+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+MinEGO is a Go-based Minecraft protocol implementation that generates packet codecs and data components for Minecraft Java Edition protocol version 1.21.6 (protocol 771). The project uses code generation to create serialization/deserialization code for Minecraft network packets and item components.
+
+## Architecture
+
+The project follows a modular architecture centered around code generation:
+
+- **`codec/data/component/`** - Contains Go structs for all Minecraft item components (e.g., damage, enchantments, custom_name). Each component implements the `slot.Component` interface with Type() and ID() methods.
+- **`codec/data/packet/game/`** - Contains client and server packet definitions following the Minecraft protocol specification
+- **`codec/data/slot/`** - Core slot/item stack implementation and component registration system
+- **`net/`** - Network layer implementation (currently empty)
+- **Protocol Reference** - `codec/data/packet/protocol.wiki` contains the complete Minecraft protocol specification from wiki.vg
+
+## Code Generation System
+
+The project uses a custom code generator called `packetizer` that processes Go structs marked with `//codec:gen` comments. This generates the necessary ReadFrom/WriteTo methods for network serialization.
+
+Key patterns:
+- Structs marked with `//codec:gen` will have codecs auto-generated
+- Structs marked with `//codec:ignore` are excluded from generation
+- Components must implement `Type() slot.ComponentID` and `ID() string` methods
+- Components are registered in `codec/data/component/components.go` using `slot.RegisterComponent()`
+
+## Development Commands
+
+### Code Generation
+```bash
+# Generate packet codecs (run from project root)
+./gen-packet.sh
+# This runs: packetizer ./codec
+```
+
+### Standard Go Commands
+```bash
+# Build the project
+go build
+
+# Run tests (if any exist)
+go test ./...
+
+# Format code
+go fmt ./...
+
+# Get dependencies
+go mod tidy
+```
+
+## Dependencies
+
+- **github.com/Tnze/go-mc** - Core Minecraft protocol library (uses forked version)
+- **packetizer** - Custom code generation tool (available at /root/go/bin/packetizer)
+
+## Working with Components
+
+When adding new Minecraft item components:
+1. Create the struct in `codec/data/component/` following existing patterns
+2. Add `//codec:gen` comment above the struct
+3. Implement `Type()` and `ID()` methods with correct component ID and namespace
+4. Register the component in `components.go` init() function
+5. Run `./gen-packet.sh` to generate codecs
+
+## Working with Packets
+
+When adding new packet types:
+1. Define the packet struct in appropriate `client/` or `server/` directory
+2. Add `//codec:gen` comment for auto-generation
+3. Register the packet in the appropriate packets map
+4. Run `./gen-packet.sh` to generate codecs
+
+## Module Path
+
+The project uses `git.konjactw.dev/patyhank/minego` as its module path and includes a replace directive for the go-mc dependency pointing to a custom fork.
+
+## Code Generation Tasks
+
+- **Java to Go Packet Conversion**: 
+  * Task to implement Game State packets by converting Java code from `~/GoProjects/mc-network-source/network/protocol/game` to Go structs
+  * Focus on maintaining the same read/write logic during translation
+  * Ensure packet structures match the original Java implementation
+  * Use packetizer for automatic codec generation
+
+## Reference Notes
+
+- PacketID Reference:
+  * In `/root/go/pkg/mod/git.konjactw.dev/patyhank/go-mc@v1.20.3-0.20250618004758-a3d57fde34e8/data/packetid/packetid.go`, you can find all packet IDs (excluding handshake stage)
+
+## Packet Serialization Techniques
+
+- 對於Optional封包資料 簡易的格式可以使用pk.Option[XXX,*XXX] 的方法 比較複雜的需要自己實作一個ReadFrom&WriteTo 並且移除codec:gen的標記
+
+### Example
+
+```go
+// ExampleTypeFull full example for codec generator
+//
+//codec:gen
+type ExampleTypeFull struct {
+	PlayerID         int32 `mc:"VarInt"`
+	PlayerName       string
+	UUID             uuid.UUID      `mc:"UUID"`
