kinetgraph

A pure, event-sourced ECS framework for building autonomous agents over Redis Streams.

The framework models agent state as a deterministic fold over an immutable event log. Side effects (LLM calls, HTTP requests, tool execution) run outside the fold, in isolated workers. The result is an agent whose entire history is replayable, whose state is a pure function of events, and whose tool calls are at-most-once even under at-least-once delivery.

When to use

• You need agents whose decisions are auditable and replayable from first principles.
• You want to run LLM calls in process-pool workers so the event loop never blocks.
• You need idempotent tool execution across retries and dispatcher restarts.
• You want a single Redis Stream as the source of truth, with no separate state DB.
• You are building multi-tenant systems where each agent has its own isolated event log.

Install

uv add kntgraph

Optional extras (install only what you need):

uv add "kntgraph[cli]"          # knt scaffold CLI
uv add "kntgraph[falkordb]"     # graph projection + Cypher (FalkorDB)
uv add "kntgraph[ollama]"       # local LLM / embeddings
uv add "kntgraph[gliner]"       # GLiNER2 NER — intent routing and PII redaction
uv add "kntgraph[api]"          # HTTP gateway (FastAPI)
uv add "kntgraph[crypto]"       # Ed25519 event signing
uv add "kntgraph[llm]"          # LiteLLM adapter
uv add "kntgraph[all-runtime]"  # everything above

To install the unreleased main between tagged releases: uv add "kntgraph @ git+https://github.com/kinetgraph/kinetgraph.git". Tagged releases on PyPI are the canonical, supported path.

Hello world

import asyncio
from kntgraph.core.event import Event
from kntgraph.core.world import World


async def main() -> None:
    e1 = Event.create(
        event_type="agent.spawned",
        agent_id="a-1",
        event_class="lifecycle",
    )
    e2 = Event.create(
        event_type="document.received",
        agent_id="a-1",
        event_class="domain",
        data={"doc_id": "NF-001"},
    )
    world = World.fold([e1, e2], tick=2)
    print(world.agents["a-1"].operational_phase)  # "spawned"
    print(world.agents["a-1"].domain_phase)       # "document.received"


asyncio.run(main())

The agents sub-module ships concrete LLM, cache, and PII adapters on top of the framework:

from kntgraph.agents.tools import LiteLLMToolWorker

worker = LiteLLMToolWorker()
result = await worker.invoke(
    system="You are a helpful assistant.",
    user="What is the capital of France?",
    idempotency_key="k1",
)
# ``result`` is a ``Result[dict, ToolError]``; the dict
# envelope carries ``text`` / ``model`` / ``usage`` /
# ``finish_reason`` / ``cost_usd`` / ``latency_ms``.

What the framework provides

CLI scaffold

knt is the first-party CLI for scaffolding ADR-compliant projects and contexts:

# Install with the [cli] extra
uv add "kntgraph[cli]"

# Scaffold a new application
knt init project my_platform --use-intent-http

# Or choose a routing mode explicitly
knt init project my_platform --routing-mode external
# external   — routes intents from outside the agent boundary
# autonomous — agent resolves intents internally
# collaborate — multiple agents coordinate on a shared intent

# Add domain contexts and systems
cd my_platform
knt new context weather
knt new system weather.WeatherRouter
knt new tool weather.OpenMeteoApi

# Check for framework drift in boilerplate
knt upgrade check

See the CLI Guide for a full walkthrough.

Configuration

All settings live under the KNT_ env-var prefix and are loaded via Pydantic v2 BaseSettings. The canonical schema is Settings in kntgraph.infra.config.
