version.go

Overview

This file defines the current version constant of the ADK Go module. It provides a single exported string constant Version representing the semantic version of the ADK Go library. This version identifier is primarily used for tagging requests made to large language models (LLMs), enabling tracking and compatibility checks in distributed or version-dependent workflows.

Code Elements

Constant: Version

const Version string = "0.1.0"

• Type: string

• Value: "0.1.0" (Semantic version string)

• Purpose: Exposes the current version of the ADK Go module.

• Usage: This constant is used to tag or annotate LLM requests or other communications where knowing the client or SDK version is necessary. This helps in debugging, telemetry, backward compatibility, and conditional logic based on versioning.

Example Usage:

import "path/to/version"

func sendRequest() {
    // Include version tag in request metadata
    metadata := map[string]string{
        "clientVersion": version.Version,
    }
    // Use metadata in LLM request context
}

Implementation Details

• The version is a constant string literal, indicating that it is immutable at runtime.

• It follows semantic versioning, which can be extended or updated as new releases occur.

• No additional logic or dynamic version resolution is implemented in this file.

• The simplicity of this file ensures minimal dependencies and straightforward integration into other modules.

Interaction with Other System Components

• The Version constant is primarily consumed by components responsible for LLM request generation and telemetry.

• It is used in tagging LLM requests as described in LLM Integration and Agents, helping identify which version of the ADK Go client is making the request.

• The version information can also be used by logging and telemetry modules, such as those described in Telemetry and Observability, to correlate events with client versions.

• When combined with session or workflow management modules (Session Management, Agent Workflow Management), version tags help maintain compatibility and traceability across agent executions.
