Implementation Guide

Setting Up Agent Swarm

from openai import OpenAI

# API call pattern from Moonshot docs (OpenAI-compatible endpoint)
client = OpenAI(
    base_url="https://api.moonshot.ai/v1",
    api_key="YOUR_MOONSHOT_API_KEY"
)

response = client.chat.completions.create(
    model="kimi-k2.5",
    messages=[
        {"role": "system", "content": "You are Kimi."},
        {"role": "user", "content": "Plan and execute this complex multi-step task."}
    ],
    tools=[
        # add tool definitions here
    ]
)

Tool Integration

Kimi K2.5 Agent Swarm supports diverse tool ecosystems:

available_tools = {

# Example: Dynamic reallocation
if task_complexity == "high":
    swarm.reallocate(
        from_pool="documentation",
        to_pool="coding",
        count=5
    )

Best Practices

Designing Effective Swarms

  1. Clear Role Definition: Each agent should have specific responsibilities
  2. Appropriate Granularity: Balance between too many/few agents
  3. Communication Protocols: Establish clear message formats
  4. Error Handling: Plan for agent failure scenarios
  5. Resource Monitoring: Track computational costs
