In the landscape of modern software, automation is king. We build scripts, connect APIs, and orchestrate services to streamline business processes. But as these systems grow in complexity, they often become fragile. A single network hiccup, a temporary API outage, or an unexpected data format can bring a multi-step process to a grinding, partial halt, leaving your system in an inconsistent state.
What if there was a better way to build? A way to define tasks that are guaranteed to execute reliably, every single time?
This is the promise of agentic workflows, a new paradigm in automation. And at their core is a powerful, simple concept: the Atomic Action.
Think of an atomic action as the smallest, indivisible unit of work in any process. It's a single, encapsulated task designed with one critical principle in mind: it either succeeds completely, or it fails cleanly without any side effects.
Much like a database transaction, there's no "in-between" or "partially done."
This all-or-nothing guarantee is the foundation of building robust, fault-tolerant systems. With the .do platform, you define these atomic units of work as code, creating a library of reusable, reliable building blocks for any workflow you can imagine.
You might be thinking, "Isn't this just a fancy name for an API endpoint?" While actions on .do are triggered via an API, they are fundamentally more powerful than standard, stateless API calls.
Here’s how they differ:
The true power of the .do platform lies in defining these actions directly in your codebase. You're not clicking around in a complex UI a thousand miles from your source control; you're writing clear, testable, and version-controlled code.
Here’s a simple example in TypeScript of an action that sends a welcome email:
import { Action, client } from '@do-sdk/core';
// Define an atomic action as code
const sendWelcomeEmail = new Action({
name: 'send-welcome-email',
handler: async (inputs: { userId: string }) => {
const user = await db.users.find(inputs.userId);
if (!user) {
throw new Error('User not found.');
}
await email.send({
to: user.email,
subject: 'Welcome to .do!',
body: `Hi ${user.name}, welcome aboard!`
});
return { success: true, messageId: '...' };
}
});
// Execute the action via the SDK
const result = await client.action('send-welcome-email').invoke({
userId: 'usr_12345'
});
This action is now a reusable, API-driven component. You can invoke it from anywhere in your application, confident that the underlying logic for finding a user and sending an email will execute atomically.
Atomic Actions are the fundamental building blocks. The real magic happens when you chain them together to model complex business processes. On the .do platform, you can easily sequence, parallelize, and orchestrate multiple Actions into a fault-tolerant Workflow.
This sequence becomes an autonomous agent—a "Service-as-Software"—that executes a critical business process. If the update-crm-record Action fails, the platform can automatically retry it. If it continues to fail, the entire process halts cleanly, and you are alerted without leaving your user's account in a partially provisioned state.
Adopting an atomic, action-based approach to workflow automation provides clear advantages:
The next generation of business process automation won't be built on brittle scripts and simple API calls. It will be powered by intelligent, autonomous agents built on a foundation of reliable, auditable, and scalable components.
The atomic action is that foundational component.
