In the world of automation, we've all been there. A complex script, meticulously crafted to handle a multi-step business process, crumbles at the first sign of an unexpected error. Hours are spent untangling a web of partial states, trying to figure out if the user was created but the email failed, or if the report was generated but couldn't be uploaded. Your automation, meant to be a pillar of efficiency, has become a house of cards.
What if we changed our perspective? What if we stopped building monolithic scripts and started composing our processes from small, indestructible, and guaranteed units of work?
This is the core philosophy behind action.do. We believe the future of robust automation and agentic workflows isn't about writing longer scripts; it's about defining better building blocks.
The Building Block of Automation: Encapsulate any single, repeatable task into a powerful, API-callable action. Simplify complexity and build robust, scalable agentic workflows from the ground up.
In the context of action.do, an atomic action is the smallest, indivisible unit of work in a workflow. It’s not just a function or a task; it's a guarantee. The term "atomic" comes from the principle that the action either completes successfully in its entirety, or it fails completely, leaving no side effects or partial results.
Think of it like a bank transaction: when you transfer money, you can't just debit one account without crediting another. Both operations must succeed for the transaction to be valid. If one fails, the entire transaction is rolled back. Atomic actions bring this level of integrity to every step of your workflow, whether it's "send an email," "create a user record," or "transcode a video."
This philosophy is our badge: Simple. Atomic. Powerful.
Defining an action should be as simple as writing a function, but with the added benefits of structure, validation, and discoverability. Here’s how you can define an action to send a welcome email using our SDK:
import { action } from '@do-sdk/core';
export const sendWelcomeEmail = action({
name: 'send-welcome-email',
description: 'Sends a welcome email to a new user.',
inputs: {
to: { type: 'string', required: true },
name: { type: 'string', required: true }
},
handler: async ({ inputs, context }) => {
const { to, name } = inputs;
// Email sending logic (e.g., using an API like SendGrid or AWS SES)
console.log(`Sending welcome email to ${name} at ${to}`);
// Simulate a successful API call
return { success: true, messageId: 'xyz-123' };
},
});
Let's break down what makes this so powerful:
Adopting an atomic approach to task automation isn't just a stylistic choice; it provides fundamental advantages, especially in complex, agentic systems.
When an action fails, it fails cleanly. You don't have to worry about a process being left in a messy, indeterminate state. The orchestrating workflow knows precisely which block failed and can trigger a retry, an alert, or a fallback path with confidence.
Large, monolithic scripts are difficult to scale. With atomic actions, each unit is independent. Need to handle 10,000 emails per minute? You can scale the send-email action independently of the create-user action. This granular control is key to building efficient, cost-effective systems.
This is where the magic happens. Once you've defined send-welcome-email, you never have to write that logic again. You can call it from your user onboarding workflow, your marketing automation, or a manual admin tool. By creating a library of actions, you are quite literally turning your business processes into reusable code (Business-as-Code), promoting the DRY (Don't Repeat Yourself) principle across your entire organization.
A failure in a workflow is no longer a cryptic stack trace from a 1000-line file. It's a clear signal: "Action generate-report failed with input X." You can isolate, test, and fix that single action without impacting the rest of the system.
It's important to understand the distinction:
Actions are the fundamental, reusable components. Workflows provide the structure and logic to connect them in a meaningful sequence.
Stop wrestling with fragile scripts and start composing powerful, resilient automations. By focusing on atomic actions, you're not just automating tasks; you're building a reliable, scalable, and maintainable foundation for all your agentic workflows.

Q: What is an 'atomic action' in the context of .do?
A: An atomic action is the smallest, indivisible unit of work in a workflow. It represents a single, well-defined task, like 'send an email' or 'create a user record', ensuring that it either completes successfully or fails entirely, without partial states.
Q: How is an action.do different from a full workflow.do?
A: An action.do represents a single task. A workflow.do is a collection of one or more actions orchestrated to achieve a larger business process. Actions are the building blocks; workflows are the blueprints that connect them.
Q: Can I reuse actions across different workflows?
A: Absolutely. Actions are designed to be modular and reusable. You can define an action once, like 'generate-report', and call it from any number of different workflows, promoting DRY (Don't Repeat Yourself) principles in your automations.
Q: What kind of logic can I put inside an action's handler?
A: The handler can contain any Node.js/TypeScript logic. This includes making API calls to third-party services, performing data transformations, interacting with databases, or executing any custom business logic required to complete the task.
