# Autonomous Multi-Agent Swarm with Anthropic Claude Engine
from lixvn import SwarmRuntime, Tool, Agent
from anthropic import Anthropic

# 1. Initialize Claude 3.5 Sonnet core engine
client = Anthropic(api_key="your-claude-api-key")
runtime = SwarmRuntime(model="claude-3-5-sonnet-latest", engine=client)

# 2. Define self-healing tool interfaces
@runtime.tool
def execute_sql_query(query: str) -> dict:
    """Executes verified read queries against primary data warehouse"""
    return runtime.db.safe_execute(query)

# 3. Spawn autonomous researcher & auditor agents
planner = Agent(name="Lead Architect", role="Context breakdown & planning")
auditor = Agent(name="Security Auditor", role="SQL injection check & schema safety")

result = runtime.dispatch(
    goal="Analyze customer churn pattern and report anomalies",
    agents=[planner, auditor]
)
print(f"[STATUS 200] Run Completed. Tokens: {result.total_tokens}")
✨ Optimized for Claude for Startups

Powered by Anthropic's State-of-the-Art Reasoning

Lixvn leverages Claude 3.5 Sonnet's 200K token window, deep reasoning traces, and industry-leading tool-use benchmark performance to eliminate hallucinated tool calls and infinite loop traps.

  • ✓ Claude Code Native: CLI tool integrations with full terminal protocol compatibility.
  • ✓ Structured JSON Outputs: Deterministic JSON schema validation for autonomous function dispatch.
  • ✓ High Throughput: Batch streaming inference support for low-latency production workloads.
