Modules and Flow Control Essentials

The key mental model is simple: scenarios are built by chaining modules together, and those modules fall into two broad groups:

• Flow control modules: decision-making and data-structuring tools that shape how information moves;

• Tool modules: utility helpers that support the workflow (for example, storing, counting, waiting, formatting).

Flow control modules are what separate a basic automation from a reliable system. Without these concepts, beginners often build scenarios that:

• Break when data is messy or incomplete;
• Spam outputs instead of batching logically;
• Fail to route different data types correctly;
• Cannot scale beyond simple single-path workflows.
