Controlled mitosis for AI agents — dynamic, effort-scored, recursive task decomposition with regulated division.

🧬 Mitosys

Controlled mitosis for AI agents — dynamic, effort-scored, recursive task decomposition with regulated division.

Mitosys is a Python SDK and CLI that routes complex tasks through the Mitosys backend: an LLM-powered multi-agent system that breaks tasks into parallel sub-tasks, runs them concurrently, and synthesizes a final answer.

Uncontrolled division is cancer. Mitosys is controlled mitosis.

pip install mitosys

Quick Start

import mitosys

# Sync — great for scripts and notebooks
result = mitosys.run("Analyze Q3 sales data across all regions")
print(result.final_answer)
print(f"Used {result.total_agents} agents across {result.max_depth} levels")

# Async
import mitosys

result = await mitosys.arun("Analyze Q3 sales data")
print(result.final_answer)

# Streaming — get live events as the lifecycle progresses
import mitosys

async for event in mitosys.astream("Write a comprehensive market report"):
    if event.type == "effort":
        print(f"Effort: {event.score}/10  →  {event.recommended_agents} agents")
    elif event.type == "spawn":
        print(f"Born: {event.agent}")
    elif event.type == "final":
        print(event.final_answer)

Configuration

Method	Example
Default	https://lumidoc-mitosys-backend.hf.space
Environment variable	export MITOSYS_URL=http://localhost:8000
Explicit argument	MitosysClient(url="http://localhost:8000")

from mitosys import MitosysClient

client = MitosysClient(
    url="https://my-self-hosted-mitosys.example.com",
    timeout=180,
)
result = await client.arun("Analyze our Q3 sales data")

Resolution order: explicit url= → $MITOSYS_URL → built-in default.

Typed Result Objects

result = mitosys.run("...")

result.task             # str — the original task
result.final_answer     # str — the synthesized answer
result.sub_tasks        # list[SubTask]  — each has .subtask and .effort_hint
result.sub_results      # list[SubResult] — each has .agent, .subtask, .result
result.tree             # AgentTree — walk() yields every node depth-first
result.effort           # EffortScore — .score, .breadth, .depth, .recommended_agents
result.total_agents     # int — how many agents ran in total
result.max_depth        # int — deepest recursion level reached
result.elapsed_seconds  # float
result.raw              # dict — the original backend payload (for power users)

Framework Integration

AutoGen

from mitosys.adapters.autogen import MitosysTool
from autogen_agentchat.agents import AssistantAgent

mitosys_tool = MitosysTool()
agent = AssistantAgent(
    name="researcher",
    model_client=...,
    tools=[mitosys_tool.as_function_tool()],
)
# When the agent decides a task is too complex, it delegates to Mitosys.

pip install mitosys[autogen]

LangGraph

from mitosys.adapters.langgraph import mitosys_node
from langgraph.graph import StateGraph

graph = StateGraph(dict)
graph.add_node("delegate_complex", mitosys_node())
# State must contain "task"; result is written to "mitosys_result".

pip install mitosys[langgraph]

CrewAI

from mitosys.adapters.crewai import MitosysAgent
from crewai import Crew, Task

heavy = MitosysAgent(role="Heavy task specialist")
crew = Crew(agents=[heavy], tasks=[Task(description="...", agent=heavy)])
crew.kickoff()

pip install mitosys[crewai]

---

CLI

The mitosys command is included with the package and makes the whole lifecycle visible in your terminal:

# Stream the live lifecycle (default)
mitosys run "Write a comprehensive analysis of renewable energy trends"

# Wait for the full result (no streaming)
mitosys run "..." --no-stream

# Pipe the raw JSON to jq
mitosys run "..." --json | jq '.final_answer'

# Check backend health
mitosys health

# Show version + configured URL
mitosys version

Flags for run:

Flag	Description
--url URL	Override backend URL
--no-stream	Blocking POST /run (no live events)
--json	Raw JSON to stdout; lifecycle to stderr
--timeout SEC	HTTP timeout (default 120)

---

How It Works

1. Your task is sent to the Mitosys backend.
2. An effort scorer evaluates breadth × depth (1–10) and recommends how many agents to spawn.
3. The parent agent divides the task into sub-tasks.
4. Each sub-agent self-assesses its sub-task. If it's too complex, it proposes recursive division.
5. The regulator (parent LLM) approves or denies each proposal — keeping the tree bounded.
6. Approved sub-agents spawn children; all leaf agents execute concurrently.
7. Results are collected, agents are destroyed, and the parent synthesizes a final answer.

What's New in v0.3.0

• SDK-first — import mitosys is now the primary interface; the CLI is one entry point among many.
• Typed result objects — MitosysResult, AgentTree, EffortScore, SubTask, SubResult with autocomplete-friendly properties.
• Typed event stream — MitosysEvent with .score, .agent, .final_answer, etc.
• Framework adapters — AutoGen, LangGraph, CrewAI (optional extras).
• Typed exceptions — MitosysNetworkError, MitosysBackendError; no httpx leakage.
• Package renamed from mitosys-cli → mitosys.

What's New in v0.2.0

• Effort scoring, recursive division, regulator approval, agent tree — see CHANGELOG.

---

Roadmap

• Rate limiting and concurrency controls
• More framework adapters (LlamaIndex, Semantic Kernel, Haystack)
• Self-hosted deployment guide
• Streaming progress callback API (non-async)
• Token usage reporting per agent

Upgrading from 0.2.0

pip uninstall mitosys-cli
pip install mitosys

The mitosys CLI command is identical. Only the Python import path changes:

# Before (v0.2.0)
from mitosys_cli.cli import app

# After (v0.3.0)
from mitosys.cli.main import app
