Why automations have to stay maintainable

At first, an automation saves you a manual step. As soon as several steps come together, though, a new task appears: understanding the process and putting it right when errors occur.
An invented collection of your own craft notes explains this well. Every evening, new text files are to be added to an overview. The normal path is simple: read the folder, detect new files, add titles, save the overview.
The interesting part starts with the error
What happens if a file cannot be read? If the same title appears twice? Or if the overview is currently open in another program? A usable process has understandable answers to these questions.
It could skip the affected file, record the reason and process the remaining entries. Or it stops the task if the overview cannot be saved safely. What matters is that the state stays visible and that the next run does not quietly create duplicate entries.
The n8n documentation on executions shows an important aspect of such systems: individual runs must be inspectable. For your own setup, this raises the practical question of which information is actually needed for troubleshooting.
An understandable process can be handed over
Trigger, permitted steps and result should fit on a short page. A time limit and the handling of retries belong there too. An agent should recognise when another attempt will not help.
When choosing a tool, later maintenance therefore counts as well. A connection between two services is quickly demonstrated. A process is only pleasant when, after a break, you still understand what it does and why a particular run stopped.
