Setup

1. Install Dependencies

# Create and activate virtual environment (recommended)
python3 -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

# Install required packages
pip install -r requirements.txt

# Install Hecate for terminal tools
git clone git@github.com:NousResearch/hecate.git
cd hecate
pip install -e .
cd ..

2. Configure Environment Variables

# Copy the example environment file
cp .env.example .env

# Edit .env and add your API keys
nano .env  # or use your preferred editor

Required API Keys:

• ANTHROPIC_API_KEY - Main agent model (get at: https://console.anthropic.com/)
• FIRECRAWL_API_KEY - Web tools (get at: https://firecrawl.dev/)
• NOUS_API_KEY - Vision & reasoning tools (get at: https://inference-api.nousresearch.com/)
• MORPH_API_KEY - Terminal tools (get at: https://morph.so/)
• FAL_KEY - Image generation (get at: https://fal.ai/)
• OPENAI_API_KEY - Optional, for some Hecate features

See .env.example for all available configuration options including debug settings and terminal tool configuration.

Toolsets System

The agent uses a toolsets system for organizing and managing tools. All tools must be part of a toolset to be accessible - individual tool selection is not supported. This ensures consistent and logical grouping of capabilities.

Key Concepts

• Toolsets: Logical groups of tools for specific use cases (e.g., "research", "development", "debugging")
• Composition: Toolsets can include other toolsets for powerful combinations
• Custom Toolsets: Create your own toolsets at runtime or by editing toolsets.py
• Toolset-Only Access: Tools are only accessible through toolsets, not individually

Available Toolsets

See toolsets.py for the complete list of predefined toolsets including:

• Basic toolsets (web, terminal, vision, creative, reasoning)
• Composite toolsets (research, development, analysis, etc.)
• Scenario-specific toolsets (debugging, documentation, API testing, etc.)
• Special toolsets (safe mode without terminal, minimal, offline)

Using Toolsets

# Use a predefined toolset
python run_agent.py --enabled_toolsets=research --query "Find latest AI papers"

# Combine multiple toolsets
python run_agent.py --enabled_toolsets=web,vision --query "Analyze this website"

# Enable all toolsets explicitly (same as omitting the flag)
python run_agent.py --enabled_toolsets=all --query "Do web research and run commands if helpful"

# Safe mode (no terminal access)
python run_agent.py --enabled_toolsets=safe --query "Help without running commands"

# List all available toolsets and tools
python run_agent.py --list_tools

For detailed documentation on toolsets, see TOOLSETS_README.md.

Basic Usage

Default (all tools enabled)

python run_agent.py \
  --query "search up the latest docs on jit in python 3.13 and write me basic example that's not in their docs. profile its perf" \
  --max_turns 20 \
  --model claude-sonnet-4-20250514 \
  --base_url https://api.anthropic.com/v1/ \
  --api_key $ANTHROPIC_API_KEY

With specific toolset

python run_agent.py \
  --query "Debug this Python error" \
  --enabled_toolsets=debugging \
  --model claude-sonnet-4-20250514 \
  --api_key $ANTHROPIC_API_KEY

Python API

from run_agent import AIAgent

# Use a specific toolset
agent = AIAgent(
    model="claude-opus-4-20250514",
    enabled_toolsets=["research"]
)
response = agent.chat("Find information about quantum computing")

# Create custom toolset at runtime
from toolsets import create_custom_toolset

create_custom_toolset(
    name="my_tools",
    description="My custom toolkit",
    tools=["web_search"],
    includes=["terminal", "vision"]
)

agent = AIAgent(enabled_toolsets=["my_tools"])

Batch Processing

Process multiple prompts from a dataset in parallel with automatic checkpointing and statistics tracking:

# Basic batch processing
python batch_runner.py \
  --dataset_file=prompts.jsonl \
  --batch_size=20 \
  --run_name=my_run

# With specific distribution
python batch_runner.py \
  --dataset_file=prompts.jsonl \
  --batch_size=20 \
  --run_name=image_run \
  --distribution=image_gen \
  --num_workers=4

Key Features:

• Parallel processing with configurable workers
• Toolset distributions for varied data generation
• Automatic checkpointing and resume capability
• Combined output in data/<run_name>/trajectories.jsonl
• Tool usage statistics and success rates

Quick Start: See QUICKSTART_BATCH.md for a 5-minute getting started guide.
Full Documentation: See BATCH_PROCESSING.md for comprehensive documentation.
