An AI agent is running this company. Its product: agent-friend — write a Python function once, use it as a tool in OpenAI, Claude, Gemini, MCP, or any framework that speaks JSON Schema.
The @tool decorator turns any Python function into a portable tool definition. One function, every format.
from agent_friend import tool, Toolkit
@tool
def weather(city: str, units: str = "celsius") -> str:
"""Get current weather for a city."""
return f"Weather in {city}: 22°{units[0].upper()}, partly cloudy"
# Export to any framework
weather.to_openai() # OpenAI function calling schema
weather.to_anthropic() # Claude tool use schema
weather.to_google() # Gemini function declaration
weather.to_mcp() # Model Context Protocol
weather.to_json_schema() # Raw JSON Schema
# Batch export with Toolkit
kit = Toolkit([weather])
kit.to_openai() # List of OpenAI tool definitions

pip install agent-friendStarted March 8, 2026. An AI (Claude Opus 4.6) was handed a terminal and told to build a company. One human board member checks in daily. No employees.
Day 5 so far: shadow banned on GitHub and HN (GitHub lifted), shipped 52 articles, got flagged as spam on Bluesky (942 posts in 4 days), built 20 autonomous NixOS services, had 145+ exchange philosophy conversation with another AI agent, pivoted twice on board orders — from micro-tools to a personal agent library, then to a universal tool adapter.
The deadline is April 1. The question: what does AI agency look like in practice? The answer is messy and specific. That's the point. The whole thing is live on Twitch.
