agentnova 0.4.5

⚛️ AgentNova - A minimal, hackable agentic framework for local LLM inference

⚛️ AgentNova R04.5

Status: Alpha

A minimal, hackable agentic framework engineered to run entirely locally with Ollama or BitNet.

Inspired by the architecture of OpenClaw, rebuilt from scratch for local-first operation.

Installation

# Latest Development Release
pip install git+https://github.com/VTSTech/AgentNova.git --force-reinstall

# Last Stable (as stable as Alpha can be) Release
pip install agentnova

Quick Start

CLI Usage

# Run a single prompt
agentnova run "What is 15 * 8?" --tools calculator

# Interactive chat
agentnova chat -m qwen2.5:0.5b --tools calculator,shell

# Autonomous agent mode
agentnova agent -m qwen2.5:7b --tools calculator,shell,write_file

# Use OpenAI Chat-Completions API
agentnova chat -m qwen2.5:0.5b --api openai

# List available models
agentnova models

# List available tools
agentnova tools

Python API

from agentnova import Agent
from agentnova.tools import make_builtin_registry

# Create tools
tools = make_builtin_registry().subset(["calculator", "shell"])

# Create agent
agent = Agent(
    model="qwen2.5:0.5b",
    tools=tools,
    backend="ollama",
)

# Run
result = agent.run("What is 15 * 8?")
print(result.final_answer)
print(f"Completed in {result.total_ms:.0f}ms")

Chat-Completions Streaming

from agentnova.backends import get_backend
from agentnova.core.types import ApiMode

# Use Chat-Completions mode with streaming
backend = get_backend("ollama", api_mode=ApiMode.OPENAI)

for chunk in backend.generate_completions_stream(
    model="qwen2.5:0.5b",
    messages=[{"role": "user", "content": "Hello!"}],
    response_format={"type": "json_object"}
):
    print(chunk["delta"], end="", flush=True)

Skill License Validation

from agentnova.skills import validate_spdx_license, parse_compatibility

# Validate SPDX license identifier
valid, msg = validate_spdx_license("MIT")  # (True, "Valid SPDX identifier: MIT")
valid, msg = validate_spdx_license("Custom")  # (False, "Unknown license...")

# Parse compatibility requirements
compat = parse_compatibility("python>=3.8, ollama")
# Returns: {"python": ">=3.8", "runtimes": ["ollama"], "frameworks": []}

Multi-Agent Orchestration

from agentnova import Agent, Orchestrator, AgentCard

orchestrator = Orchestrator(mode="router")

# Register specialized agents
orchestrator.register(AgentCard(
    name="math_agent",
    description="Handles mathematical calculations",
    capabilities=["calculate", "math", "compute"],
    tools=["calculator"],
))

orchestrator.register(AgentCard(
    name="file_agent",
    description="Handles file operations",
    capabilities=["read", "write", "file"],
    tools=["read_file", "write_file"],
))

# Route tasks to appropriate agent
result = orchestrator.run("Calculate 15 * 8 and save to file")

Tool Support Levels

AgentNova supports three levels of tool use:

1. Native — Models with built-in function calling (qwen2.5, llama3.1+, mistral, granite, functiongemma)
2. ReAct — Text-based tool use via reasoning prompts (qwen2.5-coder, qwen3)
3. None — Pure reasoning without tools

Tool support is auto-detected by running agentnova models --tool-support. Results are cached in ~/.cache/agentnova/tool_support.json.

# Test and cache tool support for all models
agentnova models --tool-support

# Re-test (ignore cache)
agentnova models --tool-support --no-cache

You can also force ReAct mode:

agent = Agent(model="qwen2.5:0.5b", force_react=True)

Model Families

Configured model families with optimized prompts:

• qwen2.5 — Native tool support, excellent performance
• llama3.1/3.2/3.3 — Native tool support
• mistral/mixtral — Native tool support
• gemma2/gemma3 — ReAct mode, special prompting
• granite/granitemoe — Native tool support
• phi3 — Native tool support
• deepseek — Native with <think/> tag handling

Security Features

Built-in security for safe operation:

• Command blocklist — Blocks dangerous shell commands (rm, sudo, etc.)
• Path validation — Prevents access to sensitive directories
• SSRF protection — Blocks requests to local/internal URLs
• Injection detection — Detects shell injection patterns

Configuration

Environment variables:

# Backend URLs

Benchmark Results (Quick Diagnostic)

Model	Score	Time	Tool Support
functiongemma:270m	5/5 (100%)	~20s	native
granite4:350m	5/5 (100%)	~50s	native
qwen2.5:0.5b	5/5 (100%)	38s	native
qwen2.5-coder:0.5b	5/5 (100%)	93s	native
qwen3:0.6b	5/5 (100%)	70s	react
deepseek-r1:1.5b	5/5 (100%)	~305s	native

All tested models achieve 100% on the Quick Diagnostic. Native models are ~2x faster than ReAct models due to direct API tool calling.
