DraftCrew

High-performance Go framework for AI agent orchestration.

Inspired by CrewAI — built for Go. Agents, tasks, crews, and all 6 process types (sequential, hierarchical, consensual, reflective, flow, state machine) in a single binary with zero runtime dependencies.

Why DraftCrew?

Python-based agent frameworks (CrewAI, AutoGen, LangGraph) are powerful but hit walls in production: GIL contention, no native concurrency, heavy dependency trees, and complex deployment. DraftCrew brings agent orchestration to Go's world:

• Goroutines, not GIL — true parallel agent execution via Go's concurrency model
• Static typing — catch misconfigurations at compile time, not runtime
• Single binary — no Python runtime, no pip install, no virtualenvs
• Type-safe tools — GetOutput[T](result) via generics, zero reflection
• Production observability — built-in event bus, telemetry, OpenTelemetry bridging
• MCP-native — Model Context Protocol client for tool discovery (stdio + SSE)

Status: v0.2 — A2A Protocol

All core primitives + A2A (agent-to-agent) delegation with HTTP+WebSocket transport, circuit breaker, and agent discovery. 12 packages with ≥80% coverage, GODOC clean, race-detector clean.

What works today

Where we're heading

DraftCrew aims to match CrewAI's feature set and then surpass it in areas where Go excels. The roadmap:

Near-term (v0.3–v0.5)

• MCP Server — expose agents as MCP-compatible endpoints
• Sandboxed tool execution — WASM and Docker-backed tool isolation
• Knowledge ingestion — RAG with PDF/CSV/URL sources
• Browser automation — chromedp-based web interaction
• Guardrails — output validation with retry
• Training/HITL loop — feedback-loop agent improvement

Long-term vision

• Visual workflow builder — DAG-based crew designer
• gRPC mesh server — distributed agent orchestration across machines
• Cloud control plane — fleet management for production agent deployments
• Training/fine-tuning pipeline — feedback-loop agent improvement

Out of scope (for now)

DraftCrew will not become a vector database, a training framework, or a cloud platform. We build the orchestration layer — you bring the infrastructure.

Quick start

package main

import (
    "context"
    "fmt"

    "github.com/bzdvdn/draftcrew/src/pkg/agent"
    "github.com/bzdvdn/draftcrew/src/pkg/crew"
    "github.com/bzdvdn/draftcrew/src/pkg/llm"
    "github.com/bzdvdn/draftcrew/src/pkg/task"
)

func main() {
    llmClient := llm.NewOpenAI("sk-...", "gpt-4")

    a := agent.New(agent.Config{
        Role:    "Researcher",
        Goal:    "Research Go 1.22 features",
        LLM:     llmClient,
        MaxIter: 15,
    })

    t := task.New(task.Config{
        Description:    "Find key features",
        ExpectedOutput: "List of features",
        Agent:          a,
    })

    c := crew.New(crew.Config{
        Agents:  []*agent.Agent{a},
        Tasks:   []*task.Task{t},
        Process: crew.ProcessSequential,
    })

    result, err := c.Kickoff(context.Background())
    if err != nil {
        panic(err)
    }
    fmt.Printf("%+v\n", result)
}
