+# GitHub Copilot Instructions for go-zero
+
+This document provides guidelines for GitHub Copilot when assisting with development in the go-zero project.
+
+## Project Overview
+
+go-zero is a web and RPC framework with lots of built-in engineering practices designed to ensure the stability of busy services with resilience design. It has been serving sites with tens of millions of users for years.
+
+### Key Architecture Components
+
+- **REST API framework** (`rest/`) - HTTP service framework with middleware chain support
+- **RPC framework** (`zrpc/`) - gRPC-based RPC framework with etcd service discovery and p2c_ewma load balancing
+- **Gateway** (`gateway/`) - API gateway supporting both HTTP and gRPC upstreams with proto-based routing
+- **MCP Server** (`mcp/`) - Model Context Protocol server for AI agent integration via SSE
+- **Core utilities** (`core/`) - Production-grade components:
+  - Resilience: circuit breakers (`breaker/`), rate limiters (`limit/`), adaptive load shedding (`load/`)
+  - Storage: SQL with cache (`stores/sqlc/`), Redis (`stores/redis/`), MongoDB (`stores/mongo/`)
+  - Concurrency: MapReduce (`mr/`), worker pools (`executors/`), sync primitives (`syncx/`)
+  - Observability: metrics (`metric/`), tracing (`trace/`), structured logging (`logx/`)
+- **Code generation tool** (`tools/goctl/`) - CLI tool for generating Go code from `.api` and `.proto` files
+
+## Coding Standards and Conventions
+
+### Code Style
+
+1. **Follow Go conventions**: Use `gofmt` for formatting, follow effective Go practices
+2. **Package naming**: Use lowercase, single-word package names when possible
+3. **Error handling**: Always handle errors explicitly, use `errorx.BatchError` for multiple errors
+4. **Context propagation**: Always pass `context.Context` as the first parameter for functions that may block
+5. **Configuration structures**: Use struct tags with JSON annotations, defaults, and validation
+
+**Pattern**: All service configs embed `service.ServiceConf` for common fields (Name, Log, Mode, Telemetry)
+```go
+type Config struct {
+    service.ServiceConf              // Always embed for services
+    Host     string `json:",default=0.0.0.0"`
+    Port     int    // Required field (no default)
+    Timeout  int64  `json:",default=3000"`  // Timeouts in milliseconds
+    Optional string `json:",optional"`      // Optional field
+    Mode     string `json:",default=pro,options=dev|test|rt|pre|pro"`  // Validated options
+}
+```
+
+**Service modes**: `dev`/`test`/`rt` disable load shedding and stats; `pre`/`pro` enable all resilience features
+
+### Interface Design
+
+1. **Small interfaces**: Follow Go's preference for small, focused interfaces
+2. **Context methods**: Provide both context and non-context versions of methods
+3. **Options pattern**: Use functional options for complex configuration
+
+Example:
+```go
+func (c *Client) Get(key string, val any) error {
+    return c.GetCtx(context.Background(), key, val)
+}
+
+func (c *Client) GetCtx(ctx context.Context, key string, val any) error {
+    // implementation
+}
+```
+
+### Testing Patterns
+
+1. **Test file naming**: Use `*_test.go` suffix
+2. **Test function naming**: Use `TestFunctionName` pattern
+3. **Use testify/assert**: Prefer `assert` package for assertions
+4. **Table-driven tests**: Use table-driven tests for multiple scenarios
+5. **Mock interfaces**: Use `go.uber.org/mock` for mocking
+6. **Test helpers**: Use `redistest`, `mongtest` helpers for database testing
+
+Example test pattern:
+```go
+func TestSomething(t *testing.T) {
+    tests := []struct {
+        name     string
+        input    string
+        expected string
+        wantErr  bool
+    }{
+        {"valid case", "input", "output", false},
+        {"error case", "bad", "", true},
+    }
+
+    for _, tt := range tests {
+        t.Run(tt.name, func(t *testing.T) {
+            result, err := SomeFunction(tt.input)
+            if tt.wantErr {
+                assert.Error(t, err)
+                return
+            }
+            assert.NoError(t, err)
+            assert.Equal(t, tt.expected, result)
+        })
+    }
+}
+```
+
+## Framework-Specific Guidelines
+
+### REST API Development
+
+1. **API Definition**: Use `.api` files to define REST APIs with goctl codegen
+2. **Handler pattern**: Separate business logic into logic packages (handlers call logic layer)
+3. **Middleware chain**: Middlewares wrap via `chain.Chain` interface - use `Append()` or `Prepend()` to control order
+   - Built-in middlewares (all in `rest/handler/`): tracing, logging, metrics, recovery, breaker, shedding, timeout, maxconns, maxbytes, gunzip
+   - Custom middleware: `func(http.Handler) http.Handler` - call `next.ServeHTTP(w, r)` to continue chain
+4. **Response handling**: Use `httpx.WriteJson(w, code, v)` for JSON responses
+5. **Error handling**: Use `httpx.Error(w, err)` or `httpx.ErrorCtx(ctx, w, err)` for HTTP error responses
+6. **Route registration**: Routes defined with `Method`, `Path`, and `Handler` - wildcards use `:param` syntax
+
+### RPC Development
+
+1. **Protocol Buffers**: Use protobuf for service definitions, generate code with goctl
+2. **Service discovery**: Use etcd for dynamic service registration/discovery, or direct endpoints for static routing
+3. **Load balancing**: Default is `p2c_ewma` (power of 2 choices with EWMA), configurable via `BalancerName`
+4. **Client configuration**: Support `Etcd`, `Endpoints`, or `Target` - use `BuildTarget()` to construct connection string
+5. **Interceptors**: Implement gRPC interceptors for cross-cutting concerns (auth, logging, metrics)
+6. **Health checks**: gRPC health checks enabled by default (`Health: true`)
+
+### Database Operations
+
+1. **SQL operations**: Use `sqlx.SqlConn` interface - methods always end with `Ctx` for context support
+2. **Caching pattern**: `stores/sqlc` provides `CachedConn` for automatic cache-aside pattern
+   - `QueryRowCtx`: Query with cache key, auto-populate on cache miss
+   - `ExecCtx`: Execute and delete cache keys
+3. **Transactions**: Use `sqlx.SqlConn.TransactCtx()` to get transaction session
+4. **Connection pooling**: Managed automatically (64 max idle/open, 1min lifetime)
+5. **Test helpers**: Use `redistest.CreateRedis(t)` for Redis, SQL mocks for DB testing
+
+Example cache pattern:
+```go
+err := c.QueryRowCtx(ctx, &dest, key, func(ctx context.Context, conn sqlx.SqlConn) error {
+    return conn.QueryRowCtx(ctx, &dest, query, args...)
+})
+```
+
+### Configuration Management
+
+1. **YAML configuration**: Use YAML for configuration files
+2. **Environment variables**: Support environment variable overrides
+3. **Validation**: Include proper validation for configuration parameters
+4. **Sensible defaults**: Provide reasonable default values
+
+## Error Handling Best Practices
+
+1. **Wrap errors**: Use `fmt.Errorf` with `%w` verb to wrap errors
+2. **Custom errors**: Define custom error types when needed
+3. **Error logging**: Log errors appropriately with context
+4. **Graceful degradation**: Implement fallback mechanisms
+
+## Performance Considerations
+
+1. **Resource pools**: Use connection pools and worker pools
+2. **Circuit breakers**: Implement circuit breaker patterns for external calls
+3. **Rate limiting**: Apply rate limiting to protect services
+4. **Load shedding**: Implement adaptive load shedding
+5. **Metrics**: Add appropriate metrics and monitoring
+
+## Security Guidelines
+
+1. **Input validation**: Validate all input parameters
+2. **SQL injection prevention**: Use parameterized queries
+3. **Authentication**: Implement proper JWT token handling
+4. **HTTPS**: Support TLS/HTTPS configurations
+5. **CORS**: Configure CORS appropriately for web APIs
+
+## Documentation Standards
+
+1. **Package documentation**: Include package-level documentation
+2. **Function documentation**: Document exported functions with examples
+3. **API documentation**: Maintain API documentation in sync
+4. **README updates**: Update README for significant changes
+
+## Common Patterns to Follow
+
+### Service Configuration
+```go
+type ServiceConf struct {
+    Name string
+    Log  logx.LogConf
+    Mode string `json:",default=pro,options=[dev,test,pre,pro]"`
+    // ... other common fields
+}
+```
+
+### Middleware Implementation
+```go
+func SomeMiddleware() rest.Middleware {
+    return func(next http.HandlerFunc) http.HandlerFunc {
+        return func(w http.ResponseWriter, r *http.Request) {
+            // Pre-processing
+            next.ServeHTTP(w, r)
+            // Post-processing
+        }
+    }
+}
+```
+
+### Resource Management
+Always implement proper resource cleanup using defer and context cancellation.
+
+## Build and Test Commands
+
+- Build: `go build ./...`
+- Test: `go test ./...`  
+- Test with race detection: `go test -race ./...`
+- Format: `gofmt -w .`
+- Code generation:
+  - REST API: `goctl api go -api *.api -dir .`
+  - RPC: `goctl rpc protoc *.proto --go_out=. --go-grpc_out=. --zrpc_out=.`
+  - Model from SQL: `goctl model mysql datasource -url="user:pass@tcp(host:port)/db" -table="*" -dir="./model"`
+
+## Critical Architecture Patterns
+
+### Resilience Design Philosophy
+go-zero implements defense-in-depth with multiple protection layers:
+1. **Circuit Breaker** (`core/breaker`): Google SRE breaker - tracks success/failure, opens on error threshold
+2. **Adaptive Load Shedding** (`core/load`): CPU-based auto-rejection when system overloaded (disabled in dev/test/rt modes)
+3. **Rate Limiting** (`core/limit`): Token bucket (Redis-based) and period limiters
+4. **Timeout Control**: Cascading timeouts via context - set at multiple levels (client, server, handler)
+
+### Middleware Chain Architecture
+`rest/chain` provides middleware composition:
+```go
+// Middleware signature
+type Middleware func(http.Handler) http.Handler
+
+// Chain operations
+chain := chain.New(m1, m2)
+chain.Append(m3)    // Adds to end: m1 -> m2 -> m3
+chain.Prepend(m0)   // Adds to start: m0 -> m1 -> m2 -> m3
+handler := chain.Then(finalHandler)
+```
+
+### Concurrency Patterns
+- **MapReduce** (`core/mr`): Parallel processing with worker pools - use for batch operations
+- **Executors** (`core/executors`): Bulk/period executors for batching operations
+- **SingleFlight** (`core/syncx`): Deduplicates concurrent identical requests
+
+Remember to run tests and ensure all checks pass before submitting changes. The project emphasizes high quality, performance, and reliability, so these should be primary considerations in all development work.

+# Migrating from 1.x to 2.0
+
+To upgrade imports of the Go Driver from v1 to v2, we recommend using [marwan-at-work/mod
+](https://github.com/marwan-at-work/mod):
+
+```
+mod upgrade --mod-name=go.mongodb.org/mongo-driver
+```
+
+# Notice
+After completing the mod upgrade, code changes are typically unnecessary in the vast majority of cases. However, if your project references packages including but not limited to those listed below, you'll need to manually replace them, as these libraries are no longer present in the v2 version.
+```go
+go.mongodb.org/mongo-driver/bson/bsonrw    => go.mongodb.org/mongo-driver/v2/bson
+go.mongodb.org/mongo-driver/bson/bsoncodec => go.mongodb.org/mongo-driver/v2/bson
+go.mongodb.org/mongo-driver/bson/primitive => go.mongodb.org/mongo-driver/v2/bson
+```
+
+See the following resources to learn more about upgrading from version 1.x to 2.0.:

+# Migrating from 1.x to 2.0
+
+To upgrade imports of the Go Driver from v1 to v2, we recommend using [marwan-at-work/mod
+](https://github.com/marwan-at-work/mod):
+
+```
+mod upgrade --mod-name=go.mongodb.org/mongo-driver
+```
+
+# Notice
+After completing the mod upgrade, code changes are typically unnecessary in the vast majority of cases. However, if your project references packages including but not limited to those listed below, you'll need to manually replace them, as these libraries are no longer present in the v2 version.
+```go
+go.mongodb.org/mongo-driver/bson/bsonrw    => go.mongodb.org/mongo-driver/v2/bson
+go.mongodb.org/mongo-driver/bson/bsoncodec => go.mongodb.org/mongo-driver/v2/bson
+go.mongodb.org/mongo-driver/bson/primitive => go.mongodb.org/mongo-driver/v2/bson
+```

+See the following resources to learn more about upgrading from version 1.x to 2.0.:
