (*sdkaccess.Result, error) {
+    token := r.Header.Get("X-Custom")
+    if token == "" {
+        return nil, sdkaccess.ErrNoCredentials
+    }
+    if token != "expected" {
+        return nil, sdkaccess.ErrInvalidCredential
+    }
+    return &sdkaccess.Result{
+        Provider:  p.Identifier(),
+        Principal: "service-user",
+        Metadata:  map[string]string{"source": "x-custom"},
+    }, nil
+}
+
+func init() {
+    sdkaccess.RegisterProvider("custom", func(cfg *config.AccessProvider, root *config.Config) (sdkaccess.Provider, error) {
+        return &customProvider{}, nil
+    })
+}
+```
+
+A provider must implement `Identifier()` and `Authenticate()`. To expose it to configuration, call `RegisterProvider` inside `init`. Provider factories receive the specific `AccessProvider` block plus the full root configuration for contextual needs.
+
+## Error Semantics
+
+- `ErrNoCredentials`: no credentials were present or recognized by any provider.
+- `ErrInvalidCredential`: at least one provider processed the credentials but rejected them.
+- `ErrNotHandled`: instructs the manager to fall through to the next provider without affecting aggregate error reporting.
+
+Return custom errors to surface transport failures; they propagate immediately to the caller instead of being masked.
+
+## Integration with cliproxy Service
+
+`sdk/cliproxy` wires `@sdk/access` automatically when you build a CLI service via `cliproxy.NewBuilder`. Supplying a preconfigured manager allows you to extend or override the default providers:
+
+```go
+coreCfg, _ := config.LoadConfig("config.yaml")
+providers, _ := sdkaccess.BuildProviders(coreCfg)
+manager := sdkaccess.NewManager()
+manager.SetProviders(providers)
+
+svc, _ := cliproxy.NewBuilder().
+  WithConfig(coreCfg).
+  WithAccessManager(manager).
+  Build()
+```
+
+The service reuses the manager for every inbound request, ensuring consistent authentication across embedded deployments and the canonical CLI binary.
+
+### Hot reloading providers
+
+When configuration changes, rebuild providers and swap them into the manager:
+
+```go
+providers, err := sdkaccess.BuildProviders(newCfg)
+if err != nil {
+    log.Errorf("reload auth providers failed: %v", err)
+    return
+}
+accessManager.SetProviders(providers)
+```
+
+This mirrors the behaviour in `cliproxy.Service.refreshAccessProviders` and `api.Server.applyAccessConfig`, enabling runtime updates without restarting the process.

+# @sdk/access 开发指引
+
+`github.com/router-for-me/CLIProxyAPI/v6/sdk/access` 包负责代理的入站访问认证。它提供一个轻量的管理器，用于按顺序链接多种凭证校验实现，让服务器在 CLI 运行时内外都能复用相同的访问控制逻辑。
+
+## 引用方式
+
+```go
+import (
+    sdkaccess "github.com/router-for-me/CLIProxyAPI/v6/sdk/access"
+    "github.com/router-for-me/CLIProxyAPI/v6/internal/config"
+)
+```
+
+通过 `go get github.com/router-for-me/CLIProxyAPI/v6/sdk/access` 添加依赖。
+
+## 管理器生命周期
+
+```go
+manager := sdkaccess.NewManager()
+providers, err := sdkaccess.BuildProviders(cfg)
+if err != nil {
+    return err
+}
+manager.SetProviders(providers)
+```
+
+- `NewManager` 创建空管理器。
+- `SetProviders` 替换提供者切片并做防御性拷贝。
+- `Providers` 返回适合并发读取的快照。
+- `BuildProviders` 将 `config.Config` 中的访问配置转换成可运行的提供者。当配置没有显式声明但包含顶层 `api-keys` 时，会自动挂载内建的 `config-api-key` 提供者。
+
+## 认证请求
+
+```go
+result, err := manager.Authenticate(ctx, req)
+switch {
+case err == nil:
+    // Authentication succeeded; result carries provider and principal.
+case errors.Is(err, sdkaccess.ErrNoCredentials):
+    // No recognizable credentials were supplied.
+case errors.Is(err, sdkaccess.ErrInvalidCredential):
+    // Credentials were present but rejected.
+default:
+    // Provider surfaced a transport-level failure.
+}
+```
+
+`Manager.Authenticate` 按配置顺序遍历提供者。遇到成功立即返回，`ErrNotHandled` 会继续尝试下一个；若发现 `ErrNoCredentials` 或 `ErrInvalidCredential`，会在遍历结束后汇总给调用方。
+
+若管理器本身为 `nil` 或尚未注册提供者，调用会返回 `nil, nil`，让调用方无需针对错误做额外分支即可关闭访问控制。
+
+`Result` 提供认证提供者标识、解析出的主体以及可选元数据（例如凭证来源）。
+
+## 配置结构
+
+在 `config.yaml` 的 `auth.providers` 下定义访问提供者：
+
+```yaml
+auth:
+  providers:
+    - name: inline-api
+      type: config-api-key
+      api-keys:
+        - sk-test-123
+        - sk-prod-456
+```
+
+条目映射到 `config.AccessProvider`：`name` 指定实例名，`type` 选择注册的工厂，`sdk` 可引用第三方模块，`api-keys` 提供内联凭证，`config` 用于传递特定选项。
+
+### 引入外部 SDK 提供者
+
+若要消费其它 Go 模块输出的访问提供者，可在配置里填写 `sdk` 字段并在代码中引入该包，利用其 `init` 注册过程：
+
+```yaml
+auth:
+  providers:
+    - name: partner-auth
+      type: partner-token
+      sdk: github.com/acme/xplatform/sdk/access/providers/partner
+      config:
+        region: us-west-2
+        audience: cli-proxy
+```
+
+```go
+import (
+    _ "github.com/acme/xplatform/sdk/access/providers/partner" // registers partner-token
+    sdkaccess "github.com/router-for-me/CLIProxyAPI/v6/sdk/access"
+)
+```
+
+通过空白标识符导入即可确保 `init` 调用，先于 `BuildProviders` 完成 `sdkaccess.RegisterProvider`。
+
+## 内建提供者
+
+当前 SDK 默认内置：
+
+- `config-api-key`：校验配置中的 API Key。它从 `Authorization: Bearer`、`X-Goog-Api-Key`、`X-Api-Key` 以及查询参数 `?key=` 提取凭证，不匹配时抛出 `ErrInvalidCredential`。
+
+导入第三方包即可通过 `sdkaccess.RegisterProvider` 注册更多类型。
+
+### 元数据与审计
+
+`Result.Metadata` 用于携带提供者特定的上下文信息。内建的 `config-api-key` 会记录凭证来源（`authorization`、`x-goog-api-key`、`x-api-key` 或 `query-key`）。自定义提供者同样可以填充该 Map，以便丰富日志与审计场景。
+
+## 编写自定义提供者
+
+```go
+type customProvider struct{}
+
+func (p *customProvider) Identifier() string { return "my-provider" }
+
+func (p *customProvider) Authenticate(ctx context.Context, r *http.Request) (*sdkaccess.Result, error) {
+    token := r.Header.Get("X-Custom")
+    if token == "" {
+        return nil, sdkaccess.ErrNoCredentials
+    }
+    if token != "expected" {
+        return nil, sdkaccess.ErrInvalidCredential
+    }
+    return &sdkaccess.Result{
+        Provider:  p.Identifier(),
+        Principal: "service-user",
+        Metadata:  map[string]string{"source": "x-custom"},
+    }, nil
+}
+
+func init() {
+    sdkaccess.RegisterProvider("custom", func(cfg *config.AccessProvider, root *config.Config) (sdkaccess.Provider, error) {
+        return &customProvider{}, nil
+    })
+}
+```
+
+自定义提供者需要实现 `Identifier()` 与 `Authenticate()`。在 `init` 中调用 `RegisterProvider` 暴露给配置层，工厂函数既能读取当前条目，也能访问完整根配置。
+
+## 错误语义
+
+- `ErrNoCredentials`：任何提供者都未识别到凭证。
+- `ErrInvalidCredential`：至少一个提供者处理了凭证但判定无效。
+- `ErrNotHandled`：告诉管理器跳到下一个提供者，不影响最终错误统计。
+
+自定义错误（例如网络异常）会马上冒泡返回。
+
+## 与 cliproxy 集成
+
+使用 `sdk/cliproxy` 构建服务时会自动接入 `@sdk/access`。如果需要扩展内置行为，可传入自定义管理器：
+
+```go
+coreCfg, _ := config.LoadConfig("config.yaml")
+providers, _ := sdkaccess.BuildProviders(coreCfg)
+manager := sdkaccess.NewManager()
+manager.SetProviders(providers)
+
+svc, _ := cliproxy.NewBuilder().
+  WithConfig(coreCfg).
+  WithAccessManager(manager).
+  Build()
+```
+
+服务会复用该管理器处理每一个入站请求，实现与 CLI 二进制一致的访问控制体验。
+
+### 动态热更新提供者
+
+当配置发生变化时，可以重新构建提供者并替换当前列表：
+
+```go
+providers, err := sdkaccess.BuildProviders(newCfg)
+if err != nil {
+    log.Errorf("reload auth providers failed: %v", err)
+    return
+}
+accessManager.SetProviders(providers)
+```
+
+这一流程与 `cliproxy.Service.refreshAccessProviders` 和 `api.Server.applyAccessConfig` 保持一致，避免为更新访问策略而重启进程。

+# SDK Advanced: Executors & Translators
+
+This guide explains how to extend the embedded proxy with custom providers and schemas using the SDK. You will:
+- Implement a provider executor that talks to your upstream API
+- Register request/response translators for schema conversion
+- Register models so they appear in `/v1/models`
+
+The examples use Go 1.24+ and the v6 module path.
+
+## Concepts
+
+- Provider executor: a runtime component implementing `auth.ProviderExecutor` that performs outbound calls for a given provider key (e.g., `gemini`, `claude`, `codex`). Executors can also implement `RequestPreparer` to inject credentials on raw HTTP requests.
+- Translator registry: schema conversion functions routed by `sdk/translator`. The built‑in handlers translate between OpenAI/Gemini/Claude/Codex formats; you can register new ones.
+- Model registry: publishes the list of available models per client/provider to power `/v1/models` and routing hints.
+
+## 1) Implement a Provider Executor
+
+Create a type that satisfies `auth.ProviderExecutor`.
+
+```go
+package myprov
+
+import (
+  "context"
+  "net/http"
+
+  coreauth "github.com/router-for-me/CLIProxyAPI/v6/sdk/cliproxy/auth"
+  clipexec "github.com/router-for-me/CLIProxyAPI/v6/sdk/cliproxy/executor"
+)
+
+type Executor struct{}
+
+func (Executor) Identifier() string { return "myprov" }
+
+// Optional: mutate outbound HTTP requests with credentials
+func (Executor) PrepareRequest(req *http.Request, a *coreauth.Auth) error {
+  // Example: req.Header.Set("Authorization", "Bearer "+a.APIKey)
+  return nil
+}
+
+func (Executor) Execute(ctx context.Context, a *coreauth.Auth, req clipexec.Request, opts clipexec.Options) (clipexec.Response, error) {
+  // Build HTTP request based on req.Payload (already translated into provider format)
+  // Use per‑auth transport if provided: transport := a.RoundTripper // via RoundTripperProvider
+  // Perform call and return provider JSON payload
+  return clipexec.Response{Payload: []byte(`{"ok":true}`)}, nil
+}
+
+func (Executor) ExecuteStream(ctx context.Context, a *coreauth.Auth, req clipexec.Request, opts clipexec.Options) (<-chan clipexec.StreamChunk, error) {
+  ch := make(chan clipexec.StreamChunk, 1)
+  go func() { defer close(ch); ch <- clipexec.StreamChunk{Payload: []byte("data: {\"done\":true}\n\n")} }()
+  return ch, nil
+}
+
+func (Executor) Refresh(ctx context.Context, a *coreauth.Auth) (*coreauth.Auth, error) {
+  // Optionally refresh tokens and return updated auth
+  return a, nil
+}
+```
+
+Register the executor with the core manager before starting the service:
+
+```go
+core := coreauth.NewManager(coreauth.NewFileStore(cfg.AuthDir), nil, nil)
+core.RegisterExecutor(myprov.Executor{})
+svc, _ := cliproxy.NewBuilder().WithConfig(cfg).WithConfigPath(cfgPath).WithCoreAuthManager(core).Build()
+```
+
+If your auth entries use provider `"myprov"`, the manager routes requests to your executor.
+
+## 2) Register Translators
+
+The handlers accept OpenAI/Gemini/Claude/Codex inputs. To support a new provider format, register translation functions in `sdk/translator`’s default registry.
+
+Direction matters:
+- Request: register from inbound schema to provider schema
+- Response: register from provider schema back to inbound schema
+
+Example: Convert OpenAI Chat → MyProv Chat and back.
+
+```go
+package myprov
+
+import (
+  "context"
+  sdktr "github.com/router-for-me/CLIProxyAPI/v6/sdk/translator"
+)
+
+const (
+  FOpenAI = sdktr.Format("openai.chat")
+  FMyProv = sdktr.Format("myprov.chat")
+)
+
+func init() {
+  sdktr.Register(FOpenAI, FMyProv,
+    // Request transform (model, rawJSON, stream)
+    func(model string, raw []byte, stream bool) []byte { return convertOpenAIToMyProv(model, raw, stream) },
+    // Response transform (stream & non‑stream)
+    sdktr.ResponseTransform{
+      Stream: func(ctx context.Context, model string, originalReq, translatedReq, raw []byte, param *any) []string {
+        return convertStreamMyProvToOpenAI(model, originalReq, translatedReq, raw)
+      },
+      NonStream: func(ctx context.Context, model string, originalReq, translatedReq, raw []byte, param *any) string {
+        return convertMyProvToOpenAI(model, originalReq, translatedReq, raw)
+      },
+    },
+  )
+}
+```
+
+When the OpenAI handler receives a request that should route to `myprov`, the pipeline uses the registered transforms automatically.
+
+## 3) Register Models
+
+Expose models under `/v1/models` by registering them in the global model registry using the auth ID (client ID) and provider name.
+
+```go
+models := []*cliproxy.ModelInfo{
+  { ID: "myprov-pro-1", Object: "model", Type: "myprov", DisplayName: "MyProv Pro 1" },
+}
+cliproxy.GlobalModelRegistry().RegisterClient(authID, "myprov", models)
+```
+
+The embedded server calls this automatically for built‑in providers; for custom providers, register during startup (e.g., after loading auths) or upon auth registration hooks.
+
+## Credentials & Transports
+
+- Use `Manager.SetRoundTripperProvider` to inject per‑auth `*http.Transport` (e.g., proxy):
+  ```go
+  core.SetRoundTripperProvider(myProvider) // returns transport per auth
+  ```
+- For raw HTTP flows, implement `PrepareRequest` and/or call `Manager.InjectCredentials(req, authID)` to set headers.
+
+## Testing Tips
+
+- Enable request logging: Management API GET/PUT `/v0/management/request-log`
+- Toggle debug logs: Management API GET/PUT `/v0/management/debug`
+- Hot reload changes in `config.yaml` and `auths/` are picked up automatically by the watcher

+# SDK 高级指南：执行器与翻译器
+
+本文介绍如何使用 SDK 扩展内嵌代理：
+- 实现自定义 Provider 执行器以调用你的上游 API
+- 注册请求/响应翻译器进行协议转换
+- 注册模型以出现在 `/v1/models`
+
+示例基于 Go 1.24+ 与 v6 模块路径。
+
+## 概念
+
+- Provider 执行器：实现 `auth.ProviderExecutor` 的运行时组件，负责某个 provider key（如 `gemini`、`claude`、`codex`）的真正出站调用。若实现 `RequestPreparer` 接口，可在原始 HTTP 请求上注入凭据。
+- 翻译器注册表：由 `sdk/translator` 驱动的协议转换函数。内置了 OpenAI/Gemini/Claude/Codex 的互转；你也可以注册新的格式转换。
+- 模型注册表：对外发布可用模型列表，供 `/v1/models` 与路由参考。
+
+## 1) 实现 Provider 执行器
+
+创建类型满足 `auth.ProviderExecutor` 接口。
+
+```go
+package myprov
+
+import (
+    "context"
+    "net/http"
+
+    coreauth "github.com/router-for-me/CLIProxyAPI/v6/sdk/cliproxy/auth"
+    clipexec "github.com/router-for-me/CLIProxyAPI/v6/sdk/cliproxy/executor"
+)
+
+type Executor struct{}
+
+func (Executor) Identifier() string { return "myprov" }
+
+// 可选：在原始 HTTP 请求上注入凭据
+func (Executor) PrepareRequest(req *http.Request, a *coreauth.Auth) error {
+    // 例如：req.Header.Set("Authorization", "Bearer "+a.Attributes["api_key"]) 
+    return nil
+}
+
+func (Executor) Execute(ctx context.Context, a *coreauth.Auth, req clipexec.Request, opts clipexec.Options) (clipexec.Response, error) {
+    // 基于 req.Payload 构造上游请求，返回上游 JSON 负载
+    return clipexec.Response{Payload: []byte(`{"ok":true}`)}, nil
+}
+
+func (Executor) ExecuteStream(ctx context.Context, a *coreauth.Auth, req clipexec.Request, opts clipexec.Options) (<-chan clipexec.StreamChunk, error) {
+    ch := make(chan clipexec.StreamChunk, 1)
+    go func() { defer close(ch); ch <- clipexec.StreamChunk{Payload: []byte("data: {\\"done\\":true}\\n\\n")} }()
+    return ch, nil
+}
+
+func (Executor) Refresh(ctx context.Context, a *coreauth.Auth) (*coreauth.Auth, error) { return a, nil }
+```
+
+在启动服务前将执行器注册到核心管理器：
+
+```go
+core := coreauth.NewManager(coreauth.NewFileStore(cfg.AuthDir), nil, nil)
+core.RegisterExecutor(myprov.Executor{})
+svc, _ := cliproxy.NewBuilder().WithConfig(cfg).WithConfigPath(cfgPath).WithCoreAuthManager(core).Build()
+```
+
+当凭据的 `Provider` 为 `"myprov"` 时，管理器会将请求路由到你的执行器。
+
+## 2) 注册翻译器
+
+内置处理器接受 OpenAI/Gemini/Claude/Codex 的入站格式。要支持新的 provider 协议，需要在 `sdk/translator` 的默认注册表中注册转换函数。
+
+方向很重要：
+- 请求：从“入站格式”转换为“provider 格式”
+- 响应：从“provider 格式”转换回“入站格式”
+
+示例：OpenAI Chat → MyProv Chat 及其反向。
+
+```go
+package myprov
+
+import (
+  "context"
+  sdktr "github.com/router-for-me/CLIProxyAPI/v6/sdk/translator"
+)
+
+const (
+  FOpenAI = sdktr.Format("openai.chat")
+  FMyProv = sdktr.Format("myprov.chat")
+)
+
+func init() {
+  sdktr.Register(FOpenAI, FMyProv,
+    func(model string, raw []byte, stream bool) []byte { return convertOpenAIToMyProv(model, raw, stream) },
+    sdktr.ResponseTransform{
+      Stream: func(ctx context.Context, model string, originalReq, translatedReq, raw []byte, param *any) []string {
+        return convertStreamMyProvToOpenAI(model, originalReq, translatedReq, raw)
+      },
+      NonStream: func(ctx context.Context, model string, originalReq, translatedReq, raw []byte, param *any) string {
+        return convertMyProvToOpenAI(model, originalReq, translatedReq, raw)
+      },
+    },
+  )
+}
+```
+
+当 OpenAI 处理器接到需要路由到 `myprov` 的请求时，流水线会自动应用已注册的转换。
+
+## 3) 注册模型
+
+通过全局模型注册表将模型暴露到 `/v1/models`：
+
+```go
+models := []*cliproxy.ModelInfo{
+  { ID: "myprov-pro-1", Object: "model", Type: "myprov", DisplayName: "MyProv Pro 1" },
+}
+cliproxy.GlobalModelRegistry().RegisterClient(authID, "myprov", models)
+```
+
+内置 Provider 会自动注册；自定义 Provider 建议在启动时（例如加载到 Auth 后）或在 Auth 注册钩子中调用。
+
+## 凭据与传输
+
+- 使用 `Manager.SetRoundTripperProvider` 注入按账户的 `*http.Transport`（例如代理）：
+  ```go
+  core.SetRoundTripperProvider(myProvider) // 按账户返回 transport
+  ```
+- 对于原始 HTTP 请求，若实现了 `PrepareRequest`，或通过 `Manager.InjectCredentials(req, authID)` 进行头部注入。
+
+## 测试建议
+
+- 启用请求日志：管理 API GET/PUT `/v0/management/request-log`
+- 切换调试日志：管理 API GET/PUT `/v0/management/debug`
+- 热更新：`config.yaml` 与 `auths/` 变化会自动被侦测并应用

+# CLI Proxy SDK Guide
+
+The `sdk/cliproxy` module exposes the proxy as a reusable Go library so external programs can embed the routing, authentication, hot‑reload, and translation layers without depending on the CLI binary.
+
+## Install & Import
+
+```bash
+go get github.com/router-for-me/CLIProxyAPI/v6/sdk/cliproxy
+```
+
+```go
+import (
+    "context"
+    "errors"
+    "time"
+
+    "github.com/router-for-me/CLIProxyAPI/v6/internal/config"
+    "github.com/router-for-me/CLIProxyAPI/v6/sdk/cliproxy"
+)
+```
+
+Note the `/v6` module path.
+
+## Minimal Embed
+
+```go
+cfg, err := config.LoadConfig("config.yaml")
+if err != nil { panic(err) }
+
+svc, err := cliproxy.NewBuilder().
+    WithConfig(cfg).
+    WithConfigPath("config.yaml"). // absolute or working-dir relative
+    Build()
+if err != nil { panic(err) }
+
+ctx, cancel := context.WithCancel(context.Background())
+defer cancel()
+
+if err := svc.Run(ctx); err != nil && !errors.Is(err, context.Canceled) {
+    panic(err)
+}
+```
+
+The service manages config/auth watching, background token refresh, and graceful shutdown. Cancel the context to stop it.
+
+## Server Options (middleware, routes, logs)
+
+The server accepts options via `WithServerOptions`:
+
+```go
+svc, _ := cliproxy.NewBuilder().
+  WithConfig(cfg).
+  WithConfigPath("config.yaml").
+  WithServerOptions(
+    // Add global middleware
+    cliproxy.WithMiddleware(func(c *gin.Context) { c.Header("X-Embed", "1"); c.Next() }),
+    // Tweak gin engine early (CORS, trusted proxies, etc.)
+    cliproxy.WithEngineConfigurator(func(e *gin.Engine) { e.ForwardedByClientIP = true }),
+    // Add your own routes after defaults
+    cliproxy.WithRouterConfigurator(func(e *gin.Engine, _ *handlers.BaseAPIHandler, _ *config.Config) {
+      e.GET("/healthz", func(c *gin.Context) { c.String(200, "ok") })
+    }),
+    // Override request log writer/dir
+    cliproxy.WithRequestLoggerFactory(func(cfg *config.Config, cfgPath string) logging.RequestLogger {
+      return logging.NewFileRequestLogger(true, "logs", filepath.Dir(cfgPath))
+    }),
+  ).
+  Build()
+```
+
+These options mirror the internals used by the CLI server.
+
+## Management API (when embedded)
+
+- Management endpoints are mounted only when `remote-management.secret-key` is set in `config.yaml`.
+- Remote access additionally requires `remote-management.allow-remote: true`.
+- See MANAGEMENT_API.md for endpoints. Your embedded server exposes them under `/v0/management` on the configured port.
+
+## Using the Core Auth Manager
+
+The service uses a core `auth.Manager` for selection, execution, and auto‑refresh. When embedding, you can provide your own manager to customize transports or hooks:
+
+```go
+core := coreauth.NewManager(coreauth.NewFileStore(cfg.AuthDir), nil, nil)
+core.SetRoundTripperProvider(myRTProvider) // per‑auth *http.Transport
+
+svc, _ := cliproxy.NewBuilder().
+    WithConfig(cfg).
+    WithConfigPath("config.yaml").
+    WithCoreAuthManager(core).
+    Build()
+```
+
+Implement a custom per‑auth transport:
+
+```go
+type myRTProvider struct{}
+func (myRTProvider) RoundTripperFor(a *coreauth.Auth) http.RoundTripper {
+    if a == nil || a.ProxyURL == "" { return nil }
+    u, _ := url.Parse(a.ProxyURL)
+    return &http.Transport{ Proxy: http.ProxyURL(u) }
+}
+```
+
+Programmatic execution is available on the manager:
+
+```go
+// Non‑streaming
+resp, err := core.Execute(ctx, []string{"gemini"}, req, opts)
+
+// Streaming
+chunks, err := core.ExecuteStream(ctx, []string{"gemini"}, req, opts)
+for ch := range chunks { /* ... */ }
+```
+
+Note: Built‑in provider executors are wired automatically when you run the `Service`. If you want to use `Manager` stand‑alone without the HTTP server, you must register your own executors that implement `auth.ProviderExecutor`.
+
+## Custom Client Sources
+
+Replace the default loaders if your creds live outside the local filesystem:
+
+```go
+type memoryTokenProvider struct{}
+func (p *memoryTokenProvider) Load(ctx context.Context, cfg *config.Config) (*cliproxy.TokenClientResult, error) {
+    // Populate from memory/remote store and return counts
+    return &cliproxy.TokenClientResult{}, nil
+}
+
+svc, _ := cliproxy.NewBuilder().
+  WithConfig(cfg).
+  WithConfigPath("config.yaml").
+  WithTokenClientProvider(&memoryTokenProvider{}).
+  WithAPIKeyClientProvider(cliproxy.NewAPIKeyClientProvider()).
+  Build()
+```
+
+## Hooks
+
+Observe lifecycle without patching internals:
+
+```go
+hooks := cliproxy.Hooks{
+  OnBeforeStart: func(cfg *config.Config) { log.Infof("starting on :%d", cfg.Port) },
+  OnAfterStart:  func(s *cliproxy.Service) { log.Info("ready") },
+}
+svc, _ := cliproxy.NewBuilder().WithConfig(cfg).WithConfigPath("config.yaml").WithHooks(hooks).Build()
+```
+
+## Shutdown
+
+`Run` defers `Shutdown`, so cancelling the parent context is enough. To stop manually:
+
+```go
+ctx, cancel := context.WithTimeout(context.Background(), 10*time.Second)
+defer cancel()
+_ = svc.Shutdown(ctx)
+```
+
+## Notes
+
+- Hot reload: changes to `config.yaml` and `auths/` are picked up automatically.
+- Request logging can be toggled at runtime via the Management API.
+- Gemini Web features (`gemini-web.*`) are honored in the embedded server.

+# CLI Proxy SDK 使用指南
+
+`sdk/cliproxy` 模块将代理能力以 Go 库的形式对外暴露，方便在其它服务中内嵌路由、鉴权、热更新与翻译层，而无需依赖可执行的 CLI 程序。
+
+## 安装与导入
+
+```bash
+go get github.com/router-for-me/CLIProxyAPI/v6/sdk/cliproxy
+```
+
+```go
+import (
+    "context"
+    "errors"
+    "time"
+
+    "github.com/router-for-me/CLIProxyAPI/v6/internal/config"
+    "github.com/router-for-me/CLIProxyAPI/v6/sdk/cliproxy"
+)
+```
+
+注意模块路径包含 `/v6`。
+
+## 最小可用示例
+
+```go
+cfg, err := config.LoadConfig("config.yaml")
+if err != nil { panic(err) }
+
+svc, err := cliproxy.NewBuilder().
+    WithConfig(cfg).
+    WithConfigPath("config.yaml"). // 绝对路径或工作目录相对路径
+    Build()
+if err != nil { panic(err) }
+
+ctx, cancel := context.WithCancel(context.Background())
+defer cancel()
+
+if err := svc.Run(ctx); err != nil && !errors.Is(err, context.Canceled) {
+    panic(err)
+}
+```
+
+服务内部会管理配置与认证文件的监听、后台令牌刷新与优雅关闭。取消上下文即可停止服务。
+
+## 服务器可选项（中间件、路由、日志）
+
+通过 `WithServerOptions` 自定义：
+
+```go
+svc, _ := cliproxy.NewBuilder().
+  WithConfig(cfg).
+  WithConfigPath("config.yaml").
+  WithServerOptions(
+    // 追加全局中间件
+    cliproxy.WithMiddleware(func(c *gin.Context) { c.Header("X-Embed", "1"); c.Next() }),
+    // 提前调整 gin 引擎（如 CORS、trusted proxies）
+    cliproxy.WithEngineConfigurator(func(e *gin.Engine) { e.ForwardedByClientIP = true }),
+    // 在默认路由之后追加自定义路由
+    cliproxy.WithRouterConfigurator(func(e *gin.Engine, _ *handlers.BaseAPIHandler, _ *config.Config) {
+      e.GET("/healthz", func(c *gin.Context) { c.String(200, "ok") })
+    }),
+    // 覆盖请求日志的创建（启用/目录）
+    cliproxy.WithRequestLoggerFactory(func(cfg *config.Config, cfgPath string) logging.RequestLogger {
+      return logging.NewFileRequestLogger(true, "logs", filepath.Dir(cfgPath))
+    }),
+  ).
+  Build()
+```
+
+这些选项与 CLI 服务器内部用法保持一致。
+
+## 管理 API（内嵌时）
+
+- 仅当 `config.yaml` 中设置了 `remote-management.secret-key` 时才会挂载管理端点。
+- 远程访问还需要 `remote-management.allow-remote: true`。
+- 具体端点见 MANAGEMENT_API_CN.md。内嵌服务器会在配置端口下暴露 `/v0/management`。
+
+## 使用核心鉴权管理器
+
+服务内部使用核心 `auth.Manager` 负责选择、执行、自动刷新。内嵌时可自定义其传输或钩子：
+
+```go
+core := coreauth.NewManager(coreauth.NewFileStore(cfg.AuthDir), nil, nil)
+core.SetRoundTripperProvider(myRTProvider) // 按账户返回 *http.Transport
+
+svc, _ := cliproxy.NewBuilder().
+    WithConfig(cfg).
+    WithConfigPath("config.yaml").
+    WithCoreAuthManager(core).
+    Build()
+```
+
+实现每个账户的自定义传输：
+
+```go
+type myRTProvider struct{}
+func (myRTProvider) RoundTripperFor(a *coreauth.Auth) http.RoundTripper {
+    if a == nil || a.ProxyURL == "" { return nil }
+    u, _ := url.Parse(a.ProxyURL)
+    return &http.Transport{ Proxy: http.ProxyURL(u) }
+}
+```
+
+管理器提供编程式执行接口：
+
+```go
+// 非流式
+resp, err := core.Execute(ctx, []string{"gemini"}, req, opts)
+
+// 流式
+chunks, err := core.ExecuteStream(ctx, []string{"gemini"}, req, opts)
+for ch := range chunks { /* ... */ }
+```
+
+说明：运行 `Service` 时会自动注册内置的提供商执行器；若仅单独使用 `Manager` 而不启动 HTTP 服务器，则需要自行实现并注册满足 `auth.ProviderExecutor` 的执行器。
+
+## 自定义凭据来源
+
+当凭据不在本地文件系统时，替换默认加载器：
+
+```go
+type memoryTokenProvider struct{}
+func (p *memoryTokenProvider) Load(ctx context.Context, cfg *config.Config) (*cliproxy.TokenClientResult, error) {
+    // 从内存/远端加载并返回数量统计
+    return &cliproxy.TokenClientResult{}, nil
+}
+
+svc, _ := cliproxy.NewBuilder().
+  WithConfig(cfg).
+  WithConfigPath("config.yaml").
+  WithTokenClientProvider(&memoryTokenProvider{}).
+  WithAPIKeyClientProvider(cliproxy.NewAPIKeyClientProvider()).
+  Build()
+```
+
+## 启动钩子
+
+无需修改内部代码即可观察生命周期：
+
+```go
+hooks := cliproxy.Hooks{
+  OnBeforeStart: func(cfg *config.Config) { log.Infof("starting on :%d", cfg.Port) },
+  OnAfterStart:  func(s *cliproxy.Service) { log.Info("ready") },
+}
+svc, _ := cliproxy.NewBuilder().WithConfig(cfg).WithConfigPath("config.yaml").WithHooks(hooks).Build()
+```
+
+## 关闭
+
+`Run` 内部会延迟调用 `Shutdown`，因此只需取消父上下文即可。若需手动停止：
+
+```go
+ctx, cancel := context.WithTimeout(context.Background(), 10*time.Second)
+defer cancel()

+# SDK Watcher Integration
+
+The SDK service exposes a watcher integration that surfaces granular auth updates without forcing a full reload. This document explains the queue contract, how the service consumes updates, and how high-frequency change bursts are handled.
+
+## Update Queue Contract
+
+- `watcher.AuthUpdate` represents a single credential change. `Action` may be `add`, `modify`, or `delete`, and `ID` carries the credential identifier. For `add`/`modify` the `Auth` payload contains a fully populated clone of the credential; `delete` may omit `Auth`.
+- `WatcherWrapper.SetAuthUpdateQueue(chan<- watcher.AuthUpdate)` wires the queue produced by the SDK service into the watcher. The queue must be created before the watcher starts.
+- The service builds the queue via `ensureAuthUpdateQueue`, using a buffered channel (`capacity=256`) and a dedicated consumer goroutine (`consumeAuthUpdates`). The consumer drains bursts by looping through the backlog before reacquiring the select loop.
+
+## Watcher Behaviour
+
+- `internal/watcher/watcher.go` keeps a shadow snapshot of auth state (`currentAuths`). Each filesystem or configuration event triggers a recomputation and a diff against the previous snapshot to produce minimal `AuthUpdate` entries that mirror adds, edits, and removals.
+- Updates are coalesced per credential identifier. If multiple changes occur before dispatch (e.g., write followed by delete), only the final action is sent downstream.
+- The watcher runs an internal dispatch loop that buffers pending updates in memory and forwards them asynchronously to the queue. Producers never block on channel capacity; they just enqueue into the in-memory buffer and signal the dispatcher. Dispatch cancellation happens when the watcher stops, guaranteeing goroutines exit cleanly.
+
+## High-Frequency Change Handling
+
+- The dispatch loop and service consumer run independently, preventing filesystem watchers from blocking even when many updates arrive at once.
+- Back-pressure is absorbed in two places:
+  - The dispatch buffer (map + order slice) coalesces repeated updates for the same credential until the consumer catches up.
+  - The service channel capacity (256) combined with the consumer drain loop ensures several bursts can be processed without oscillation.
+- If the queue is saturated for an extended period, updates continue to be merged, so the latest state is eventually applied without replaying redundant intermediate states.
+
+## Usage Checklist
+
+1. Instantiate the SDK service (builder or manual construction).
+2. Call `ensureAuthUpdateQueue` before starting the watcher to allocate the shared channel.
+3. When the `WatcherWrapper` is created, call `SetAuthUpdateQueue` with the service queue, then start the watcher.
+4. Provide a reload callback that handles configuration updates; auth deltas will arrive via the queue and are applied by the service automatically through `handleAuthUpdate`.
+
+Following this flow keeps auth changes responsive while avoiding full reloads for every edit.

+# SDK Watcher集成说明
+
+本文档介绍SDK服务与文件监控器之间的增量更新队列，包括接口契约、高频变更下的处理策略以及接入步骤。
+
+## 更新队列契约
+
+- `watcher.AuthUpdate`描述单条凭据变更，`Action`可能为`add`、`modify`或`delete`，`ID`是凭据标识。对于`add`/`modify`会携带完整的`Auth`克隆，`delete`可以省略`Auth`。
+- `WatcherWrapper.SetAuthUpdateQueue(chan<- watcher.AuthUpdate)`用于将服务侧创建的队列注入watcher，必须在watcher启动前完成。
+- 服务通过`ensureAuthUpdateQueue`创建容量为256的缓冲通道，并在`consumeAuthUpdates`中使用专职goroutine消费；消费侧会主动“抽干”积压事件，降低切换开销。
+
+## Watcher行为
+
+- `internal/watcher/watcher.go`维护`currentAuths`快照，文件或配置事件触发后会重建快照并与旧快照对比，生成最小化的`AuthUpdate`列表。
+- 以凭据ID为维度对更新进行合并，同一凭据在短时间内的多次变更只会保留最新状态（例如先写后删只会下发`delete`）。
+- watcher内部运行异步分发循环：生产者只向内存缓冲追加事件并唤醒分发协程，即使通道暂时写满也不会阻塞文件事件线程。watcher停止时会取消分发循环，确保协程正常退出。
+
+## 高频变更处理
+
+- 分发循环与服务消费协程相互独立，因此即便短时间内出现大量变更也不会阻塞watcher事件处理。
+- 背压通过两级缓冲吸收：
+  - 分发缓冲（map + 顺序切片）会合并同一凭据的重复事件，直到消费者完成处理。
+  - 服务端通道的256容量加上消费侧的“抽干”逻辑，可平稳处理多个突发批次。
+- 当通道长时间处于高压状态时，缓冲仍持续合并事件，从而在消费者恢复后一次性应用最新状态，避免重复处理无意义的中间状态。
+
+## 接入步骤
+
+1. 实例化SDK Service（构建器或手工创建）。
+2. 在启动watcher之前调用`ensureAuthUpdateQueue`创建共享通道。
+3. watcher通过工厂函数创建后立刻调用`SetAuthUpdateQueue`注入通道，然后再启动watcher。
+4. Reload回调专注于配置更新；认证增量会通过队列送达，并由`handleAuthUpdate`自动应用。
+
+遵循上述流程即可在避免全量重载的同时保持凭据变更的实时性。
