Hermes Agent

An AI agent with advanced tool-calling capabilities, featuring a flexible toolsets system for organizing and managing tools.

Features

Web Tools: Search, extract content, and crawl websites
Terminal Tools: Execute commands with interactive session support
Vision Tools: Analyze images from URLs
Reasoning Tools: Advanced multi-model reasoning (Mixture of Agents)
Creative Tools: Generate images from text prompts
Toolsets System: Organize tools into logical groups for different scenarios

Setup

pip install -r requirements.txt
git clone git@github.com:NousResearch/hecate.git
cd hecate
pip install -e .

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"

# 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"])

Command Line Arguments

--query: The question or task for the agent
--model: Model to use (default: claude-opus-4-20250514)
--api_key: API key for authentication
--base_url: API endpoint URL
--max_turns: Maximum number of tool-calling iterations
--enabled_toolsets: Comma-separated list of toolsets to enable
--disabled_toolsets: Comma-separated list of toolsets to disable
--list_tools: List all available toolsets and tools
--save_trajectories: Save conversation trajectories to JSONL files

Environment Variables

Set these environment variables to enable different tools:

FIRECRAWL_API_KEY: For web tools (search, extract, crawl)
MORPH_API_KEY: For terminal tools
NOUS_API_KEY: For vision and reasoning tools
FAL_KEY: For image generation tools
ANTHROPIC_API_KEY: For the main agent model
