moss-autogen

MOSS signing integration for AutoGen. Unsigned output is broken output.

Installation

pip install moss-autogen

Quick Start: Explicit Signing (Recommended)

Sign messages, function results, and conversations:

from autogen import AssistantAgent
from moss_autogen import sign_message, sign_function_result, sign_conversation

# Create your agent
agent = AssistantAgent(name="analyst", llm_config={"model": "gpt-4"})

# Get a reply and sign it
reply = agent.generate_reply(messages=[{"content": "Analyze this"}])
result = sign_message(reply, agent_id="analyst")
print(f"Signed: {result.signature[:20]}...")

# Sign function/tool results
func_result = execute_tool(args)
result = sign_function_result(func_result, agent_id="analyst", function="execute_tool")

# Sign entire conversation
result = sign_conversation(chat_history, agent_id="chat-session")

Enterprise Mode

Set MOSS_API_KEY for automatic policy evaluation:

import os
os.environ["MOSS_API_KEY"] = "your-api-key"

from moss_autogen import sign_message, enterprise_enabled

print(f"Enterprise: {enterprise_enabled()}")  # True

result = sign_message(
    {"role": "assistant", "content": "Transfer approved"},
    agent_id="finance-agent",
    context={"user_id": "u123", "action": "transfer"}
)

if result.blocked:
    print(f"Blocked by policy: {result.policy.reason}")

Verification

from moss_autogen import verify_envelope

verify_result = verify_envelope(result.envelope)
if verify_result.valid:
    print(f"Signed by: {verify_result.subject}")

All Functions

Legacy API

The old wrapper API is still available:

from moss_autogen import signed_agent

agent = signed_agent(
    AssistantAgent(name="analyst", ...),
    "moss:lab:analyst"
)
# agent.moss_envelope available after each reply
