Personal Simple Generic Agents

FivcPlayground

An intelligent agent ecosystem built on Strands for autonomous tool generation, task assessment, and dynamic agent orchestration.

🔄 Dual Backend Support: FivcPlayground supports both Strands (default) and LangChain backends. See Backend Selection Guide for details on switching backends.

🎯 Overview

FivcPlayground provides a flexible multi-agent system that can:

• Assess tasks intelligently to determine the best approach
• Retrieve and use tools dynamically based on task requirements
• Plan and execute complex workflows with specialized agents
• Generate and optimize tools autonomously
• Chat and assist users through an interactive web interface

🚀 Quickstart

Prerequisites

• Python 3.10 or higher
• API keys for LLM providers (OpenAI, Ollama, etc.)

Installation

# Install with uv (recommended)
make install        # runtime + dev dependencies

# Or minimal installation
make install-min    # runtime only

# Or with pip
pip install -e .

Configuration

1. Copy the example environment file:

cp .env.example .env

2. Configure your LLM provider settings in .env:

# OpenAI
OPENAI_API_KEY=your_key_here
OPENAI_BASE_URL=https://api.openai.com/v1

# Or Ollama
OLLAMA_BASE_URL=http://localhost:11434

Quick Start

# Launch the web interface
make serve

# Or run an agent from CLI
uv run fivcplayground run Generic --query "What is machine learning?"

# Show available commands
uv run fivcplayground --help

Available Agents

• Generic - Standard agent for general task execution
• Companion - Friendly chat agent for conversations
• Consultant - Assesses tasks and recommends approaches
• Planner - Creates execution plans and teams
• Researcher - Analyzes patterns and workflows
• Engineer - Develops and optimizes tools
• Evaluator - Assesses performance and quality

Web Interface

FivcPlayground includes a modern web interface built with Streamlit:

# Launch web interface (default: localhost:8501)
fivcplayground web

# Or using Make
make serve

# Development mode with auto-reload
make serve-dev

# Custom port and host
fivcplayground web --port 8080 --host 0.0.0.0

Features:

• 💬 Interactive chat interface - Natural conversation with agents
• 🔄 Async execution - Non-blocking, responsive interface
• 🛠️ Tool integration - Automatic tool selection and execution
• 📝 Conversation history - Full session management
• 🎨 Modern UI - Clean, intuitive Streamlit interface

See Web Interface Documentation for detailed usage instructions.

🧰 Available Tools

FivcPlayground includes built-in tools and supports MCP (Model Context Protocol) tools:

Built-in Tools:

• calculator - Mathematical calculations
• current_time - Current date and time
• python_repl - Python code execution

MCP Tools: Configure MCP servers in configs/mcp.yaml to add additional tools dynamically.
