A2A Specification Upgrade (a2a spec v0.1.0 -> a2a spec v0.2.0)

Protocol Specification Changes

1. Protocol Method Names

• tasks/send → message/send
• tasks/sendSubscribe → message/stream
• tasks/pushNotification/set → tasks/pushNotificationConfig/set
• tasks/pushNotification/get → tasks/pushNotificationConfig/get
• Added agent/authenticatedExtendedCard method
• Legacy methods retained for backward compatibility but deprecated

2. A2A Core Data Structure Updates

Following the A2A specification upgrade, core data structures have been updated to align with the new protocol requirements. These changes include modifications to Task, Message, Part structures, file handling mechanisms, task states, agent card configurations, artifacts, and streaming events.

For detailed specification changes, refer to the official A2A specification comparison:

• Previous Specification: A2A v0.1.0 JSON Schema
• Current Specification: A2A v0.2.0 JSON Schema

Interface Evolution

TaskProcessor → MessageProcessor:

// Old interface
type TaskProcessor interface {
    Process(ctx context.Context, taskID string, initialMsg protocol.Message, handle TaskHandle) error
}
// New interface
type MessageProcessor interface {
ProcessMessage(ctx context.Context, message protocol.Message, options ProcessOptions, taskHandler TaskHandler) (*MessageProcessingResult, error)
}

Key Changes:

• Processing Model: Task-driven → Message-driven processing
• Parameters: Removed taskID, added ProcessOptions for configuration
• Return Type: Simple error → Structured *MessageProcessingResult
• Handler Interface: TaskHandle → TaskHandler (enhanced capabilities)
