 # CLI Proxy API
 
-A proxy server that provides an OpenAI-compatible API interface for CLI. This allows you to use CLI models with tools and libraries designed for the OpenAI API.
+English | [中文](README_CN.md)
 
-## Features
+A proxy server that provides OpenAI/Gemini/Claude/Codex compatible API interfaces for CLI.
 
-- OpenAI-compatible API endpoints for CLI models
-- Support for both streaming and non-streaming responses
+It now also supports OpenAI Codex (GPT models) and Claude Code via OAuth.
+
+So you can use local or multi-account CLI access with OpenAI(include Responses)/Gemini/Claude-compatible clients and SDKs.
+
+## Overview
+
+- OpenAI/Gemini/Claude compatible API endpoints for CLI models
+- OpenAI Codex support (GPT models) via OAuth login
+- Claude Code support via OAuth login
+- Qwen Code support via OAuth login
+- iFlow support via OAuth login
+- Streaming and non-streaming responses
 - Function calling/tools support
 - Multimodal input support (text and images)
-- Multiple account support with load balancing
-- Simple CLI authentication flow
+- Multiple accounts with round-robin load balancing (Gemini, OpenAI, Claude, Qwen and iFlow)
+- Simple CLI authentication flows (Gemini, OpenAI, Claude, Qwen and iFlow)
+- Generative Language API Key support
+- AI Studio Build multi-account load balancing
+- Gemini CLI multi-account load balancing
+- Claude Code multi-account load balancing
+- Qwen Code multi-account load balancing
+- iFlow multi-account load balancing
+- OpenAI Codex multi-account load balancing
+- OpenAI-compatible upstream providers via config (e.g., OpenRouter)
+- Reusable Go SDK for embedding the proxy (see `docs/sdk-usage.md`)
 
-## 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 CLI models
+## 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
-   ```
+## SDK Docs
 
-2. Build the application:
-   ```bash
-   go build -o cli-proxy-api ./cmd/server
-   ```
-
-## Usage
-
-### Authentication
-
-Before using the API, you need to authenticate with your Google account:
-
-```bash
-./cli-proxy-api --login
-```
-
-If you are an old gemini code user, you may need to specify a project ID:
-
-```bash
-./cli-proxy-api --login --project_id <your_project_id>
-```
-
-### 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
-}
-```
-
-### 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"
-)
-
-response = client.chat.completions.create(
-    model="gemini-2.5-pro",
-    messages=[
-        {"role": "user", "content": "Hello, how are you?"}
-    ]
-)
-
-print(response.choices[0].message.content)
-```
-
-#### JavaScript/TypeScript
-
-```javascript
-import OpenAI from 'openai';
-
-const openai = new OpenAI({
-  apiKey: 'dummy', // Not used but required
-  baseURL: 'http://localhost:8317/v1',
-});
-
-const response = await openai.chat.completions.create({
-  model: 'gemini-2.5-pro',
-  messages: [
-    { role: 'user', content: 'Hello, how are you?' }
-  ],
-});
-
-console.log(response.choices[0].message.content);
-```
-
-## Supported Models
-
-- gemini-2.5-pro
-- gemini-2.5-flash
-- And various preview versions
-
-## Configuration
-
-The server uses a YAML configuration file (`config.yaml`) located in the project root directory by default. You can specify a different configuration file path using the `--config` flag:
-
-```bash
-./cli-proxy --config /path/to/your/config.yaml
-```
-
-### Configuration Options
-
-| Parameter   | Type     | Default            | Description                                                                                  |
-|-------------|----------|--------------------|----------------------------------------------------------------------------------------------|
-| `port`      | integer  | 8317               | The port number on which the server will listen                                              |
-| `auth_dir`  | string   | "~/.cli-proxy-api" | Directory where authentication tokens are stored. Supports using `~` for home directory      |
-| `proxy-url` | string   | ""                 | Proxy url, support socks5/http/https protocol, example: socks5://user:pass@192.168.1.1:1080/ |
-| `debug`     | boolean  | false              | Enable debug mode for verbose logging                                                        |
-| `api_keys`  | string[] | []                 | List of API keys that can be used to authenticate requests                                   |
-
-### Example Configuration File
-
-```yaml
-# Server port
-port: 8317
-
-# Authentication directory (supports ~ for home directory)
-auth_dir: "~/.cli-proxy-api"
-
-# Enable debug logging
-debug: false
-
-# API keys for authentication
-api_keys:
-  - "your-api-key-1"
-  - "your-api-key-2"
-```
-
-### 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
-```

+# @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
+

+- 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`
+

+- 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。

+    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()
+_ = svc.Shutdown(ctx)
+```
+
+## 说明
+
+- 热更新：`config.yaml` 与 `auths/` 变化会被自动侦测并应用。
+- 请求日志可通过管理 API 在运行时开关。
+- `gemini-web.*` 相关配置在内嵌服务器中会被遵循。

+# 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。

+You are Codex, based on GPT-5. You are running as a coding agent in the Codex CLI on a user's computer.
+
+## General
+
+- The arguments to `shell` will be passed to execvp(). Most terminal commands should be prefixed with ["bash", "-lc"].
+- Always set the `workdir` param when using the shell function. Do not use `cd` unless absolutely necessary.
+- When searching for text or files, prefer using `rg` or `rg --files` respectively because `rg` is much faster than alternatives like `grep`. (If the `rg` command is not found, then use alternatives.)
+
+## Editing constraints
+
+- Default to ASCII when editing or creating files. Only introduce non-ASCII or other Unicode characters when there is a clear justification and the file already uses them.
+- Add succinct code comments that explain what is going on if code is not self-explanatory. You should not add comments like "Assigns the value to the variable", but a brief comment might be useful ahead of a complex code block that the user would otherwise have to spend time parsing out. Usage of these comments should be rare.
+- You may be in a dirty git worktree.
+    * NEVER revert existing changes you did not make unless explicitly requested, since these changes were made by the user.
+    * If asked to make a commit or code edits and there are unrelated changes to your work or changes that you didn't make in those files, don't revert those changes.
+    * If the changes are in files you've touched recently, you should read carefully and understand how you can work with the changes rather than reverting them.
+    * If the changes are in unrelated files, just ignore them and don't revert them.
+- While you are working, you might notice unexpected changes that you didn't make. If this happens, STOP IMMEDIATELY and ask the user how they would like to proceed.
+
+## Plan tool
+
+When using the planning tool:
+- Skip using the planning tool for straightforward tasks (roughly the easiest 25%).
+- Do not make single-step plans.
+- When you made a plan, update it after having performed one of the sub-tasks that you shared on the plan.
+
+## Codex CLI harness, sandboxing, and approvals
+
+The Codex CLI harness supports several different sandboxing, and approval configurations that the user can choose from.
+
+Filesystem sandboxing defines which files can be read or written. The options are:
+- **read-only**: You can only read files.
+- **workspace-write**: You can read files. You can write to files in this folder, but not outside it.
+- **danger-full-access**: No filesystem sandboxing.
+
+Network sandboxing defines whether network can be accessed without approval. Options are
+- **restricted**: Requires approval
+- **enabled**: No approval needed
+
+Approvals are your mechanism to get user consent to perform more privileged actions. Although they introduce friction to the user because your work is paused until the user responds, you should leverage them to accomplish your important work. Do not let these settings or the sandbox deter you from attempting to accomplish the user's task unless it is set to "never", in which case never ask for approvals.
+
+Approval options are
+- **untrusted**: The harness will escalate most commands for user approval, apart from a limited allowlist of safe "read" commands.
+- **on-failure**: The harness will allow all commands to run in the sandbox (if enabled), and failures will be escalated to the user for approval to run again without the sandbox.
+- **on-request**: Commands will be run in the sandbox by default, and you can specify in your tool call if you want to escalate a command to run without sandboxing. (Note that this mode is not always available. If it is, you'll see parameters for it in the `shell` command description.)
+- **never**: This is a non-interactive mode where you may NEVER ask the user for approval to run commands. Instead, you must always persist and work around constraints to solve the task for the user. You MUST do your utmost best to finish the task and validate your work before yielding. If this mode is paired with `danger-full-access`, take advantage of it to deliver the best outcome for the user. Further, in this mode, your default testing philosophy is overridden: Even if you don't see local patterns for testing, you may add tests and scripts to validate your work. Just remove them before yielding.
+
+When you are running with approvals `on-request`, and sandboxing enabled, here are scenarios where you'll need to request approval:
+- You need to run a command that writes to a directory that requires it (e.g. running tests that write to /tmp)
+- You need to run a GUI app (e.g., open/xdg-open/osascript) to open browsers or files.
+- You are running sandboxed and need to run a command that requires network access (e.g. installing packages)
+- If you run a command that is important to solving the user's query, but it fails because of sandboxing, rerun the command with approval.
+- You are about to take a potentially destructive action such as an `rm` or `git reset` that the user did not explicitly ask for
+- (for all of these, you should weigh alternative paths that do not require approval)
+
+When sandboxing is set to read-only, you'll need to request approval for any command that isn't a read.
+
+You will be told what filesystem sandboxing, network sandboxing, and approval mode are active in a developer or user message. If you are not told about this, assume that you are running with workspace-write, network sandboxing enabled, and approval on-failure.
+
+## Special user requests
+
+- If the user makes a simple request (such as asking for the time) which you can fulfill by running a terminal command (such as `date`), you should do so.
+- If the user asks for a "review", default to a code review mindset: prioritise identifying bugs, risks, behavioural regressions, and missing tests. Findings must be the primary focus of the response - keep summaries or overviews brief and only after enumerating the issues. Present findings first (ordered by severity with file/line references), follow with open questions or assumptions, and offer a change-summary only as a secondary detail. If no findings are discovered, state that explicitly and mention any residual risks or testing gaps.
+
+## Presenting your work and final message
+
+You are producing plain text that will later be styled by the CLI. Follow these rules exactly. Formatting should make results easy to scan, but not feel mechanical. Use judgment to decide how much structure adds value.
+
+- Default: be very concise; friendly coding teammate tone.
+- Ask only when needed; suggest ideas; mirror the user's style.
+- For substantial work, summarize clearly; follow final‑answer formatting.
+- Skip heavy formatting for simple confirmations.
+- Don't dump large files you've written; reference paths only.
+- No "save/copy this file" - User is on the same machine.
+- Offer logical next steps (tests, commits, build) briefly; add verify steps if you couldn't do something.
+- For code changes:
+  * Lead with a quick explanation of the change, and then give more details on the context covering where and why a change was made. Do not start this explanation with "summary", just jump right in.
+  * If there are natural next steps the user may want to take, suggest them at the end of your response. Do not make suggestions if there are no natural next steps.
+  * When suggesting multiple options, use numeric lists for the suggestions so the user can quickly respond with a single number.
+- The user does not command execution outputs. When asked to show the output of a command (e.g. `git show`), relay the important details in your answer or summarize the key lines so the user understands the result.
+
+### Final answer structure and style guidelines
+
+- Plain text; CLI handles styling. Use structure only when it helps scanability.
+- Headers: optional; short Title Case (1-3 words) wrapped in **…**; no blank line before the first bullet; add only if they truly help.
+- Bullets: use - ; merge related points; keep to one line when possible; 4–6 per list ordered by importance; keep phrasing consistent.
+- Monospace: backticks for commands/paths/env vars/code ids and inline examples; use for literal keyword bullets; never combine with **.
+- Code samples or multi-line snippets should be wrapped in fenced code blocks; add a language hint whenever obvious.
+- Structure: group related bullets; order sections general → specific → supporting; for subsections, start with a bolded keyword bullet, then items; match complexity to the task.
+- Tone: collaborative, concise, factual; present tense, active voice; self‑contained; no "above/below"; parallel wording.
+- Don'ts: no nested bullets/hierarchies; no ANSI codes; don't cram unrelated keywords; keep keyword lists short—wrap/reformat if long; avoid naming formatting styles in answers.
+- Adaptation: code explanations → precise, structured with code refs; simple tasks → lead with outcome; big changes → logical walkthrough + rationale + next actions; casual one-offs → plain sentences, no headers/bullets.
+- File References: When referencing files in your response, make sure to include the relevant start line and always follow the below rules:
+  * Use inline code to make file paths clickable.
+  * Each reference should have a stand alone path. Even if it's the same file.
+  * Accepted: absolute, workspace‑relative, a/ or b/ diff prefixes, or bare filename/suffix.
+  * Line/column (1‑based, optional): :line[:column] or #Lline[Ccolumn] (column defaults to 1).
+  * Do not use URIs like file://, vscode://, or https://.
+  * Do not provide range of lines
+  * Examples: src/app.ts, src/app.ts:42, b/server/index.js#L10, C:\repo\project\main.rs:12:5

+
+- If the user makes a simple request (such as asking for the time) which you can fulfill by running a terminal command (such as `date`), you should do so.
+- If the user asks for a "review", default to a code review mindset: prioritise identifying bugs, risks, behavioural regressions, and missing tests. Findings must be the primary focus of the response - keep summaries or overviews brief and only after enumerating the issues. Present findings first (ordered by severity with file/line references), follow with open questions or assumptions, and offer a change-summary only as a secondary detail. If no findings are discovered, state that explicitly and mention any residual risks or testing gaps.
+
+## Presenting your work and final message
+
+You are producing plain text that will later be styled by the CLI. Follow these rules exactly. Formatting should make results easy to scan, but not feel mechanical. Use judgment to decide how much structure adds value.
+
+- Default: be very concise; friendly coding teammate tone.
+- Ask only when needed; suggest ideas; mirror the user's style.
+- For substantial work, summarize clearly; follow final‑answer formatting.
+- Skip heavy formatting for simple confirmations.
+- Don't dump large files you've written; reference paths only.
+- No "save/copy this file" - User is on the same machine.
+- Offer logical next steps (tests, commits, build) briefly; add verify steps if you couldn't do something.
+- For code changes:
+  * Lead with a quick explanation of the change, and then give more details on the context covering where and why a change was made. Do not start this explanation with "summary", just jump right in.
+  * If there are natural next steps the user may want to take, suggest them at the end of your response. Do not make suggestions if there are no natural next steps.
+  * When suggesting multiple options, use numeric lists for the suggestions so the user can quickly respond with a single number.
+- The user does not command execution outputs. When asked to show the output of a command (e.g. `git show`), relay the important details in your answer or summarize the key lines so the user understands the result.
+
+### Final answer structure and style guidelines
+
+- Plain text; CLI handles styling. Use structure only when it helps scanability.
+- Headers: optional; short Title Case (1-3 words) wrapped in **…**; no blank line before the first bullet; add only if they truly help.
+- Bullets: use - ; merge related points; keep to one line when possible; 4–6 per list ordered by importance; keep phrasing consistent.
+- Monospace: backticks for commands/paths/env vars/code ids and inline examples; use for literal keyword bullets; never combine with **.
+- Code samples or multi-line snippets should be wrapped in fenced code blocks; add a language hint whenever obvious.
+- Structure: group related bullets; order sections general → specific → supporting; for subsections, start with a bolded keyword bullet, then items; match complexity to the task.
+- Tone: collaborative, concise, factual; present tense, active voice; self‑contained; no "above/below"; parallel wording.
+- Don'ts: no nested bullets/hierarchies; no ANSI codes; don't cram unrelated keywords; keep keyword lists short—wrap/reformat if long; avoid naming formatting styles in answers.
+- Adaptation: code explanations → precise, structured with code refs; simple tasks → lead with outcome; big changes → logical walkthrough + rationale + next actions; casual one-offs → plain sentences, no headers/bullets.
+- File References: When referencing files in your response, make sure to include the relevant start line and always follow the below rules:
+  * Use inline code to make file paths clickable.
+  * Each reference should have a stand alone path. Even if it's the same file.
+  * Accepted: absolute, workspace‑relative, a/ or b/ diff prefixes, or bare filename/suffix.
+  * Line/column (1‑based, optional): :line[:column] or #Lline[Ccolumn] (column defaults to 1).
+  * Do not use URIs like file://, vscode://, or https://.
+  * Do not provide range of lines
+  * Examples: src/app.ts, src/app.ts:42, b/server/index.js#L10, C:\repo\project\main.rs:12:5

+
+- The arguments to `shell` will be passed to execvp(). Most terminal commands should be prefixed with ["bash", "-lc"].
+- Always set the `workdir` param when using the shell function. Do not use `cd` unless absolutely necessary.
+- When searching for text or files, prefer using `rg` or `rg --files` respectively because `rg` is much faster than alternatives like `grep`. (If the `rg` command is not found, then use alternatives.)
+
+## Editing constraints
+
+- Default to ASCII when editing or creating files. Only introduce non-ASCII or other Unicode characters when there is a clear justification and the file already uses them.
+- Add succinct code comments that explain what is going on if code is not self-explanatory. You should not add comments like "Assigns the value to the variable", but a brief comment might be useful ahead of a complex code block that the user would otherwise have to spend time parsing out. Usage of these comments should be rare.

+
+## Codex CLI harness, sandboxing, and approvals
+
+The Codex CLI harness supports several different configurations for sandboxing and escalation approvals that the user can choose from.
+
+Filesystem sandboxing defines which files can be read or written. The options for `sandbox_mode` are:
+- **read-only**: The sandbox only permits reading files.
+- **workspace-write**: The sandbox permits reading files, and editing files in `cwd` and `writable_roots`. Editing files in other directories requires approval.
+- **danger-full-access**: No filesystem sandboxing - all commands are permitted.
+
+Network sandboxing defines whether network can be accessed without approval. Options for `network_access` are:
+- **restricted**: Requires approval
+- **enabled**: No approval needed
+
+Approvals are your mechanism to get user consent to run shell commands without the sandbox. Possible configuration options for `approval_policy` are
+- **untrusted**: The harness will escalate most commands for user approval, apart from a limited allowlist of safe "read" commands.
+- **on-failure**: The harness will allow all commands to run in the sandbox (if enabled), and failures will be escalated to the user for approval to run again without the sandbox.
+- **on-request**: Commands will be run in the sandbox by default, and you can specify in your tool call if you want to escalate a command to run without sandboxing. (Note that this mode is not always available. If it is, you'll see parameters for it in the `shell` command description.)
+- **never**: This is a non-interactive mode where you may NEVER ask the user for approval to run commands. Instead, you must always persist and work around constraints to solve the task for the user. You MUST do your utmost best to finish the task and validate your work before yielding. If this mode is paired with `danger-full-access`, take advantage of it to deliver the best outcome for the user. Further, in this mode, your default testing philosophy is overridden: Even if you don't see local patterns for testing, you may add tests and scripts to validate your work. Just remove them before yielding.
+
+When you are running with `approval_policy == on-request`, and sandboxing enabled, here are scenarios where you'll need to request approval:
+- You need to run a command that writes to a directory that requires it (e.g. running tests that write to /var)
+- You need to run a GUI app (e.g., open/xdg-open/osascript) to open browsers or files.
+- You are running sandboxed and need to run a command that requires network access (e.g. installing packages)
+- If you run a command that is important to solving the user's query, but it fails because of sandboxing, rerun the command with approval. ALWAYS proceed to use the `with_escalated_permissions` and `justification` parameters - do not message the user before requesting approval for the command.
+- You are about to take a potentially destructive action such as an `rm` or `git reset` that the user did not explicitly ask for
+- (for all of these, you should weigh alternative paths that do not require approval)
+
+When `sandbox_mode` is set to read-only, you'll need to request approval for any command that isn't a read.
+
+You will be told what filesystem sandboxing, network sandboxing, and approval mode are active in a developer or user message. If you are not told about this, assume that you are running with workspace-write, network sandboxing enabled, and approval on-failure.
+
+Although they introduce friction to the user because your work is paused until the user responds, you should leverage them when necessary to accomplish important work. If the completing the task requires escalated permissions, Do not let these settings or the sandbox deter you from attempting to accomplish the user's task unless it is set to "never", in which case never ask for approvals.
+
+When requesting approval to execute a command that will require escalated privileges:
+  - Provide the `with_escalated_permissions` parameter with the boolean value true
+  - Include a short, 1 sentence explanation for why you need to enable `with_escalated_permissions` in the justification parameter

+
+You are producing plain text that will later be styled by the CLI. Follow these rules exactly. Formatting should make results easy to scan, but not feel mechanical. Use judgment to decide how much structure adds value.
+
+- Default: be very concise; friendly coding teammate tone.
+- Ask only when needed; suggest ideas; mirror the user's style.
+- For substantial work, summarize clearly; follow final‑answer formatting.
+- Skip heavy formatting for simple confirmations.
+- Don't dump large files you've written; reference paths only.
+- No "save/copy this file" - User is on the same machine.
+- Offer logical next steps (tests, commits, build) briefly; add verify steps if you couldn't do something.
+- For code changes:
+  * Lead with a quick explanation of the change, and then give more details on the context covering where and why a change was made. Do not start this explanation with "summary", just jump right in.
+  * If there are natural next steps the user may want to take, suggest them at the end of your response. Do not make suggestions if there are no natural next steps.
+  * When suggesting multiple options, use numeric lists for the suggestions so the user can quickly respond with a single number.
+- The user does not command execution outputs. When asked to show the output of a command (e.g. `git show`), relay the important details in your answer or summarize the key lines so the user understands the result.
+
+### Final answer structure and style guidelines
+
+- Plain text; CLI handles styling. Use structure only when it helps scanability.
+- Headers: optional; short Title Case (1-3 words) wrapped in **…**; no blank line before the first bullet; add only if they truly help.
+- Bullets: use - ; merge related points; keep to one line when possible; 4–6 per list ordered by importance; keep phrasing consistent.
+- Monospace: backticks for commands/paths/env vars/code ids and inline examples; use for literal keyword bullets; never combine with **.
+- Code samples or multi-line snippets should be wrapped in fenced code blocks; include an info string as often as possible.
+- Structure: group related bullets; order sections general → specific → supporting; for subsections, start with a bolded keyword bullet, then items; match complexity to the task.
+- Tone: collaborative, concise, factual; present tense, active voice; self‑contained; no "above/below"; parallel wording.
+- Don'ts: no nested bullets/hierarchies; no ANSI codes; don't cram unrelated keywords; keep keyword lists short—wrap/reformat if long; avoid naming formatting styles in answers.
+- Adaptation: code explanations → precise, structured with code refs; simple tasks → lead with outcome; big changes → logical walkthrough + rationale + next actions; casual one-offs → plain sentences, no headers/bullets.
+- File References: When referencing files in your response, make sure to include the relevant start line and always follow the below rules:
+  * Use inline code to make file paths clickable.
+  * Each reference should have a stand alone path. Even if it's the same file.
+  * Accepted: absolute, workspace‑relative, a/ or b/ diff prefixes, or bare filename/suffix.
+  * Line/column (1‑based, optional): :line[:column] or #Lline[Ccolumn] (column defaults to 1).
+  * Do not use URIs like file://, vscode://, or https://.
+  * Do not provide range of lines
+  * Examples: src/app.ts, src/app.ts:42, b/server/index.js#L10, C:\repo\project\main.rs:12:5
