Factory's "Missions" system tackles AI agents' declining performance over time by dividing tasks into smaller chunks managed by fresh agents with specific goals, ensuring consistent reliability across multi-day operations.
When it comes to handling complex, multi-day tasks in AI systems, a single agent often struggles to maintain focus and reliability. This is where Factory's "Missions" system shines. It breaks down large workloads into manageable units, each handled by fresh agents with narrowly scoped goals, shared state, and explicit validation. Here’s how it works under the hood.
The core observation driving Missions' design is that agents are highly reactive to their context. As an agent processes more information, its focus and reliability can diminish. This is problematic for long-term, complex tasks that require consistent performance over days or even weeks.
To address this, Missions splits large projects into smaller, focused missions. Each mission is designed to be self-contained, ensuring that the agents handling them remain reliable and efficient. This approach allows for better scalability and reliability in autonomous work.
Agent Context Management:
Separation of Concerns:
Test-Driven Development (TDD) at Two Levels:
Shared State:
Missions is built on a microservices architecture, which enables flexibility and scalability. Here’s a breakdown of the key components:

Agent Services:
Validation Service:
Let’s consider a real-world example: automating a data analysis project.
Data Collection:
Data Preprocessing:
Analysis:
Report Generation:
The future of Missions includes several exciting developments:
By breaking down large, complex tasks into smaller, manageable units, Missions ensures that each step is handled reliably and efficiently. This approach not only improves the overall reliability of AI systems but also paves the way for more sophisticated autonomous work in the future.

About the author
Kai built ML infrastructure at a Bay Area startup before developing an obsession with transformer architectures and inference optimisation that eventually pulled him out of product work entirely. A stint at a compute research lab sharpened his instinct for what actually matters in a model release versus what is marketing. He writes from the inside — from the perspective of someone who has debugged the systems he is describing at three in the morning. He is allergic to hype and instinctively drawn to the unglamorous plumbing questions that everyone else skips over.
