novyx-agent

Build AI agents with persistent memory, rollback, and audit trails.

from novyx_agent import Agent, tool

agent = Agent(
    name="Aria",
    api_key="nram_...",
    provider="anthropic",       # or "openai" or "litellm"
    model="claude-sonnet-4-6",
)

@agent.tool
def search_web(query: str) -> str:
    """Search the web for information."""
    return requests.get(f"https://api.search.com?q={query}").text

result = agent.run("What did we discuss yesterday?")
print(result)

That's it. The agent automatically recalls relevant memories before every LLM call, executes tools, and remembers the exchange for next time.

v2.0 note: provider and model are now required. Novyx is provider-agnostic — pick openai, anthropic, or litellm (for any other model). No hidden defaults.

Why novyx-agent?

Every agent framework gives you tool calling. None of them give you this:

# Roll back the agent's memory to before it went off the rails
agent.rollback("2 hours ago")

# Cryptographic audit trail — every memory operation, hash-chained
trail = agent.audit(limit=50)

# Memory health check — recall accuracy, drift, conflicts, staleness
health = agent.eval()
assert health["score"] >= 0.8, "Memory quality too low"

# Pass/fail gate for CI/CD
agent.eval_gate(min_score=0.7)

# Knowledge graph
agent.add_triple("Python", "is_a", "programming language")
triples = agent.query_triples(subject="Python")

No other agent SDK has rollback, audit trails, eval, or replay. Not OpenAI Agents SDK, not CrewAI, not LangGraph, not Pydantic AI.

Install

pip install novyx-agent

# Pick your LLM provider:
pip install novyx-agent[openai]      # OpenAI / OpenAI-compatible
pip install novyx-agent[anthropic]   # Claude
pip install novyx-agent[litellm]     # Any model via LiteLLM
pip install novyx-agent[all]         # All providers

Quick Start

1. Basic agent

from novyx_agent import Agent

agent = Agent(
    name="Assistant",
    api_key="nram_your_key",
    provider="openai",
    model="gpt-4o",
)

result = agent.run("Summarize what we've been working on")
print(result)

2. Agent with tools

from novyx_agent import Agent, tool

agent = Agent(
    name="ResearchBot",
    api_key="nram_...",
    provider="anthropic",
    model="claude-sonnet-4-6",
)

@agent.tool
def search_docs(query: str, limit: int = 5) -> str:
    """Search internal documentation."""
    return f"Found {limit} results for: {query}"

@agent.tool
def create_ticket(title: str, body: str) -> str:
    """Create a support ticket."""
    return f"Created ticket: {title}"

result = agent.run("Find docs about auth and create a ticket for the bug")
print(result)
print(f"Tools used: {[tc.tool for tc in result.tool_calls]}")

3. Agent with Claude

agent = Agent(
    name="Claude Agent",
    api_key="nram_...",
    provider="anthropic",
    model="claude-sonnet-4-6",
)

4. Agent with any model (LiteLLM)

agent = Agent(
    name="Universal",
    api_key="nram_...",
    provider="litellm",
    model="ollama/llama3",      # or "gemini/gemini-1.5-pro", "groq/llama3-70b", etc.
)

5. Memory control

from novyx_agent import Agent, MemoryConfig

agent = Agent(
    name="Selective",
    api_key="nram_...",
    provider="anthropic",
    model="claude-sonnet-4-6",
    memory=MemoryConfig(
        auto_recall=True,           # Recall before each run
        auto_remember=True,         # Remember after each run
        recall_limit=10,            # Max memories to recall
        recall_threshold=0.5,       # Minimum relevance score
        recall_tags=["project-x"],  # Only recall tagged memories
        remember_tags=["project-x"],# Tag stored memories
        remember_importance=8,      # 1-10 importance
    ),
)

6. Rollback & audit

# Oops, the agent stored bad data
agent.rollback("30 minutes ago")

# Preview before committing
preview = agent.rollback_preview("1 hour ago")
print(f"Would restore {preview['restore_count']} memories")

# Full audit trail
for entry in agent.audit(limit=20):
    print(f"{entry['action']} at {entry['timestamp']}")

7. Eval gates for CI/CD

health = agent.eval()
print(f"Memory score: {health['score']}")
# score = 0.7*recall + 0.2*freshness + 0.1*consistency

# Hard gate — raises if below threshold
agent.eval_gate(min_score=0.7)

8. Direct Novyx access

# Full SDK access for advanced operations
nx = agent.novyx
nx.dashboard()
nx.cortex_run()
nx.replay_timeline(hours=24)

Architecture

novyx-agent
├── agent.py      — Agent class (run loop, memory integration)
├── tools.py      — @tool decorator (auto-schema from type hints)
├── types.py      — Pydantic models (ToolDef, RunResult, configs)
├── providers.py  — LLM adapters (OpenAI, Anthropic, LiteLLM)
└── __init__.py   — Public API

The run loop:

1. Recall — semantic search over Novyx memories relevant to the prompt
2. Build context — system prompt + recalled memories + conversation history + user message
3. LLM loop — call the model → if tool calls, execute them → repeat until text response
4. Remember — store a summary of the exchange as a new memory
5. Return — RunResult with output, tool calls, memory stats, token usage

@tool

@tool
def my_function(param: str, count: int = 5) -> str:
    """Description becomes the tool description."""
    return "result"

Automatically extracts: name, description (from docstring), parameters (from type hints), required/optional (from defaults).
