Highlights

File Checkpointing (Issue #32)

Track file changes during sessions and rewind to any checkpoint:

client := claudecode.NewClient(claudecode.WithFileCheckpointing())
// ... capture UUID from UserMessage
err := client.RewindFiles(ctx, messageUUID)

In-Process SDK MCP Server (Issue #7)

Define custom tools that run in-process (Go equivalent of Python's @tool decorator):

addTool := claudecode.NewTool("add", "Add two numbers", schema, handler)
calculator := claudecode.CreateSDKMcpServer("calc", "1.0.0", addTool)
client := claudecode.NewClient(claudecode.WithSdkMcpServer("calc", calculator))

SDK Release Notes

This release achieves 100% Python SDK feature parity with Go-native patterns.
