Pygent 0.3
Pygent is a PyTorch-like framework for composing LLM agents with no hidden per-call state from reusable Module graphs. Version 0.3 provides a single Execution owner for direct and managed calls, an asyncio Runtime, observable model/tool events, OpenAI-compatible adapters, portable tools and MCP adapters, ReAct, SQLite recovery, and HTTP/SSE workers.
First principles
Pygent 0.3 第一原则 is the repository's highest authority. Module-specific first principles, SDK contracts, tests, examples, and code derive from it.
Quickstart
from pygent import AIMessage, Context, RecurrentModule, UserMessage
class Echo(RecurrentModule):
async def forward(self, message, context):
output = AIMessage(content=message.content.upper())
return output, context + message + output
message, context = await Echo().invoke(UserMessage(content="hello"), Context())
Direct invoke(), stream(), and start() need no Runtime. Bind a Module to LocalRuntime when its call contract is supported and the application needs bounded concurrency, cancellation, deadlines, remote placement, durable history, or advanced Execution control. This standard recurrent example returns (message, context); ordinary Module inputs and results are user-defined. See the Execution contract.
