serialization

# Serialization Skill Expert skill for binary and text serialization formats, schema design, and performance optimization. ## Capabilities - **Protocol Buffers**: Generate Protocol Buffer schemas and code for multiple languages - **FlatBuffers**: Design FlatBuffers schemas for zero-copy deserialization - **MessagePack/CBOR**: Implement MessagePack and CBOR binary encoding - **Performance Analysis**: Analyze and compare serialization performance - **Format Comparison**: Compare serialization formats for specific use cases - **Deserialization Debugging**: Debug deserialization issues and version mismatches - **Payload Optimization**: Optimize payload sizes and encoding efficiency - **Schema Evolution**: Handle backward/forward compatible schema changes ## Tools and Dependencies - `protoc` - Protocol Buffer compiler - `flatc` - FlatBuffers compiler - `msgpack-tools` - MessagePack utilities - `cbor-tools` - CBOR utilities - `capnp` - Cap'n Proto compiler - `avro-tools` - Apache Avro utilities ## Target Processes - binary-protocol-parser.js - custom-protocol-design.js - message-framing.js - websocket-server.js ## Usage Examples ### Protocol Buffers Schema ```protobuf syntax = "proto3"; package network; message Packet { uint32 sequence = 1; bytes payload = 2; int64 timestamp = 3; map<string, string> headers = 4; } ``` ### FlatBuffers Schema ```fbs namespace Network; table Packet { sequence: uint32; payload: [ubyte]; timestamp: int64; headers: [KeyValue]; } table KeyValue { key: string; value: string; } root_type Packet; ``` ### Code Generation ```bash protoc --python_out=. --go_out=. packet.proto flatc --python --go packet.fbs ``` ### Performance Benchmarking ```bash hyperfine 'protoc-bench encode message.proto' 'msgpack-bench encode message.json' ``` ## Quality Gates - Schema validation passes - Backward compatibility verified - Performance benchmarks met - Cross-language interoperability tested - Payload size within requirements
