Fast Agent

This project is an autonomous agent workflow engine and multi-agent orchestration framework. It provides a runtime for managing agent lifecycles and a provider-agnostic abstraction layer for interacting with multiple large language model backends through standardized requests and structured outputs.

The framework features a reliability layer for output verification, utilizing sampling-based majority voting and generator-evaluator feedback loops to refine model responses. It supports complex coordination patterns including sequential chaining, parallel execution with fan-in aggregation, and recursive agent nesting where child agents are registered as tools for parent agents.

The system covers a broad capability surface including task decomposition through capability-based routing and stateful conversation inheritance. It integrates with the Model Context Protocol for standardized data exchange and allows for the registration of Python functions as tools. Additional functionality includes human-in-the-loop intervention, multimodal resource support, and a command line interface for interactive agent communication and filesystem code patching.

  • Agent Command Line Interfaces - Provides a terminal interface for executing agent tasks and managing communication sessions.
  • Response Reliability Voting - Implements sampling-based majority voting to verify and improve the reliability of agent outputs.
  • AI and Agents - Tool for building and evaluating AI agents.
