AgentKit

A Go library for building AI agent applications. Provides server factories, LLM abstractions, workflow orchestration, and multi-runtime deployment support.

Features

• Server Factories - A2A and HTTP servers in 5 lines (saves ~475 lines per project)
• Multi-Provider LLM - Gemini, Claude, OpenAI, xAI, Ollama via OmniLLM
• Workflow Orchestration - Type-safe graph-based execution with Eino
• Multi-Runtime Deployment - Kubernetes (Helm) or AWS AgentCore
• VaultGuard Integration - Security-gated credential access

Quick Example

package main

import (
    "context"

    "github.com/plexusone/agentkit/a2a"
    "github.com/plexusone/agentkit/agent"
    "github.com/plexusone/agentkit/config"
    "github.com/plexusone/agentkit/httpserver"
)

func main() {
    ctx := context.Background()
    cfg := config.LoadConfig()

    // Create agent
    ba, _ := agent.NewBaseAgent(cfg, "research-agent", 30)
    researchAgent := NewResearchAgent(ba, cfg)

    // HTTP server - 5 lines
    httpServer, _ := httpserver.NewBuilder("research-agent", 8001).
        WithHandlerFunc("/research", researchAgent.HandleResearch).
        Build()

    // A2A server - 5 lines
    a2aServer, _ := a2a.NewServer(a2a.Config{
        Agent:       researchAgent.ADKAgent(),
        Port:        "9001",
        Description: "Research agent for web search",
    })

    // Start servers
    a2aServer.StartAsync(ctx)
    httpServer.Start()
}

Benefits

AgentKit eliminates ~1,500 lines of boilerplate per project:

Component	Lines Saved
A2A server factory	~350 lines
HTTP server factory	~125 lines
Shared pkg/ code	~930 lines
