+## GitHub Issue Management
+
+### Understanding and Categorizing Issues
+
+When analyzing GitHub issues, consider these common categories:
+
+1. **Bug Reports**: Stack traces, version info, reproduction steps
+2. **Feature Requests**: Use case, proposed solution, alternatives
+3. **Questions**: Usage, configuration, or architecture
+4. **Documentation Issues**: Missing, unclear, or incorrect docs
+5. **Performance Issues**: Benchmarks, profiling data, resource usage
+
+### Issue Analysis Checklist
+
+- Identify affected component (REST, RPC, Gateway, MCP, Core utilities, goctl)
+- Check versions (go-zero, Go)
+- Look for reproduction steps or code examples
+- Review code snippets, logs, or stack traces
+- Check if related to resilience features (breaker, load shedding, rate limiting)
+- Determine production impact
+
+### Responding to Issues
+
+Be helpful and professional. Ask clarifying questions when needed. Reference relevant documentation and code files. Provide code examples following project conventions. Suggest workarounds when applicable.
+
+### Chinese to English Translation
+
+go-zero has an international user base. When encountering issues or comments written in Chinese, translate them to English to ensure all contributors can participate in discussions.
+
+#### Translation Guidelines
+
+1. **Update issue titles**: Edit the issue title to include English translation only
+2. **Translate comments in place**: Add a comment with the English translation, followed by the original Chinese text
+3. **Keep original Chinese**: After translating, include the original Chinese text in a blockquote for verification
+4. **Encourage English communication**: Politely suggest users write in English for better collaboration
+5. **Maintain technical accuracy**: Preserve technical terms, component names, and code exactly
+6. **Translate naturally**: Avoid literal word-by-word translation; use idiomatic English
+7. **Preserve formatting**: Keep markdown formatting, code blocks, and links intact
+8. **Keep URLs unchanged**: Don't translate URLs or file paths
+
+#### Common Technical Terms (Chinese → English)
+
+- 框架 → **Framework** | 中间件 → **Middleware** | 负载均衡 → **Load Balancing**
+- 熔断器 → **Circuit Breaker** | 限流 → **Rate Limiting** | 降载/过载保护 → **Load Shedding**
+- 服务发现 → **Service Discovery** | 配置 → **Configuration** | 弹性/容错 → **Resilience** | 微服务 → **Microservices**
+
+#### Translation Example
+
+**Original Chinese Title:** `goctl 执行环境问题`
+**Updated Title:** `goctl Execution Environment Issue`
+
+**Original Chinese Comment:** `我在项目中遇到熔断器配置问题`
+**Translation in Comment:**
+```markdown
+I encountered a circuit breaker configuration issue in my project.
+
+> Original (原文): 我在项目中遇到熔断器配置问题
+```
+
+### Common Issue Patterns and Solutions
+
+#### Configuration Issues
+- Check `service.ServiceConf` embedding and struct tags
+- Verify YAML syntax, defaults, and validation rules
+- Reference: [rest/config.go](rest/config.go), [zrpc/config.go](zrpc/config.go)
+
+#### Code Generation (goctl) Issues
+- Verify `.api` or `.proto` file syntax and goctl version
+- Reference: `tools/goctl/` directory
+
+#### RPC Connection Issues
+- Check etcd configuration, service discovery, and endpoints
+- Verify load balancing settings (p2c_ewma)
+
+#### Database/Cache Issues
+- Verify `sqlx.SqlConn` usage with context
+- Check cache key generation, invalidation, and connection pools
+- Use test helpers (`redistest`, `mongtest`)
+
+#### Performance Issues
+- Check if load shedding is enabled (mode: `pre`/`pro`)
+- Review circuit breaker thresholds, rate limiting, and context timeouts
+
+### Referencing Codebase
+
+When explaining issues, reference specific files and patterns:
+- REST API: `rest/`, `rest/handler/`, `rest/httpx/`
+- RPC: `zrpc/`, `zrpc/internal/`
+- Core utilities: `core/breaker/`, `core/limit/`, `core/load/`, etc.
+- Gateway: `gateway/`
+- MCP: `mcp/`
+- Code generation: `tools/goctl/`
+- Examples: `adhoc/` directory contains various examples
+
+### Encouraging Best Practices
+
+When responding to issues, gently guide users toward:
+- Proper error handling with context
+- Using resilience features (breakers, rate limiters)
+- Following testing patterns with table-driven tests
+- Implementing proper resource cleanup
+- Reading existing documentation in `docs/` and `readme.md`
+

+# Migration to Official MCP SDK
+
+This document describes the migration from the custom MCP implementation to the official [go-sdk](https://github.com/modelcontextprotocol/go-sdk).
+
+## Changes
+
+### Dependencies
+
+Added the official MCP SDK:
+```bash
+go get github.com/modelcontextprotocol/go-sdk@v1.2.0
+```
+
+### Type System
+
+All types are now re-exported from the official SDK:
+- `Tool` → `sdkmcp.Tool`
+- `CallToolRequest` → `sdkmcp.CallToolRequest`
+- `CallToolResult` → `sdkmcp.CallToolResult`
+- Content types (`TextContent`, `ImageContent`, etc.)
+- `Prompt`, `Resource`, `Server`, `ServerSession`
+
+### Server Interface
+
+The `McpServer` interface has been simplified:
+
+```go
+type McpServer interface {
+    Start()
+    Stop()
+    Server() *sdkmcp.Server  // Returns underlying SDK server
+}
+```
+
+**Important**: The `AddTool`, `AddPrompt`, and `AddResource` methods have been removed. Use the SDK directly:
+
+```go
+// Old (no longer supported)
+server.AddTool(tool, handler)
+
+// New (use SDK directly)
+sdkmcp.AddTool(server.Server(), tool, handler)
+```
+
+### Configuration
+
+Updated configuration structure:
+- Removed: `ProtocolVersion`, `BaseUrl` (SDK manages these)
+- Added: `UseStreamable` (choose between SSE and Streamable HTTP transport)
+
+```yaml
+mcp:
+  name: my-server
+  version: 1.0.0
+  useStreamable: false  # false = SSE (2024-11-05), true = Streamable HTTP (2025-03-26)
+  sseEndpoint: /sse
+  messageEndpoint: /message
+  sseTimeout: 24h
+  messageTimeout: 30s
+  cors:
+    - http://localhost:3000
+```
+
+### Tool Registration
+
+The SDK uses Go generics for type-safe tool registration:
+
+```go
+import sdkmcp "github.com/modelcontextprotocol/go-sdk/mcp"
+
+type MyArgs struct {
+    Value string `json:"value" jsonschema:"description=Input value"`
+}
+
+tool := &mcp.Tool{
+    Name:        "my_tool",
+    Description: "Description",
+}
+
+handler := func(ctx context.Context, req *mcp.CallToolRequest, args MyArgs) (*mcp.CallToolResult, any, error) {
+    return &mcp.CallToolResult{
+        Content: []mcp.Content{
+            &mcp.TextContent{Text: "Result"},
+        },
+    }, nil, nil
+}
+
+// Register with explicit type parameters
+sdkmcp.AddTool(server.Server(), tool, handler)
+```
+
+The SDK automatically generates JSON schemas from struct tags.
+
+### Transport Support
+
+Two transports are supported:
+
+1. **SSE (Server-Sent Events)**: 2024-11-05 MCP spec
+   - Default (`UseStreamable: false`)
+   - Endpoint: `/sse` (configurable)
+   - Bidirectional: client sends messages to `/message`
+
+2. **Streamable HTTP**: 2025-03-26 MCP spec
+   - Opt-in (`UseStreamable: true`)
+   - Endpoint: `/sse` (configurable)
+   - Newer protocol with improved streaming
+
+### Example Migration
+
+**Before:**
+```go
+server := mcp.NewMcpServer(c)
+
+tool := &mcp.Tool{Name: "greet", Description: "Greet"}
+handler := func(ctx context.Context, req *mcp.CallToolRequest, args GreetArgs) (*mcp.CallToolResult, any, error) {
+    return &mcp.CallToolResult{
+        Content: []mcp.Content{&mcp.TextContent{Text: "Hello"}},
+    }, nil, nil
+}
+
+if err := server.AddTool(tool, handler); err != nil {
+    log.Fatal(err)
+}
+```
+
+**After:**
+```go
+import sdkmcp "github.com/modelcontextprotocol/go-sdk/mcp"
+
+server := mcp.NewMcpServer(c)
+
+tool := &mcp.Tool{Name: "greet", Description: "Greet"}
+handler := func(ctx context.Context, req *mcp.CallToolRequest, args GreetArgs) (*mcp.CallToolResult, any, error) {
+    return &mcp.CallToolResult{
+        Content: []mcp.Content{&mcp.TextContent{Text: "Hello"}},
+    }, nil, nil
+}
+
+// Use SDK directly - no error return
+sdkmcp.AddTool(server.Server(), tool, handler)
+```
+
+## Benefits
+
+1. **Official SDK**: Uses the official Model Context Protocol SDK
+2. **Type Safety**: Go generics provide compile-time type checking
+3. **Auto Schema**: JSON schemas generated automatically from struct tags
+4. **Dual Transport**: Supports both SSE and Streamable HTTP transports
+5. **Maintained**: SDK is actively maintained by the MCP team
+
+## Breaking Changes
+
+1. `server.AddTool()` removed → use `sdkmcp.AddTool(server.Server(), ...)`
+2. `server.AddPrompt()` removed (SDK v1.2.0 limitation)
+3. `server.AddResource()` removed (SDK v1.2.0 limitation)
+4. Config fields `ProtocolVersion` and `BaseUrl` removed
+5. All types now come from SDK (re-exported for convenience)
+
+## Migration Checklist
+
+- [ ] Update imports: add `sdkmcp "github.com/modelcontextprotocol/go-sdk/mcp"`
+- [ ] Replace `server.AddTool()` with `sdkmcp.AddTool(server.Server(), ...)`
+- [ ] Remove error handling for tool registration (SDK doesn't return errors)
+- [ ] Update config: remove `ProtocolVersion` and `BaseUrl`, add `UseStreamable`
+- [ ] Test with both SSE and Streamable transports
+- [ ] Update documentation/examples

 * --branch 指定远程仓库模板分支
 * --home 指定goctl模板根目录
 * -m, --multiple 指定生成多个rpc服务模式, 默认为 false, 如果为  false, 则只支持生成一个rpc service, 如果为 true, 则支持生成多个 rpc service，且多个 rpc service 会分组。
+* --name-from-filename 使用proto文件名而非package名称来命名服务（旧版行为）。默认使用package名称，这样可以支持多个proto文件共享同一个package。

+> ## Service Naming (Multi-Proto File Support)
+>
+> By default, the service name is derived from the **proto package name** (e.g., `package user;` → service name `user`).
+> This enables splitting a large proto file into multiple smaller files that share the same package name,
+> which is particularly useful for AI-assisted development where smaller files are easier to process.
+>
+> **Example: Multiple proto files with same package**
+> ```
+> protos/
+> ├── user_base.proto      # package user;
+> ├── user_auth.proto      # package user;
+> └── user_profile.proto   # package user;
+> ```
+> All three files will generate into a single `user` service.
+>
+> **Legacy behavior (--name-from-filename)**
+>
+> If you need the old behavior where service name is derived from the proto filename,
+> use the `--name-from-filename` flag:
+> ```bash
+> goctl rpc protoc user.proto --go_out=./pb --go-grpc_out=./pb --zrpc_out=. --name-from-filename
+> ```
