coreouto
A minimal, extensible agent library for Python.
Built on five philosophies: minimalism, extensibility, explicitness, fragmentation, conciseness.
The whole library reduces to one idea: an agent is called with a message, runs an internal loop, and returns its response when the model produces a response with text content and no tool calls — that response's text becomes the final answer. Unrecoverable provider terminations (token cap, refusal, content filter, server-side failure) also end the loop. Everything else — providers, tools, presets, hooks, multi-agent — is an opt-in extension.
import os
import coreouto as co
from coreouto.providers.openai import OpenAIProvider
@co.register_tool("search")
def search(query: str) -> str:
"""Search the web for `query`."""
return f"<results for {query}>"
co.register_provider("minimax", OpenAIProvider(
api_key=os.environ["MINIMAX_API_KEY"],
base_url="https://api.minimax.io/v1",
))
preset = co.register_agent_preset(
"researcher", model="MiniMax-M3", provider="minimax",
system_prompt="You are a research assistant.",
tools=["search"],
)
response = co.Agent(preset.to_config()).call_sync("Find me recent news about fusion energy.")
print(response.content)
