AgentSDK

A Python SDK for building multi-agent systems with Bedrock-backed LLMs, ReAct tool-use, and parallel sub-agent orchestration.

Install

pip install agentsdk

Quickstart

from agentsdk import (
  BedrockClient, SessionManager, ToolRegistry, Agent,
  OrchestratorAgent, load_sub_agents_from_dir,
  FileSystemTool, ShellTool, WebFetchTool,
)

bedrock = BedrockClient(model_id="openai.gpt-oss-120b-1:0", region_name="us-west-2")
sessions = SessionManager()
registry = ToolRegistry()
registry.register(FileSystemTool(root="."))
registry.register(ShellTool(root="."))
registry.register(WebFetchTool())

def on_thought(agent, kind, text):
    print(f"[{agent}][{kind}] {text[:160]}")

default = Agent(
  name="default", bedrock=bedrock, registry=registry,
  sessions=sessions, system_prompt="You are a helpful coding assistant.",
  on_thought=on_thought,
)
subs = load_sub_agents_from_dir(".agents", base_agent=default)

orch = OrchestratorAgent(
  planner=default, sub_agents=subs, sessions=sessions,
)

print(orch.run(session_id="sess1", query="Audit repo for secrets and summarize."))

CLI

agentsdk run --agents-dir .agents --show-thoughts --query "Your task"
